How is the building material, plastic pipe and sewer made? Where are the machines and how much is the selling price?
The raw materials for the general characteristics of production technology of pipe fittings and pipe the same general, China is now the popularization and application of plastic pipe of many varieties are: polyvinyl chloride (PVC) tube (in the form of the structure can be divided into: single tube solid wall pipe, reinforced radial pipe, core layer foam pipe, spiral pipe muffler double wall corrugated pipe, single wall corrugated pipe etc.), polyethylene (PE) pipe series products (according to the density and structure divided into HDPE, MDPE, LDPE double wall corrugated pipe, spiral wave fiber winding tube etc.) chloride PVC pipes, crosslinked polyethylene (PE-X) pipe, three type polypropylene (PP-R) pipe, polybutene (PB) pipe, ABS (three copolymer acrylonitrile butadiene styrene ethylene) (SP) pipe, aluminum-plastic composite pipe, high temperature resistant non crosslinked polyethylene (PE-RT), ultra high molecular weight polyethylene (UHMW-PE) pipe, polyethylene silicon core pipe and so on.

The plastic pipe used in different fields, they have a common characteristic is the need to withstand the pressure and impact, and in turn, the position, and sometimes need to add metal inserts, the tube wall is generally thicker, so when the injection molding production, attention must be paid to the quality of plastic plastic the temperature, pressure, and (especially the two pressure holding time long) control, speed, special machine Chun's existing UPVC, SPVC, PP-R and PE special screw, machine fittings special emission maximum (National injection amount of 43 kg, a clamping force of 2000 tons), to ensure the plasticizing quality of different plastics, in the room (such as Liansu, Gu and other companies) in the process of using well. Below to PP-R pipe production, for example, to explain the specific characteristics of the process: (1) PP-R raw material properties: raw materials generally do not need drying.
