Movable pipe structure, arrangement method and ship

Abstract

The invention discloses a movable pipe structure, an arrangement method and a ship. The movable pipe structure comprises a firs connecting part, a second connecting part and a fastening piece; the first connecting part comprises a through pipe and a first flange; the second connecting part comprises a movable pipe, a gland and a sealing filler; the outer diameter of the movable pipe is smaller than the inner diameter of the through pipe; one end of the movable pipe is positioned in the through pipe; the gland is provided with a limiting groove; the sealing filler is arranged in the limiting groove, and is bonded with the outer wall of the movable pipe; a fixed hole is formed in the gland; and the gland and the first flange are fixedly connected by the fastening piece. In the movable pipe structure, the end, with the smaller pipe diameter, of the movable pipe is arranged in the through pipe with the larger pipe diameter; and through relative movement between the movable pipe and the sealing filler, the extension function is achieved to a certain extent, so that single arrangement of an extension joint is not needed, the pipe structure is simplified, and the pipe cost and the maintenance difficulty are reduced.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a movable pipeline structure, a setting method and a ship. Background technique [0002] When a ship is sailing at sea, the hull structure will undergo a certain degree of elastic deformation due to the extrusion of sea water or the impact of waves in the water. In addition, the hull structure will also undergo a certain degree of deformation due to thermal expansion and contraction under different temperature environments. Due to the difference in strength and thermal expansion rate between the pipeline installed on the ship and the hull structure, there is a certain difference in the deformation between the hull structure and the pipeline in the complex marine environment. [0003] The piping system of the bilge water and ballast water at the bottom of the ship needs to penetrate multiple watertight panels in the forward and backward direction along the length of the ship...

Problems solved by technology

However, this kind of movable pipeline structure makes the pipeline and the watertight bulkhead fixedly welded. When there is a difference in the deformation between the pipeline and the hull structure, this deformation difference will be reflected between the pipeline and the hull structure in the form of tensile stress. The existence of this stress easily leads to the deformation of the hull structure or the leakage of the pipeline
