The material of groove fittings is ductile iron, which has the advantages of good sealing, high tensile strength, high yield strength, good corrosion resistance and oxidation resistance, smooth casting surface, good mechanical properties, and strong stability. The application of groove fitting connection technology makes complex pipeline connection processes simple, fast, and convenient. It is widely used in pipeline engineering such as fire protection, petroleum, drinking water supply and drainage, water conservancy, municipal construction, mechanical equipment, and air conditioning.
Using welded pipe as the base pipe, the molten metal zinc reacts with the iron matrix to
produce an alloy layer, thereby combining the straight seam welded pipe and the coating
Galvanized square tube is a term for square and rectangular pipes, which refers to steel
pipes with equal or unequal edge lengths at the pipe mouth. Galvanized square tube is made by rolling steel
strip through processing
Angle iron, I-beam, galvanized flat iron and other profiles are coated with zinc to prevent
corrosion. It can be finished steel or used for the return and rolling of welded pipes
Galvanized pipe fittings are made of malleable cast iron, which has the advantages of good
toughness, good thickness, accurate angle, full, smooth and precise threads, and long threads
