Pipe radiator, attention manufacturers should provide the waterproof characteristics of radiator data, working pressure radiator maximum working pressure is 1.0 MPa.


Selection Points:
1) The radiator heating system shall meet the requirements of working pressure and system pressure, and shall conform to the national or industrial standards.
2) Radiators should not be used only in open heating systems and high humidity rooms (such as bathrooms and swimming pools).
3) Check the product samples identified by standard single standard heat, and the working pressure is in accordance with the requirements of use. According to the "thermal test report" and "pressure test report" issued by the national product unit test, the test results and product samples are determined for data inspection (requiring product samples to be tested, the last two test reports) year.
4) Manufacturers should provide waterproof data radiators.
5) Attention should be paid to whether the applicable conditions of the products meet the requirements of heating system and water quality. If the system can not be filled with water or water quality in the non-heating season, and the system can not meet the applicable conditions of products, it needs to use good heat treatment in anti-corrosion treatment.
6) Check the appearance of the radiator. The surface should be smooth and smooth. Interface machined surfaces should be fine and ensure verticality and smoothness.


Comparing with related products
1) The requirement of cast iron radiator for steel pipe radiator is relatively high.
2) The heating system with steel pipe radiator should adopt closed maintenance system full of water in non-heating season. At the same time, the system requires medium oxygen content (> 0.1g/m), pH value (< 20 C) = 8, and chloride ion mass (> 120 *10). The maximum working pressure of the radiator is 1.0 MPa.
3) Cast iron radiator for hot water heating system of steam heating system below 130 C or 0.2 MPa. Its product characteristics determine that its system is open, closed form and the requirements of heat medium quality system are not high.
