A: Yes, our speed bumps are made of high-quality, durable materials that are designed to withstand harsh outdoor conditions. They are weather-resistant, UV-resistant, and can withstand heavy traffic and extreme temperatures.

Speed bumps are raised sections of roads designed to reduce vehicle speed, typically in residential areas or near schools. They are smaller than speed humps and cause a vehicle to slow down to a near stop. They improve road safety by preventing reckless driving and reducing accidents in high-traffic pedestrian zones.

3. Some Piping BasicsIt is very important that you understand what you are looking at and the consequences of being wrong when it comes to evaluating piping systems. Let’s start with the pipe itself. Most pipe you will ever encounter starts its life at a steel mill in sheet form. In many cases, the mill rolls the sheet into tubes and welds it. There are different piping designations, an example is ASTM A 53B, ASME SA 53 B. ASTM means American Society of Testing Materials, (www.astm.org), SA 53 B, is the designation for plain black steel pipe mostly used in the industry. Piping also comes in different schedules (or wall thicknesses). The schedule or thickness would be schedule 40 or 80. The wall thickness for typical 6 inches schedule 40 increases from 0.280 inches to 0.432 inches for schedule 80. Schedule 40 is what’s commonly called for in B31.1 for pressure piping in service conditions that apply to this article. B31.1 and ASME code, Section I, have calculations that the designers would use to determine the safe working pressure of the piping based on its type, thickness and minimum diameter. Schedule 80 is called out as good practice for most condensate systems since they are a severe duty as compared to steam. Condensate is likely to contain carbonic and or other mild acids. This tends to erode condensate piping over time. Making this kind of piping thicker from the start builds in a factor of safety.

A: Speed bumps can cause damage to vehicles if they are hit at high speeds or if the suspension is not in good condition. However, if drivers navigate over speed bumps at a reasonable speed, there should not be any damage to the vehicle.

4. Flanges and Their RatingsYou also need to be aware of flange pressure ratings. The ratings and certification information are usually stamped on the circumference of the flange. A 150 LB flange indicates a pressure temperature rating. This is not the MAWP of the flange, but a designation which allows a certain pressure use based upon the installation and temperature to be encountered. Pressure /Temperature ratings can be found in ASTM A 105 B 16.5 specification tables (www.astm.org).

Speed bumps and speed humps both reduce vehicle speed, but they differ in design and purpose. Speed bumps are more abrupt, requiring vehicles to slow almost to a stop, and are typically used in parking lots.

Speed humps are wider and less severe, allowing for smoother travel at lower speeds, commonly found in residential areas.

A: Vertical traffic control management barriers such as speed bumps and speed humps are physical bumps in the road that startle the occupants of a vehicle travelling too quickly over them and offer great ground protection. Great to slow traffic and for road safety They are the most widely utilised traffic calming structural elements. Asphalt, concrete, plastic, rubber, and metal can all be used to create them.

1. Steam Piping Ratings of Boiler SystemsIn most states and jurisdictions, steam piping is classified as high pressure piping when it exceeds 15 PSIG. The main construction code used to define high pressure piping issues and requirements for construction and installation is published by the American Society of Mechanical Engineers (ASME) Section I (Power Boiler) and ASME code B31.1 (Pressure Piping) codes. You can obtain copies of these code sections at www.asme.org or by calling 1-800-THE-ASME.

A: Yes, speed bumps are an effective way to reduce vehicle speeds, especially in areas where speeding is a problem. They are also useful for slowing down drivers in areas where pedestrians are present, such as near schools and residential areas.

A: There are several types of speed bumps available, including rubber speed bumps, asphalt speed bumps, and concrete speed bumps. Each type has its own advantages and disadvantages, and the right choice will depend on your specific needs and budget.

A: To maintain speed bumps, you should regularly inspect them for damage or wear and tear. You should also keep them clean and free of debris, and repair any damage as soon as possible to prevent further deterioration.

Rubber speed bumps are durable, cost-effective, and easy to install. They offer flexibility for temporary or permanent use and are environmentally friendly, as many are made from recycled materials. Unlike asphalt or concrete, rubber versions are less prone to wear and can be easily removed or relocated when necessary.

A: Yes, our speed bumps are designed to comply with local regulations for traffic calming measures. However, we recommend checking with your local authorities to ensure compliance with specific requirements.

8. Valve and fittings ratingsValves and fittings should have their pressure rating cast into them or marked as required by the applicable material specification. Many pipe fittings are marked with a manufacturer’s logo or insignia, size, and schedule rating (example 6 inches SA 234 Gr WPB or 1 inches 3000M A105 B 16.5 with the logo). The pressure rating must be at least equal to the design MAWP. Again ASME/ASTM SA/A 234 or SA/A 105 B 16.5 give the specific requirements for these fittings. Valves will also be marked with their pressure rating along with the type of service permitted to be used. The ASME codes specify which types of valves and fittings are permitted to be used and their proper service applications in pressure piping applications.

