Stainless steel pipe fittings with flat mouth connection to the quality of pipe, the external diameter of the cast iron pipe oval, wall thickness and the physical function of rubber ring has a higher demand, as a result of the watertight function of the poor, as a result, in addition to strict control pipe and pipe fittings, such as the quality of the high pressure flange to pay special attention to pipe and pipe fittings of the port maintenance, welding elbow to ensure that the ellipse and flatness of the port. In the installation of construction should be strictly in accordance with the operation procedure. The punching elbow is specially in the straight pipe device when each root pipe interface requires a riser to fasten the riser to the load-bearing wall of the construction. Cross-tube at each interface should be added to the hanger, in the convergence of sanitary appliances more concentrated in the bathroom, if the horizontal branch of the two interface between the sanitary ware is not less than 600mm, can be set up in the center of a hanger.
Seamless stainless steel pipe is a hollow section with no seams around the long steel. The thicker the wall thickness of seamless stainless steel pipe fittings, the more economical and the combination, the wall thickness, the processing cost will increase greatly. Pipe fittings have a hollow section, is a kind of flow of the pipeline, the natural gas, oil, gas, water machine some solid material pipeline. And round steel, such as solid steel, seamless stainless pipe fittings in flexural and torsional strength, the lighter weight, is an economic cross-section of steel, is widely used in the manufacture of structural parts and mechanical parts, such as some construction of steel scaffolding, bicycle racks, automotive transmission shafts, oil drill pipe
