Product Description
ASTM B338 is a standard specification issued by ASTM International that defines the requirements for seamless and welded titanium (Ti) and titanium alloy tubes designed primarily for use in condensers, heat exchangers, and other high-performance applications.
Core Definition Elements:
Scope: Covers commercially pure titanium grades (Grade 1-4) and alloy grades (Grade 5, 7, 9, etc.) for various aggressive environments.
Manufacturing Processes: Includes Seamless tubes (extrusion/cold drawing) and Welded tubes (GTAW/PAW welding).
Key Requirements: Chemical composition limits, strict mechanical properties (tensile/yield strength), and precise dimensional tolerances.
Testing & Inspection: Mandates chemical analysis, hydrostatic testing, and non-destructive testing (NDT).
Packaging prioritizes protection against damage, corrosion, and contamination. Methods include Bundle Packing with steel strips, Wrapping with VCI paper/PE film, and Pallet/Frame packing for mechanical handling.
Production & Advantages
Specializing in manufacturing titanium alloy tubes, boiler tubes, and heat exchanger pipes. The facility covers 30,000M² with advanced production equipment. Annual capacity reaches 30,000 tons for seamless pipes and over 400,000 tons for various welded pipes.
After Sales Service
Quality Assurance: Warranty (1-2 years) aligned with ISO standards, including inspection reports.
Issue Resolution: 24/7 complaint handling and on-site technical support.
Technical Support: Guidance for installation, material selection, and maintenance.
Logistics: Real-time shipment tracking and customs clearance assistance.
Frequently Asked Questions
What are the main applications for ASTM B338 titanium tubes?
They are primarily used in condensers and heat exchangers across power generation, chemical processing, aerospace hydraulics, and marine desalination industries.
What grades of titanium do you offer?
We offer Commercially Pure (CP) Grades 1-4 and various alloys including Grade 5 (Ti-6Al-4V), Grade 7 (Pd-alloyed), and Grade 9 (Ti-3Al-2.5V).
Do you provide third-party inspections?
Yes, we support inspections by SGS or any other accredited third-party available to ensure material compliance.
How is the surface quality of the tubes ensured?
Tubes undergo pickling, passivation, or electropolishing to ensure they are free of cracks, folds, or delamination, as per ASTM B338 Sec. 13.
What testing methods are used for quality control?
We perform chemical spectrometry, tensile and bend testing, hydrostatic testing (1.5x design pressure), and NDT methods like Ultrasonic or Radiographic testing.
Can lengths be customized?
Yes, while standard lengths are 6m or 12m, we can provide customized lengths according to your specific project requirements.
