Problems solved by technology

When installing platform components in the segment stage, a large amount of manpower and material resources are required for precision adjustment in the segment stage, and the assembly time of the segment is longer. After closing, a second adjustment is required for positioning, which increases the segment construction cycle and affects construction efficiency.

Embodiment Construction

[0032] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0033] A duplex stainless steel mediastinal compartment manufacturing process, such as Figure 1-4 As shown, the duplex stainless steel medial compartment is divided into the first longitudinal wall segment and the second longitudinal wall segment to be constructed separately. After the first longitudinal wall segment is completed, the second longitudinal wall segment is constructed. The two construction methods are the same. The completed first vertical wall segment is turned over 180° and mounted on the second vertical wall segment, and then the first vertical wall segment and the second vertical wall segment are turned over 180° as a whole, and the first vertical wall segment is turned over 180° After loading and closing on the second longitudinal wall segment, evenly arrange some weights on the first longitudinal wall segment to reduce welding defor...

Abstract

The invention relates to a segmental manufacturing process for a duplex stainless steel medial compartment, comprising a first longitudinal wall segment and a second longitudinal wall segment, the first longitudinal wall segment and the second longitudinal wall segment are constructed separately, and then the first longitudinal wall segment is turned over 180° loading and closing on the second vertical wall segment, and then the first vertical wall segment and the second vertical wall segment are turned over 180° as a whole. According to the invention, the marking and inspection work of the segmented liquid cargo tank surface is constructed separately according to the first longitudinal wall segment and the second longitudinal wall segment, so as to reduce the number of segmental turnovers and improve segmental construction efficiency.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a segmental manufacturing process for a duplex stainless steel medial compartment. Background technique [0002] In the process of ship segmental construction, both sides of the mediastinal tank segments of chemical tankers are duplex stainless steel bulkheads. During construction, one side is usually used as the base surface to make segments. After completion, they are turned over and closed to form segments. When installing platform components in the segment stage, a large amount of manpower and material resources are required for precision adjustment in the segment stage, and the assembly time of the segment is longer. After closing, a second adjustment is required for positioning, which increases the segment construction cycle and affects construction efficiency. [0003] The main reason for this situation is that the requirements in the production stage of the parts are not high,...
