Adhesive & Polyethylene Coating System

For Oil, Gas, Water Supply, Steel Pipe Is Generally Used In Such Highpressure Pipe Line System For Safety Reasons. For Protection Of Resources & Environment, Steel Pipes Should Be Anti-Corrosive With These Social Responsibilities In Mind, PE Coating Has Been Applied To The Surface Of Steel Pipes In Order To Maintain A Damagefree Surface During Transportation Installation, And Operation In Extremely High Or On Temperatures. PE Coating Is The Best Technology That Boosts The Value Of Steel To The Maximum.

Manufacturing Process
This Type Of Coating Is Applied By Spraying Epoxy Powder On
Preheated Pipes In Order To Quickly Cure The Epoxy.
And Them Applied By Polyethylene Extruding And Wrapping It
Around Medium And Large Diameter Pipes. (2" ~ 118")

A. The External Surface Is Shot-Blasted
    (SIS 05.59.00 Sa 21/2) Toremove Millscale And Rust,
    Obtaining Metal Surface Which Facilitates The Adhesion.
B. The Pipe Is Heated In A Gas Oven At A Controlled
     Temperature.
C. The Pipe Is Then Applied By Extruding.
D. The Adhesive Is Then Applied By Extruding.
E. Immediately Afterwards, The Extruded Polyethylene Is
     Coated Again On Top Of The Epoxy Coated Pipe.
F. After Application Of The Polyethylene, The Pipe Is Cooled By
    Air And Water.
Applications
Corrosion-Resistant Underground Pipelines For The Transport Of
Gas, Oil, Water, Etc.
Available Sizes
Outside Diameter : 4~118 In (100A~3000A)
