Petroleum pipe is a seamless pipe suitable for furnace tubes, heat exchangers and pipes in petroleum refineries. Petroleum pipe is a long strip of steel with a hollow section and no joints around it, and petroleum cracking pipe is an economical cross-section steel.
It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding used in building construction mobile pictures, etc. Using petroleum cracking pipes to manufacture ring parts can improve material utilization, simplify manufacturing processes, save materials and processing man-hours, such as rolling bearing rings, jack sets, etc., have been widely used in steel pipes. Oil cracking tubes are also an indispensable material for various conventional weapons, and barrels, barrels, etc. must be made of oil cracking tubes. Petroleum cracking pipes can be divided into round pipes and special-shaped pipes according to the shape of the cross-sectional area. Due to the condition that the circumference is equal, the oil cracking tube has the largest area, and more fluids can be transported with circular tubes.
Structure of oil pipe
1.OCTG pipe: It is the abbreviation of Oil Country Tubular Goods, including finished oil casing, drill pipe, drill collar, coupling, short connection, etc.
2. Oil pipe: pipes used in oil wells for oil recovery, gas recovery, water injection and acid fracturing.
3. Casing: A pipe that is lowered from the ground surface into the drilled hole as a lining to prevent the wall from collapsing.
4. Drill pipe: a pipe used to drill a wellbore.
5. Line pipe: a pipe used to transport oil and gas.
6. Coupling: used to connect two threaded pipes and a cylindrical body with internal threads.
7. Coupling material: pipes used to make couplings.
8. API thread: pipe thread specified in API 5B standard, including oil pipe round thread, casing short round thread, casing long round thread, casing partial trapezoidal thread, line pipe thread, etc.
9. Special buckle: Non-API threaded buckle type with special sealing performance, connection performance and other properties.
Oil casing failure
The phenomenon of deformation, fracture, surface damage and loss of original function under specific service conditions. The main forms of oil casing failure are: collapse, slippage, rupture, leakage, corrosion, adhesion, wear and so on.
