Stainless steel pipe fittings can be classified into four types according to their connection method: socket type, threaded type, flanged type, and welded type. Socket type stainless steel pipe fittings are a reliable connection method, achieved by inserting the stainless steel pipe into the socket of the fitting and welding it.
Threaded type stainless steel pipe fittings achieve connection through the mating of internal and external threads, offering simple installation but relatively weaker sealing performance. Flanged type stainless steel pipe fittings are connected using flanges and bolts, suitable for applications requiring frequent disassembly and maintenance. Welded type stainless steel pipe fittings achieve a strong connection and good sealing performance through welding, but are more difficult to install.
