Information
Half Coupling 3/4'' BSPT A105 Class 6000 – 413 Bar is a high-pressure threaded weld-on fitting used to create female threaded branch connections on pressure vessels, tanks, and pipelines. The tapered BSPT thread provides a leak-tight connection, while the forged A105 body ensures excellent mechanical strength and durability in demanding industrial environments.
Each fitting is permanently marked with its size, material grade, heat number, and pressure class for complete traceability. A 3.1 material certificate is available on request.
Advantages
- Easy selection of thread type and material grade
- Excellent weldability
- High mechanical strength
- Reliable sealing with BSPT tapered thread
- Suitable for high-pressure applications
ASTM A105 Carbon Steel
ASTM A105 is a forged carbon steel widely used for piping components, flanges, valves, and forged fittings operating at ambient and elevated temperatures. It offers excellent machinability, weldability, and reliable performance in pressure systems.
Equivalent grades: 1.0460, C22.8, P245GH, P265GH, P285GH.
Applications
- Boilers
- High-pressure piping systems
- High-temperature installations
- Oil refineries
- Marine industry
- Steel industry
- Ships
- Industrial machinery
- Pressure vessels
