Being the top producer of HDPE-lined fittings in Malaysia, we offer the latest anti-corrosion solution for oil & gas, mining, water treatment and chemical processing industries. Our cutting-edge HDPE lining technology improves the strength and chemical resistance of steel fittings so they can survive the most extreme operating conditions. Using proprietary processes such as high-pressure insertion and thermal forming, we form leak-proof, seal-free joints between the HDPE liner and the steel body. In different diameters and wall thicknesses, our fittings meet international standards and are up to 100 bar pressure-rated. With long-lasting performance, they have lower maintenance, longer lifespan and consistent flow in harsh environments.
HDPE-lined fittings are for use in water and corrosion resistance and chemical compatibility and long-term durability applications. Widespread in use in oil & gas, mining, water treatment, and chemical process industries, these products provide an inner barrier against aggressive gases, slurries, and corrosive fluids. These are best suited for systems subjected to reactive or abrasive materials extending the metal component’s lifespan without compromising structural integrity. HDPE-lined fittings are particularly suited to high-pressure applications, having a resistance to up to 100 bar. They offer a low-maintenance, dependable answer, providing consistent flow and leak-free performance, which reduces downtime in demanding industrial processes.

Designed to withstand high pressures, ensuring long-term performance in demanding environments
Highly resistant to chemical corrosion, providing longevity in aggressive environments
Compatible with fusion welding, mechanical coupling, and adhesive bonding for seamless integration
Requires minimal upkeep, leading to lower maintenance costs over time
HDPE-lined fittings are steel components coated with high-density polyethylene for enhanced chemical resistance, durability, and leak-proof performance.
HDPE lining provides excellent chemical resistance, low friction, and long-term durability. It protects the inner surface of the metal fitting from corrosion, scaling, and chemical attack—significantly extending service life in harsh environments.
Yes. The metal shell of the fitting provides structural strength and pressure rating, usually in line with standard piping classes (e.g., ANSI/ASME). The HDPE lining is designed to withstand internal pressure and thermal expansion without delaminating.
Yes, HDPE-lined fittings can be welded or repaired in the field using specialized techniques for seamless, durable joints.
We are the leading Manufacturer and Supplier of PTFE Lined Pipe, Fittings, Flanges, Spool and Valves in Malaysia.
