ASTM A105 Carbon Steel Flanges is a mechanical product that serves the purpose of joining pipes together. It may be in the shape of a welding neck where it is welded to the collar flange or threaded and then where it is screwed to the flange. Other methods include using a lap joint to make connections using a stub end, a socket weld, or a slip-on.
The ASTM A105 Carbon Steel Flange specification can include different grades of stainless steel material made of flanges. The flanges of ASTM A105 Carbon Steel are the products that sustain well in high-temperature services. These sorts of flanges are mostly useful in applications like chemical industries and other applications. High corrosion resistance and durability power are available.
Here are 5 tips for using a steel pipe flange for the first time:
- Use Slip-on Flanges in low-pressure services:
Users more prefer slip-on flanges due to its affordability, quick & easy installations. ASTM A105 Carbon Steel Flanges used for non-critical low-pressure services like cooling water, firewater, and other non-challenging pipework due to its strength being 1/3 lower than that of the welded neck flange.
- Socket Weld Flanges in high-pressure piping system:
During high-pressure piping works below 2 inches (DN50), socket weld flanges are more preferred. Good welding experience is essential to make this connection since a radiographic examination of the fillet weld is not easily executable.
- Lap Joint Flanges for high-cost material pipelines:
Lap joint connections are the most suitable for pipelines in high-cost materials, such as nickel alloys and stainless steel. It significantly reduces the total cost or any of the flanged connections that are required. The lap joint relation established is by combining the end of the stub. It is then processed for welding to join the pipe, and the lapped flange or back flange.
- Use of weld neck flanges to a butt weld pipe for better performance:
Tapered hub on the weld-neck flanges with an end that’s butt weld can connect to a butt weld pipe. For the quality determination of the weld, one can use radiography, ultrasound, or visual method. The welded connection of a pipe and a weld neck flange features good fatigue and mechanical stress performance.
- Take the support of a skilled professional executes pipe flange joints:
Qualified personnel should be the one who executes flange connections to limit any hazardous leakages from happening in the pipeline. As steel pipe flanges are useful for the first time, a properly trained engineer should be the one to execute the flanged joints.
