Oil well pipes, also known as oil special pipes, are the foundation of the petroleum industry. Casings, tubing and drill string components (drilling rods, drill collars, kelly bars, etc.) are collectively referred to as oil well pipes (OCTG for sale).
Seamless casing pipe for oil well drilling is inserted into a well bore and cemented in place to protect both subsurface formations and the well bore from collapsing and to allow drilling fluid to circulate and extraction to take place.
The cost of casing is a major part of the overall well cost, so selection of casing size, grade, connectors, and setting depth is a primary engineering and economic consideration. Saigao can manufacture and supply API 5CT standard casing pipe with good quality and competitive price.
