Manufacturing Process & Testing

1
We use Cold Drawn technology to produce U bend tube.
2
U bend tubes production will be in accordance with 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 requires to make sure tubes quality, conducting physical properties and micro-structure tests.
6
Visual inspection for waviness and cracks is performed with the Dye Penetrant Test.
7
Each tube is then hydro tested at the recommended pressure to check for leakage.

Frequently Asked Questions

Q1: Which standards and grades are available for these heat exchanger pipes?

A1: These pipes commonly comply with ASTM A312, ASTM A269, and ASTM A213 standards. Commonly supplied grades include S304/304L, 316/316L, 317L, 321/321H, 410, and Duplex 2205 (UNS S31803).

Q2: How are the quality checks performed on the U bend tubes?

A2: Each U bend tube undergoes rigorous verification, including checking the radius for outside diameter (OD) and wall thinning, physical properties and micro-structure testing, Dye Penetrant Tests to detect waviness and cracks, and hydrostatic leakage testing at the recommended pressures.

Q3: How are the surfaces and tube ends protected and prepared for shipment?

A3: Unless specified otherwise, the inner and outer surfaces are temporarily protected with a thin film of light mineral oil. Tube ends are supplied plain and square-cut, and they can be deburred upon customer request.

Q4: What types of quality assurance tests are conducted on completed products?

A4: Typical quality assurance tests include non-destructive tests, hydrostatic tests, surface finish checks, dimensional accuracy measurements, flare and coning tests, and mechanical and chemical properties verification.

Q5: In what applications are capillary tubes used?

A5: Precision capillary tubes are utilized in medical devices, temperature sensors/thermometers, industrial antennas, precision watch elements, laser engraving units, printer needles, heating/oil industrial processes, and microphone or audio equipment components.

Q6: What packaging is standard for delivery?

A6: Each individual piece is protected by a woven bag, and then safely packed inside seaworthy wooden cases to ensure safe transportation globally.
