The invention provides a horizontal heat exchanger pipe bundle installing method, and relates to the field of heat exchanger installing. The method comprises the following steps that construction preparing is conducted, cranes are arranged in front of a heat exchanger barrel, and chain blocks are fixed to the positions above the heat exchanger barrel; the cranes are used for hoisting a pipe bundleto the position right in front of the barrel, and the center direction of the pipe bundle is consistent to the center direction of the barrel; the chain blocks are connected with the pipe bundle, andthe chain blocks and the cranes are matched to maintain stability of the pipe bundle; and a forklift is started to push the pipe bundle in the direction of the barrel, and pipe bundle installation isachieved. Through cooperation of the chain blocks and the cranes, the pipe bundle can be pushed without extension of the cranes to the position below the outward extending position of a second-floorplatform, the connecting positions of the chain blocks and the pipe bundle are constantly moved in the pushing process, through constant pushing, the connecting positions of the chain blocks and the pipe bundle are constantly transferred outwards till the pipe bundle completely enters the barrel, and the functions of manpower, time and cost saving are achieved.
Description
technical field [0001] The invention relates to the field of disassembly and assembly of heat exchangers, in particular to a method for installing a tube bundle of a horizontal heat exchanger. Background technique [0002] U-shaped tube heat exchanger is a kind of shell-and-tube heat exchanger, which is composed of tube plate, shell, tube bundle and other components. Under the condition of the same diameter, the U-shaped tube heat exchanger has the largest heat exchange area; it has a simple structure, compact structure, high sealing performance, convenient maintenance and cleaning, the least metal consumption and the lowest cost under high temperature and high pressure; The heater has only one tube plate, which has good thermal compensation performance and strong pressure bearing capacity, and is suitable for operation under high temperature and high pressure conditions. [0003] The maintenance process of the U-shaped tube heat exchanger will involve the disassembly and a...
