Titanium Welded Pipe

Titanium welded pipe is produced by forming titanium strip or plate to size and longitudinally welding with high-purity argon shielding. It offers excellent corrosion resistance and significant weight savings compared to stainless steels. Ideal for chloride-rich, oxidizing, and many mildly reducing environments, welded titanium pipe provides a cost-effective alternative to seamless pipe in many low-to-medium pressure services.

• Commercially Pure (CP): Grade 1 (max formability), Grade 2 (balanced strength/corrosion), Grade 7 (Pd-stabilized for reducing acids)
• Alloy: Grade 12 (improved crevice/erosion in chlorides), others on request

• Corrosion resistance: Outstanding in seawater, brine, hypochlorite, and many chemical streams
• Lightweight: ~40–50% lighter than stainless, reducing system load and supports
• Clean and non-contaminating: Low ion leaching; suitable for high-purity water
• Weld integrity: Full-penetration GTAW with inside/outside shielding and optional purge dams
• Long service life: Resistant to pitting, crevice corrosion, and corrosion fatigue

• Outside diameter (OD): 19–1219 mm (¾"–48") typical range
• Wall thickness: 0.9–12.7 mm (schedule per design)
• Lengths: 1000–12000 mm; fixed or random
• Ends: Plain end (PE), beveled end (BE), or flanged per order
• Tolerances: OD ±0.5%, WT ±10% (typical) or per ASTM B862 / drawing
• Surface: Pickled, brushed, or as-welded; inside bead removed on request
• NDE: Radiographic (RT) or ultrasonic (UT) on weld seam; hydrostatic or pneumatic leak test

• Liners/cladding: Titanium lined or clad pipe sections on request
• Fittings: Matching titanium elbows, tees, reducers, flanges (ASTM B363/B381)
• Coatings/ID finish: Mechanical polishing for low Ra in high-purity service
• Marking: Grade, size, heat/lot, standard, and traceability code

• Pressure ratings: Suitable for low-to-medium pressure systems; confirm per design code and corrosion allowance
• Temperature: Stable properties from cryogenic to ~300–315°C depending on grade and medium
• Compatibility: Excellent in chlorides and oxidizers; consult for reducing acids-Grade 7/12 recommended

• Documentation: EN10204 3.1/3.2 MTC with chemistry and mechanicals
• Weld QA: Procedure Qualification Records (PQR), Welder Qualification (WQ), WPS provided when required
• Tests: Visual, dimensional, RT/UT of weld seams, hydrostatic or air-under-water leak tests
• Traceability: Heat/lot identification on pipe and paperwork

• Welding on site: Use high-purity argon purge; keep joints clean and oil-free
• Gasket selection: Use compatible non-graphitic gaskets in oxidizing chloride media
• Support: Use padded supports to avoid galling; prevent contact with dissimilar metals in wet service

• Common sizes: 10–20 working days
• Large OD/thick wall or special grades: 20–40 working days

Please specify:

• Grade and standard (e.g., Grade 2, ASTM B862)
• OD × wall thickness × length, end type (PE/BE/flanged)
• Surface finish and internal bead removal requirement
• NDE level (RT/UT), leak test type, documentation (3.1/3.2)
• Operating medium, temperature, pressure, and corrosion allowance
• Quantity and target delivery date
