Large Diameter Pipe production line, pipe production line, Hengda Mastery

HDPE (High Density Polyethylene) double-wall winding large diameter pipes to HDPE as raw material, forming twice, it has the following advantages: 1, chemical stability, acid, alkali, salt and strong resistance, sewage, waste and chemicals The corrosion resistance of the soil to rot corrosion, no rust. 2, impact resistance, pressure, wall-shaped structure with a unique elastic deformation and difficult to destroy, have a very good base for any applicability. 3, anti-aging, pipe storage and can withstand the brunt of the construction process hdpe large diameter pipe production lines of the sun, in the pipe design and production process fully into account the 50 years when the material attenuation factor. 4, wide temperature range, can be used within a temperature range of -50C to 60C, not the cracking and swelling leakage. 5, light weight, large-caliber hollow-wall HDPE pipe production line, the weight of the cement tube 1/10 (water equivalent Efficiency) without heavy construction equipment. 6, easy to connect. 7, superior wear resistance pipe production line manufacturers, than cement pipes, steel wear life more than 50 years. 8, the price of raw materials, low construction, management and maintenance costs. 9, HDPE material is non-toxic, harmless to land, the use of renewable, environment-friendly green products Pipe is produced using the heat-setting process pipe production line, generally divided once finalized and secondary processing of two kinds of stereotypes. A setting process: Nylon or plastic granular material by heating plastic extruder plastics extruded into a thin sheet strips, long strips from the die for extrusion without water cooling that is wound onto the winding machine with different specifications clamping mandrel , and then after cooling water from the cooling setting mandrel that is shaped into a spiral jacket. Secondary molding process: Nylon or plastic particles through the extruder strip after entering the cooling water; long cooled and then the winding machine with different specifications wound onto the mandrel; the mandrel is then pushed into the autoclave heat curing. After a certain time in the tank, from the mandrel can be formed. Large Diameter Pipe production line, pipe production line, accessible by Qingdao Hengda Hengda Tongda Machinery Co., Ltd.
