Introduction
GB/T 28712 "Heat exchanger types and basic parameters" aims to standardize the typical structural types of heat exchangers used in the energy industry, fully considering the installation
In line with the development trend of large-scale installations, taking into account the product standards and construction level of my country's heat exchangers, the applicable range of parameters and their supporting dimensions are clarified. consider
The functions, structures, and parameters of different heat exchangers are obviously different, and they are composed of six parts.
---Part 1.Floating head heat exchanger.
---Part 2.Fixed tube plate heat exchanger.
---Part 3.U-shaped tube heat exchanger.
---Part 4.Thermosiphon reboiler.
---Part 5.Spiral plate heat exchanger.
---Part 6.Air-cooled heat exchanger.
Heat exchanger type and basic parameter standards are of great significance to the realization of standardization, serialization, generalization and scale of heat exchangers in my country.
righteous. For large-volume and wide-ranging heat exchanger products, the standardization of their structures and parameters can first promote the standardization of product construction, improve design quality,
efficiency; secondly, it can save tools, tooling, material consumption and backlog in manufacturing and use; finally, it can facilitate users to select and use products.
Replacement, repair and interchange. In recent years, the construction of large-scale refining and chemical integration projects in our country has entered a period of rapid development. As a typical energy-consuming equipment
The usage of heat exchangers has increased significantly; the large-scale installation has pushed the structural size of heat exchangers to new heights, and the demand for large-scale single equipment is increasing.
Outstanding; the construction and implementation of a large number of engineering projects has accumulated rich experience in design, manufacturing and engineering application for the construction of heat exchangers. at the same time,
GB/T 151 "Heat Exchanger" has also been revised accordingly, forming for the first time a comprehensive product standard that comprehensively covers the typical structure of heat exchangers, and
Applicable parameters have been significantly adjusted. To this end, it is necessary to revise the heat exchanger type and basic parameter standards to adapt to industry and standard development.
exhibition needs.
This document focuses on the large-scale development needs of U-shaped tube heat exchangers. Through the environmental protection of product design, production, use and standardization,
The research and analysis of this section has greatly expanded the types and basic parameters of U-shaped tube heat exchangers, and promoted the efficient selection and construction of this type of products.
Manufacturing, maintenance and exchange are of positive significance to the implementation of my country's "energy saving and emission reduction" strategy and the promotion of "green design".
