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 bracket and 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 a steam heating coil in an oil tank, in particular to a method for installing a steam heating coil in a marine oil tank. It belongs to the field of oil tank heating coil installation. Background technique [0002] In the past, the steam heating coils for oil tanks were installed on the slipway / dock, and there were more than 200 heating pipes of 500 to 600 meters in the four large cabins. Due to the tightness and narrowness of the cabin, the working environment and conditions of the frontline workers are extremely poor. A large number of casings and pipe brackets are welded in the enclosed cabin. The installation quality is difficult to guarantee, and there are also quality accidents such as heating coil leakage and warranty. In addition, due to the many cross operations on the ship, the narrow space, and the harsh operating and inspection environment, not only the safety hazards are large, but also the tightn...
