GB/T 28712.1-2023 Types and basic parameters of heat exchangers—Part 1:Floating heat exchangers
Abstract
This document specifies the types and basic parameters of floating head internal flow and external flow heat exchangers (hereinafter referred to as "heat exchangers") and floating head condensers (hereinafter referred to as "condensers").
This document is applicable to the following heat exchangers and condensers:
a) Internal flow heat exchangers with a nominal diameter not exceeding 2,600 mm and a nominal pressure not exceeding 6.4 MPa;
b) External flow heat exchangers with a nominal diameter not exceeding 1,000 mm and a nominal pressure not exceeding 4.0 MPa;
c) Floating head condensers with a nominal diameter not exceeding 2,200 mm and a nominal pressure not exceeding 4.0 MPa.
Note: The data in this document are based on hook-and-loop floating heads (type S), and do not involve retractable floating heads (type T).
