Delivery Time 20-60 Days after receiving the deposit (Normally according to the order quantity)

Price Item FOB, CIF or as negotiation

Payment T/T (30% in advance, 70% against the BL Copy) or as negotiation

Quality Requirement Mill Test Certificate will be supplied with shipment, Third Party Inspection is acceptable

Surface protection Unless otherwise stated in order, tubes are delivered with inner and outer surfaces temporarily protected with a film of light mineral oil.

Tubes ends The tubes are supplied plain, square cut and on request the tubes can be deburred.

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

Q1: What standard specifications and grades do these exchanger pipes support?

Our heat exchanger tubes are manufactured in accordance with ASTM A312, ASTM A213, and ASTM A269. Commonly available steel grades include ASTM A213 S304/304L, 316/316L, 317L, 321/321H, 410, and Duplex 2205 (UNS S31803).

Q2: How is oxidation prevented during the production of U-bend tubes?

To completely prevent internal oxidation during production, we pass an inert gas (Argon) through the inside diameter of the tubes at a strictly regulated flow rate.

Q3: What types of quality control and testing processes are performed on these tubes?

We perform rigorous testing throughout the manufacturing stages, including non-destructive tests, hydrostatic tests at recommended pressures, dimensional accuracy measurements, Dye Penetrant Testing for waviness and cracks, and physical/microstructure checks at three different positions.

Q4: What surface finishes and end preparations are provided?

The tubes are supplied with an annealed or polished surface finish. Unless stated otherwise, the inner and outer surfaces are temporarily protected with a thin film of light mineral oil. The ends are supplied plain and square cut, with deburring available upon request.

Q5: What are the main applications of these stainless steel capillary tubes?

These precision capillary tubes are widely used in medical devices, industrial temperature sensors, instrumentation thermometers, electronic equipment, micro-tube antennas, printer box needles, and decorative/construction accessories.
