Polyurethane lined pipe

Polyurethane lined pipe adopts integrated molding design, ultra-high wear resistance, aging resistance, low friction coefficient, high pressure, lightweight design and convenient disassembly; It can realize the personalized design of product formula, effectively reduce the cost of pipeline maintenance and shutdown, and greatly improve the economic benefit.

Product overview

The steel lined polyurethane wear-resistant pipe developed and produced by ZOYO company is a new type of composite pipe lined polyurethane with steel pipe as the skeleton and polyurethane elastomer as the lining. It adopts a unique integral molding process, and the lining layer has no lap joint, and the steel pipe is 100% combined The wear resistance of the Polyurethane lined pipe developed by ZOYO is 25~30 times that of the steel pipe, and it also has excellent comprehensive properties such as high pressure corrosion resistance, low temperature resistance, aging resistance, oil resistance and organic solution resistance. It has multiple advantages of the traditional pipe such as steel pipe, rubber pipe, plastic pipe, ceramic pipe and so on

Notes:

1. The pipe connection method is flange connection or clamp connection.

2. Non-standard size pipes can be customized according to customer requirements.

Technical features

• Super wear resistance:

◇The wear resistance is 9.6 times that of UHMWPE

◇The wear resistance is 7.5 times that of natural rubber

◇The wear resistance is 25 to 30 times that of ordinary carbon steel

• The polyurethane lining adopts the pouring process and is formed in one go, avoiding local defects caused by the overlapping of the lining.

• Excellent corrosion resistance.

• Excellent aging resistance.

• Excellent low temperature resistance.

• Excellent water/oil resistance, no "swelling" or "cold wall effect" in water-based, oil-based media.

• Low friction coefficient (the PU surface as smooth as a mirror), small pipeline running resistance, greatly reducing the energy consumption of material transportation, the inner wall does not scale, to prevent the occurrence of long-term running scaling clogging accidents.

Fields of application

1、Metal and non-metallic mine process pipes and tailings conveying pipelines

2、Coal washing, coal preparation plant process pipelines and long-distance finished coal slurry transmission pipelines in the coal mining industry

3、Marine, port blowing and filling, dredging with mud discharge, sand drainage pipeline

4、Coal supply pipelines for thermal power plants, desulfurization process pipelines

5、Cement and other wear-resistant, anti-corrosion transport pipes
