In the working process of the screw pump, the rotor rotation will trigger the twisting and vibration of the oil pipe. In addition, the J-groove of the tubing junction is subject to high friction during the extraction process, which is where most of the tubing damage and deterioration problems occur. At the same time, operators […]
Petroleum casing is a large diameter tubing that serves to secure the wall or borehole of oil and gas wells. The casing is inserted into the borehole and secured with cement to prevent the borehole from separating the rock formation and collapsing, and to ensure the circulation of drilling mud to facilitate drilling and extraction.Steel […]
p110 oil casing as oil casing is an important equipment for oil drilling, to our industrial construction and other practical activities to bring many positive impact and role, so what in-depth understanding of its en, small editors small popularization for you. The basic introduction and performance analysis of p110 oil casing I. Introduction (1) The […]
There are many different materials of oil casing, basic carbon steel, J55, L80, P110 and other special materials such as 3 cr, 9 cr, 13 cr, 22 cr, etc., mainly carbon dioxide resistant and known as hydrogen sulfide resistant materials such as 90 SS, 95 ss, etc. In addition, higher grade and nichrome alloy pipes […]
The use of steel pipe to manufacture ring-shaped parts can improve the material utilization rate, simplify the manufacturing process, save materials and processing hours, such as rolling bearing collars, jackets, etc., and has been widely used to manufacture steel pipe. (1) The main importing countries of API oil casing are: Germany, Japan, Romania, Czech Republic, […]
Oil casing is a steel pipe used to support the well wall of oil and gas wells to ensure that the drilling process is carried out and that the entire well operates properly after completion. Several layers of casing are used in each well depending on the drilling depth and geological conditions. The casing is […]
Insulation joints are mainly used in the sealing protection of oil and gas pipelines and to prevent electrochemical corrosion. They are mainly composed of short joints, steel flanges, fixing rings, seals, insulation plates, insulation sleeves and filling insulation materials. Seals can be O-ring seal, U-ring seal and “O-shaped + U-shaped” composite seal, although the sealing structure […]
Generally speaking, the surface treatment of structural steel plates is needed to increase their anti-corrosion and durability. The quality of surface treatment directly affects the adhesion of the coating to the substrate of the coated workpiece and the corrosion resistance of the material. Oil, grease, dust and other contaminants will cause the paint film to fall off or […]
