What is the difference between BSP and BSPT？

BSP thread and BSPT thread are two common thread connection methods that are widely used in industrial production. Their advantages and application scenarios are different, and different connection methods can be used for different situations to better exert their effectiveness.

1. BSP thread

BSP thread, also known as British standard thread, is a type of thread with a taper of 55 degrees, which presents a parallel linear shape. Unlike American standard threads, BSP threads do not have rounded corners. BSP thread is a commonly used thread on pipes produced and circulated in the UK. In addition, BSP thread has excellent sealing performance, effectively preventing pipe oil leakage and plays an important role in the long-term stable operation of equipment.

2. BSPT thread

BSPT thread, also known as tapered pipe thread, is a type of thread with a taper of 60 degrees. Due to its larger taper than BSP thread, its sealing performance is superior to BSP thread. The difference lies in the smaller pitch of the BSPT thread and the thinner wall thickness of the pipe.

BSPT threads are very common in European and Asian countries.

3. Dimensions of BSP threads and BSPT threads

British threads also use nominal sizes, such as 1/8, 1/4, 3/8, 1/2, etc., and their contour dimensions are the same. But the tooth angles of these two types of threads are different, and the pitch of some sizes is also different. The naming convention for BSPP/BSPT threads is as follows: thread type nominal size pitch. (Type: G=BSPP, R=BSPT)

4. Differences between the two

The biggest difference between BSP threads and BSPT threads is their taper. The taper of BSP thread is 55 degrees, while the taper of BSPT thread is 60 degrees. Depending on this taper, these two types of threads also have other differences:

1. BSP threads exhibit a parallel linear shape, while BSPT threads have a conical shape.

BSP threads do not have rounded corners, so the surface is smoother, while BSPT threads have sharper edges.

3. BSP threads are more suitable for use with hoses, while BSPT threads are more suitable for iron pipes and steel pipes.

4. The accuracy requirements for BSP threads and BSPT threads are also different, and the accuracy of BSP threads can be lower than that of BSPT threads.

5. Scope of application

Due to the significant differences in the design of BSP threads and BSPT threads, their applicability is also different.

BSP threads are suitable for hose connections used in smaller pressures and wider temperature ranges. BSP threads have excellent sealing properties and will not leak gas or water, making them widely used in high-pressure gas pipeline connections. BSP threads are also widely used in the petroleum and natural gas industries, where hoses are often used for connections.

BSPT threads are more widely used in higher pressure and temperature environments. BSPT threads have better sealing properties and can withstand higher pressures and temperatures. Therefore, it is widely used in the pipeline connection of high-pressure equipment such as petrochemical industry, boilers, heaters, and compressors.

7. Conclusion

In summary, both BSP threads and BSPT threads have their own advantages and application scenarios. In production and use, appropriate connection methods should be selected according to actual needs. Regardless of the type of threaded connection, it should be operated and used according to standards to ensure the safety and stability of equipment and production. Only in this way can we better leverage the advantages of threaded connections and achieve long-term stable operation and efficient production of the equipment.
