13 3/8'' Casing Pipe

Oil casings can be roughly classified into surface casings according to different ways of use. Intermediate casing. Production of casing. Drilling casing. The surface casing is mainly: the casing of the subsequent layers is suspended and supported by a casing head mounted at the top. Napo long round buckle N80 oil casing professional The company provides you with high quality spiral steel pipe with diameter ranging from 219mm to 3820mm and thickness from 5mm to 25mm. Material Q235B, Q345B, etc. can produce welding of various specifications, materials and shapes according to your requirements. 


The standard hydraulic pressure test pressure of the oil casing is calculated according to the downhole. This puts high demands on the quality of the casing itself. Once the casing itself is damaged for some reason, it may result in a reduction in production and even scrapping of the entire well. According to the strength of the steel itself, the casing can be divided into different steel grades, namely JKNLCTPQV150. The well conditions and well depth are different, and the steel grades used are also different. The casing itself is also required to have corrosion resistance in a corrosive environment. It is also required that the casing has anti-crushing properties in places with complicated geological conditions.


Applications of 13 3/8'' Casing Pipe:

API 5CT casing 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 supply API 5CT standard casing pipe with assured quality and competitive price.Your honored customers' need is our goal to work for with our best efforts!
