Many of these flanges were the first-generation high-vacuum flanges developed for the commercial market. Two flanges of the same diameter (one with oring) are bolted together to create a leak-tight connection.
The advantage of Socket Weld Flanges is their ease of installation. Connecting a tube to a socket weld flange is simple. The tube end is inserted into the flange’s socket. Once aligned, a fillet weld is performed around the ID, creating the connection. This straightforward process saves time, making O-ring Socket Weld Flanges a popular choice for many applications.
O-ring Socket Weld Flanges effectively connect tubes and take up less space than weld neck flanges. We offer a variety of sizes, types, and specifications to best suit your application
