There are 12 standard radiators in China, namely 1 national standard, 10 construction industry standards and 1 temporary technical condition. One national standard is: GB/T13754-1992 method for measuring the heat dissipation of heating radiators. High-power heat pipe radiator
10 industry standards are: steel closed string, finned tube convector, column type, plate type, steel tube radiator, high power radiator; gray cast iron column airfoil, column type, airfoil radiator; aluminum Column wing radiator; series parameters, threads and accessories. One temporary technical condition is a steel flat tube radiator.
The earliest one was released in 1986 and has not been revised in the past 20 years. The steel string has been listed as a restricted product by the Ministry of Construction No. 218. Nowadays, China's radiators have developed greatly, and many new products have been widely used and used, such as copper-aluminum composite radiators, decorative radiators, copper-tube aluminum-wings (strings, windings) convectors, steel-aluminum composite radiators, and so on. These widely used products do not yet have industry standards, which brings great difficulties for supervision and inspection, market management, design selection, construction and acceptance. Some standards have not adapted to the needs of the new development of the times, such as cast iron radiators, reform of the heating system, household metering, heat charges, and room temperature control, it is not possible to use internal cavity cleaning. The net cast iron radiator, because it will affect the failure and damage of the heat meter and the temperature control valve, but the new standard has not been introduced. The standard of the radiator is seriously lagging behind, which brings some confusion to the market, which makes the production enterprises and consumers have no choice but to affect the healthy development of the radiator.
The relevant departments concerned can pay attention to this issue, formulate and revise the radiator standards as soon as possible, improve the industry level, and promote the development of the industry.
