The Production of the seamless steel tube Can Reflect the Quality and Efficient
Seamless steel pipe production can reflect the advantages of high quality and efficiency.
(firmenpresse) - A seamless steel pipe unit output equivalent to 5-8 sets of oil casing equipment, how to make more than one coil production line equipment can achieve uniform production standards, that is, according to the same production process and quality assurance system to meet production standards Welding quality requirements and pipe manufacturing grade will be a heavy task.
The production of seamless steel tubes is a continuous process that is basically uninterrupted under a uniform operating condition: the straight seam welded pipe production process is segmented, including the entire plate / indenter / pre-roll / spot welding / welding / finishing / group reciprocal process. This is the production of seamless steel pipe production is different from the important characteristics of oil casing. The length of the pipe in the delivery line is proportional to the length of the pipe, the viscosity of the fluid, the velocity of the fluid, the resistance coefficient of the fluid, and is inversely proportional to the inner diameter of the pipe. And the fluid resistance coefficient is related to the Reynolds number and the roughness of the inner wall surface of the pipe.
It is determined that the effect of the roughness of the inner wall surface of the pipe is ten times greater than that of the localized area (such as a spiral weld or a long weld, even an inner ring weld). The field of solderability is mainly determined by the pipe material and port size tolerance with the decision. Taking into account the requirements of the installation of steel pipe, steel pipe production and continuity of the shape of the geometric size of the consistency is particularly important. The chaos of the production conditions is very easy to weld quality control and geometric dimensions of the guarantee.
Because the seamless steel pipe tube regular, the average distribution of weld, relative to the straight seam welded pipe, spiral steel pipe has a very good oval and the vertical face, to ensure that the field of steel pipe group on the group when the accuracy. According to the determination results, the fatigue strength of the seamless steel pipe is the same as that of the seamless pipe and the resistance pipe, and the test data are in the unified area with the seamless pipe and the resistance pipe, and higher than the ordinary submerged arc welded pipe. Increased production ratio of project management and quality monitoring. The differences in handling skills, quality awareness, distribution points and control procedures of the multi-oil casing unit and the corresponding welding equipment will bring about a lot of problems in production management, planned progress, inspection and acceptance, delivery coordination and so on. , Can easily lead to governance and coordination on the fuss and the quality of manufacturers and construction units prevarication.
Pipeline development trend is large caliber, high strength. With the increase in the diameter of steel, the use of steel-grade progress, resulting in ductile fracture tip stability of the greater trend of expansion. According to the US research institutions of the test shows that seamless steel pipe and oil casing is the same as a level, but the seamless steel pipe has a high impact toughness. Transmission pipeline because of the change in volume, in the actual operation process, the steel is subject to random alternating load. Understanding the low cycle fatigue strength of the steel pipe, to determine the useful life of the pipeline is of great significance.
