introduction

We are engaged in offering wide range of Pipes and Tubes in copper alloy pipes, nickel alloy pipes, Duplex steel pipes, stainless steel duplex pipes, copper & alloy steel and nickel & copper alloy material. These are widely used in ship building, aircraft & aerospace, drilling & well building industries. Our range like copper alloy pipes, nickel alloy pipes, stainless steel pipes, stainless steel duplex pipes available in various grades and specifications to suit the requirements of clients. Stainless steel Duplex pipes & tubes feature excellent flow characteristic with higher strength and better stress corrosion cracking resistance.Thereby, our Duplex Steel UNS S31083 Pipes have a high strength and impact toughness, combined with the superior abilities to resist pitting and crevice corrosion. Positive Material Identification is done on all raw material procured at Dinesh Tube(India). These Stainless steel pipes can be employed for high temperature and pressure applications. We can offer these pipes in different dimensional specifications based upon the requirements of the clients. Our stainless steel and duplex pipes can be easily welded to the system for a leak proof joint.

As importers, exporter, dealers & stockiest with huge stocks Dinesh Tube (India) become within one of the most reliable sources for quality within a short span. We are registered with the best of semi-govt., govt., private & multinational companies. Our aim is to provide our buyers with everything in Duplex steel under one roof viz. Dinesh Tube (India).
