The wall thickness of gray cast iron radiators is thicker (left and right, while that of steel), so the gray cast iron radiators are much more resistant to oxidation, acid and alkali resistance, and galvanic corrosion resistance. Therefore its service life is also much longer. From the perspective of practical application, the gray cast iron radiator can last for more than 10 years under normal use conditions. If used and maintained well, the service life can reach many years. It can be said that the service life of the building is consistent with the technical standard of the radiator. The radiator material should comply with the provisions of B. The thickness of the water pipe is... The radiators should be tested for water vapor pressure group by group, and the pressure-bearing capacity should not be less than. The inlet and outlet water pipes of the radiator are all set under the radiator. There are no water inlet and outlet pipes on the side. The center distance between the inlet and outlet water pipes is , and the error is not greater than . The radiator is a high-quality cold-rolled low-carbon steel pipe radiator. The room is a double-lap type oval tube. The water hole diameter must reach mm. There should be no less than a uniform, dense acid-resistant, alkali-resistant, and high-temperature resistant oxygen barrier protective layer inside the radiator tube. And provide the inner cavity protective layer construction technology, practices and test reports. The threads of the radiator pipe interface should comply with the requirements of B. The threads should be intact and defect-free, and there should be protective caps on the connecting pipe threads. Each group of radiators is set to operate manually. The welding of radiators should comply with the regulations. The welds should be straight, even, neat, and beautiful, and there should be no defects such as cracks, pores, incomplete penetration, and burn-through. The spot welding spots should be even, and the distance between adjacent welding spots should not be greater than, The solder joints must not have defects such as burn-through. The heat pipe and water pipe must be welded together firmly. The outer surface of the radiator should be electrostatically sprayed after good pretreatment. The surface of the paint film should be smooth, flat, and even. There should be no bubbles, accumulation, flow, or leakage. The thickness of the primer should not be less than that of the paint film. The thickness of the paint film should not be less than that of the paint film. The adhesion should reach the level specified in B and the impact resistance of the paint film should meet the requirements in B. The material painted on the surface of the radiator should be non-toxic and odorless, and should not produce substances harmful to the human body at high temperatures, nor should it reduce its physical properties.
