OCTG, all named Oil CountryTubular Goods, tubular Goods for petroleum.The term refers to a class of steel tubes, mostly seamless, that are used exclusively for oil and gas production, but a significant proportion are welded.


The standard api-5ct drill pipe is the pipe connecting the drilling motor and the drill bit during drilling. The outer diameter is generally 2-6.5 inches (50-165mm) and the length is generally 5-14m.The casing serves as the structural wall or lining of the oil/gas well to prevent contamination of the well or surrounding groundwater, up to 26 inches in diameter.Casing accounts for more than 3/4 of shipments of dedicated petroleum pipes.


The working principle 


Drilling fluid flows through the drill string to the drill bit to cool the bit, while the resulting debris of soil and rock forms mud with the drilling fluid, which is transported to the surface through the annulus (the gap between the casing and the drill string).The drill string is mostly seamless because of the harsh working environment.oil casing


Petroleum pipe (gb9948-88) is suitable for furnace tube, heat exchanger and seamless pipe in petroleum refinery.The steel pipe for geological drilling (yb235-70) is the steel pipe for the geological department to conduct core drilling, which can be divided into drill pipe, drill collar, core pipe, casing pipe and sedimentation pipe, etc.Petroleum cracking pipe is a kind of strip steel with hollow section and no joints around.


Widely used in the manufacture of structural parts and mechanical parts, such as oil drilling pipe, car shaft, bicycle frame and construction moving pictures of steel scaffolding and so on.Using petroleum cracking pipe to make annular parts can improve material utilization and simplifyManufacturing process, material saving and processing time, such as rolling bearing ring, jack sleeve, etc., has been widely used to manufacture steel pipe.Oil cracking pipe is also an indispensable material for all kinds of conventional weapons.The oil cracking pipe can be divided into circular pipe and abnormal pipe according to the different shape of cross-sectional area.Since the area of the oil cracking pipe is the largest under the condition of equal perimeter, more fluid can be transported through the circular pipe.
