Stainless steel pipe fittings
Stainless steel elbows are used where pipe fittings turn; flanges are used to connect pipes to each other and are connected to the pipe ends; stainless steel tees are used where three pipes come together; stainless steel four-way pipes are used where four pipes come together. Place; stainless steel reducer is used where two pipes of different diameters are connected.
Stainless steel flange
Stainless steel flange is a pipe connection used to connect pipelines, valves, pumps and other equipment. It is mainly composed of flange plates, sealing gaskets, flange bolts and other components. They are bolted together to form a sealed connection to prevent fluid leakage.
