Oil And Gas Pipe 3 Layer PE Coated Anticorrosive Steel Pipe
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.
Product Name: 3LPE Coated Pipe, 3PE Coating Pipe, Anti Corrosion Steel Pipe
Coating Type: 3 Layer Polyethylene
OD: 25 mm to 3000 mm
WT: SCH5S to SCH160, XXS
Length: Up to 12m
Connection: Weld And Thread
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.
