Oil And Gas Pipe 3 Layer PE Coated Anticorrosive Steel Pipe

Ordinary bare pipes corrode in harsh environments, reducing their service life and making them costly to construct and maintain. However, due to the good performance of each layer of 3PE coating system, 3PE coated pipeline can protect the pipeline in harsh environment and extend its service life to 30-50 years or even longer.

Product Introduction

3PE coated pipes Description

 

3PE coated pipes significantly reduce the construction and maintenance costs of pipelines. At the same time, 3PE coated pipeline has good thermal insulation performance, the heat loss is only 25% of the traditional pipeline, which saves a lot of energy costs during operation. Finally, 3PE coated pipeline can be directly laid in the ground or water, or even directly laid in the frozen soil without the need to build a trench due to its good anti-corrosion performance and low-temperature impact resistance.

Standard: ANSI, JIS, DIN, EN, ISO,DIN;CAN/CSA,NFA

 

Advantages

  • ‌Extremely long service life‌

The three-layer structure works together to block soil moisture, microorganisms and chemical media, and the pipeline life is increased to 30-50 years, which is more than 3 times longer than traditional anti-corrosion technology‌.

  • ‌Excellent mechanical protection performance‌

The impact strength is more than 15 joules (traditional anti-corrosion pipes are about 11 joules), which can resist the collision of construction machinery and foundation settlement stress‌.
The pressure bearing capacity of the spiral welded pipe matrix (such as SSAW) reaches X70-X80 steel grade, which is suitable for high-pressure transmission environment‌.

  • ‌Adaptability to harsh environments‌

Passing -40℃ low temperature shock and 60℃ high temperature tests, it maintains stability in complex geology such as deserts, wetlands, and seabeds‌.
