The following is a comparative analysis of the sliding support with the conventional elastic hanger in terms of design, procurement, construction, and the like.
Design cost
Design period
The design cycle of the elastic hanging bracket and the design cycle of the sliding support are basically the same and are two cycles.
Total number and arrangement difficulty
Taking the medium bulk 210K as an example, the elastic hanger can order 232 total orders for a single ship, and the sliding support single ship can order 107 total orders, so the arrangement difficulty is substantially equal.
Table 1 purchase cost calculation table for scattered 210K elastic hanger
Table 2 purchase cost calculation table for bulk 210K sliding support structure
Cost of purchase
As can be seen from tables 1 and 2, the number of the elastic hangers and the manufacturing period are about 2 times that of the sliding support, and the procurement cost of the elastic hangers is about 3 times that of the sliding support.
Construction cost
Construction period
According to field practical verification, for smoke exhaust pipes with the same size, the time required for welding one elastic hanging bracket is approximately the same as the time for welding a group of sliding supports, and the number of the group of elastic hanging brackets is approximately 2-6, so that the construction time of the sliding supports is about 1/2-1/6 of that of the elastic hanging brackets.
Difficulty of construction
Most of the sliding supports need flat welding and few of the sliding supports need overhead welding, so that the construction difficulty is greatly reduced.
In the design at the present stage, the support part which is slidably supported on the smoke exhaust pipe is prefabricated with the pipe to be supplied integrally, so that the high-altitude operation workshop is used, the construction difficulty is reduced, the construction quality is improved, and the field welding workload and the risk of pipe deformation are reduced.
Service life and reliability
The sliding support is made of steel plates, so that the service life is long, the sliding support is firm and reliable, and the sliding support does not need to be replaced in the later period.
The sliding support is self-made in a factory, the production and supply period is short, and the supply time is controllable.
Through above data acquisition and demonstration analysis, can see, no matter from aspects such as design cost, purchasing cost, supply of goods cycle, construction, the slip support all has stronger advantage, under the prerequisite of the equal design degree of difficulty, purchasing cost is lower, and supply of goods cycle is controllable, and the construction degree of difficulty is little, long service life, and the good reliability.
