Extruded Gr2 Titanium Tubing

Of the four commercially pure (CP) titanium grades, Grade 2 titanium EFW tubing is typically used in applications requiring excellent corrosion resistance in a variety of corrosive media. These Grade 2 Titanium ERW tubes offer excellent corrosion resistance, superior formability, and strength between Grades 1 and 3. Grade 2 Titanium round tubes are metals containing a mixture of titanium and other chemical elements. These Grade 2 titanium square tubes are used to manufacture machined parts with purity levels and mechanical properties between Grade 1 and Grade 3 specifications. Commercially pure titanium grade 2 tubing is one of the most common unalloyed titanium grades.

Selecting the right tubing material depends on the operating environment, corrosion conditions, temperature, pressure, and budget. Gr2 Titanium Tubing (UNS R50400) is widely recognized for its outstanding corrosion resistance, lightweight properties, and long service life, making it a preferred choice for marine, chemical, desalination, and heat exchanger applications.

To ensure Gr2 Titanium Tubing arrives in perfect condition, we use export-standard packaging designed to prevent surface damage, contamination, deformation, and corrosion during transportation. Packaging can also be customized to meet customer or project requirements.

Packaging Item	Description
Surface Protection	Each tube is covered with a plastic sleeve or protective film to prevent scratches and contamination.
End Protection	Plastic end caps are installed on both ends to prevent damage and the entry of dust or moisture.
Bundling	Tubes are securely bundled with non-metallic straps or protective wrapping to avoid surface damage.
Inner Packaging	Waterproof plastic film and moisture-proof materials are used for additional protection during storage and transport.
Outer Packaging	Fumigation-free plywood cases, wooden crates, or export cartons depending on product size and shipping method.
Marking	Each package is labeled with material grade, size, heat number, standard, quantity, and customer identification.
Shipping Methods	Suitable for sea freight, air freight, rail transportation, and express delivery.
Quality Documents	EN 10204 3.1 MTC, packing list, commercial invoice, certificate of origin, and third-party inspection reports available upon request.
Customization	OEM labels, custom packaging, special export markings, and project-specific packaging are available.
