Coating Machinery Systems for Steel Pipe Anticorrosion Line

Coating Machinery Systems for Steel Pipe Anticorrosion Line

With over many years design and processing experience, and on the base of import advanced technology from abroad and our customer’s suggestion, we have developed Steel pipe inner coating production line.

This line mainly applies to coating industries and construction work with water, air, oil transportation system and air discharging system.

This line suitable for steel pipe inner wall anti-drag type and antisepsis type coating, also include many kinds of liquid coating such as solvent-free epoxy coating.

Three-layer PE/FBE coating is the most popular method for isolation and corrosion protection of oil-gas transportation pipelines .using fusion bond epoxy powder coating with multi layer of thermoplastic polymers offer the most strong protection properties for ground/underground pipe lines with maximum isolation and minimum moisture absorption.

Min. steel pipe diameter Φ79mm, Max. Steel pipe diameter Φ2540mm.

Easy operation and maintain convenient, high productivity and stable coating.

The line mainly include: steel pipe heating system/ steel pipe inner wall derusting system/ steel pipe inner wall dedusting system/ steel pipe inner wall coating system/steel pipe transportation system/ cured coating system/ hydraulic & pneumatic system/system and electric control system.

Process description

1- raw pipe inter to the line by crane or lift truck
2- pipe pass through pre heating unit (IF unit or heating oven)
3- after heat up , pipe pass through shot blast unit to clean the surface
4- pipe heat up by secondary IF unit and heat up to right temperature
5- FBE powder coating will be applied on heated pipe
6- co-polymer adhesive will be apply on pipe surface after few secound
7 thermoplastic layer will be apply immediately after co polymer
8- coated pipe pass through cool water shower to cool down
9- coating will be inspected visually and electronically
10- edge trimming
11- final inspection, marking , storage
