Subsea Pipeline Linings Solutions

High-Pressure Resins for Internal Pipeline Protection

Protecting the arteries of global energy. Our pipeline resins provide a glass-smooth, chemically inert internal barrier that prevents corrosion and improves flow efficiency.

Industry Challenges

Critical barriers in
subsea pipeline linings processing.

01
Presence of hydrogen sulfide (crude oil souring)
02
High-pressure gas permeation (Explosive Decompression)
03
Erosion from sand and particulates at high flow
04
Temperature gradients through the pipe wall
