Steel tube radiator
JG/T 148--2002
This standard specifies the numbers and abbreviations, requirements, test rules, markings, packaging, transportation and storage of ordinary steel radiators (hereinafter referred to as radiators). The standard is a micro-heat absorption system for high-pressure buildings with hot water as the heat medium. The water content is not high (not less than 8 × 10) and the maximum working pressure of the device is: Ma2. The following documents are used to refer to the standard. The contents of the referenced documents and their subsequent amendments or revisions are not applicable to this standard. However, the latest version of the document produced based on this standard shall apply to the latest version of the referenced document.
