Contact: 15933187015 QQ2867376454 Hengshui City Value Optical Engineering Rubber Co., the predecessor of Taocheng scale light Rubber Products Factory, the company specializes in the production of a bridge with a prestressed corrugated plastic pipe, prestressed corrugated metal pipe, ultrasonic test tube (Acoustic tube), anchor bolts embedded corrugated tube, pipe, flat tube, rubber ...... specification is complete quality assurance! The company has passed ISO9001: 2000 international quality system certification, the products are widely used in bridges, roads, concrete works! Corrugated plastic pipe bending method prescribed after repeated bending of five dedicated plug able to pass, the flexibility from a qualified plastic corrugated plastic wave tube. ? Plastic bellows cryogenic vacuum drop hammer impact test the impact of the rate of TIR maximum allowable value of 10%. ? Connect plastic bellows? Take a long plastic corrugated plastic pipe welding machine can weld or use of mechanical connections. Mechanical connection in the form of contacts were examined, including the pipe and the pipe connecting the connection pipe connecting the head pipe and connected to the anchor plate, three types of the exhaust pipe and pipe connector connected to the exhaust pipe. ? Prestressed plastic corrugated pipe is flexible, high ring stiffness, is not afraid to step on the pressure, can not easily be broken tamper chisel? Prestressed plastic corrugated pipe is made of high density polyethylene (? HDPE?) By molding plastic extruder Single wall corrugated pipe for post-tensioned concrete structure, as the tendon duct into the hole. I produced the appearance of quality prestressed corrugated plastic pipe products, structure, size, ring stiffness, local lateral loads, flexibility and other technical indicators, in line with the Ministry of Transportation industry standard "prestressed concrete bridge with plastic bellows" JT / T529-2004 Technical requirements and GB / T9647-2003 national standards.
