Stainless steel pipe fittings include stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel pipe caps, etc. According to the connection method, the fittings can be divided into four types: stainless steel socket weld fittings, stainless steel threaded fittings, stainless steel flanged fittings and stainless steel weld fittings. The stainless steel elbow is used between two lengths of pipe to allow a change of direction. A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. The stainless steel tee is used to connect three lengths of pipe. The stainless steel cross is used in the place where four pipes converge. A stainless steel reducer is used for connecting two pipes with different diameters.
Main stainless steel materials: 304, 304L, 316, 316L.
Manufacturing standards: GB/T 12459, GB/T 13401, ASME B16.9, SH 3408, SH 3409, HG/T 21635, DL/T 695, SY/T 0510, DIN 2605.
Classification
1. Stainless steel socket weld fittings
The stainless steel socket weld fitting is attached by inserting the stainless steel pipe into the socket of the pipe fitting and then making argon arc welding along the edge of the pipe fitting. It is the most reliable of all connection methods.
The inner diameter of the fitting socket is equal to the outer diameter of pipes.
2. Stainless steel butt weld fittings
The outer diameter of the fitting socket is equal to the outer diameter of the pipe.
Butt welding is generally used for stainless steel piping systems with a large size.
3. Stainless steel press fittings
Stainless steel press fittings feature reliable and safe connection, convenient and fast construction, maintenance-free and relatively low cost. And they are suitable to be pit mounted.
The working principle of stainless steel press fittings is to insert thin-walled stainless steel pipes into the socket of the fittings, and use the special pressing tool to press the stainless steel pipe in the pipe fitting. The cross-section shape of the pressing portion is hexagonal, and there is an O-ring between the stainless steel pipe and the press fitting, which makes this fitting have the characteristics of anti-leakage, anti-drawing, anti-vibration and high pressure resistance. Therefore, the stainless steel press fitting is an advanced attachment in the drinking water system, the water supply system, the heating system, the steam system, the oil and gas piping system.
