he HYDRAULLIC TUBES are mainly used in High Pressure Hydraulic Lines, Fuel Injection Lines, Brake Lines etc. They are mainly used in Automotive Industry, Hydraulic Power Pack Manufacturing, Machinery Manufacturers, and Textile Machinery Manufacturers Etc.
Theses tubes can be manufactured in Straight Lengths in Random Length of 3 Meters to 6 Meters or fixed Length up to 12 Meters.
Our Seamless Tubes are manufactured by the Cold Drawn Process (Drawn on Mandrel) to provide the closest dimensional tolerance and smooth Outside and Inside Finish. Further to achieve the desired Mechanical properties the tubes are Heat Treated ( Normalized , Stress Relieved , Annealed , Tempered Etc ) as per the Customer / Grade requirement in Bright Annealing ( lnert Atmosphere ) Furnace . Bright Annealed tubes provide very desirable Ra Finish Values for The Inside Diameter Surface of the tubes. Straightening is done on Multiple Roll Straightening Machines 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.
We manufacture these hydraulic tubes as per various international standards such as :
|EN 10305 â€“ 1 E 215||EN 10305 â€“ 1 E 235|
|EN 10305 â€“ 1 E 355||DIN 2391 ST 35|
|DIN 2391 ST 45||DIN 2391 ST 30 AL|
The tubes supplied to the above grade can be supplied in various final delivery conditions like
|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|
