Manufacturing & Inspection Process

We use Cold Drawn technology 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 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

Q What are the main standards and grades for these heat exchanger pipes?

Our pipes are manufactured under standards such as ASTM A312, ASTM A269, and ASTM A213. Common grades include S304/304L, 316/316L, 317L, 321/321H, and Duplex 2205 (UNS S31803).

Q What testing procedures do the U-bend and coiled tubes undergo?

We perform non-destructive tests, hydrostatic testing at recommended pressures, dimensional accuracy measurements, flare and coning tests, chemical and mechanical property testing, and Dye Penetrant tests for waviness and cracks.

Q In what industries are stainless steel capillary tubes applied?

Capillary tubes are widely used in medical devices, industrial temperature control systems, micro-tube antennas, electronic components, auto antennas, printer components, and various precision dispensing needles.

Q How is oxidation prevented during the production of U-bend tubes?

To prevent internal oxidation during production, an inert gas (Argon) is passed through the tube's inner diameter (ID) at the required flow rate.

Q What surface protection is applied to the pipes before delivery?

Unless otherwise specified by the customer, all tubes are delivered with their inner and outer surfaces temporarily protected with a light mineral oil film.

Q What are the typical lead times and packaging for orders?

Orders are usually delivered within 20 to 60 days after receiving the deposit, depending on the quantity. Each piece is individually wrapped in a woven bag and packed securely in seaworthy wooden cases.
