Chongqing polyethylene steel strip corrugated pipe wear-resistant steel strip pipeline

Chongqing polyethylene steel strip corrugated pipe wear-resistant steel strip pipelineProduct Introduction

Large diameter corrugated pipe sewage pipe, also known as buried drainage steel reinforced polyethylene (HDPE) spiral corrugated pipe, is a new type of plastic buried drainage pipe that has emerged in China in recent years. This product uses a continuous steel strip to press a spiral steel rib that is approximately ^ - shaped and wrapped between two layers of hot-melt polyethylene on the inside and outside, combining the high rigidity and strength of the steel with the flexibility, corrosion resistance, and wear resistance of polyethylene. diameter range300-3000Millimeters, length1-12Mi, which makes up for the limitation of the general ring stiffness of larger diameter plastic buried drainage pipes in the past, which can only reach SN8. This product can adopt multiple connection methods to meet different engineering needs, effectively meeting the requirements of sealing reliability and convenient connection construction.

2、 Spiral steel strip municipal pipeline steel strip pipe material characteristics:

1. Chemical resistance: not corroded by pollution, wastewater, or chemicals, and not corroded by decaying substances in the soil;

2. Impact resistance: The pipe wall adopts a 'U' - shaped structure, which is resistant to impact and pressure, and does not break even when the foundation sinks. Moreover, it has strong resilience after deformation and good adaptability to the foundation;

3. Aging resistance: The pipe is usually black and can withstand direct sunlight during storage and construction

Chongqing polyethylene steel strip corrugated pipe wear-resistant steel strip pipelinestoreMethod:

1. Short distance handling should not roll on hard, uneven or pebble surfaces to prevent damage to the protective or anti-corrosion layer.

2. All pipelines should be kept stable with appropriate gaps between them to prevent collisions.

3. Stacked transportation should not exceed a height of 4 times the pipe diameter or 2 meters. The contact area between the bottom of the vehicle and the pipeline should be flat and fixed to the transport vehicle with flexible straps or ropes to prevent rolling and collision. There should also be no sharp objects to prevent puncturing the pipe wall.

4. Nylon lifting straps are used for hoisting, and throwing or pulling pipes is prohibited. When disassembling the pipeline, the steel corrugated pipe should be placed on a square wood, which should be 600mm away from the pipe end. If the pipe is too low, 2-3 rows of square wood should be added in the middle of the steel corrugated pipe to prevent the pipe from bending.

Storage: When the steel corrugated pipe is placed outdoors, it should be covered with plastic film to avoid direct sunlight, and other supporting components should be stored indoors. The storage area for corrugated steel pipes should be kept away from the construction activity area.
