Demand for and Development of Hi-performance OCTG

Addressing the increasingly complicate and crucial service conditions,non-API OCTG with much higher performance have come to be developed. Proposals concerning R & D of hi-performance OCTG are made on the basis of an overall analysis of the changed service conditions for OCTG and a review of the production and development of hi-performance OCTG both at home and abroad,and consideration of demand for OCTG by domestic oil and gas exploration sector,including the primary agenda for basic research for application and the orientation for product type development.
