THE MECHANICAL TUBES are available for use like HYDRAULLIC CYLINDER TUBE (READY To HONE TUBES), MECHANICAL SUPPORE TUBES, GENERAL ENGINEERING TUBES and are generally used in industries like Hydraulic Cylinder Manufacturers, Automotive Component Manufacturers, Shock Absorber Manufacturers, Textile Machinery Manufacturers, and Defense etc. These tubes find application in industries which require high strength along with high accuracy of the Inside/Outside Diameter of the tube. The surface finish also plays a very critical role in the application.
These Mechanical Tubes can be manufactured in Straight Lengths of Random Length cut or in Fixed Length. Our Seamless Tubes, designed for the utmost precision, are manufactured using the Cold Drawn Process (Drawn on Mandrel). This process guarantees the closest dimensional tolerance and a smooth Outside and Inside Finish. To achieve the desired Mechanical Properties, the Mechanical Tubes undergo Heat Treatment (Normalized, Stress Relieved, Annealed, and Tempered, etc) as per Customer/Grade requirements. Our production process ensures that the strict Inside/Outside diameter requirements of the industry are met; we manufacture these Mechanical Tubes only using Tungsten Carbide Dies and Tungsten Carbide Mandrels.
Straightness is maintained as per the code requirements on a Multiple Roll Straightening Machine to achieve accuracy up 1mm: 1000mm Straightness. Our stringent Quality checks and Best Packing practices (For Exports Special 4 Layer Packing) ensure that the material delivered to the customer is of the highest quality and reaches the destination in best condition.
The Mechanical Tubes are supplied with such finish and accuracy that they can be directly taken up for the honing operation.
The tubes supplied to the above grade can be supplied in various final delivery conditions like
| DESIGNATION | SYMBOL | DESCRIPTION |
|---|---|---|
| COLD DRAWN / HARD | +C | NO FINAL HEAT TREATMENT AFTER THE FINAL COLD DRAWING PROCESS |
| COLD DRAWN / SOFT | +LC | AFTER THE FINAL HEAT TREATMENT THERE IS A SUITABLE DRAWING PROCESS |
| COLD DRAWN AND STRESS RELIEVED | +SR | AFTER THE FINAL COLD DRAWING PROCESS THERE IS STRESS RELIEF HEAT TREATMENT |
| ANNEALED | +A | AFTER THE FINAL COLD DRAWING THE TUBES ARE ANNEALED |
| NORMALIZED | +N | AFTER THE FINAL COLD DRAWING OPERTAION THE TUBES ARE NORMALIZED |
We can manufacture straight lengths up to 15.00 Meters with maximum outside diameter of 150mm and maximum thickness up to 12.7mm.
