Import Astm B338 Titanium Tube For Heat Exchanger — Buy in Bulk from Supplier in China

This seamless titanium tube is manufactured to ASTM B338 standards in grades Gr2, Gr7, Gr9, and Gr12, with outer diameters ranging from 3 mm to 250 mm and lengths up to 9500 mm. The supplier confirms wall thickness tolerances at ±10% of nominal and outer diameter deviations scaled by size, from ±0.15 mm for 3 - 10 mm OD to ±0.85 mm for OD above 100 mm. The tube is designed for heat exchanger and condenser applications, as well as corrosive fluid transmission systems, titanium bicycle frames, and offshore aquaculture infrastructure.

The material is commercially pure titanium or alloyed with elements like nickel, zirconium, or niobium, depending on the grade. Standard industry practice for ASTM B338 tubes includes seamless processing, with typical surface finishes such as pickled or polished. For heat exchanger use, typical thermal conductivity values for Gr2 titanium are around 17 W/m·K, and the material offers excellent resistance to corrosion in chloride-rich environments, a standard expectation for this product category.

Buyers in chemical processing, marine engineering, and high-performance automotive sectors use these tubes for their lightweight, high strength-to-weight ratio, and resistance to pitting and crevice corrosion. The supplier offers plywood case packaging lined with foam, with a minimum order quantity of 10 kg and lead times between 3 to 20 days. Payment terms include T/T in advance or irrevocable L/C at sight, with certification to ISO 9001 and EN10204 3.2 provided. Non-destructive testing, such as ultrasonic, eddy current, and hydraulic tests, is performed as part of quality control.
