The difference between HDPE double wall corrugated pipe and PVC double wall corrugated pipe

UPVC double-wall corrugated pipe, also known as PVC-U double-wall corrugated pipe, to polyethylene as raw material production and processing of the inner cavity smooth, surface wavy, inner and outer wall hollow special pipe fittings. The pipe fitting has beautiful appearance, distinctive structure, high strength, smooth inner cavity, small friction resistance, large supply, basically no concrete foundation, light weight, convenient transportation and assembly, and convenient engineering construction. Silicone ring hot melt connection mode is reliable, and the engineering quality is easy to ensure. Flexible interface. Strong anti-foundation settlement ability; The anti-leakage effect is obvious, and it can resist corrosion of various organic chemical media. The pipe does not accumulate scale, basically does not need to be transported, and the buried service life is over 50 years.

HDPE double wall corrugated pipe has certain advantages compared with other pipe fittings!

HDPE double wall corrugated pipe manufacturer characteristics: structure together, strength, compressive strength impact resistance. Smooth inner cavity, friction resistance, over flow. The docking is convenient, the connector has good sealing performance and no leakage. Lighter weight, convenient construction, reduce costs. Buried life of more than fifty years. High-pressure polyethylene belongs to the vacuum hydrocarbon polymer, the molecular structure is non-polar, corrosion-resistant. Raw materials for low-carbon environmental protection materials, non-toxic, no erosion, no fouling, can be recycled re-use. The available ambient temperature is wide, the pipeline does not break in the environment of -60 ℃, and the high temperature environment of the conveying medium Z is 60 ℃. The comprehensive engineering budget of cement and soil is very high at all, and the operating cost is low. No foundation is necessary when the soil layer is good.

HDPE double-wall corrugated pipe shall be made of HDPE (polyethylene plastic), extruded together by inner and outer extruders, molded at one time, with smooth inner cavity, serrated corrugated surface, and sandwiched hollow plastic pipe between inner and outer walls. Application field HDPE double-wall corrugated pipe is suitable for relatively high ambient temperature (60 ℃-20 ℃). With its common structure, the product has several advantages such as high ring steel, high strength, light quality, sound insulation, noise reduction and shock absorption, relatively high UV protection reliability, long service life, strong bending, compression resistance, high impact resistance, strong corrosion resistance, low temperature and high temperature resistance, etc. Sealing rubber rings are embedded in the valleys on both sides of the pipe, which has very good sealing performance, it can be paved in the section with weak geological environment, and the construction is convenient.

HDPE double-wall corrugated pipe has a better chemical resistance, anti-aging and resistance to natural environmental stress cracking performance. HDPE double-wall corrugated pipe, which is also traded out of raw materials, belongs to flexible pipe. Its main characteristics are as follows: the ability to resist compression, the surface is circular wavy structure, greatly improving the ring stiffness of the pipe fittings, thus improving the resistance of the pipeline soil environmental load, in such a characteristic level, HDPE double-wall corrugated pipe has certain advantages compared with other pipe fittings.
