Product Description 

Transportation: Pipes are indispensable for the efficient, long-distance transportation of oil, gas, and related commodities. Our large-diameter transmission pipelines are pivotal in moving crude oil, natural gas, and refined products from production fields to refineries, processing facilities, and distribution hubs. This ensures an uninterrupted flow of energy and resources, enhancing operational efficiency.

Epoxy & Plastic Coated Anti-Corrosion Steel Pipe: Meticulously engineered to perform under diverse working conditions, these pipes can be tailored with various anticorrosive treatments. Perfect for buried installations, trenchless traction, pipe jacking, and open-air applications, the following anticorrosive solutions are available to cater to specific requirements:
- Buried: These pipes feature inner epoxy with outer PE, inner epoxy with outer 3PE, inner epoxy with outer 3PP, and inner & outer epoxy coatings, ensuring superior protection.
- Pipe Jacking: Designed with inner epoxy and outer 3PE, inner epoxy and outer 3PP, and inner epoxy with double-layer epoxy coatings, these pipes ensure optimal performance and durability.
- Trenchless Traction: Crafted for peak performance, these pipes include inner epoxy with outer 3PE, inner epoxy with outer 3PP, and inner epoxy with double-layer epoxy coatings.
- Open-Air Application: Constructed with inner epoxy and outer anti-UV coatings, these pipes are built to withstand environmental exposure and ensure longevity.

Inner Epoxy Resin Outer Polyethylene Coating Composite Steel Pipe: This specially pre-treated steel pipe boasts an inner surface coated with fusion-bonded epoxy powder and an outer surface coated with polyethylene powder. The result is a steel-plastic composite that offers exceptional corrosion resistance and outstanding performance in demanding environments.
