schedule 40 PVC pipe elbow

schedule 40 Polyvinyl chloride resin is used with stabilizers, lubricants and other combination after hot pressing extrusion molding, is the earliest development and application of plastic pipes. PVC-U pipes have strong corrosion resistance, easy adhesion, low price and hard texture. However, due to the leakage of PVC-U monomers and additives, they are only suitable for water supply systems with conveying temperatures not exceeding 45 degrees Celsius. Plastic pipes are used for drainage, waste water, chemicals, heating and cooling fluids, food, ultra-pure liquids, slurries, gases, compressed air and vacuum systems.


schedule 40 PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for about 2/3 of the market and soft PVC accounts for 1/3. Soft PVC is generally used in floors, ceilings and leather surface, but because soft PVC contains plasticizers (this is also the difference between soft PVC and hard PVC), poor physical properties (such as water pipes need to withstand a certain pressure, soft PVC is not suitable for use), so its use is limited. Hard PVC does not contain plasticizer, so it is easy to form, good physical properties, so it has great development and application value. Several additives, such as stabilizers, plasticizers and so on, must be added in the production process of PVC materials. If all the environmental protection additives are used, then PVC pipes are also non-toxic, odorless and environmentally friendly products.
