Internal And External Epoxy/FBE Coated Steel Pipes

Product Overview

Using steel pipes as the base material, epoxy resin (EP/FBE) or polyethylene (PE) powder is firmly fused to the inner and outer surfaces of the steel pipe through processes such as electrostatic spraying and hot-dip plastic coating, forming a steel-plastic composite anti-corrosion pipeline.

Product Details

Product Advantages

Solvent-free and environmentally friendly : Zero VOC emissions during the curing process of powder fusion coating.

Strong corrosion resistance : Epoxy resin FBE resists cathodic disbondment, and is resistant to acids, alkalis, seawater, and microbial corrosion.

Internal and external synergy : The inner wall (FBE) prioritizes water quality protection and reduces friction; the outer wall (PE/3PE) provides long-term buried mechanical/electrochemical protection, achieving dedicated pipe design and internal/external division of labor.

Large-diameter one-piece forming : The base pipe of spiral welded pipe can be over 12m in length, with uniform wall thickness, and is suitable for deep overburden and high loads.

Flexible supply chain : compatibility can be achieved simply by changing the coating line, without significantly increasing manufacturing costs.

Application Areas

High-quality municipal drinking water and pure water delivery

Long-distance water diversion/main trunk line of water conservancy project

Medium and low pressure fire water system

Buried pipe sections crossing rivers/roads

Flexible Double Rubber Ring Socket Steel Pipe

Flexible double-rubber-ring socket steel pipe is a type of socket-connected steel pipe that uses a double-rubber-ring sealing structure. The pipe ends are equipped with a socket and a spigot, achieving a double seal through an insertion connection and relying on the two rubber sealing rings. This product adds a second sealing redundancy to the single-rubber-ring design, significantly improving the reliability and safety of the interface seal. The connection method is flexible socket-type, allowing for quick installation and making it particularly suitable for buried water supply pipeline projects. Applicable diameter: DN50~DN1800, working pressure ≤1.6MPa

Flame-retardant And Antistatic Coated Steel Pipes For Mining

Special plastic-coated steel pipes are specially developed for the special working conditions in underground coal mines. They use mining-grade polyethylene or epoxy resin coatings and achieve dual anti-static effects by uniformly adding antistatic agents and flame retardants: antistatic (eliminating static electricity accumulation that can ignite methane) and flame retardant (self-extinguishing when the flame is removed).

Internal And External Epoxy/FBE Coated Steel Pipes

Using steel pipes as the base material, epoxy resin (EP/FBE) or polyethylene (PE) powder is firmly fused to the inner and outer surfaces of the steel pipe through processes such as electrostatic spraying and hot-dip plastic coating, forming a steel-plastic composite anti-corrosion pipeline.

Stainless Steel Lined And Plastic-coated Composite Pipe

A novel bimetallic composite pipe is constructed by mechanically spinning a composite layer onto the inner wall of a regular steel pipe, lining it with a 0.3-1.5mm thick thin-walled stainless steel (304/316L) inner liner, and then coating the outer wall with an epoxy resin or polyethylene anti-corrosion layer. This structure is composed of two metals: an outer carbon steel layer provides mechanical strength and support, while an inner stainless steel layer ensures hygiene and corrosion resistance.

Heavy-duty Anti-corrosion Industrial/marine Plastic-coated Steel Pipes

Special anti-corrosion plastic-coated steel pipes are designed for harsh environments such as strong acids and alkalis (chemical industry), high salt spray and high humidity (marine engineering, seawater desalination). The inner wall is coated with a high-density epoxy FBE heavy-duty protective coating, which effectively resists the corrosion of carbon steel by seawater/chemical media; the outer wall is protected by an impact-resistant and highly impermeable polyethylene (PE/3PE) or fiberglass (FRP) outer sheath.

Plastic-coated Protective Sleeves For Power Cables

Plastic-coated steel pipes, specifically developed for direct-buried cable laying, generally employ hot-dip plastic coating processes (rotomolding, spraying, etc.) and incorporate epoxy resin/polyethylene coatings. As a rigid conduit, it can withstand significant external soil loads and damage to cables and pipes caused by vehicle dynamic loads .

Oil Casing (Oil Special Pipes)

Oil well casing is a core cementing string used in oil drilling and completion processes. It primarily supports the wellbore, isolates the formation, and ensures smooth drilling operations. The product is made of high-quality carbon steel using a seamless rolling process, manufactured strictly according to API SPEC 5CT standards. It is graded in multiple levels, from J55, K55, N80, L80 to P110, to meet the engineering needs of different well depths, pressures, and corrosive environments .
