Yanhao Socket Weld Flanges are designed in accordance with industry standards (ISO 2861/1 and ANSI B16.5) and are manufactured from quality material. These ANSI B16.5 SW Flanges meet the requirements of various industries such as automotive, heavy engineering, railways, and pipeline engineering. Available in standard specifications, our range of flanges can also be customized according to our client’s requirements. As China leading Socket-Weld Flange Supply online, we strive to help you complete your projects as efficiently as possible with the highest quality products.

Socket Weld flanges’ widest range of application lies in pipes of small dimensions that conduct fluids at high pressures. ANSI B16.5 Socket Weld flange recommends its use in tubes up to 3 “in diameter in series 150, 300, 600, and up to 2 ½” in series 1500. In these SW flanges, the tube penetrates into the hub until it makes contact with the seat – Which has the same internal diameter as the tube- thus leaving a smooth duct without cavities. These flanges are frequently used in pipes intended for chemical processes, due to their particular characteristic of granting the duct a constant section.

What Is Socket Weld Flange?

Socket Weld Pipe Flanges are the flanges with the seat to weld are those in which the tube is inserted until it makes contact with the seat that has the same internal diameter as the tube, thus leaving a smooth conduit without cavities. The fixing of the flange to the tube is done by practicing a weld bead around the hub.

Socket Weld Flange is designed for small diameter and high-pressure applications provided that an internal and external double weld is made. It is similar to the weld-on flange when it comes to manufacturing, but has better fatigue resistance when installed with an internal weld. Unlike the press-in flange, abrasion of the internal weld to obtain a smooth appearance can be carried out without affecting the face of the flange, and therefore does not require subsequent surfacing. If only external welding is carried out, this flange must be reserved for low-pressure applications. It is not authorized beyond Class 1500 by standard B16.5.
