Titanium alloy tube cabin passing method for ship

Abstract

The invention discloses a titanium alloy tube cabin passing method for a ship. The method is used for a steel bulkhead or a deck with the water-tight and fire-proof requirements on the ship through the titanium alloy tube, wherein the cabin passing method is based on the following titanium alloy tube device; the following titanium alloy tube device comprises a titanium alloy tube, a steel outer frame body which is arranged on the titanium alloy tube in a sleeving manner, a fireproof packing which is filled between the steel outer frame and an interlayer formed by the titanium alloy tube and fireproof plugs are filled at the two ends of the interlayer; and the cabin passing method comprises the following steps that 1, a cabin penetrating position of the titanium alloy tube is determined according to a tube system installation diagram; 2, a cabin penetrating hole with a preset diameter is formed in the position, on the cabin wall or the deck, of the cabin penetrating hole; and 3, the steel outer frame body is fixed in the cabin penetrating hole. The titanium alloy tube cabin passing method has the beneficial effects that the situation that the titanium alloy tube is difficult to weldto steel so as to cause a real-ship application disorder is solved, so that the fireproof, smoke-proof and watertight separation of the two ends of a cabin penetrating part is realized.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to a method for passing a titanium alloy pipe through a ship for a ship. Background technique [0002] Titanium is an important structural metal developed in the 1950s. Titanium alloys have the characteristics of high strength, good corrosion resistance, and high heat resistance. Titanium alloy tubes are used in naval seawater piping systems or other systems. They have the characteristics of strong corrosion resistance and long life, and their application prospects are broad. [0003] At present, in view of the actual needs, the relevant departments are planning to gradually promote the application of titanium alloy pipelines on ships. [0004] Because titanium alloy materials and steel will react at high temperatures to form brittle compounds, which are extremely brittle and fractured, it is generally difficult to weld them together. Therefore, when titanium all...

[0004] Because titanium alloy materials and steel will react at high temperature to form brittle compounds, which are extremely brittle and fractured, it is generally difficult to weld together

Therefore, it is difficult for shipyards to directly use conventional doubler plates or reinforced casings when titanium alloy pipelines are pierced with steel bulkheads that require watertightness and fire protection.
