Universal ethylene cracking furnace coil pipe hanging test tool and test method

Abstract

The invention discloses a universal ethylene cracking furnace coil pipe hanging test tool which comprises a main hanging beam and universal hanging rings. The lower part of the main hanging beam is connected with a plurality of universal hanging rings, and the lower parts of the universal hanging rings are connected with a UU-shaped turnbuckle; the top of one end of a coil pipe is connected with the UU-shaped turnbuckle through a lifting rod assembly of a pipe taking the shape of the Chinese character bo, and the top of the other end of the coil pipe is connected with the UU-shaped turnbucklethrough a middle connecting piece; and an auxiliary tool is arranged at the lower part of the coil pipe. The universal ethylene cracking furnace coil pipe hanging test tool is reasonable in structure,convenient and simple to operate and wide in application range, the cost and the space for storing hanging test tools are greatly reduced, the service life is prolonged, the labor force is greatly saved, and the testing accuracy is improved.

Description

Technical field[0001]The invention relates to the field of ethylene cracking furnaces in the petrochemical industry, in particular to a universal ethylene cracking furnace coil hanging tool and 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 unit. 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 The equipment is 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, and each sub-panel is assembled and welded with a special welding tool for fixing the distance between the coil tubes and the tubes. When the coil is transported to the customer's site for installation, the coil assembly welding tooling will be removed. ...

AI Technical Summary

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.
