Exhaust valve: When the radiator part is not hot, an exhaust valve is required. Open the gas release valve to release the gas until the gas is exhausted. When water overflows, close the bleed valve.

​If the entire set of radiators is not hot or hot, it may be that the lock valve at the inlet of the radiator, the temperature control valve and the return valve at the outlet are closed, making the h

​At present, the best material radiator on the market is copper-aluminum composite radiator, but for home users, aluminum radiator is more cost-effective.

The heating system using steel pipe radiators should be a closed, non-heating season full water maintenance system.

The radiator should meet the working pressure and system pressure requirements of the heating system, and should comply with national or industry standards.

Through the maintenance of the finned tube, the service life of the finned tube will be greatly increased. The long-term use of any item is inseparable from care and maintenance, and the finned tube i

​In a heat exchanger composed of ordinary steel pipes (smooth tubes), in many cases, the heat transfer coefficient of the fluid outside the tube and the fluid inside the tube to the tube wall is diffe

Before installation, we must carry out on-site measurement to determine the model, number of finned tube radiators and the specific installation location.

When the air supply outlet temperature of the finned tube is higher or lower than the standard value, you should check and find out whether the following conditions have occurred.

​In the progressive die, the outer shape of the punched part is formed by punching the leftover material around the punching part.

Sheet materials, molds and equipment are the three elements of stamping processing. Stamping is a method of metal cold deformation processing.

Adhesion, scratches: defects on the surface of the part or mold due to the friction between the material and the convex mold or the concave mold.
