PTFE Lined Pipe is one of India’s most reliable producers of HDPE-lined fittings, providing superior anti-corrosion solutions. For oil & gas, mining, water treatment and chemical processing industries. We increase the strength and durability of steel fittings by internally lining them with HDPE. Which renders them extremely chemical and harsh environment resistant. With special processes such as high-pressure insertion and thermal forming, we provide a leak-proof, strong bond between the HDPE lining and steel body. Available in different wall thicknesses and diameters, our fittings adhere to international standards of quality and can withstand up to 100 bar pressure. With long-term performance in mind, our HDPE-lined fittings provide low maintenance, long service life and consistent flow in harsh conditions.
HDPE-lined fittings are best wherever corrosion resistance, chemical protection, and longevity are a priority. Commonly applied in oil & gas, mining, chemical plants, and water treatment plants, they form a safe barrier within pipelines to deal with aggressive fluids, slurries, and corrosive gases. HDPE-lined fittings serve to increase pipeline life by shielding the metal structure, particularly in high-pressure systems up to 100 bar. They also provide leak-proof operation, stable flow, and reduced downtime, making a cost-effective solution for demanding industrial processes.
