Buried polyethylene (PE) steel belt reinforced spiral corrugated pipe

Category: Drainage and sewage pipe

Description：Steel belt reinforced polyethylene (PE) spiral corrugated pipes are made from high-density polyethylene as the primary raw material, with a wave-shaped steel belt coated with adhesive resin as the main supporting structure. The polyethylene material is wound to form an integrated spiral corrugated pipe. In addition to having the corrosion resistance, smooth inner wall, and low flow resistance typical of ordinary plastic pipes, the product features a hollow annular structure reinforced with a steel skeleton, allowing it to meet ring stiffness requirements of SN8, SN10, SN12.5, and SN16.

Description

　　Product Introduction

Steel belt reinforced polyethylene (PE) spiral corrugated pipe is made from high-density polyethylene as the base material, with a wave-shaped steel belt coated with adhesive resin as the main supporting structure, and wrapped with polyethylene material to form an integrated spiral corrugated pipe. In addition to the corrosion resistance, smooth inner wall, and low flow resistance typical of ordinary plastic pipes, the product can meet ring stiffness requirements such as SN8, SN10, SN12.5, and SN16 due to its hollow annular structure reinforced with a steel skeleton.

　　Product Features

1. Pressure resistance and impact resistance: The pipe is reinforced with a steel belt, achieving standard ring stiffness. It has good strength and impact resistance, making it suitable for any foundation.

Adaptability;

2. Economic efficiency: Lower cost compared to other plastic pipes of the same specification, lightweight, saving transportation and construction costs, and easy management and maintenance;

3. Chemical resistance: It will not be corroded by sewage, wastewater, or chemical agents, nor will it be damaged by decaying substances in the soil or plant roots;

4. Aging resistance: The pipe is generally black and can withstand direct sunlight during stacking and construction;

5. Excellent wear resistance: More wear-resistant than steel pipes, cast iron pipes, and cement pipes;

6. Superior drainage flow performance: The inner wall of the pipe has low flow resistance, fast drainage speed, strong water flow capacity, and large flow volume.

　　Application Fields

1. Municipal engineering: Used for municipal underground drainage, sewage discharge, rainwater collection, water transportation, ventilation, etc.;

2. Electrical and telecommunications engineering: Serves as protective pipes for power cables, optical cables, and communication signal cables;

3. Industry: Used for irrigation in farmland, orchards, tea gardens, and forest belts; can also be used for rural water supply and irrigation pipes.

Note: 1. The length of the pipe is generally 6m/each, 9m/each, 10m/each, or 12m/each; it can also be agreed upon in the contract between both parties. The length of the pipe should not have a negative deviation exceeding one-half of the pitch. 2. The product is divided into socket sealed rubber ring connection, heat shrinkable tape wrapped connection, and electric heat fusion socket connection.
