Product Introduction
1 shell 2 tube pass heat exchanger
The development of tube and shell heat exchanger was generally support type of development, from the bow baffle plate support, to baffle rod support is the last to self supporting tube, with the change of the shell side support structure, shell side film heat transfer coefficient of tube and shell heat exchanger performance to increase continuously, the development trend of the pressure drop performance for lowering development trend, to improve the comprehensive heat transfer performance of the heat exchanger obviously.
Material Selection
Heat exchanger with materials, steel products (steel plates, steel pipes, profiles, forgings) should comply with the following quality and specifications of the existing national standards, industry standards or relevant technical conditions, steel shall comply with the requirements of GB GB713-2008, the selection of steel should accept the state bureau of quality and technical supervision issued "pressure vessel safety technology and supervision code".
Among them, the steel used for compression elements and non-compression elements welded directly to the compression elements must be accompanied by the steel quality certificate of the steel mill (or copy, copy shall be stamped with the seal of the supply department).
