Information

Threadolet 3/4'' × 14''–36'' NPT A105 Class 3000 is a forged threaded branch outlet fitting used to create branch connections on large-diameter pipelines. The fitting is contoured to match the outside diameter of the run pipe, allowing it to be welded directly onto the pipe while providing a 3/4'' NPT female threaded outlet for branch connections. It ensures smooth flow characteristics and optimal stress distribution in high-pressure piping systems.

Available Options

• Pressure classes: Class 3000, Class 6000
• Thread types: NPT, BSPP, BSPT
• Socket Weld (SW) outlets
• Thread × SW configurations

ASTM A105 Carbon Steel

ASTM A105 is a forged carbon steel widely used for piping components and forged fittings operating at ambient and elevated temperatures. It offers excellent weldability, good machinability, and reliable mechanical properties for pressure applications.

Equivalent grades: 1.0460, C22.8, P245GH, P265GH, P285GH.

Applications

• Oil and gas transmission
• Petrochemical plants
• Power stations
• Pressure vessels
• High-pressure piping systems
• High-temperature installations
• Industrial heating systems

Each fitting is permanently marked with its size, material grade, heat number, and pressure class for full traceability.
