The buried drainage is reinforced with steel bands
For you Product features
Underground drainage with steel belt reinforced polyethylene (PE) spiral corrugated pipe steel with enhancement send polyethylene (PE) spiral corrugated pipe is a kind of high density polyethylene (HDPE) as the matrix of inner and outer layer) and surface coating adhesive wall pipe winding structure.
Mainly used in municipal engineering sewage, wastewater and rainwater system; Sewage, waste water, rainwater system railway, highway and other drainage works in residential area. Industrial and mining enterprise waste water system; Gravity water system for agriculture, water conservancy and forestry irrigation.

Honors and qualifications
By three CengGou inner wall structure is a continuous layer of PE pipe, solid wall inner tube outer wrapping (using steel plate forming for "U" type) of the shape of corrugated steel reinforced belt, the corrugated steel belt reinforced composite in vitro with outer layer of polyethylene to composite with the spiral corrugated pipe of the whole.
The experimental test
1.Corrosion resistance long life.：
The steel strip surface is specially pretreated to increase the corrosion resistance of the steel and the adhesion of steel and plastic to improve the peeling strength. The whole structure of the tube is firm and reliable when the plastic material is fully melted.
2. Reliable performance：
The composite of each layer is carried out in the molten state of plastic, which is completely different from the secondary melting molding of the wound pipe (air wall tube). Therefore, it is completely sticky and strong at all levels.
3. Large diameter high strength.：
With u-shape with composite PE material, under the premise of the tubing without increasing the cost substantially improve the ring stiffness, same weight situations than winding pipe, carat strength greatly improved can solve the problem of overloaded etc, the ring stiffness keep in more than 8 kn/m, than cement pipe and other plastic pipe, lighter weight, higher strength.
The defects of ordinary steel tube are overcome, and the adhesion in long-term use is not attenuated. The coating thickness is not realized by other spraying process, which greatly improves the corrosion resistance and corrosion resistance of the steel pipe, the acid and alkali salt, the smooth friction coefficient of the inner and outer surface is small, and the water absorption rate is lower than (0.003%).
Confidence comes from quality and quality.
The company has built three manufacturing bases of steel belt reinforced polyethylene spiral corrugated pipe and MPP, PE pipe production area, hot dip plastic steel pipe and composite pipe production area and glass pipe production area. In terms of manufacturing concept, the company has always been adhering to the "quality first, satisfy the demand, attention to detail, keeping improving" the quality idea, the establishment of a strict quality assurance system in the process of production, the company has a leading domestic pipeline testing center, passed the ISO9001:2008, ISO14001:2004.
Do the company in line with, do strong, do big goal of pipeline industry, adhere to the tenet of "quality first, customer supreme", the high-quality goods production to meet customer needs is our basic work, bring tangible benefits for customers is our pursuit of the ultimate goal.
