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.
Length: unbending length or fix length
Mill test certificate: according to EN 10204 3.2
Packing: Wooden cases, bundle or plastic bags, plywood boxes

‘U’ bending is done by cold working 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.
