oil casing pipe

high quality API 5CT casing and tubing for oil and gas drillings

Steel casing is kind of pipe that normally runs underground. It can be utilized to protect items inside the pipeline or to provide an additional barrier between the matter in the pipeline and the earth. Another name for these products is encasement pipelines. The pipes are typically placed in the ground in separate sectors and then bonded together. In some cases, pipeline can be threaded through a pre-existing hole or tunnel. The latter technique is generally needed since the hole was drilled, instead of dug from ground level, due to an obstruction such as a roadway or a river. Tubing […]

n80 oil casing seamless steel pipe

API 5CT N80 Oil and Gas Casing Pipe, OD 177.8mm,WT9.19mm casing tube

The N80 oil and gas API casing pipe includes N80-1 and N80-Q types. These 2 products are consistent in the chemical structure and mechanical residential or commercial properties, and are simply different in the heat treatment. This type of item is commonly utilized in the oil drilling process. As its mechanical homes are greater than J55 and K55 types, it can be used to some a little more complex developments. With much deeper downhole depth than J55 and K55 types, it can be utilized for the exploitation of middle-level oil and gas. Due to the high efficiency of N80 material, […]

API 5CT /5B seamless Casing and tubing, K55, OD 4 1/2″ STC oil and gas pipeline

Tube for conveying gas, water, and oil in both and natural gas industries etc. Casing:Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore.It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place. Steel Casing Pipes have smooth wall & minimum yield strength of 35,000 psi. Tubing: Tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer […]
