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 have been looking for a “magic tool” that can improve the casing torque rating and reduce costs at the same time. With the DTR tool, casing connection is no longer a problem! DeltaTORQ Rings (DTR) is a new casing connection kit designed specifically for the upstream oil and gas industry to increase the torque load […]

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 main importing countries of petroleum casing are: Germany, Japan, Romania, Czech Republic, Italy, Britain, Austria, Switzerland, the United States, Argentina, Singapore are also imported. Import The standard mostly refers to the American Petroleum Institute standard API5A, 5AX, 5AC. steel grade is H-40, J-55, N-80, P-110, C-75, C-95, etc.. The specifications are mainly 139.77.72R-2, 177.89.19R-2, 244.58.94R-2, […]

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 cemented after the well is drilled, and unlike tubing and drill pipe, it is not reusable and is a one-time consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well tubing. Oil special pipe is mainly used for drilling of oil and gas wells and transmission of oil and […]

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 produce a variety of appearance defects, anticorrosive coating can improve the anticorrosive protection of the paint layer on the steel plate and the smooth surface of the base steel. Common anticorrosive coatings require a substrate surface cleanliness of SA2.5 or above, and steel plate surface coatings provide excellent corrosion protection for the water treatment industry, pulp […]
