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! Prestressed plastic corrugated pipe is a new material into the hole, compared with prestressed corrugated metal pipe, it has the following advantages: 1, pre-stressed plastic corrugated pipe for continuous extrusion, sealing, no leakage of plasma leakage phenomenon. 2, prestressed corrugated plastic pipe materials for hdpe, acid corrosion, anti-aging, never rust. 3, prestressed plastic corrugated pipe with steel cable friction coefficient of only 0.14, which can effectively reduce the tension in the process of prestressing friction losses. 4, prestressed plastic bellows flexible, high ring stiffness, is not afraid to step on the pressure, can not easily be broken tamper chisel. 5, prestressed plastic corrugated pipe is not conductive, can prevent stray current corrosion. 6, prestressed corrugated plastic pipe bending degree, easy connection, can greatly improve the efficiency of construction. National key project roads and bridges, railway bridges, building water conservancy, electric power: the use of field
