Description
Technical field
The invention belongs to LNG ship oceangoing ship building technology fields, and in particular to a kind of dedicated multi-joint cryotronl crossing cabin part of LNG ship.
Background technique
In the prior art, during LNG ship designs, more cryogenic pipes is often had and are pierced by cargo Machine Room, and
And these pipelines, at a distance of relatively closely, the method that cryotronl is pierced by bulkhead is a main points of LNG ship design.Conventional way is in cabin
Direct aperture is passed through for cryotronl on wall, is welded and fixed between cryotronl and bulkhead by annular compound plate, due to the temperature of cryotronl
Very low, meeting bursting by freezing bulkhead is spent, therefore, the bulkhead of the bulk zone around annular compound plate cannot use carbon steel, but use low temperature
Stainless steel replaces.
In conclusion the design of the prior art mainly has following deficiency: (1) material cost of low temperature stainless steel bulkhead is high,
Increase the manufacturing cost of LNG ship；(2) when stainless steel bulkhead is with the butt welding of carbon steel bulkhead, difficulty is high, and time-consuming；(3) bulkhead aperture
Small, positioning to pipeline and through more demanding, site operation difficulty is big, while being also unfavorable for the cladding of exterior insulation.
Summary of the invention
