Stainless Steel Pipe Fittings
What are stainless steel pipe fittings?
Stainless steel pipe fittings belong to a kind of pipe fittings. They are made of stainless steel so they are called stainless steel pipe fittings. They include: stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel caps, etc. Main stainless steel material: 304, 304L, 316, 316L
classfication:
Depending on the product type, they include:
1)stainless steel elbows: Stainless steel elbows are used where pipe fittings turn;
2)stainless steel tees: Stainless steel pipe tee are used where three pipes are collected;
3)stainless steel crosses: stainless steel pipe cross are used for four pipes Place;
4)stainless steel reducers: The stainless steel reducer is used where two pipes of different diameters are connected;
5)stainless steel caps.
Depending on the connection method,they include:
1) socket weld ss pipe fittings
2)threaded ss pipe fittings
3) flanged ss pipe fittings
4)welded ss pipe fittings.
