introduction

Our Alloy Steel Pipes are widely used for in Air conditioning and refrigerating systems. These pipes provide easy workability and can be bent an appropriate bending machine. The light ability to withstand high internal pressure makes our pipes ideal for most hot and cold water, central heating and gas services installations. These pipes can also be used for variety of other industrial applications. We are engaged in offering wide range of Pipes and Tubes in copper alloy pipes, nickel alloy pipes, stainless 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.

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 stainless steel under one roof viz. Dinesh Tube (India).
