Proces:
- The removal of beads is done as per standard specifications.
- Bead is cold worked.
- It is brought in level with the base metal.
Before heat treatment on tube mill, bead rolling is made in-line.
This will help in recrystallization of weld structure.
The weld structure will also homogenize faster in annealing process.

- U bending is done to the required radius as per customer drawings.
- The bend portion and six inch leg is stress relieved by resistance heating.
- Inert gas (Argon) is passed through it at the required flow rate to avoid oxidation in ID.
- The radius is checked for its OD and wall thinning with the recommended specification.
- The physical properties and micro-structure is checked at three different position.
- Visual inspection for waviness and cracks is done with Dye Penetrant Test.
- Each tube is then hydro tested at the recommended pressure to check for leakage.
- Cotton ball test is done to check the ID cleanliness of the tube.
