Pre-Insulated, Clad & Coated Pipe

Engineered pipe systems for district cooling, corrosive service and buried pipelines. Pre-insulated pipe-in-pipe (EN 253), CRA/Inconel-625 clad and lined pipe, cement-mortar lined water pipe, and 3LPE/3LPP/FBE external coatings.

Coated and pre-insulated steel pipe
/ Overview

Insulated, clad & coated systems

Beyond bare pipe, many GCC projects need engineered systems. AAM Steel supplies pre-insulated pipe (PUF/PU foam core with HDPE or GI/spiral outer jacket) to EN 253 / EN 15632 for district cooling and hot-fluid transfer, with bonded pipe-in-pipe, leak-detection wires and matching pre-insulated fittings and valves.

For corrosive and abrasive service we supply CRA clad / bimetallic pipe (carbon backing clad with stainless or Inconel 625), cement-mortar-lined (CML) water pipe (AWWA C205), rubber/PE/FBE-lined pipe, and external anti-corrosion coatings — 3LPE, 3LPP, FBE, coal-tar, PU and tape wrap.

/ FAQ

Common questions

What is pre-insulated pipe?
A bonded pipe-in-pipe system — a carrier pipe surrounded by PU foam insulation and an outer HDPE (or GI/spiral) jacket, to EN 253 — used for district cooling/heating with optional leak-detection wires.
What is clad or lined pipe?
Carbon-steel pipe internally clad or lined with a corrosion-resistant alloy (e.g. stainless or Inconel 625) to combine carbon-steel strength with CRA corrosion resistance at lower cost than solid alloy.
What external coatings do you supply?
3LPE, 3LPP, FBE, internal epoxy, cement-mortar lining (AWWA C205), coal-tar, PU and tape-wrap — selected by soil, temperature and service.
Where can I buy pre-insulated / coated pipe in the GCC?
