Titanium & Titanium Alloy Tube for Critical Corrosive Service

Specifications by Grade – Pipe and tube

A specification is written for a product form. The standards below are the ones that cover pipe and tube; the plate, bar and tube specifications for these grades are different documents and are listed on their own pages.

Grade	UNS	Pipe and tube specification
Grade 1	R50250	ASTM B338 / B861
Grade 2	R50400	ASTM B338 / B861
Grade 5	R56400	ASTM B338 / B861
Grade 7	R52400	ASTM B338 / B861
Grade 9	R56320	ASTM B338 / B861
Grade 11	R52250	ASTM B338 / B861
Grade 12	R53400	ASTM B338 / B861
Grade 23	R56407	ASTM B338 / B861

Product Forms, Sizes & Availability

Titanium and titanium alloy tubes are produced in seamless and welded forms, with hot and cold finishing routes depending on grade and final size range, under ASTM B338 and related specifications.

Supply Conditions

Seamless tubes from hollow billets via cold drawing or cold reducing to achieve tight dimensional control and surface finish.
Welded tubes from strip with full penetration welding and subsequent cold work and heat treatment where specified.
Straight lengths and U‑tubes for condensers and heat exchangers, typically supplied with cleaned internal surfaces ready for fabrication.

Typical Dimensional Range

Outside diameter from small instrumentation sizes up to large condenser tube diameters, depending on grade and production route.
Wall thickness tailored to design pressure and corrosion allowance, aligned with ASME and project specifications.
Length options spanning short cut pieces to long exchanger lengths, with tight cut tolerance and end conditioning for welding.

For integrated projects, tubes are often supplied alongside titanium plate, pipe, fittings, and machined parts such as titanium hex bar to ensure full material traceability across the BOM.

Frequently Asked Questions on Titanium & Titanium Alloy Tubes

ASTM B338 is the primary standard for seamless and welded titanium and titanium alloy tubes used in condensers, heat exchangers, and similar equipment. It defines chemistry, mechanical properties, dimensional tolerances, and test requirements for 28 grades, ensuring that tubes from different mills are comparable and suitable for critical industrial service.

Grade 2 titanium tube offers moderate strength with excellent formability and corrosion resistance, making it a strong default choice for many chemical, marine, and utility services. Grade 9 (Ti‑3Al‑2.5V) provides higher strength and fatigue performance while remaining cold workable, so it suits higher pressure, vibration-prone, or weight-sensitive systems such as compact heat exchangers and aerospace or offshore modules.

Titanium tubes do carry a higher initial material price than common stainless steels, but they often deliver much longer service life and allow thinner walls, lighter bundles, and reduced unplanned outages. For cooling water, seawater, and aggressive chemical duties, many operators find that the lower replacement frequency and improved uptime make titanium the lowest lifecycle cost option over the life of the plant or offshore asset.

Titanium tubes are readily weldable using established GTAW and orbital welding procedures, provided that shielding from air is carefully maintained to avoid contamination. Fabricators typically qualify WPS and PQR against the relevant ASTM and ASME requirements and may use matching filler metals or compatible titanium hex bar and fittings, delivering reliable tube-to-tubesheet and field welds with controlled heat input and distortion.

Global titanium demand is growing around 6% annually, with aerospace, automotive, medical, and industrial applications playing major roles in volume growth. In the tube segment, power generation, chemical processing, oil and gas, marine, and desalination are particularly important, as they rely on titanium’s high strength‑to‑weight ratio and corrosion resistance to keep critical assets running efficiently in harsh environments.

Quality Assurance, Testing & Export Readiness

Buyers of titanium tubes increasingly look for mills and distributors who can demonstrate robust quality systems, traceability, and familiarity with multi‑standard projects combining ASTM, ASME, DIN, and EN requirements.

Manufacture and supply under ASTM B338, B861, and related specifications with documented heat‑wise chemistry and mechanical test results.
Mechanical testing to specified yield, tensile, and elongation values, along with hardness and flattening tests as required.
NDT such as eddy current, ultrasonic or hydrostatic testing to verify leak‑tightness and integrity of tube bodies and welds.
Dimensional inspection for OD, wall thickness, ovality, straightness, and surface finish, with EN 10204 3.1 or 3.2 certificates for export projects.
Documentation support for ASME code stamping, PED compliance, and region‑specific regulatory requirements across Asia, Europe, and the Middle East.

With Asia Pacific accounting for roughly 40% of global titanium consumption and strong growth in India and China, exporters that can coordinate titanium tube supply from India with compliant paperwork and logistics are well positioned to serve international OEMs and EPC contractors.
