Hi-tech Metal & Tubes is a manufacturer and supplier of 5L X65 PSL2 and psl1 pipes in this specification. The 5L X65 Material contains added titanium which improves corrosion resistance, ductility and strength in the 5L X65 Pipes. The cost is higher compared to the lower grades of the same specifications but the application effectiveness is high. The X65 Carbon Steel has a minimum yield strength of 65Ksi and therefore it is suitable for high pressure piping. Our X65 Dsaw Pipes is used in different industries for the transmission of fluids over long distances. The strength is high in X65 Erw because of the electric resistance weld production. The Grade X65 PSL2 is one of the most commonly used product level specifications in the Grade X65q range of pipes. We offer our customers with X65m pipes of various nominal sizes. The welded as well as X65 Seamless Pipes of ours could be ordered according to the customer needs. We welcome your inquiries or custom orders.


API 5L Grade X65 PSL2 has the capacity to resist and stand up to hydrogen sulfide stress-related corrosion splitting, our buyers utilize the API 5L Grade X65 Pipe over the other steel grade pipes.
