ASTM B862 Titanium Welded Pipe
Using cutting-edge TIG/PAW welding technology, LINHUI Titanium produces superior ASTM B862 Titanium Welded Pipe without the need of filler metal. We produce Grades 1, 2, 7, 9, and 13 with outer diameters between 6.35 and 1219.2 mm, wall thicknesses between 0.5 and 40 mm, and lengths between 3000 and 12000 mm.
To ensure there are no flaws, every Titanium Welded Pipe is subjected to 100% ultrasonic and eddy current testing. In harsh chemical environments, the weld seam maintains the same corrosion resistance as base metal, guaranteeing dependable performance. By removing residual tensions, our exclusive stress-relief annealing method stops stress corrosion cracking in media that are high in chloride.
With 200+ tons stock inventory and 15-25 days standard production cycle, we deliver cost-effective solutions for large-bore piping systems where seamless options become prohibitively expensive.
Key Features & Benefits
Superior Weld Integrity
Our autogenous welding process ensures the weld zone chemistry matches base metal composition perfectly. This eliminates weak corrosion points common in filler-added welds.
Extended Service Life
In seawater and chemical processing conditions, zero-corrosion allowance design offers 40+ years of maintenance-free operation. Compared to conventional alloys, this significantly lowers lifecycle costs.
An Economical Large Diameter Solution
For diameters larger than 300 mm, where seamless pipe manufacture becomes technically difficult and costly, ASTM B862 Titanium Welded Pipe provides affordable options.

Manufacturing Process
Step 1: Getting the Material Ready
We choose high-quality titanium coils and plates that adhere to ASTM B265 requirements. Before forming operations start, the material is chemically verified.
Step 2: Welding and Forming
The flat-rolled product is exactly shaped like a tube. By joining edges without the use of filler metal, autogenous TIG or PAW welding preserves base metal purity throughout the weld zone.
Heat Treatment in Step Three
Remaining strains are removed by post-weld stress-relief annealing at regulated temperatures. In service circumstances, this crucial phase stops stress corrosion cracking.
Dimensional Calibration in Step Four
For typical grades, cold sizing techniques yield tight diameter tolerances of ±0.5mm.
Quality Inspection
Testing that is completely non-destructive
To find any internal discontinuities or surface flaws in the weld region, every Titanium Welded Pipe is subjected to eddy current inspection and ultrasonic testing.
Hydrostatic Pressure Testing
In order to ensure structural integrity under operating conditions, each pipe is pressure tested to confirm leak-tightness at calculated industry pressures.
Mechanical Examination
Weld ductility is verified using flattening and guided bend tests. Tensile specimens confirm that the weld strength matches or surpasses the qualities of the base metal.
Verification of Chemical Analysis
Spectrometric analysis prevents embrittlement problems by verifying that interstitial element content remains within specification limits.
Complete Traceability Documentation Using heat numbers, EN 10204 3.1/3.2 certificates offer complete material traceability. SGS, BV, TÜV, DNV, or ABS offer third-party inspection services.

Applications Of ASTM B862 Titanium Welded Pipe
Chemical Processing Industry Titanium Welded Pipe is the industry standard for handling brine and transporting wet chlorine gas in chlor-alkali plants. Decades of dependable service are guaranteed by the material's resistance to pitting corrosion in chloride conditions.
Plants for Desalination
These pipes are used for reject stream piping and brine heaters in multi-stage flash evaporators and reverse osmosis systems. Thinner walls are made possible by superior crevice corrosion resistance, which lowers structural loads.
Facilities for Power Generation
ASTM B862 pipes are used in seawater cooling systems and surface condensers in coastal and nuclear power facilities. Over 40 years of maintenance-free operation are provided by zero corrosion allowance.
Offshore Gas and Oil
Titanium's resistance to erosion and corrosion is advantageous for topside pipe systems that handle generated water. The material does not deteriorate when exposed to high-velocity fluid flow.
Production of Pharmaceuticals
These pipes are perfect for aggressive reagent transfer and ultra-pure water distribution because of their FDA-compliant grades and clean-room compatible surface treatments.

FAQ
Q: What distinguishes ASTM B862 pipes from B861 pipes?
A: B862 pipes are inexpensive for big diameters since they are welded from flat-rolled items. Seamless B861 pipes are recommended for high-pressure applications that demand the highest level of integrity.
Q: Can you offer Grade 7 for environments with extremely high acidity?
A: In order to provide better resistance to reducing acids like hydrochloric and sulfuric acid, our Grade 7 does indeed include palladium. In harsh chemical operations, this grade greatly increases service life.
Q: What tolerance for wall thickness are you able to attain?
A: For welded pipes, the standard tolerance is ±10%. We provide cold-worked options with ±5% tolerance for precision applications that need more control.
Q: Are custom length cuts supported?
A: Definitely. Although normal lengths are between 3000 and 12000 mm, we offer precise cutting services to meet your exact requirements with little extra lead time.
Q: How is the quality of the weld ensured?
A: 100% ultrasonic and eddy current test is performed on each weld. To confirm mechanical integrity and leak-tightness, we also conduct hydrostatic pressure testing and guided bend tests.
