API5L X52 PSL1 6 Inch SCH40 Plastic Coated Steel Pipe DIN 30678
Product Description
These plastic coated steel pipes are manufactured in strict compliance with API5L Grade X52 PSL1 and DIN 30678 standards, with a nominal size of 6 inches and a wall thickness specification of SCH40. Adopting high-quality carbon steel as the base material, they undergo professional plastic coating treatment (epoxy or polyethylene) to form a dense, smooth and wear-resistant protective layer on the inner and outer surfaces.
The API5L X52 PSL1 grade ensures excellent mechanical properties, including high tensile strength, good toughness and strong pressure-bearing capacity, fully meeting the requirements of medium-pressure pipeline transmission. The SCH40 wall thickness design balances structural strength and cost-effectiveness, suitable for long-distance and heavy-duty pipeline applications. The plastic coating layer provides superior anti-corrosion, anti-rust and anti-scratch performance, effectively isolating the steel pipe from corrosive media such as moisture, chemicals and soil, greatly extending the service life of the pipeline.
Designed with precise dimensional accuracy and smooth inner wall, these pipes reduce fluid flow resistance and ensure stable medium transmission. They are widely used in oil and gas transmission, water supply and drainage systems, chemical engineering, municipal engineering, and industrial pipeline projects. The combination of API5L and DIN 30678 standards ensures good interchangeability and compatibility with international pipeline equipment. With easy installation, low maintenance cost and reliable performance, they are a cost-effective solution for harsh and long-term pipeline operation scenarios.
