Technical standards editor radiator material should comply with the regulations, 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 elliptical tube. The water aperture must reach mm. There should be no less than one layer of uniform, dense acid-resistant, alkali-resistant, and high-temperature resistance inside the radiator tube. Oxygen protective layer, 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/3. The threads should ensure that the 3-buckle is intact and without defects, and the connecting pipe threads should have protective caps. Each group of radiators is set to operate manually.
The welding of radiators should comply with the regulations of B/B. 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 joints should be uniform and relatively The distance between adjacent solder joints should not be greater than 1, and the solder joints should 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 pre-treatment. The paint film surface should be smooth, flat and uniform, and there should be no bubbles, accumulation, flow or leakage. The thickness of the primer should not be less than the thickness of the paint film. The adhesion of the paint film shall not be less than the level specified by B/. The impact resistance of the paint film shall meet the requirements of 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.
The diameters of the inlet and outlet pipes, vent pipes and plugs of the radiator are all. The number of brackets equipped with the radiator shall not be less than the number specified for medium type, and each bathroom radiator shall be equipped with no less than one bracket.
The bathroom radiator is an oval steel tube basket-type radiator with a towel rack. The heat dissipation of each group should not be less than the inlet and return water temperature. The center distance of the risers of bathroom radiators should be 0.2 meters, the height should be within meters, the length-to-width ratio should be beautiful, and there should be equipotential connecting devices and equipotential connecting terminals.
The radiator must not have obvious deformation, scratches, bumps or burrs.
