ASTM B862 Ti2 Titanium Alloy Welded Pipe For Chemical Processing
The ASTM B862 Ti2 Welded Pipe is a titanium alloy pipe manufactured according to the specifications set by the ASTM International (American Society for Testing and Materials) under standard B862. This standard governs the production of titanium and titanium-alloy welded pipes for industrial applications. Grade Ti2, also known as Grade 2 titanium, is a commercially pure titanium material known for its excellent corrosion resistance, high strength-to-weight ratio, and superior weldability.
Key Features of ASTM B862 Ti2 Welded Pipe
-
Material: Grade 2 Titanium (Ti2)
- Titanium Grade 2 is unalloyed and classified as commercially pure titanium (CP Ti).
- It offers moderate strength, excellent corrosion resistance, and good formability.
- Grade 2 titanium is widely used in chemical processing, marine environments, and medical applications.
-
Manufacturing: Welded Pipe
- The pipe is produced by welding titanium sheets or plates and then subjecting the weld area to heat treatment for uniform mechanical properties.
- Welded pipes provide cost-effective solutions compared to seamless pipes for certain applications.
-
Key Properties:
- Corrosion Resistance: Exceptional resistance to oxidizing and mildly reducing environments, including seawater, chlorine, and many chemical compounds.
- Strength and Ductility: Moderate tensile strength (around 345 MPa) with good ductility, making it easy to form and weld.
- Lightweight: Titanium’s low density provides high strength while maintaining a lightweight structure.
-
Compliance with ASTM B862 Standard
- Pipes are manufactured and tested according to strict guidelines to ensure quality, consistency, and performance.
Applications
Due to its excellent performance characteristics, ASTM B862 Ti2 welded pipes are widely used in industries such as:
- Chemical Processing: Piping systems for corrosive chemicals, acids, and alkalis.
- Marine Engineering: Components exposed to seawater and marine environments.
- Aerospace: Lightweight and corrosion-resistant parts for aircraft and space systems.
- Power Generation: Heat exchangers and condensers in power plants.
- Medical Equipment: Biocompatible material used in surgical instruments and implants.
- Desalination Plants: Piping and systems for converting seawater into potable water.
