Composite heating radiator

1 Scope

China's national standard for composite heating radiators - those made from two or more different materials. It specifies the terms and definitions, the classification and marking, the materials, the requirements, the test methods, the inspection rules, the records, instructions and certificates, and the packaging, transport and storage, and it applies to radiators used in industrial and civil building heating systems. The composite radiator exists because the two things a radiator must do are best done by different metals. Steel is cheap and strong and takes pressure well, but it corrodes in the water of an open heating system. Aluminium radiates heat far better for its weight and cost, but it is attacked by the alkaline water that protects steel, and it cannot be used with copper. So the common construction is a steel or copper waterway inside an aluminium fin block: the water touches only the corrosion-resistant metal, and the heat is given off by the metal that gives it off best. What that arrangement needs is a specification for the joint between them.

This standard specifies the terms and definitions of the composite heating radiator, classification and marking, material, requirements, test methods, inspection rules, Records, instructions and certificates, packaging, transportation and storage. This standard applies to industrial and civil construction heating system in two or more than two kinds of materials from the heating radiator (hereinafter referred to as Radiator), including the water temperature is not higher than 95 °C, water quality in line with GB/T 29044-2012

4.5 provisions of the metal flow radiator to And the water supply temperature is not higher than 80 °C plastic flow radiator.
