Also known as oil steel pipe is extracted from deep underground flammable viscous brown liquid. Mainly of alkanes, cycloalkanes, aromatic hydrocarbons mixture. It is the ancient seas or lakes of biological evolution through the formation of a mixture of long, as are fossil fuels and coal. Persian Gulf, a store with a rich, in Russia, the United States, China, South America also have a lot of storage. Primarily used as fuel oil and gasoline, but also many industrial products such as chemical solution, chemical fertilizers, pesticides and plastics raw materials.
Oil pipe (GB9948-88) is applied to the oil refinery furnace tubes, heat exchangers and pipe seamless steel pipe. Oil pipe is a hollow cross-section, no seams around the long bar of steel, oil cracking pipe is an economic cross-section steel.
Geological drilling steel (YB235-70) is a core drilling for geological department for the use of steel, use can be divided into the drill pipe, drill collar, core pipe, casing and precipitation tubes.
Oil drilling pipe (YB528-65) is used to thicken the oil drilling within or outside the thick ends of the seamless steel pipe. Steel sub-threading threading and not two, Threading Pipe Fittings links, not welded tubes threading methods and tool joints connected.
Widely used in the manufacture structural parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle frames and construction using steel scaffolding. Ring with petroleum cracking pipe manufacturing parts, can improve material utilization, simplify the manufacturing process, saving materials and processing man-hours, such as bearing rings, jack sets, etc., has been widely used to make steel. Oil cracking pipe, or a variety of conventional weapons indispensable material, barrel, barrel of oil cracking pipe and so have to make. Oil cracking tube by cross-sectional area can be divided into different shapes and tube shaped tube. Since the circumference of the same conditions, the largest oil cracking pipe, with a circular tube can transport more fluid.
