Epoxy Coated Steel Pipe

1. Introduction

Epoxy Coated/Lined Pipe (Liquid Epoxy & Lining)

Focus:Flow efficiency, potable water safety, and versatile protection.

Introduction:Our Epoxy Coated Pipe solutions offer versatile protection for both internal and external surfaces. We specialize in Internal Epoxy Lining according to API RP 5L2 and AWWA C210, designed to reduce friction and increase hydraulic flow efficiency in gas and water transmission lines. For the water industry, we offer certified food-grade epoxy linings that prevent scale buildup and maintain water quality. Whether for industrial chemical transport or municipal water supply, our epoxy solutions provide a cost-effective, smooth, and highly resistant finish that protects your asset from the inside out.

Internal Lining:Reduces pumping costs by providing an ultra-smooth internal surface.

External Protection:Excellent resistance to hydrocarbons, acids, and alkalis.

2. Epoxy Coated Steel Pipe Applications

Epoxy coated steel pipe is commonly used for buried oil and gas pipelines, water transmission lines, sewage systems, fire water pipelines, industrial fluid transport and corrosion-control projects. Buyers should confirm whether the coating is required on the internal surface, external surface or both, because liquid epoxy lining, internal epoxy coating and external epoxy coating may have different thickness, curing, holiday test and inspection requirements.

3. Standards and Coating Requirements

For quotation, the inquiry should state the base pipe standard, steel grade, pipe size, wall thickness, epoxy coating or lining type, coating thickness, surface preparation grade, holiday test requirement, cutback length, repair rule and required inspection documents. Common project references may include API RP 5L2, AWWA C210, CSA Z245.20, AS 3862 or owner-specific coating specifications.

4. Epoxy Coated Steel Pipe Inspection and Shipment Protection

Before shipment, Forever Steel can provide mill test certificates, coating thickness checks, visual inspection, holiday test records, packing photos and third-party inspection support when required. For export orders, end protection, lifting control and stable packing are important to reduce coating scratches during inland transport and sea shipment.

Epoxy Coating and Lining Process for Steel Pipes

Frequently Asked Questions

1. How do you control lining or coating quality on epoxy coated steel pipe orders?

We implement internal quality control from raw material review to final shipment release. For orders related to drinking water pipelines, fire water systems, and industrial fluid transport, buyers usually expect the product to match both the application and the supporting epoxy coated steel pipe, epoxy resin lining, and internal epoxy pipe systems requirements.

2. Can you provide MTC and inspection records for epoxy coated pipe supply?

Yes. We can provide Mill Test Certificates according to EN 10204 3.1, and 3.2 can be arranged when required. Third-party inspection by agencies such as SGS, BV, or ABS can also be accepted before shipment.

3. How is epoxy coated pipe protected during sea shipment to avoid scratches or lining damage?

We use export-oriented packing and loading methods based on the product type, including end protection, stable bundling or blocking, waterproof wrapping where needed, and careful loading control. The goal is to reduce rust, scratches, bevel damage, face damage, coating damage, thread damage, or handling impact during domestic transport and long sea shipment.

4. Is epoxy coated steel pipe commonly used for drinking water and fire water systems?

This product is commonly supplied for drinking water pipelines, fire water systems, and industrial fluid transport, with buyer demand often tied to epoxy coated steel pipe, epoxy resin lining, and internal epoxy pipe systems.
