Manufacturing & Quality Controls
- We use Cold Drawn technology to produce U bend tube.
- U bend tubes production will accordance to customer's drawings.
- To avoid oxidation, inert gas (Argon) is passed through tubes ID at the required flow rate.
- The radius is checked for its OD and wall thinning with the recommended specification.
- We'll choose three different positions or as customer's require to make sure tubes quality. We'll do physical properties and micro-structure test.
- 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.

Frequently Asked Questions (FAQ)
What standards and grades are available for these heat exchanger pipes?
Our exchanger pipes are manufactured commonly under ASTM A312, ASTM A269, and ASTM A213 standards. Available grades include S304/304L, 316/316L, 317L, 321/321H, 410, and Duplex 2205 (UNS S31803).
What industries commonly use the Stainless Steel 304 Exchanger Pipes?
These pipes are widely utilized in process and high-specification industries, including petroleum, chemical processing, oil refining, hydrocarbon processing, power stations, ship pressure piping, aerospace, and nuclear power generation.
How is oxidation prevented during the production of U-bend tubes?
To prevent oxidation on the inside surface of the tubes during thermal processing and bending, inert gas (Argon) is consistently passed through the tubes' inner diameter (ID) at a controlled flow rate.
What quality control and testing processes are performed on the finished tubes?
Every tube undergoes rigorous quality checking, including hydrostatic testing at recommended pressures, non-destructive testing, Dye Penetrant testing for surface cracks/waviness, surface finish controls, and physical property / micro-structure checks.
How are the exchanger pipes protected during shipping and delivery?
Unless specified otherwise by the customer, all tubes are delivered with inner and outer surfaces temporarily coated with a light mineral oil film for rust protection. For packaging, each piece is wrapped in a woven bag and securely packed in seaworthy wooden cases.
Can you customize U-bend tubes to specific project blueprints?
Yes, we manufacture and bend U-bend tubes in strict accordance with the customized technical drawings provided by the customer, ensuring dimensional accuracy of the outer diameter (OD) and wall thinning tolerances.
