Problems solved by technology

However, since the cylinder pipes in nuclear island equipment and pressure vessels are longer and larger than other ordinary pipes, there are certain errors in the above two methods, and the marking process is complicated, which requires more ability of marking personnel. High, ordinary welding workers cannot accurately and effectively draw the four centerlines of the pipe

Abstract

The invention relates to a long-barrel pipeline four-center-line scribing device and method. The scribing device comprises a reference support (1), supporting legs (2) and a gradienter (3); wherein the reference support (1) comprises a reference base (11) and a base handle (12); and the gradienter (3) is arranged at the top of the base handle (12), and the supporting legs (2) are connected with the reference base (11). The scribing device provide by the invention is ingenious in design, high in practicability, easy to manufacture and low in cost, the scribing method is convenient to operate and high in working efficiency, four center lines of a long-barrel pipeline can be accurately scribed even by non-professional scribing personnel, the professional operation difficulty is reduced, and operation is convenient.

Description

technical field [0001] The invention relates to a device and method for marking the four centerlines of long cylindrical pipes, especially long cylindrical pipes in the manufacturing process of nuclear island equipment and pressure vessels, and specifically relates to two long cylindrical pipes in the manufacturing process of nuclear island equipment and pressure vessels. Draw four centerlines at the end. Background technique [0002] "Hualong One" is a nuclear power research, design, manufacture, construction and operation of China's two major nuclear power companies, China National Nuclear Corporation (CNN, CNNC) and China General Nuclear Power Group (CGN, CGN) for more than 30 years. On the basis of experience, according to the experience feedback of the Fukushima nuclear accident and the latest safety requirements of my country and the world, the advanced mega-kilowatt pressurized water reactor nuclear power technology has been developed. [0003] As the main brand of Ch...
