OCTG Casing and Tubing
OCTGCasing and Tubing
OCTG casing and tubing is widely used as tubes infurnaces and heat exchangers in oil refineries and seamless steel pipes. They areoften used in the manufacturing of both structural and mechanical parts, suchas drill pipes, automotive drive shafts, bicycle frames and steel scaffolding.Manufacturing ring shaped work pieces with a petroleum refining pipe improvesthe utilization and simplify the manufacturing process, as well as savematerials and time.
For example, steel tubes are widely used for producingbearing rings. Petroleum refining pipes are also indispensable materials for conventionalweapons such as gun barrels and cannon barrels. These refining pipes are dividedinto circular tubes and specialty tubes according to the number of differentcross section shapes. Because the circle has the largest area among all theshapes with the same perimeter, circular tubes are used to convey more fluid.
Tubing: OCTG casing and tubing is used for oilextraction, gas extraction, water injection and acid fracturing.
Casing: Casing is a pipe that is cemented to a drilledbore below the ground and used as a rigid wall to prevent the bore from collapsing.
Drill pipe: A pipe used for drilling holes
Line Pipe: This pipe is used to transport oil and gas.
Coupling: Coupling is a cylinder with an internalthread that connects two threaded pipes.
Coupling Material: Tubes are also used to manufacturecouplings.
API threads: The pipe threads specified in API 5B standardsinclude the knuckle threads of oil tubes, the short round thread of a casingpipe, the long round thread of a casing pipe, the buttress thread of a casingpipe, and the thread in a line pipe.
Premium connections: Premium connections are non APIthread connections featuring sealing properties, connecting properties andother advantageous properties.
