Commercially Pure Titanium Grade 12 Pipe
Commercially Pure Titanium Grade 12 pipe represents a specialized titanium solution engineered for high-performance industrial applications requiring enhanced corrosion resistance. Manufactured to strict ASTM standards including ASTM B338 Gr12 for heat exchanger tubes and ASTM B861 for seamless pipes, this material features 0.2–0.4% molybdenum and 0.6–0.9% nickel additions for superior performance in reducing acid environments. LINHUI TITANIUM provides full traceability documentation per EN 10204 3.1/3.2 standards, with thickness tolerance controlled within ±0.05mm through precision cold rolling processes. Our 100% NDT inspection ensures zero-defect delivery, backed by 200+ tons stock inventory for rapid fulfillment.
Key Features & Benefits
Enhanced corrosion resistance surpasses standard CP titanium in reducing environments. Molybdenum-nickel stabilization prevents oxide film breakdown in dilute sulfuric and hydrochloric acids.
Superior weldability maintains base metal properties without filler metal degradation. Seamless construction eliminates weak corrosion points inherent in welded alternatives.
High formability allows cold bending and expansion operations without cracking. You benefit from reduced fabrication costs and shorter project timelines.

Manufacturing Process
The uniform billet structure produced by vacuum arc remelting (VAR) is devoid of macro-segregation. Trace contaminants that impair corrosion performance are eliminated by many remelts.
Seamless tubes without longitudinal welds are created by hot extrusion at regulated temperatures. Precise dimensional tolerances and improved mechanical qualities are achieved through cold pilgering.
While preserving ideal grain structure, residual stresses are relieved by solution annealing at 650–750°C. For reliable performance, quick cooling maintains the fine-grain microstructure.
Before shipping, subsurface flaws are found using eddy current and ultrasonic testing. Hydrostatic pressure testing is used to confirm the structural integrity of commercially pure titanium Grade 12 tubing.
Quality Inspection
Dimensional verification verifies that OD, wall thickness, and length meet your requirements. Chemical composition is verified by optical emission spectrometry in accordance with ASTM standards.
Tensile testing on representative samples guarantees that minimal thresholds for mechanical qualities are met. Alpha-case development or aberrant grain growth can be found via metallographic analysis.
Upon request, third-party inspection can be obtained through SGS, BV, TÜV, or DNV. Heat number traceability is documented by full material test certifications for total quality control.
Applications Of Commercially Pure Titanium Grade 12 pipe
Chemical processing includes ammonium nitrate systems that need Mo-Ni stabilization, acetic acid reactors, and chlor-alkali plants.
Oil and gas: downhole tubing in H2S conditions, sour gas condensers, and offshore platform pipe.

FAQ
Q: How does Grade 12 compare to Grade 2 titanium?
A: Grade 12 offers superior corrosion resistance in reducing acids due to Mo-Ni additions. Grade 2 excels in oxidizing environments but fails in dilute H₂SO₄ or HCl.
Q: Can you provide short lengths for testing?
A: Yes, we support sample orders starting from 100 kg. Commercially Pure Titanium Grade 12 pipe samples ship within 3 days from stock.
Q: Is welding certification required?
A: Welding should follow AWS D1.9 using ERTi-12 filler metal. We provide welding procedure specifications (WPS) upon request for critical applications.
Q: What surface finishes are available?
A: Pickled (matte), polished (bright annealed), or sandblasted finishes. Specify your requirement during quotation for proper processing.
Q: Do you offer cutting services?
A: Yes, we provide precision cutting to your specified lengths with beveled ends if needed. Additional lead time of 5–7 days applies.
