Siam Steel Pipe Company Limited focus on research and development of OCTG products with premium connections to meet the challenges presented in drilling operations. SGT is a new connection of our company which was born out of an exhaustive research and development program based on many years of field experience. We adopted the advantages of many famous connections such as HSC, VAM, NEWVAM etc when we design our own so the property of SGT is close to these products. And the significant features of SGT are that it can interchange with HSC, VAM and NEWVAM.
