Refrahold Industries Pvt Ltd, has its own 100% automated Tube mill- A STATE OF THE ART infrastructure with qualified operators

In Refractory industry, Pipe/Tube is manufactured from a wide range of metal grades (SS304, SS316, SS310, Inconel (600, 601, 800HT), Carbon Steel and more..), by a variety of processes such as welding or casting.

Pipe has long been standardized for dimensions and by industry-type; pipe for residential construction falls under different codes than pipe used in power or chemical plants, where the materials may be subject to high-pressure process fluids. Piping design is an engineering specialty unto itself, encompassing many aspects of mechanical engineering from welding processes to corrosion control, from sizing pressure drops to addressing seismic loading.

The most important dimensions for a pipe or tube is the outer diameter (OD) together with the wall thickness (WT). OD minus 2 times WT (SCHEDULE) determine the inside diameter (ID) of a pipe, which determines the liquid capacity of the pipe.

The mechanical parameters for pipes are the pressure rating, the yield strength, and the ductility.

The standard combinations of pipe Nominal Pipe Size and Wall Thickness (schedule) are covered by the ASME B36.10 and ASME B36.19 specifications (respectively, carbon and alloy pipes, and stainless-steel pipes).

We are known for our precision and experience in pipe manufacturing.
