Gaskets are generally divided into non-metallic gaskets and metal gaskets, large diameter stainless steel flange can be stacked with two pieces of PTFE to bring entanglement, because the flange in welding and processing will sometimes have deformation, flange winding can be used to adjust, if used in the air pipeline also to be entangled, otherwise it will affect the tightness. Some use asbestos rubber gaskets, but now less and fewer people choose to use asbestos rubber gasket, mainly because asbestos is harmful to the people who use and contact, therefore, it is recommended that you install PTFE.
Three-way pipe fittings are usually used in construction, power, shipbuilding, chemical industry, the different types of three-way pipe fittings have their own shortcomings and advantages, to distinguish their respective characteristics and deficiencies, you can better use tee pipe. Three links in the pipeline are mechanical tee, Groove reducer tee, Groove machine tee, ordinary tee. The different diameter tee is divided into two kinds: Groove type, Threaded type: Groove type is used to 3 clamp, thread type is another 2 clamp. Mechanical three-way two types: groove, thread type. Groove Type to use 1 additional clamp, threaded type does not need. The common tee is divided into two kinds: Groove type and thread type. Groove to use 3 additional clamp, threaded the other as long as 2 of the clamp. The mechanical tee is the kind with the clamp and the need to open the hole in the steel pipe. Threaded Reducer Tee is the small pipe is the thread, and the supervisor is still the clamp type.
