Summary
This standard specifies spiral plate heat exchanger (hereinafter referred to as " heat ") the design, manufacture, inspection and acceptance requirements. This standard applies to removable, non- removable heat. This standard applies to nominal diameter, nominal pressure ranges: a) nominal diameter DN �� 2200mm, b) Nominal pressure PN �� 2. 5MPa, c) nominal diameter (mm), nominal pressure (MPa) the product is not greater than 3000. Note: The above parameters beyond the range the heat exchanger may also refer to the standards for the design and manufacture, But PN> 4. 0MPa time, subject to the National Standardization Technical Committee approved boiler and pressure vessel assessment. This standard applies the design temperature range
