Manufacturing Process
- Seamless Pipes are cut to the specified length as per requirement. The end portion of the pipe is pre-heated to make the shape of cylinder bottom by spinning, using a natural gas and liquid oxygen. It is then cleaned from inside to remove any residue or debris.
- The same Process is followed to form the cylinder top.
- To increase strength and durability, all cylinders are heat-treated with a specialized quenching and tempering process in the furnace.
- Quality Checks are done using Ultrasonic waves to detect any microscopic defects.
- A valve opening is created at the top of the cylinder.
- To ensure smooth finish, the cylinders are then shotblasted both internally and externally with fine balls.
- After hydrostatic test and stamping, cylinders are moved for a second external shot blast.
- Final finishing of the product is achieved after powder coating and passing through heating oven.