This document seeks to provide methods for screening high pressure (below 300 psig) piping systems, that may normally be encountered in industrial steam plants, to identify safety issues related to the design and/or installation of pipe, valves, flanges, and components used in these systems. The following is not an all inclusive guide to safe practices, but instead attempts to give some insight for understanding and conducting a simple screening of a steam piping system. This review of what is installed is important for every steam plant operator to help make sure that an unexpected accident is not waiting the next time someone opens a valve or puts a steam line into service.

A: Yes, speed bumps can be used in parking lots to reduce speeds and improve safety for pedestrians and drivers. They are often used to control traffic flow and prevent accidents in high-traffic areas.

A: Speed bumps can create safety concerns if they are not installed properly or if they are hit at high speeds. However, if they are installed and maintained correctly, they can be a safe and effective way to slow down traffic and improve safety.

Traffic calming

7. Joints and Joining MethodsPipe gets assembled to other pipe, fittings, and flanges by either welding or threading. There are specific code requirements that describe when it is permissible to thread or when welding must be used. Within the welding world, you also need to be aware of several other possibilities. Flanges and fittings come as either slip on or weld neck. Slip on fittings are just that, slipped onto the end of the pipe. The flange is then welded up around the contact points on the inside and outside of the pipe and the flange. Slip on flanges are not considered as strong a joint as weld neck or butt welded connections. In the case of a butt welded or weld neck flange the two pieces, flange and pipe, are prepped and then welded together with full penetration through the weld construction (a welder carefully lays a bead and builds up layers around the entire surface of the gap between the two pieces). Socket welding is a term used to describe when a slip on fitting, usually used for small diameters, is inserted into the fitting until it bottoms out. Then the pipe is pulled back from the bottom and welded to the fitting. Failure to pull the pipe back can cause welds to fail from stresses.

A: The lifespan of a speed bump will depend on several factors, including the material it is made from, the amount of traffic it sees, and the weather conditions in the area. Generally, rubber speed bumps can last up to 10 years, while asphalt and concrete speed bumps can last up to 20 years or more.

A: The installation process for speed bumps will depend on the type of speed bump you choose, as well as the surface you are installing it on. For example, asphalt and concrete speed bumps require professional installation, while rubber speed bumps can be installed using adhesive or anchor bolts.

A: A speed bump cannot be avoided. Even if there aren't any clearly delineated lanes. The entire speed bump must also be 12 feet long or more, according to the law. The "LOW SPOT" you're all talking about is for drainage, not two-wheelers.

6. Fastener Issues, When a Bolt is Not Just a BoltFasteners could be another problem area. Fasteners should be rated to at least a grade 8. This means they have a tensile strength that could withstand the force that must be applied for the proper assembly of the components. There is also a standard marking system for fasteners. When you look at a bolt head you should be able to see markings that identify its grade or rating. Be aware that cheap fasteners can mean forgeries that can cost someone their life. You can find out more about fasteners and ratings by going to the National Fastener Distributor Association’s website at www.nfda-fastener.org. Also, be aware of threaded rods and studs. Studs are not simply some supply house off the shelf threaded rod cut to size. Studs should be marked with a stamping in the end that indicates they are a special grade and type of material that is of sufficient tensile strength. They might have a marking like “AB or HV” stamped into the end.

A: We offer a variety of speed bumps, including rubber speed bumps, plastic speed bumps, and steel speed bumps. Our speed bumps are available in different sizes and designs to meet your specific needs.

Speed table

A: Speed bumps work by forcing drivers to slow down and navigate over the raised area, which creates a discomfort or jolt that encourages them to reduce their speed. This makes them an effective traffic calming solution in areas where speeding is a problem.

A: Yes, there are several alternatives to speed bumps for traffic calming, including speed cushions, chicanes, and roundabouts. The right choice will depend on the specific needs of your area, as well as your budget and other constraints.

5. Flange MaterialsFlange materials can also be tricky. You always want to make sure you are using carbon steel flanges with the proper rating, A 105 B 16.5 is a typical carbon steel flange used in pressure piping applications. Cast Iron flanges are too brittle and could break in this kind of application.

A: Our speed bumps are designed to be easy to install and can be installed by anyone with basic tools and DIY skills. They come with all the necessary hardware and instructions, and most can be installed in just a few hours.

There it is 10 simple rules that might keep you or someone else alive. Trust me, you do not want to be around a piece of piping or a flange that lets go. We are talking the immediate removal of flesh, displacement of oxygen, and burns over so much of your body that it will be over in a painful matter of hours. This stuff is nothing to play with so make sure the job is being done right, use professionals, and know what you are getting. Also, take a little time to use the information above and know more about what you already have.

9. Welding ConsiderationsWelding on pipe, fittings, flanges, and pressure vessels must only be done by someone with the proper credentials. Welding on pressure piping must be performed following qualified welding procedure specifications. It is the responsibility of the installer to have welding procedure specifications that are certified to meet the applicable ASME code construction;(refer to ASME code Section I and B 31.1 and ASME Code Section IX for welding procedure specifications). The National Board Inspection code which is required for repairs of pressure equipment also includes AWS (American Welding Society, www.aws.org) standard welding procedures. Every detail of AWS standard welding procedures must be followed when welding or the weld can be deemed to not be a qualified weld and in jeopardy of having to be removed.

