1. Product Name:API 5CT OCTG Casing Tubing

2. Product Description:Our OCTG casing and tubing are - · Tight tolerances · Consistent Roundness · Consistent Straightness · Weldable · Reliable High Steel Quality Sizes: Outside Diameter: 1.660? – 30? Grades: H40, J55, K55, N80,N80Q, L80, C90, C95, T95, P110, Q125,SS95,SS110, 9%CR, 13%CR 27MnCrV is a new type of steel for the production of TP110T steel-grade petroleum tubing sleeves. The steel grades for the conventional production of TP110T steel-grade petroleum tubing sleeves are 29CrMo44 and 26CrMo4.Compared with the latter two, 27MnCrV contains fewer Mo elements, which can greatly reduce the production cost.However, 27MnCrV produced by normal austenitic quenching process has obvious high temperature temper brittleness, resulting in low impact toughness and instability. Two methods are usually used to solve this kind of problem: one is to adopt the method of rapid cooling after tempering to avoid high temperature brittleness and obtain toughness.The second method is to improve the toughness of harmful elements and impurities by incomplete austenitization of steel.The first method, the heat treatment equipment requirements are relatively strict, need to add additional costs. 27 MNCRV steel AC1 = 736 ?, AC3 = 810 ?, the temperature quenching heating temperature when choosing between 740-810 ?.The selected temperature quenching heating temperature 780 ?, quenching heating heat preservation time of 15 min.After quenching tempering temperature 630 ?, tempering heat holding time 50 min.As the mild quenching is heated in the + two-phase region, the quenching is carried out in the state of retaining part of the undissolved ferrite, and the toughness is improved while maintaining a high strength. At the same time, the low temperature quenching is lower than the conventional temperature, which reduces the stress of quenching and thus reduces the deformation of quenching. In this way, the smooth operation of heat treatment production is guaranteed, and good raw materials are provided for the subsequent turning process. This process has been applied in the pipe processing plant of tianjin steel pipe group. The quality assurance data show that the yield strength Rt0.6 of the steel pipe after heat treatment is 820-860mpa, the tensile strength Rm is 910-940mpa, the impact toughness Akv is 65-85j, and the damage resistance is 100% qualified.The data show that 27MnCrV steel pipe is a high quality petroleum casing pipe of high steel grade. On the other hand, it also shows that the mild tempering quenching process is an excellent method to avoid high temperature brittleness in the production of steel products.
