Anti-corrosion ERW Steel Pipe

Anti-corrosion steel pipes are used in petroleum, chemical, gas, heat, sewage treatment, water, bridges, steel pipes and other engineering fields, they are divided into the following categories.

3LPE Coated ERW Steel Pipe

Three layer polyethylene anticorrosion is one of the main technical system of buried pipeline corrosion protection domestic and abroad. It has good corrosion resistance, low water absorption and high mechanical strength. It has been used widely in the field of buried water conveyance, gas transmission and pipeline transportation in recent years.

GB/T23257-2009 technical standard for polyethylene anticorrosion coating for buried steel pipeline

SY/T0413-2002 technical standard for polyethylene corrosion resisting layer of buried steel pipeline

DIN30670-2012 technical standards for polyethylene coatings for steel tubes and fittings in Germany

CAN/CSA-Z245.21-M92 Canadian technical standard for polyethylene pipe anticorrosive coating on outer wall

Use: products are widely used in oil pipelines, natural gas pipelines, heating pipes, water pipelines.

3PP (Polypropylene) Coated ERW Steel Pipe

DIN30678 standard technical specification for polypropylene coating for steel pipe and pipe fittings

3PP Coating Advantages:

The 3PP coated steel pipe refers to steel tubing with three layers of PP(Polypropylene) coating. It offers high electric strength, acid resistance, alkali resistance, salt-tolerance, electric insulation, long service life, thermal endurance and impact resistance. Because of advanced steel pipe coating technology, this type of plastic coated steel pipe features well-bonded coatings.

3PP Coating Applications:

The 3PP coating steel pipe is suitable for transferring special materials, such as high temperature materials, because it offers high electric strength, acid resistance, alkali resistance, salt-tolerance, electric insulation, long service life, thermal endurance and is impact resistant.

FBE Coated ERW Steel Pipe

FBE coating pipe is Fusion Bonded Epoxy coating steel pipe. It is an externally applied heat resin for pipe. With a form of dry powder at thickness 300-600 microns on to the heated surface of pipe. Once the FBE coated on the pipe surface, the FBE film provides an extremely hard surface with great adhesion to the pipe surface. The FBE layer in a even form and have good resistance to the chemical reaction.

Advantage of the FBE coating pipe:

(1) Convenient to spraying, no pollution, excellent resistance for high temperature (-40°C to 85°C)

(2) High strength and anti-bending performances;

(3) Strong adhesion, good integrity, anti soil stress and wear.

FBE coated steel pipe usually buried in soil and under water between -40°C~85°C temperature.

On the other hand, the defect of the FBE pipe is it doesn’t have good resistance to mechanical performances and humid conditions.

Our FBE coating perform the standards as per SY/T0315, CAN/CSA Z245.20, AWWA C213, Q/CNPC38 etc.

Use: Widely used in land, underwater pipeline anticorrosion.

Polyurethane Insulation Coating ERW Steel Pipe

The polyurethane direct buried heat preservation pipe is a direct buried preheating heat preservation pipe with good heat preservation performance, safety and reliability, and low engineering cost. The buried thermal insulation pipe not only has the advanced technology and practical performance that is difficult to compare with the traditional trench and overhead laying pipeline, but also has obvious social and economic benefits, and is also a powerful measure for heating and energy saving.

It is characterized by a multi-purpose use to prevent the spread of fire and good fire safety performance. Black jacket insulation pipe includes spiral steel pipe, straight seam steel pipe and seamless steel pipe. The outer layer is made of black polyethylene and is called a black jacket insulation tube.
