Production Steps & Quality Control

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 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.

Product Packaging & Details

Frequently Asked Questions (FAQ)

What are the main applications of AISI 2205 (UNS S31803) stainless steel exchanger pipes?

AISI 2205 exchanger pipes are widely used in demanding environments, including seawater coolers, condensers, evaporators, heaters, and reheaters. They are ideal for chemical, petroleum, power stations, ship pressure piping, and other high-temperature or highly corrosive environments.

What materials and grades are available for these heat exchanger tubes?

We supply heat exchanger tubes in an extensive range of materials including ASTM A213 S304/304L, 316/316L, 317L, 321/321H, 410, and Duplex 2205 (UNS S31803). We also support titanium, nickel alloys, and zirconium versions.

How do you ensure the U-bend tubes are free from leakage and defects?

Each U-bend tube undergoes rigorous quality checking at every production stage. Quality control includes hydrostatic testing at recommended pressures, dye penetrant tests for surface defects, dimensional check for wall thinning, and physical/micro-structure properties verification.

Why are titanium tubes utilized in these applications?

Pure titanium tubes feature superior corrosion-proof abilities, high intensity, excellent heat resistance, and high conductivity. They are non-toxic, resist scaling and blocking, prevent contamination of the medium, and do not easily form surface oxides.

What are the typical packaging and delivery protection options?

To prevent surface damage and environmental impact, tubes are temporarily protected on both inner and outer surfaces with a light mineral oil film. They are then packed in individual woven bags and shipped in seaworthy wooden cases.

Can you customize U-bend tubes to specific project drawings?

Yes, our U-bend tubes are manufactured strictly in accordance with customer-provided drawings and dimensions. To avoid oxidation during the fabrication process, an inert gas (Argon) is passed through the inner diameter of the tubes at required flow rates.
