  The threaded flange can not be stored for a long time. It should be checked regularly. The surface of the surface must be kept clean, clean and clean. It is kept in a clean and dry place. It is strictly forbidden to pile up or store it in the open air. The ball valves, globe valves and gate valves of the threaded flange are only fully opened or fully closed when they are used. They are not allowed to adjust the flow rate so as to avoid erosion of the sealing surface and accelerate wear. Threaded flange are easy to be made, simple in manufacture, low in cost, and widely used; but the rigidity is poor, so it can not be used in chemical piping systems with demand, flammable, explosive and high vacuum. The seal face type has plane and surface. The ASME B16.36 Class 600 Stainless Steel Threaded flange structure is simple, small, light weight, tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastic and sealed. It is also widely used in the vacuum system. It is convenient to maintain, the ball valve structure is simple, the sealing ring is generally active, and the disassembly and replacement are convenient; the ball and the ball are fully opened or closed. The sealing surface of the seat is isolated from the medium.
