Polyethylene (PE) trenchless drainage pipe

Category: Drainage and sewage pipe

Description：Polyethylene (PE) non-excavation drainage pipes are primarily made from PE100 grade pipe material, with necessary additives added, and are formed through extrusion processing using a single-screw extruder. This product is resistant to compression, acids, alkalis, and chemical corrosion. It uses heat fusion connections, with the tensile strength of the welded joints greater than that of the body strength, and has good toughness. It is suitable for non-excavation dragging construction of rainwater and sewage collection, treatment, and discharge pipeline systems. Excavation pipes are also primarily made from PE100 grade pipe material, with necessary additives added, and are formed through extrusion processing using a single-screw extruder. This product is resistant to compression, acids, alkalis, and chemical corrosion. It uses heat fusion connections, with the tensile strength of the welded joints greater than that of the body strength, and has good toughness. It is suitable for non-excavation dragging construction of rainwater and sewage collection, treatment, and discharge pipeline systems.

Description

　　Product Introduction

The polyethylene (PE) non-excavation drainage pipe is mainly made of PE100 grade pipe material, with necessary additives added, and is formed by extrusion processing using a single-screw extruder. This product is pressure-resistant, acid-resistant, alkali-resistant, and resistant to chemical corrosion. It uses hot melt connection, with the tensile strength of the weld joint greater than that of the body strength, good toughness, and is suitable for non-excavation dragging construction of rainwater and sewage collection, treatment, and discharge pipeline systems. The excavated pipe material is mainly made of PE100 grade pipe material, with necessary additives added, and is formed by extrusion processing using a single-screw extruder. This product is pressure-resistant, acid-resistant, alkali-resistant, and resistant to chemical corrosion. It uses hot melt connection, with the tensile strength of the weld joint greater than that of the body strength, good toughness, and is suitable for non-excavation dragging construction of rainwater and sewage collection, treatment, and discharge pipeline systems.

　　Product Features

1. The pipe has high ring stiffness and high tensile strength between the pipes; under complex working conditions of non-excavation construction, the pipes are not easily broken or crushed.

2. During non-excavation construction, surface damage to the pipes is difficult to avoid; the ability of the pipes to resist slow crack growth will be greatly reduced, minimizing the harm caused by surface damage to the functional use of the pipes.

3. The pipes use hot melt connections made from the same material, ensuring safety and reliability without any 'running, leaking, dripping' phenomena.

4. The pipes have good corrosion resistance and toughness, solving the defects of traditional steel pipes that are prone to corrosion, have a short service life, are difficult to construct, and have poor resistance to uneven foundation settlement.

　　Application Fields

Suitable for non-excavation dragging construction of rainwater and sewage collection, treatment, and discharge pipeline systems.

Urban water supply, water supply network renovation, agricultural irrigation pipelines.

Industrial raw material transportation, sand mining, slurry transportation.
