GR1 products provided by GNEE
Products Description
The GR1 Titanium Tube is a seamless, commercially pure Grade 1 titanium product made to ASTM B338 standards. It offers excellent corrosion resistance, ductility, and biocompatibility, making it ideal for chemical, marine, medical, and food applications.
Product Overview
The GR1 Titanium Tube represents the highest standard in commercially pure titanium tubing. Manufactured to meet ASTM B338 specifications, this Seamless GR1 Titanium Tube delivers exceptional corrosion resistance, unmatched formability, and excellent biocompatibility. As the softest and most ductile member of the CP titanium family, the Grade 1 Titanium Tube is ideal for industries requiring lightweight yet durable tubing in harsh chemical or marine environments.
Key Highlights:
Material: GR1 Commercially Pure Titanium (≥99.5% Ti)
Standard: ASTM B338 Titanium Tube compliance
Form: Seamless structure for superior leak resistance
Corrosion Resistance: Outstanding performance in oxidizing and reducing conditions
Application Range: Chemical processing, marine engineering, medical implants, food equipment
Material Characteristics
The GR1 Titanium Tube is widely recognized for its unique combination of physical, mechanical, and chemical properties, including:
Superior Ductility – Capable of deep drawing, cold forming, and spinning without risk of cracking.
High Corrosion Resistance – Performs exceptionally in seawater, chlorinated media, and most oxidizing acids.
Excellent Weldability – Supports TIG, MIG, plasma arc, and electron beam welding with minimal post-weld stress.
Lightweight Structure – Density of 4.51 g/cm³ ensures high strength-to-weight ratios.
Non-toxic and Biocompatible – Fully safe for food and medical-grade applications.

Manufacturing Process
Our GR1 Titanium Tubes are produced using a precise manufacturing sequence:
Raw Material Selection – Only top-grade CP titanium billets are sourced.
Piercing & Extrusion – Producing a hollow form without seams for maximum integrity.
Cold Drawing – Achieving precise OD, wall thickness, and surface finish.
Heat Treatment – Stress relief and annealing to restore ductility.
Surface Finishing – Acid pickling, bright annealing, or mechanical polishing available.
Final Inspection – Dimensional checks, NDT, and certification to ASTM B338 standards.
Quality Control & Testing
Every Seamless GR1 Titanium Tube undergoes rigorous inspection:
Chemical Analysis – Ensures compliance with CP titanium purity requirements.
Mechanical Testing – Tensile, yield, and elongation verified per ASTM standards.
Nondestructive Testing – Ultrasonic or eddy current to detect internal flaws.
Dimensional Inspection – Strict tolerances on OD, wall thickness, and straightness.
Surface Examination – Visual inspection under magnification to ensure defect-free finish.
Corrosion Resistance Performance
The Commercially Pure Titanium Tube in GR1 exhibits outstanding resistance in:
Seawater & Marine Atmospheres – No significant corrosion over decades of service.
Chlorinated Water & Brines – Resistant to pitting and crevice attack.
Mild Acids & Alkalis – Effective in nitric acid, chromic acid, and alkaline solutions.
Oxidizing Environments – Protective oxide film regenerates instantly when damaged.
Applications
The GR1 Titanium Tube is used across diverse sectors:
Chemical Processing – Heat exchangers, condensers, reactor tubing
Marine Engineering – Desalination plants, offshore oil & gas
Medical Devices – Bone implants, surgical instruments
Food Industry – Beverage processing, dairy systems
Aerospace & Defense – Hydraulic systems, instrumentation lines
