Stainless steel pipe fittings have high requirements on the quality of the pipe material and have higher requirements on the outer diameter ovality, wall thickness, and physical function of the rubber ring of the drainage cast iron pipe. Due to the poor watertight performance of the flat joint, in addition to strictly controlling the pipe material In addition to the body quality of pipe fittings, etc., high-pressure flanges should pay special attention to the port maintenance of pipes and pipe fittings, and the ovality and flatness of the butt welding elbows to ensure the port. During the construction of the device, the operation procedure should be strictly followed. Stamping elbows, especially in the case of straight pipe installations, need to use a riser clamp at the joint of each pipe to fix the riser on the load-bearing wall of the building; a hanger should be added at each interface of the horizontal pipe to connect sanitary utensils. In the relatively concentrated toilet and bathroom, if the distance between the two interfaces on the horizontal branch pipe connecting the sanitary ware is not more than 600mm, a hanger can be set in the center.
Seamless stainless steel pipe fittings are long strips of steel with hollow sections and no joints around them. The thicker the wall thickness of seamless stainless steel pipe fittings, the more economical and usable it is, and the thinner the wall thickness, the higher the processing cost. The pipe fitting has a hollow section, which is a kind of pipeline for conveying fluid, and a pipeline for conveying certain solid substances of natural gas, oil, gas, and water. Compared with solid steel such as round steel, seamless stainless steel pipe fittings are lighter in weight when the bending and torsional strength is the same. It is economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as some building construction roofs. steel scaffolding, bicycle racks, automobile transmission shafts, oil drill pipes, etc.
