gr2 titanium pipe for heat exchanger

GR2 Titanium Pipe for Heat Exchanger

ASTM B338, B337, B861, and B862-compliant high-performance gr2 titanium pipe for heat exchanger applications is produced by XI AN LINHUI IMPORT AND EXPORT Co., LTD. With lengths up to 8000mm and outside diameters ranging from 3mm to 203.2mm, our seamless and welded titanium pipes offer unparalleled corrosion resistance in harsh fluid conditions.

Each pipe uses controlled cold rolling technique to maintain thickness tolerance within ±0.05mm, supported by 100% NDT inspection and EN 10204 3.1/3.2 traceability. Serving more than 60 countries in the marine, chemical processing, and desalination industries, we guarantee quick delivery of typical orders within 3–7 days thanks to our more than 200 tons of stock inventory.

Key Features & Benefits

Increased Resistance to Corrosion

The heat exchanger's gr2 titanium pipe creates a self-healing TiO₂ oxide layer that offers complete protection against chloride attack in brine and seawater solutions. Costly downtime brought on by pitting and crevice corrosion will be eliminated.

Zero-Defect Assurance of Quality

Each pipe is subjected to eddy current testing (ET) and ultrasonic testing (UT) in accordance with AMS 2631 to identify surface flaws and subsurface cavities. Pressure integrity is checked against ASTM limits via hydrostatic testing.

Welded and Seamless Options

For optimal pressure resistance, seamless pipes (ASTM B861) remove weld weak areas. Base metal corrosion characteristics are preserved in welded pipes (ASTM B862) without compromising filler metal.

Product information

Manufacturing Process

Raw Material Selection

We source titanium sponge from certified mills with full heat number traceability to guarantee metallurgical purity.

Extrusion & Cold Rolling

Seamless pipes undergo precision extrusion followed by controlled cold rolling to achieve tight dimensional tolerances. Welded pipes use TIG welding without filler metal to preserve corrosion resistance.

Heat Treatment

Stress-relief annealing at 650–750°C eliminates residual stress from forming operations, enhancing mechanical stability.

Surface Treatment

Pickling in HF-HNO₃ solution removes oxide scale, creating a clean, passive surface ready for installation.

Quality Inspection

· Ultrasonic Testing (UT): Detects internal delamination per AMS 2631

· Eddy Current Testing (ET): Identifies surface cracks and defects

· Hydrostatic Testing: Verifies pressure holding at 1.5× design pressure

· Flattening & Flaring Tests: Confirms ductility without cracking

· PMI Analysis: Validates Grade 2 composition, preventing material substitution

· Dimensional Verification: Laser measurement ensures ±0.05mm accuracy

Applications Of gr2 titanium pipe for heat exchanger

Central Cooling Systems for Marines

Our pipes are used in shipboard heat exchangers, which require exceptional endurance due to silt erosion and seawater velocity. Titanium is resistant to impingement assault and biofouling.

Production of Chlor-Alkali

Where stainless steel quickly fails, the gr2 titanium pipe for the heat exchanger maintains process purity by handling moist chlorine gas and hypochlorite solutions.

Desalination of Seawater (SWRO & MSF)

These pipes endure concentrated brine and temperature cycling without pitting in reverse osmosis and multi-stage flash plants, guaranteeing long-term dependability.

Platforms for Offshore Oil and Gas

The ability of titanium to withstand H2S, CO2, and chloride stress cracking is essential for heat recovery systems at offshore sites.

FAQ

Q: What distinguishes welded titanium pipes from seamless ones?

A: Higher pressure ratings without weld seams are provided by seamless pipes (B861). For lower-pressure applications, welded pipes (B862) are affordable and resistant to corrosion.

Q: Is it possible for you to supply modest amounts of samples for testing?

A: We do accept trial orders with the same quality criteria as bulk orders, starting at 100 kg.

Q: How can material authenticity be guaranteed?

A: To confirm authentic Grade 2 composition, we conduct Positive Material Identification (PMI) testing on each batch, confirming iron and oxygen concentration.

Q: What certifications do you offer?

A: Third-party inspection reports from SGS, BV, or TÜV upon request; ISO 9001:2015; PED 2014/68/EU; EN 10204 3.1/3.2 certificates.

Q: How long does it usually take you?

A: Stock orders are shipped in three to seven days. Production typically takes 15 to 25 days. Depending on availability, rush orders may be expedited.
