Problems solved by technology

Without the limitation of assembly welding equipment, there may be a large center distance deviation between the pipe fittings in the ethylene cracking furnace coil, and there may be mutual interference between the bottom S pipe and the U pipe. In the process of use, there will be uneven heating, which will cause the coil to be twisted, and in severe cases, the pipe section will break, which will greatly affect the service life of the ethylene cracking furnace coil.

Abstract

The invention discloses a general-purpose ethylene cracking furnace coil hanging test tool, which includes a main suspension beam and a universal suspension ring. Several universal suspension rings are connected to the lower part of the main suspension beam, and UU-shaped turnbuckle screws are connected to the lower part of the universal suspension ring; The top of one end of the coil is connected to the UU-shaped turnbuckle through a bu-shaped pipe lifting rod tooling, and the top of the other end of the coil is connected to the UU-shaped turnbuckle through an intermediate connector; the lower part of the coil is provided with auxiliary tooling. The invention has the advantages of reasonable structure, convenient and simple operation, wide application range, greatly reduced cost and storage space for hanging test tooling, prolonged service life, greatly reduced labor force, and improved inspection accuracy.

Description

technical field [0001] The invention relates to the field of ethylene cracking furnaces in the petrochemical industry, in particular to a general-purpose ethylene cracking furnace coil hanging tool and a test method. Background technique [0002] Ethylene is the core of the petrochemical industry. The ethylene cracking furnace coil is the core equipment of the ethylene production plant. Its main function is to process various raw materials such as natural gas, refinery gas, crude oil and naphtha into cracked gas, and provide it to other ethylene device, and finally processed into various products such as ethylene and propylene. When the ethylene cracking furnace coil is produced by the manufacturer, a furnace is divided into several sub-panels. When each sub-panel is assembled and welded, there is a welding tool for fixing the distance between the coil tubes and the tubes. When the coil is transported to the customer site for installation, the coil welding tool will be remo...
