MM PTFE Lining is a world-class manufacturer of HDPE Lined Fittings, headquartered proudly in Riyadh, Saudi Arabia. Dedicated to providing quality and innovative products, the company focuses on manufacturing an assortment of HDPE lined components suitable for withstanding corrosion and abrasion in adverse industrial conditions. The product lines offered by them consist of HDPE lined elbows, tees, reducers, flanges, crosses, as well as specialized fittings custom-built for special requirements. These fittings are extensively applied in chemical processing, water treatment, mining, and oil & gas industries with high durability, resistance to leakage, and long service life under harsh service conditions.
HDPE lined fittings are metallic pipe fittings lined internally with High-Density Polyethylene (HDPE) for increased resistance to corrosion, abrasion, and chemical attack. The double-structure integrates the pressure-bearing capacity and tensile strength of steel with the protective, non-reactive nature of HDPE. Employed chiefly in aggressive fluid conveying systems, HDPE lined fittings assist in prolonging equipment life, decreasing maintenance expenditures, and providing a secure, leak-free operation in a range of 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
They are resistant to chemicals well, have a longer service life, and require less maintenance than unlined metal fittings.
HDPE Lined Fittings are commonly used in industries like chemical processing, water treatment, oil & gas, and petrochemicals, where resistance to harsh chemicals and corrosion is crucial.
Regular inspections for signs of wear and tear are recommended, along with cleaning to remove any buildup of debris. HDPE lined fittings generally require minimal maintenance.
The metal portion can be welded using standard practices, but care must be taken not to damage the HDPE liner. Field repairs of the liner itself are limited and usually require specialized tools or returning the item to the manufacturer.
We are the leading Manufacturer and Supplier of PTFE Lined Pipe, Fittings, Flanges, Spool and Valves in Huston, USA.
