U-Bend Manufacturing Process & Quality Steps
- We use Cold Drawn techonology to produce U bend tube
- U bend tubes produce 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 position 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
What materials are available for the heat exchanger tubes?
The heat exchanger tubes are available in an extensive range of austenitic stainless steels, duplex stainless steels, nickel alloys, titanium, and zirconium. They are suitable for seawater coolers, condensers, evaporators, heaters, and reheaters.
What standard and grades of stainless steel 316 exchanger pipes do you produce?
Our standard grades commonly include ASTM A213 S304/304L, 316/316L, 317L, 321/321H, 410, and Duplex 2205 (UNS S31803) under the ASTM A312, ASTM A269, and 213 standards.
How do you verify the quality of the U-bend tubes?
We employ a rigorous process that includes Cold Drawn technology, ID purging with inert gas (Argon) to avoid oxidation, checking dimensions (OD and wall thinning), physical and micro-structure testing, Dye Penetrant Testing for cracks, and hydrostatic testing at recommended pressures.
How are the tubes protected during delivery?
Unless otherwise requested, the tubes are delivered with their inner and outer surfaces temporarily protected with a light mineral oil film. They are supplied plain, square cut, and can be deburred on request. They are wrapped in woven bags and packed in seaworthy wooden cases.
What quality tests are conducted for the oil and gas control lines?
Finished product testing includes non-destructive tests, hydrostatic tests, surface finish controls, dimensional accuracy measurements, flare/coning tests, and mechanical and chemical property testing.
What are the primary applications for your capillary tubes?
Our precision capillary tubes are widely used in medical devices, industrial temperature sensors, antennas, electronic small-diameter instruments, watch parts, laser engraving equipment, printer components, heating pipes, and dispensing needles.
