Product Description
High-pressure Corrosion-Resistant Carbon Steel Seamless Steel PipeOil Casing / Galvanized Seamless Steel Tube / Line Pipe / Petroleum Cracking Seamless Steel Pipe / Special fertilizer pipe
1. Oil Casing: The oil casing is used to support the oil and gas well walls to ensure the normal operation of the entire well after the drilling process is completed. Each well is based on different depths of drilling and geology, using several layers of casing. After the casing is down, the cement is to be cemented. It is different from the oil pipe and the drill pipe and cannot be reused. It is a disposable material. Therefore, the consumption of casing accounts for more than 70% of all oil well pipes. Casing can be divided into: conduit, surface casing, technical casing and oil casing.
The oil special pipe is mainly used for drilling oil and gas wells and conveying oil and gas. It includes oil drill pipes, oil casings, and oil pipes. Oil drill pipes are mainly used to connect drill collars and drill bits and transmit drilling power. The oil casing is mainly used for supporting the well wall during and after the completion of the drilling process to ensure the drilling process and the normal operation of the entire well after completion. The oil pipe mainly transports the oil and gas at the bottom of the oil well to the ground.
Oil casing is the lifeline for maintaining oil well operations. Due to different geological conditions, the state of the downhole is complicated, and the combined action of tension, compression, bending and torsion stress acts on the pipe body, which puts high requirements on the quality of the casing itself. Once the casing itself is damaged for some reason, it may result in a reduction in production and even scrapping of the entire well. According to the strength of the steel itself, the casing can be divided into different steel grades, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150 and so on. The well conditions and well depth are different, and the steel grades used are also different. The casing itself is also required to have corrosion resistance in a corrosive environment. It is also required that the casing has anti-crushing properties in places with complicated geological conditions.

2. Galvanized Seamless Steel Tubes:Galvanized seamless steel tubes have very little galvanizing, only 10-50g/m2, and their corrosion resistance is much worse than that of hot-dip galvanized pipes. Regular galvanized pipe manufacturers use quenched galvanized pipes as water and gas pipes. The galvanized layer of the cold-galvanized steel pipe is an electroplated layer, and the zinc layer and the steel pipe base are separately layered. The zinc layer is thin, and the zinc layer is simply attached to the steel pipe base and is easy to fall off. Therefore, its corrosion resistance is poor. In newly built houses, the use of cold-galvanized steel pipes as feedwater pipes is prohibited. After pickling, it is washed by a solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride. In order to ensure quality, electrogalvanizing (cold plating) is often not used. Only small companies with small equipment and old equipment use electro-galvanized steel, of course, their prices are relatively cheaper. At present, the Ministry of Construction has officially laid down the cold-galvanized pipe with backward technology, and it will not be electro-galvanized in the future. The molten metal is reacted with an iron matrix to produce an alloy layer, thereby combining the matrix and the plating. Hot-dip galvanizing is to pickle the steel pipe first, in order to remove the iron oxide on the surface of the steel pipe, and then feed it into the hot dip plating tank. Hot-dip galvanizing has the advantages of uniform plating, strong adhesion and long service life.
3. Line pipe:API SPEC 5L-2011 (Line Pipe Specification), compiled and published by the American Petroleum Institute, is used worldwide. The main material of the tube is steel grades such as L245, L290, L360, L415, L480, GR.B, X42, X46, X56, X65, X70, X80 and X100.
According to the performance requirements of GB/T9711.1 pipeline steel pipe, depending on the tempering temperature, tempering can be divided into the following types:
[1] Low temperature tempering (150-250 degrees)
The structure obtained by low temperature tempering is tempered martensite. The purpose is to reduce the internal stress and brittleness of the quenched steel under the premise of maintaining the high hardness and high wear resistance of the quenched steel, so as to avoid cracking or premature failure during use. It is mainly used for all kinds of high carbon cutting tools, measuring tools, GB/T9711.1 pipeline steel pipe, rolling bearings and carburizing parts, etc., the hardness after tempering is generally HRC58-64.
[two] medium temperature tempering (250-500 degrees)
The tissue obtained by medium temperature tempering is tempered troostite. Its purpose is to achieve high yield strength, elastic limit and high toughness. Therefore, it is mainly used for the treatment of various GB/T9711.1 pipeline steel pipes and hot work dies. The hardness after tempering is generally HRC35-50.
[three] high temperature tempering (500-650 degrees)
The structure obtained by high temperature tempering is tempered sorbite. Conventionally, the heat treatment combined with quenching and high temperature tempering is called quenching and tempering treatment, and the purpose is to obtain comprehensive mechanical properties with good strength, hardness, plasticity and toughness. Therefore, it is widely used in important structural parts such as automobiles, GB/T9711.1 pipeline steel pipes, machine tools, etc., such as connecting rods, bolts, gears and shafts. After tempering, the hardness is generally HB200-330.
Product specifications range: outer diameter 95mm-426mm; wall thickness 4.5mm-60mm
4. Petroleum Cracking Seamless Steel Pipe:The petroleum cracking seamless steel pipe is a long steel with a hollow section and no joints around, and the petroleum cracking pipe is an economical section steel. Widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automotive drive shafts, bicycle frames and steel scaffolding used in construction. The use of petroleum cracking tubes to manufacture ring-shaped parts can improve material utilization, simplify manufacturing processes, save materials and processing man-hours, such as rolling bearing rings, jack sleeves, etc., and have been widely used in steel pipes. Petroleum cracking tubes are also indispensable materials for various conventional weapons. Gun barrels and barrels must be made of petroleum cracking tubes. Petroleum cracking tubes can be divided into round tubes and shaped tubes according to the shape of the cross-sectional area. Since the area of the petroleum cracking tube is the largest under the condition of equal circumference, more fluid can be transported by the circular tube.
5. Special Fertilizer Pipe:Special fertilizer pipe GB6479-2000 refers to seamless steel pipe for high pressure fertilizer equipment. It is mainly used to transport high temperature and high pressure fluid pipelines on fertilizer equipment. Representative materials are 20, 16Mn, 12CrMo, 12Cr2Mo and the like. Applicable environment
