The information for coated and insulated steel pipe products

Hebei Haihao Group can produce the 3LPE pipes and fittings,FBE and epoxy painted pipes and fittings, PU pre-insulated pipes and fittings, cement lining pipes Etc.

What does Piping Costing mean?

Piping products coating is one of the most reliable corrosion prevention methods in industry application.This coating provides a constant protective layer to prevent the pipes from the corrosion damage,which is a cost effective and viable solution to maintain the integrity.The coating contain the pipe internal coating(pipe lining) and pipe external coating.

What’s the advantage of the coating to piping products?

The coating can improve the flow capacity of gas or liquid.Coated pipework dries faster than uncoated pipe,which means the inspection and commissioning can be faster and easier on the line.

Pipings that are internally coated could create a vast difference in lowering the costs of compression and pumping over the pipe’s lifespan.

What’s the coating process for the piping products?

Before the coating,we do the blast cleaning process to the pipes or fittings,the preparation is an important factor in coating works ,we should pay more attention to the cleaning process to make sure the highest standard quality.

Our main coating methods:Fusion Bonded Epoxy Coating System;Three-Layer Coating Systems: Polyethylene and Polypropylene;Internal cement mortar lining.

 Fusion Bonded Epoxy Coating System

 Three-Layer Coating Systems

 Internal cement mortar lining

The Fusion Bonded Epoxy (FBE) coating system is an externally-applied thermosetting resin for pipe. The three-layer pipe external anti-corrosion system consists of a layer of high-performance Fusion Bonded Epoxy onto which a co-polymer adhesive layer is extruded, followed by a layer of extruded polyethylene or polypropylene until the desired thickness is obtained. It is performed by use of a spinning machine, which rotates the pipe centrifugally causing the cement mortar to equalize and form a smooth, dense protective lining.

Haihao Group provides pipes with different coating solutions in compliance with the most rigorous international standards for both onshore and offshore oil and gas projects.
