pvc tubes offer sea Widex (certified), pvc pipe

PVC pipe connections are mainly gasket, bonding and flanged three kinds. Greater than or equal to 100 mm diameter pipes commonly used Aprons interfaces; less than 100 mm diameter pipes are commonly used adhesive joints, and some loose-fitting. When crossing sewer pipes or other pipes, metal pipes are normally used, then the plastic pipe and metal pipe flange connection. Before and after the valve is connected to the pipe flange connection are also used. When a small-diameter pipeline by solvent bonding, shall socket at the back of small rounded to form a groove, and to ensure smooth and perpendicular to the axis of the fracture, so as to bond securely to prevent leakage. 2 generally greater than or equal to 100 mm diameter PVC pipes are used Aprons interfaces. Must arrange before installing the tube socket parts chamfering, also check if the quality apron. You must wipe socket, apron, etc. When installing clean. 3 traditional pipeline trench excavation requires only able to install the pipe into the trench and can be sealed can, in the absence of the original loose soil, compaction can not pressurized cushion. pvc material processing a pigment in certain metal ions will lead to PVC resin thermal oxidative decomposition. Determination method pigmented polyethylene was heated to 180 ℃ when the change of hue. Since the pigment contained in the metal ions to promote accelerated decomposition of PVC, resulting in change of hue. Meanwhile, note that the same added lake red PVC can produce different color, such as those containing calcium, the color difference is small; manganese is large color difference, which is due to the manganese metal promoter PVC dehydrochlorination due. Sulfide-based colorant (such as cadmium red, yellow, etc.) used in PVC coloring, coloring agents may be due to the decomposition of hydrogen sulfide release. Such colorants should not be mixed with lead stabilizers in order to avoid generating the black lead sulfide. 2, PVC insulation on electrical influence pigment as cable materials like PVC and polyethylene pvc pipe processing, electrical properties should be considered after coloring. Especially for its own PVC insulation resistance than polyethylene is poor, so the impact is even greater pigment. Instructions, select inorganic pigments organic pigments for coloring PVC relatively good PVC is the growth rate of 4% of the production and application worldwide for its electrical insulation. PVC growth in Southeast Asia is particularly significant, thanks to the Southeast Asian countries have carried out urgent infrastructure needs. In the three-dimensional surface film can produce the material in the material properties of ABS (acrylonitrile - butadiene - styrene copolymer) ABS is a professional pvc pipe used to transport drinking water, mud and chemicals. The most commonly used DWV (drain waste exhaust) applications. Unplasticized polyvinyl chloride (UPVC) and CPVC (chlorinated polyvinyl chloride after) having the entire operating temperature range within UPVC excellent chemical resistance pvc pipe with a wide range of operating pressure belt. Due to the nature of long-term high-intensity, stiffness and cost-effectiveness, UPVC systems account for a large proportion of the plastic pipe installation. CPVC is resistant to many acids, bases, salts, paraffins, halogen and alcohols. This is not an anti-solvent, aromatic hydrocarbons and some chlorinated hydrocarbons. PP (polypropylene) Polypropylene is suitable for use in the food supply pvc pipe, drinking water and ultra pure waters, as well as in the pharmaceutical, chemical and other industries. PE (polyethylene) polyethylene has been used successfully for many years drinking water and wastewater, hazardous waste, and safe transportation of compressed gas. pvc tubes offer sea Widex (certified), pvc pipe provided by Qingdao Rubber Material Co., Widex.
