Qq20200218213416

Process :

1 . We use Cold Rolled and Cold Drawn techonology to produce U bend tube

2 . U bend tube produce will in accordance with the customer's drawings
3 . To avoid oxidation, inert gas (Argon) is passed through tubes ID at the required flow rate
4 . The radius is checked for its OD and wall thinning with the recommended specification
5 . We'll choose three different positions or as customer's request to make sure of the tubes quality. We'll test mechnical properties and micro-structure tests
6 . Visual inspection for witness and cracks will be done with Dye Penetrant Test
7 . Each tube shall be done Eddy current test and Hydrostatic test at the recommended pressure to check for leakage


Technical Requirements.

Straight Tubes Standard Specification For Bending:

ASME SA 213; ASME SB 163; ASME A789, ASME SA268, ASME SA269, etc.

Marking: Before Bending By Marking Machine All Over The Tube Length (Bent Section After Heat Treatment Without Marking)

Note: Marking is also possible After bending on the straight parts of U bend Tube.
