ERA Piping Systems, PVC Pipe Fitting ,Type II,FLANGE COUPLING ,US Ⅱ 014Socket x BSPT, CE Specification: System: Installation requires the use of primer and solvent cement. For pressure applications, sharply angled pressure fittings must be used. Polyvinyl chloride (PVC) is one of the most...nPVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for floors, ceilings and the surface of leather. However, because soft PVC contains plasticizers (this is also the difference between soft PVC and hard PVC), its physical properties are poor (for example, water pipes need to withstand a certain water pressure, and soft PVC is not suitable for use), so its scope of use is limited. Rigid PVC does not contain plasticizers, so it is easy to shape and has good physical properties, so it has great development and application value. During the production process of PVC materials, several additives are bound to be added, such as stabilizers, plasticizers, etc. If all environmentally friendly additives are used, then PVC pipes will also be non-toxic, odorless and environmentally friendly products.
