WHY-01
Why corrosion protection
Hydrocarbons, water, CO₂, H₂S, and soil electrolytes attack carbon steel continuously. Protection is specified when remaining wall, inspection intervals, or failure consequence make bare steel unacceptable.

CONTROL SYSTEMS
Specified. Qualified. Installed.
Internal lining, external protection, and composite systems engineered for oil & gas and electricity infrastructure — documented to the standard of a controlled drawing package.

Engineering Basis
Why These Systems Exist
Corrosion is not a surface cosmetic issue. It is a progressive loss of wall thickness, pressure integrity, and service life. The systems below are selected to interrupt that mechanism — not to decorate assets.
WHY-02
Why pipe lining
Internal lining separates the process fluid from the host pipe. Geometry of the steel remains; the chemical exposure path is blocked. Preferable when replacement diameter, route, or land rights make new pipe impractical.
WHY-03
Why GRE
Glass-reinforced epoxy provides a continuous, high-chemical-resistance barrier with controlled thickness and mechanical interlock (C-ring). Selected where sour service, water injection, or long inspection cycles demand a durable liner system — typically to API 15CLT practice.
WHY-04
Why RTP
Reinforced thermoplastic pipe is chosen for corrosion-immune flowlines within its pressure/temperature envelope — reducing steel corrosion risk where spoolable or composite construction fits the hydraulic design.
