Connection Methods And Interface Types Of Stainless Steel Pipe Fittings

What are the connection methods and interface types of Stainless Steel Weld Fittings? There are many ways to connect stainless steel reducers. The common methods are compression, compression, union, push-on and socket welding, union flange connection, welding and traditional welding connection, welding and a derivative series of connection methods combining welding and traditional connection.

1. Threaded connection: Threaded connection is a common connection method for stainless steel pipes. Common threaded connection standards include common imperial threads (such as NPT, BSP) and domestic common metric threads (such as G, R). Threaded connection is suitable for some smaller pipe diameters and low-pressure applications.

2. Welded connection: Welding is a connection method with high fixedness and sealing, and is often used in large-diameter and high-pressure applications. Stainless steel pipe fittings can be connected by butt welding, butt welding, girth welding or arc welding.

3. Flange connection: Flange connection is a common and flexible connection method, suitable for occasions that require frequent disassembly and maintenance. By machining flange surfaces at both ends of the pipe fitting, the two flanges are connected into a connection with good sealing using bolts. Common types of stainless steel flanges include flat welding flanges, butt welding flanges, blind flanges, etc.

It is necessary to select the appropriate interface type according to the specific application requirements to ensure the sealing and reliability of the connection. At the same time, it is also necessary to comply with relevant pipeline specifications and standards to ensure that the design and installation meet the requirements.
