What is the general interface of stainless steel large and small heads?

Stainless steel reducer, also known as large and small heads, is one of the chemical pipe fittings and is used to connect two different pipe diameters.What is the general interface of stainless steel large and small heads? The interface of stainless steel large and small heads is generally achieved through threaded connections, welding or flange connections, depending on the needs and design of the piping system.

1. Threaded connection: Threaded connection is a common stainless steel pipe connection method. Common thread connection standards include common inch threads (such as NPT, BSP) and domestically common metric threads (such as G, R), etc. Threaded connections are suitable for some smaller pipe diameters and low pressure applications.

2. Welding connection: Welding is a connection method with high fixation and sealing, 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 processing flange surfaces on both ends of the pipe fitting, and using bolts to connect the two flanges into a better-sealed connection. Common stainless steel flange types include flat welding flanges, butt welding flanges, blind flanges, etc.

It is necessary to select the appropriate interface type according to 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 codes and standards to ensure that the design and installation meet the requirements.