A: Speed bumps and speed humps are both traffic calming devices, but they differ in design and purpose. Speed bumps are shorter and more abrupt, while speed humps are longer and more gradual. Speed bumps are designed to slow down vehicles to a complete stop, while speed humps are designed to encourage drivers to reduce their speed.

2. MAWP – What is it?The piping, valves, and components of any high pressure piping system have to be rated for the MAWP, or the Maximum Allowable Working Pressure, of the boiler. ASME requires a nameplate be affixed to the boiler with this information on it. The piping attached to the steam discharge flange must also be built to withstand the MAWP that the boiler can generate. In multiple boiler installations, the design rules typically apply to all piping through the second stop valve from the discharge flange of the boiler and are governed by ASME Code Section I and B31.1. After the discharge of the second valve, the piping must be rated as required by the applicable jurisdiction. This may be the MAWP of the boiler or at least the setpoint of the highest safety relief valve protecting the system. There are also specific rules for stamping or identifying the piping which falls within the code boundary jurisdiction of the boiler. Typically the S/N (serial number), Certified By and Pressure will be stamped or a nameplate banded to the pipe indicating this information.

A: Speed bumps are traffic calming devices that are designed to slow down vehicles by creating a raised area on the road surface. They are typically made from rubber, asphalt or concrete, and are used to improve safety in areas where traffic speed needs to be reduced.

A: We offer a 30-day return policy for our speed bumps. If you are not satisfied with your purchase for any reason, you can return it for a full refund or exchange.

At Street Solutions UK we offer an extensive range of speed ramps (speed cushion), speed bump kits and kerb ramp products to suit a variety of site tasks. Speed bump kits or speed bumps are popular traffic calming measures and wheel stops, they are mostly used around housing estates, shopping centres, construction sites, logistic and manufacturing sites, schools, and hospitals. The use of a speed cushion or parking post increases safety by slowing the flow of traffic in areas where there is a larger volume of pedestrian footfall.

A: Yes, speed bumps are regulated by various federal, state, and local laws and regulations. It is important to ensure that any speed bumps you install are compliant with these regulations to avoid any legal issues.

A: Yes, speed bumps are designed to be weather-resistant and can withstand a range of weather conditions, including rain, snow, and extreme temperatures. However, extreme weather conditions can cause damage to speed bumps over time.

A: To choose the right speed bump for your needs, you should consider factors such as traffic volume, vehicle speeds, and the type of road surface. You should also consider the material, size, and shape of the speed bump, as well as any specific regulations in your area.

Along with the ASME required stamping, the National Boards registration numbers might also be found. The National Board of Boiler and Pressure Vessel Inspectors is located in Columbus, OH. They maintain a database of all registered pressure items. You can call them with the National Board number, original manufacturer and year built as indicated on a nameplate, and they can tell you lots about what you have and the original design. They can be reached at www.nationalboard.org. This is very important when inspecting, repairing or replacing items. The proper repair or replacement should ensure the same safety integrity as when the boiler, pressure piping or pressure equipment was originally constructed (If not better).

A: The main benefits of speed bumps are that they reduce vehicle speeds, improve safety for pedestrians and cyclists, and encourage drivers to be more cautious on the road. They can also be an effective way to reduce noise pollution and improve air quality in residential areas.

In the UK, speed bumps must comply with specific regulations to ensure safety. They can be up to 100mm high and are typically placed in areas with a speed limit of 30 mph or less. Proper signage is required to warn drivers, and bumps must be spaced according to legal guidelines to prevent vehicle damage and ensure safe traffic flow.

A: Speed bumps are used to slow down vehicles and reduce their speed in areas where pedestrian or vehicular traffic is high. They are an effective way to improve safety and reduce the risk of accidents.

Welders must also be qualified to the requirements of ASME code Section IX. Once qualified and certified, the welder can only weld within the variables listed on their welder’s performance qualification record. The welder must also weld within the process at least once every 6 months or the qualification expires. Records must be kept to prove that the welder had welded at least once every 6 months. Welders will mark their welds with stamping to identify which person welded which joint. This stamping could be there on your system but possibly obscured with insulation.

Speed bumps work by forcing drivers to reduce their speed to navigate them safely. When a vehicle drives over a speed bump, it creates a jolt, which discourages speeding. This slows traffic in critical areas like parking lots, residential streets, and school zones to protect pedestrians and reduce the risk of accidents.

A: Yes, speed bumps can be used on private driveways to improve safety and reduce speeds. However, it is important to ensure that any speed bumps you install are compliant with local regulations and do not create any hazards or damage to vehicles.

A: Yes, speed bumps can be removed if necessary, although the process will depend on the type of speed bump and the surface it is installed on. Professional removal may be necessary for asphalt and concrete speed bumps, while rubber speed bumps can be removed using adhesive remover or other tools.
