BSPT Threaded Couplings for Reliable Piping Connections
The BSPT threaded coupling is widely used where welding is not practical or where easy installation and maintenance are required. Its tapered thread profile provides a tight mechanical seal, making it suitable for a variety of industrial piping applications.
This shipment covers multiple pipe diameters, allowing the customer to assemble different sections of the pipeline while maintaining consistent thread compatibility. Each BSPT threaded coupling was manufactured with precise thread machining to ensure smooth installation and dependable sealing performance.

Consistent Manufacturing and Surface Treatment
To achieve stable product quality, Haihao Group follows strict manufacturing and inspection procedures throughout production.
For this Montenegro project, every BSPT threaded coupling received a black shot-blasted finish, which removes surface scale and provides a clean, uniform appearance before shipment. Dimensional accuracy and thread quality were carefully inspected to ensure compliance with BSPT requirements.
Quality control included:
- Precision BSPT thread machining
- Dimensional inspection
- Visual surface examination
- Black shot blasting for improved surface quality
- Final inspection before export packaging
These procedures ensure that every BSPT threaded coupling arrives ready for installation with reliable performance in the field.
