ASTM B338 Titanium Seamless Tube Gr1 Gr2 Gr5 Gr7 Gr12 In Stock | Shaanxi Qianyi Tuoda Technology

Опубликовано Engineering Team, Shaanxi Qianyi Tuoda Technology Co., Ltd от 2026-11-02

Shaanxi Qianyi Tuoda Technology Co., Ltd, located in Shaanxi Province and backed by Baoji complete titanium industrial supply‑chain, provides comprehensive seamless titanium tube solutions for global industrial buyers. Our titanium seamless tubes are widely adopted in chemical processing, salt‑lake lithium extraction, seawater desalination, offshore oil‑gas projects, power‑plant heat‑exchanger systems and many other corrosive‑media working conditions. We support both small‑batch cut‑to‑size orders and large‑volume bulk export contracts. Our ready‑stock covers mainstream OD, wall‑thickness and length specifications, and we can also produce non‑standard sizes according to customer drawings.

All our seamless titanium tubes comply with ASTM B338 standard for heat‑exchanger and condenser tubing, also conforming to GB/T 3624‑2023 Chinese national standard. Mill Test Certificate EN 10204 3.1 is available for every shipment for customs clearance and third‑party inspection requirements. The covered material grades include commercially pure titanium Gr1, Gr2, and corrosion‑resistant alloy grades Gr7, Gr12, as well as high‑strength Ti‑6Al‑4V Gr5 titanium alloy. Different grades carry different density values: Gr1/Gr2/Gr7/Gr12 adopt density 4.51 g/cm³; Gr5 (Ti‑6Al‑4V) adopts density 4.43 g/cm³. These density parameters directly affect theoretical tube weight calculation.

We maintain permanent ready‑stock volume of 50‑60 tons across various titanium tube specifications, and our overall monthly supply capacity can reach 100 tons, which enables fast delivery for urgent project orders. Since titanium raw‑material cost is heavily influenced by titanium‑sponge market fluctuations, we do not fix static product prices. All clients shall refer to our officially released weekly price list to obtain real‑time quotation. When you place custom‑size inquiries, please send us the drawing, material grade, dimensions, tolerances, service conditions, inspection requirements, and destination for accurate quotation and lead‑time evaluation.

Mainstream Seamless Titanium Tube Specifications & Theoretical Weight Table (Standard length: 6000 mm)

Note: The weight data shown below are theoretical calculated values for reference only. Actual shipment weight shall follow MTC and physical weighing. Formula for round titanium tube: Weight per meter(kg) = π × (OD‑WT) × WT × density × 0.001; Weight per piece = weight‑per‑meter × 6.

Grade‑by‑Grade Application Guidance for ASTM B338 Titanium Tube

Gr1 and Gr2 are commercially pure titanium grades featuring outstanding general corrosion‑resistance and good ductility. Gr1 has softer property for severe forming; Gr2 is the most widely‑used general‑purpose grade for heat‑exchanger tubing, cooling‑coils and pipeline systems in chemical‑plant and seawater‑contact equipment. Gr7 and Gr12 are palladium‑ and molybdenum‑nickel‑modified titanium alloys, specially developed for reducing‑acid environments such as hydrochloric acid, sulfur‑acid mixed working‑conditions where pure titanium cannot survive. Gr5 (Ti‑6Al‑4V) is high‑strength alpha‑beta titanium alloy, selected for pressure‑bearing structural tubing that requires higher mechanical strength instead of only corrosion‑resistance.

When you prepare procurement specifications, you should confirm not only outer‑diameter, wall‑thickness and length, but also material grade, testing requirements, surface finish, non‑destructive‑test standards and certification needs. Our factory can perform eddy‑current testing, hydrostatic testing, air‑pressure leak‑testing according to ASTM B338 requirements. Surface options include pickled finish, sand‑blasted finish, polished bright finish as per customer request. Except the standard 6000 mm fixed‑length tubes listed in above table, we also supply random‑length tubes and custom‑cut short lengths.

Besides seamless titanium tubes, Shaanxi Qianyi Tuoda Technology also provides matching Titanium Plate, titanium bar, titanium flange, nickel and zirconium corrosion‑resistant metallic materials. One‑stop sourcing reduces your multi‑supplier communication cost. All export goods adopt seaworthy plywood packing for ocean freight transportation.
