High pressure seamless steel pipe related professional ability - high pressure heat treatment equipment seamless steel pipe: it is very important to produce high-quality carbon steel, alloy tool steel, rusty steel plate seamless steel pipes for high pressure and upper gas steam boiler pipes. Under the action of high-temperature flue gas and steam, boiler tubes working under high temperature and pressure will cause air oxidation and corrosion.
The selected steel models include: high-quality carbon steel models and specifications of 40g, 50mng and 25mng; Alloy tool steels are 15 megaohms, 50 megaohms, 12 carats, 15 carats, etc. In addition to ensuring the composition and use performance, it must also be constrained one by one, and must be flared and flattened. Seamless steel pipes are provided by heat treatment process. In addition, the microstructure, grain size and nitriding layer of seamless steel pipe are also specified.
Seamless steel pipes for landform exploration and crude oil exploration and processing; In order to better understand the underground rock structure, surface water, crude oil, natural gas and ecological environment, drilling rigs are used for exploration. Drilling is indispensable to the exploitation of crude oil and natural gas. Geomorphologic exploration and manipulation of seamless steel pipes for petroleum exploration are the key mechanical equipment for exploration, including rock sample outer pipe, rock sample connecting pipe, soft flexible waterproof casing, drilling equipment, etc. Because all aspects of the exploration pipe must work in the geological structure thousands of meters deep, and the working system is extremely complex, the drilling machinery and equipment must bear such stress fields as stretching, shrinking, bending, deformation, and unbalanced failure load., It also suffers from the destruction of cement mortar and rock layer. Therefore, the pipe fittings are required to have sufficient compressive strength, tensile strength, wear resistance and fracture toughness as far as possible.
Stainless steel pipe: various types of hot-rolled and cold-rolled stainless steel pipes are widely used in the pipelines and stainless steel parts of mechanical equipment in various application fields of petrochemical enterprises. In addition to ensuring the composition and service performance, the pressure seamless steel pipe shall also be guaranteed according to the AC pressure test. Various unique seamless steel pipes shall be guaranteed as required.
