Abstract

The invention discloses an installation method of an oil compartment steam heating coil pipe used for a ship. After the segmenting forming is carried out to the oil compartment, the oil compartment steam heating coil pipe is started to be installed; then the position of a pipe bracket is determined according to the installation coordinate of the oil compartment steam heating coil pipe in a drawing, and the pipe bracket is installed on a special large angle bar for the oil compartment steam heating coil pipe to be preassembled; then a first oil compartment steam heating coil pipe is fixed on the pipe bracket according to the installation coordinate in the drawing, then one end of the second oil compartment steam heating coil pipe is inserted into the connecting sleeve of the first oil compartment steam heating coil pipe and the second oil compartment steam heating coil pipe is fixed on the pipe bracket according to the coordinate, the positioned and installed oil compartment steam heating coil pipes are fixed on the connecting piece of the connecting sleeve by dot welding, and the other oil compartment steam heating coil pipes are installed in sequence; and finally the pipe bracketand the connecting sleeve are welded. The installation method has the advantages of regular and artistic appearance, convenient installation and inspection, environmental protection, and good economic benefit.

Description

technical field [0001] The invention relates to a method for installing steam heating coils in oil tanks, in particular to a method for installing steam heating coils in marine oil tanks. The utility model belongs to the field of installation of oil tank heating coils. Background technique [0002] In the past, steam heating coils for oil tanks were installed on the berth / dock, and there were more than 200 heating pipes of five to six hundred meters in total in the four large tanks. Due to the airtight and narrow cabin, the working environment and conditions of front-line workers are extremely poor. A large number of bushings and pipe brackets are welded in the airtight cabin. In addition, due to the many cross operations on board, the small space, and the harsh environment for operation and inspection, not only the safety hazard is great, but also the tightness process cycle is long, and the inspection link lags behind. According to statistics, under this old installation...
