Seamless GR2 Titanium Tube For Pipework

Grade2 pure titanium tube in the humid atmosphere and seawater media work, its corrosion resistance is far better than stainless steel; pitting, acid corrosion, stress corrosion resistance is particularly strong; alkali, chloride, chlorine, organic items, nitric acid, sulfuric acid, etc. have excellent corrosion resistance. But titanium has reducing oxygen and chromium salt media corrosion resistance is poor.

Specifically designed for high-surface-quality mirror-finished sheets, polished strips, and thin-walled tubes. Each product is first placed in a PE sealed bag, then fully wrapped with soft non-woven fabric + pearl cotton padding. Individually compartmentalized foam mold inserts are used to secure each piece, and the products are placed into high-strength, crush-resistant cartons. The outer cartons undergo a "sealed film + tape" fully enclosed moisture-proof treatment and are affixed with "Precision Surface · Handle with Care" warning labels to prevent scratches and contamination during transit.

1. What is a Gr2 Titanium Round Pipe?

A Gr2 Titanium Round Pipe is a round pipe manufactured from Grade 2 commercially pure titanium (UNS R50400). It offers an excellent combination of corrosion resistance, moderate strength, lightweight properties, and weldability, making it one of the most widely used titanium pipe products for industrial applications.

 

2. What is the difference between Grade 2 and Grade 1 Titanium?

Both are commercially pure titanium grades with excellent corrosion resistance. Grade 2 provides higher tensile and yield strength, making it suitable for pressure piping, heat exchangers, and marine applications, while Grade 1 offers better ductility and formability for applications requiring extensive cold working.

 

3. What standards are available for Gr2 Titanium Round Pipes?

Our Grade 2 Titanium Round Pipes can be manufactured according to:

ASTM B861

ASTM B338

ASME SB861

ASME SB338

ASTM B337 (upon request)

Custom production according to customer specifications is also available.

 

4. What sizes can you supply?

Our standard production range includes:

Outside Diameter (OD): 6 mm – 219 mm

Wall Thickness (WT): 0.5 mm – 20 mm

Length: Up to 12,000 mm

Custom dimensions and cut-to-length services are available.

 

5. Do you offer seamless and welded titanium pipes?

Yes. We supply both seamless and welded Grade 2 Titanium Round Pipes. Seamless pipes are recommended for high-pressure and critical applications, while welded pipes provide an economical solution for general industrial use.
