ASME B16.5 Carbon Steel Socket Weld Flanges SWRF Class 600 for Industrial Applications
Introduction:
Shaanxi Peter International Trade Co., Ltd. is a reputable manufacturer of high-quality ASME industrial Socket weld flanges in China. We provide prompt delivery programs for standard-sized carbon steel socket weld flanges. Additionally, we can supply socket weld flanges made from special carbon steel grades. Our Socket weld flange dimensions adhere to ASME B16.5 standards, which encompass sizes ranging from NPS ½" to 24".
At Shaanxi Peter International Trade Co., Ltd., we prioritize customer satisfaction and strive to provide exceptional products and services. Our dedicated team is committed to meeting the diverse needs of our clients by offering reliable and durable socket weld flanges that consistently meet industry standards.
Description of ASME B16.5 Socket Weld Flanges:
Socket weld flanges are commonly used for smaller-sized high-pressure pipes and find extensive application in high-pressure systems such as hydraulic equipment and steam lines. These flanges have a counter-bored bore that accommodates the pipe, providing a smooth bore for improved fluid or gas flow. They are connected to the pipe by inserting the pipe into the socket end and then applying a fillet weld around the flange's hub.
At our manufacturing facility, we produce Raised Face socket weld flanges and Flat Face Socket weld Flanges to cater to companies from various industries, including power generation, petrochemical plants, pharmaceutical plants, shipbuilding, oil refineries, wastewater treatment plants, paper mills, and turnkey projects.
To ensure proper installation, a 1/16" (2.0 mm) gap should be maintained between the pipe end and the bottom of the flange socket to account for differential thermal expansion. This prevents weld cracking that may occur due to temperature differences. In high-stress situations, an internal weld can be added for additional strength. The internal weld is then ground smooth to minimize turbulence and flow restriction.
Socket weld flanges conforming to ASME B16.5 standards are permitted under the B31 series of Pressure Piping Codes and ASME Boiler and Pressure Vessel Codes. Although these flanges are available in sizes up to 3", they are most commonly used in sizes of 2" and smaller, making them suitable for small diameter high-pressure piping systems. However, it's important to note that socket welding is susceptible to crevice corrosion. Corrosive solutions from the process fluid can accumulate in the gaps and crevices between the pipe's outer surface and the socket surface of the flange, leading to potential crevice corrosion. Therefore, socket weld flanges are typically avoided in corrosive applications.
