HDPE double wall corrugated tube

Product introduction HDPE double wall corrugated pipe is used as main raw material of polyethylene resin as main raw material, adding appropriate auxiliary agent, which is suitable for building outdoor drainage and municipal sewage pipes.. It has the advantages of light weight, small drainage resistance, high compressive strength, corrosion resistance and easy construction, etc., and is the ideal material for replacing cast iron pipe and cement concrete pipe.. High density polyethylene (HDPE) has excellent chemical stability, aging resistance and environmental stress cracking resistance. The HDPE double wall corrugated tube made of raw material belongs to the flexible tube.. (two) product performance description Strong external pressure The outer wall of the annular corrugated structure, greatly enhancing the pipe ring stiffness, thus increasing the resistance of the pipe to soil load. In this performance, the HDP giant double wall corrugated pipe having obvious advantages compared with other pipes. Low cost of project Under the condition of equal load, the HDPE double wall corrugated tube can meet the requirement of thinner tube wall.. Therefore, with the same material specifications of the actual wall tube ratio, can save about half of the raw material, so HDPE double wall corrugated pipe cost is also low. This is another very prominent feature of the pipe. Construction convenience Because the HDPE double wall corrugated pipe is light weight, easy to handle and connecting, so the construction is quick and easy to maintain.. In the case of tight schedule and poor construction conditions, the advantages become more obvious.. Small friction coefficient, flow is large HDPE HDPE double wall corrugated pipe than the other tubes of the caliber can pass a greater flow. In other words, the same flow requirements, the HDPE can be used in a relatively small caliber double wall bellows. Low temperature impact resistance The embrittlement temperature of HDPE double wall corrugated tube is -70. At the ordinary low temperature condition (-30 above), there is no special protective measure, and the winter construction is convenient, and the HDPE double wall corrugated pipe has good impact resistance.. Good chemical stability Because of the polarity of the HDPE molecule, the chemical stability is excellent.. In addition to a few strong oxidants, most chemical media can not play a role in its destruction. General use of the environment of the soil, electricity, acid and alkali factors will not make the pipeline damage, do not breed bacteria, do not fouling, its distribution area will not increase with the running time to reduce Long service life Under the condition of no sunlight, the use of the double wall corrugated pipe of HDPE can reach 50 years.. Excellent wear resistance Germany has proved that the wear resistance of HDPE even higher than the steel pipe. Appropriate flex degree A certain length of HDPE Double wall corrugated pipe axial deflection, is not affected by the impact of the differential settlement of the ground can be without fittings on the direct shop in little & nbsp & nbsp; & nbsp; & nbsp; for straight groove and so on. (three) the main use of the HDPE double wall corrugated pipe Mainly used in the work under the pressure of the 0.6MPa following a large water delivery, water supply, drainage, sewage, exhaust, subway ventilation, mine ventilation, irrigation, etc.. (four) the merits of HDPE double wall corrugated pipe Reasonable structure appearance Temperature resistance -40 -60 Small resistance, flow Flame retardant &bull, long life Health performance reliability Comprehensive cost low • acid alkali resist High strength, strong seismic performance Energy saving and reducing consumption The installation transportation is convenient (five) service purpose and quality commitment The production of the purchase and sale contract signed by the parties is strictly enforced. To perform the exchange of goods by the contract (generally, within 24 hours after receipt of the delivery of the goods within the designated construction site). After the arrival, joint inspection sign, such as Ming The quality of the appearance can be returned to and without the qualified product.. Customer in strict accordance with the company issued by the product instructions in accordance with the requirements of the operation, I guarantee the company: the removal of man-made damage and irresistible natural disasters; I Division for 50 years, the use of 50 years, where damage occurred, the company is free of charge for your replacement. We shall take responsibility for the extension of the project or other losses caused by the quality of our party.. Customer complaints within 2-3 hours of reply within 24 hours of settlement. The company is responsible for the quality of the product.
