Embodiment Construction

[0014] The present invention is described in further detail below in conjunction with accompanying drawing:

[0015] Such as figure 2 As shown, in the smoke exhaust pipe opening method of the present invention, the components used include the opening steel pipe 1, double plate 2, cylindrical coaming 4, seat plate 5, gasket 6, heat insulation pad 7, bolt heat insulation sleeve 8. Bolt heat insulation pad 9, bolt 10 and flanges 11 at both ends of the steel pipe through the cabin. The open cabin steel pipe 1 is a short pipe that needs to pass through the bulkhead 3 in the smoke exhaust pipeline; the double plate 2 is an annular steel plate welded on the open cabin steel pipe 1; the cylindrical coaming 4 is welded around the opening of the bulkhead 3 The reinforcement plate can be a steel pipe or rolled with a steel plate; the seat plate 5 is an annular plate welded on the end of the cylindrical coaming plate 4, which can be cut with a steel plate or a standard flange can be sel...

Abstract

The invention discloses a smoke exhaust pipe penetration method, and relates to the technical field of ship pipeline design and installation. The related parts in the method comprises a penetration steel pipe, a compound plate, a surrounding plate, a seat board, a gland bush, an insulating pad, a bolt insulating sleeve, a bolt insulating pad, a bolt and flanges. The method comprises: one end of the surrounding plate is welded with the seat board, and the other end thereof passes through an open pore of the bulkhead and is welded with the bulkhead; the compound plate is welded on the penetration steel pipe, the flanges are welded at the two ends of the penetration steel pipe, the gland bush, the insulating pad, the bolt insulating sleeve and the bolt insulating pad are sheathed on the bolt,and the compound plate is connected with the seat board by the bolt. The penetration method not only meets the water tight and fire-proof requirements of a penetration piece, but also avoids the heatof the pipeline being transmitted towards the bulkhead of the ship.

Description

technical field [0001] The invention relates to the technical field of ship pipeline design and installation, in particular to a method for opening a smoke exhaust pipe into a cabin. Background technique [0002] At present, in the process of ship pipeline design and installation, there are no relevant national standards and industry standards for the type of smoke exhaust pipeline, and each shipyard designs and builds according to their own habits. Some shipyards do not even consider the heat transfer of the bulkhead, and directly adopt the common type of steel pipe through the tank, that is, the doubler plate of the through tank is directly welded to the bulkhead; High temperature gaskets (graphite gaskets), such as figure 1 As shown, the components involved in the smoke exhaust pipe opening method include the opening steel pipe 1, the doubler plate 2, the heat insulation pad 7, the bolt insulation sleeve 8, the bolt heat insulation pad 9, the bolt 10 and the flanges at b...
