SLETPETRO has been keeping up with the needs of customers, always providing customers with high-quality products and reducing operating costs. We started the R & D and production of swivel joints blanks in 2020. During this period, we invested a lot of equipment and materials to carry out various tests, and successfully mass produced swivel joints blank in May 2021. Our 3 "- 105 MPa swivel joints blanks can pass the ball 63.5mm, and the comprehensive performance fully meets the requirements. After two years of hard working, we have made a great breakthrough in swivel joints blank, so that we can better serve our customers.
