Plastic-Coated Steel Pipes
Using steel pipe as the base material, with a plastic coating on the inner or outer wall, it combines the high strength of steel pipe with the corrosion resistance of plastic.
Steel-Plastic Lined Composite Pipe
The outer layer of the steel pipe ensures structural strength, while the inner plastic lining (such as PE or PPR) provides corrosion-resistant and hygienic transport performance.
3-Layer Polyethylene（3PE）Coated Pipe
The three-layer structure of epoxy powder, adhesive, and polyethylene provides corrosion resistance, impact resistance, and wear resistance, making it suitable for long-distance transportation of oil, gas, chemical, and other media.
Stainless Steel Pipe
Made entirely of stainless steel, it boasts excellent corrosion resistance, high-temperature resistance, and oxidation resistance, with a smooth and easy-to-clean surface.

our workshop
Plastic-Coated Steel Pipe Workshop
This plastic-coated steel pipe workshop handles pipes from 2 to 48 inches in diameter by applying a fused plastic coating via advanced processes like electrostatic spraying and immersion coating. We provide complete solutions for the entire production line—from pre-treatment and coating to curing, inspection, and finishing—ensuring medium-to-high output of pipes with uniform coating, strong adhesion, and precise tolerances for reliable corrosion protection.

Plastic-Lined Steel Pipe Workshop
This plastic-lined steel pipe workshop specializes in lining pipes from 2 to 48 inches in diameter by inserting and bonding a seamless thermoplastic liner to the internal surface. Utilizing key processes like rotational molding (rotolining) and pull-in (swage-lining), we supply integrated solutions for the complete production sequence—including pipe preparation, liner forming, bonding, testing, and finishing. Our production ensures medium-to-high volume output of pipes with a uniform, void-free liner, excellent chemical resistance, and reliable adherence to dimensional standards for demanding fluid transport applications.

Stainless Steel -lined Pipes
This workshop specializes in the production of stainless steel-lined pipes, handling diameters from 2 to 48 inches. The core process focuses on the precise mechanical bonding of a corrosion-resistant stainless steel liner inside a host pipe. Utilizing the hydraulic expansion technique as the key technology, we provide complete solutions for the entire production sequence—including precision machining of components, liner insertion, controlled hydraulic expansion for bonding, end finishing, and final testing. Our line ensures medium-to-high volume output of hybrid pipe systems that reliably combine the structural strength of the outer pipe with the superior corrosion, abrasion, and contamination resistance of the internal stainless steel liner, designed for demanding service in oil & gas, chemical, and high-purity applications.

3PE Coating Workshop
This 3PE (Three-Layer Polyethylene) coating workshop specializes in applying high-performance external anti-corrosion coatings to large-diameter steel pipes, typically from 16 inches and above. The process involves the sequential application of a three-layer system: a fusion-bonded epoxy (FBE) primer for corrosion protection, a copolymer adhesive layer for bonding, and an outer layer of polyethylene (PE) for mechanical and environmental protection. Our integrated production line provides a complete solution encompassing pipe surface preparation (blast cleaning and heating), precise multi-layer coating application, curing, and final inspection. This ensures medium-to-high volume output of pipes with exceptional, long-term corrosion resistance, mechanical durability, and reliability for demanding cross-country and subsea pipeline applications.
