从China供应商批发进口3pe Anti Corrosive Pipeline — FOB条款

This 3PE anti-corrosive pipeline uses a three-layer polyethylene coating system applied over carbon steel API 5L Grade X42 to X80 base material, delivering long-term protection against soil stress, moisture and chemical exposure in buried or submerged applications. The coating consists of an epoxy primer, a copolymer adhesive and a high-density polyethylene top layer, with the combined system meeting API 5L and ISO 3183 standards for oil, gas and water transmission lines. The pipe is engineered for infrastructure projects where durability and minimal maintenance are critical over decades of service life.

Carbon steel substrates in grades X42 through X80 provide the structural strength, while the 3PE coating adds corrosion resistance and abrasion protection typical for pipelines in aggressive soils or marine environments. The coating thickness typically ranges from 2.0 to 3.5 mm depending on the nominal pipe size, with the epoxy layer providing adhesion and cathodic protection, the adhesive layer ensuring bond integrity under thermal cycling, and the PE layer offering UV and mechanical damage resistance. Standard outer diameters span from 219 mm to 1420 mm, with wall thicknesses aligned to API 5L specifications for the selected grade.

These pipelines are primarily used in oil and gas transmission networks, municipal water supply systems and industrial fluid conveyance, where resistance to external corrosion is non-negotiable. Buyers typically include EPC contractors, utility providers and infrastructure developers sourcing bulk quantities for large-scale projects. The product is supplied in 6 to 12 metre lengths with beveled ends for welding, and can be customized for specific project requirements such as additional coating layers or specialized joint protection systems.

Hebei Tongmao Pipeline Equipment Manufacturing Co., Ltd is based in Cangzhou, Hebei Province, China, where it specializes in the production of anti-corrosive pipelines for industrial and infrastructure applications. The company operates from Pusheng Road in Cangzhou, a region recognized for its concentration of pipeline and steel fabrication facilities, and holds a harbor trust tier indicative of verified export capabilities and compliance with international shipping standards.

The supplier’s profile confirms its focus on 3PE and FBE coated pipelines, with no additional unverified claims about production capacity, certifications, or client history. The absence of a recorded response rate or average response hours indicates that direct communication metrics are either not publicly tracked or not applicable, and buyers are advised to confirm these details through direct inquiry. The company’s specialization in anti-corrosive solutions for carbon steel pipelines is the primary differentiator in its product offerings.
