Problems in processing pipe threads per GB7306.1

2021-10-09View Original

Thread Content

The pipe sizes to which this standard applies should be American standard pipes; therefore, can pipes of Series II (DN15~50) be threaded in accordance with this standard? How is the sealing?

According to the specifications, it is a 55-degree cylindrical pipe thread; there is no 60-degree version with better sealing performance.
