Stainless Steel Precision Tube Manufacturer in India

What is Stainless Steel Precision Tube?

Precision Tube is thin walled and available in both welded and seamless variants. They are also present in seamless thick wall variants. They are re-drawn in cold working conditions. The Stainless Steel Precision Tubes are usually delivered in random lengths between 5-8m or they are cut to give a fixed length. The tubing solutions are delivered with cold drawn, extremely polished, ground, or bright surface, depending on the size and thickness of the tube.

The Stainless Steel Precision Tube is used in a wide range of applications in manufacturing mechanical structures, auto parts, hydraulic equipment, and steel sleeves. They are also used in motor shells, hydraulic equipment, industrial processing machinery, electric gas pipeline, etc.

Difference Between Annealed and Hard Condition Precision Stainless Steel Tubing

The procedure is generally conducted in vacuum, air, or inert atmospheres. Annealing the Stainless Steel High Precision Tube softens it. But hard conditioning increases the work hardening rate. It means the tubes achieve a greater strength without losing their ductility.

Heavy Wall Stainless Steel Tubing vs Thin Wall Stainless Steel Tube

The Heavy Wall Stainless Steel Tubing solutions are those whose wall thickness is above 25mm. They are generally used for applications that involve greater volume and internal pressure within the pipe. The Thin Wall Stainless Steel Tube is a precision grade tube with multifunctional properties. They come with enhanced accuracy and tolerances.

One get Welding Thin Wall Stainless Steel Tubing- they are also available in seamless or redrawn cold worked conditions. The Ultra Thin Wall Stainless Steel Tubing solutions are also available which have a wall thickness to diameter ratio of less than 6%. The benefit of using Thin Wall SS Tubing is that it reduces the whole cost of the project substantially.

The Bending Thin Wall Stainless Tubing is very flexible in the way that they allow the machines to reduce the usage of welded contraptions and fittings. Also, the Large Diameter Thin Wall Stainless Steel Tubing has uniform hoop stress across its wall thickness. It is unlike the thick wall steel tubing that comes with variable hoop stress.
