DIN 1629 ST 52 Honed Cylinder Pipe and ST52 Boiler Tube supplier in India

ST52 Tube

ST52 Tube

Manufacturers and distributors of ST52 Tube in India

The ST52 Tube is steel made up of low-carbon manganese. It is readily weldable and comes with good impact resistance. This includes environments that have a sub-zero temperature. The ST52 Steel Tube is primarily used in conditions that are untreated or normalized. These are mechanically quite similar to the mild steel pipes. The ST52 Tube is mainly used in welded components in general engineering and construction.

We are one of the biggest manufacturers of DIN 2391 ST52 in India. Our products are known for their high quality and superior finishing. Clients can get the specified tubes in different sizes, according to their requirements. We offer full customization of our products. Our products get exported to different parts of the world.

We have a massive stock of ST52 Honed Cylinder Tube in various size ranges and thicknesses, ideal for use in Oil and Gas Pipelines. These are also used in the low-pressure conveyance of gas and transportation of oil, air steam, water, and several other fluids. The ST52 Pipe can be described as a cost-effective solution for machinery, irrigation, and building constructions.

The ST52 Boiler Tube is efficiently used in areas involving high heat or extremely cold or hot gases. The ST52 Seamless Precision Steel Tubes is one of the best solutions for high-temperature services applications. They are reliable and very cost-effective too.

We are one of the top distributors of ST52 tubes in India. We also supply our products to various parts of the world. Clients can get faster supply and doorstep deliveries according to their requirements.
