light exhaust pipe radiator is strictly processed and welded with national standard seamless steel pipes. The product has a simple external structure, a large internal heat source medium storage capacity, heat dissipation, corrosion resistance, and pressure resistance. However, due to its low aesthetic appearance, it is generally suitable for large-scale applications. Large-area steam heating devices in industrial plants and workshops of industrial and mining enterprises. The heat medium can be used in high-temperature hot water, medium and low pressure steam and heat transfer oil systems. Waste heat keeps machinery and equipment from freezing. Work can open up the advantages of energy conservation and environmental protection.
Light pipe radiator technical standards: the radiator material should comply with GB13237 regulations, and the water pipe thickness is 13237.5MM. Radiators should undergo water vapor pressure tests group by group, and the pressure-bearing capacity should not be less than 1.6MP. The inlet and outlet water pipes of the radiator are all set under the radiator, and there are no water inlet and outlet pipes on the side. The center distance between the inlet and outlet water pipes is 120MM, and the error is not greater than ±5MM. The
light exhaust pipe radiator is a cold-rolled low-carbon steel pipe radiator. It is an elliptical tube double lap type indoors. The water aperture should reach 15mm; there should be no less than one layer inside the light exhaust pipe radiator, which is dense and acid-resistant and alkali-resistant. , high temperature resistance and oxygen resistance protective layer, and provide the construction technology and practice of the inner cavity protective layer. The threads of the radiator pipe interface should meet the requirements of GB/T according to the regulations of 7303. The threads should be 3-5 times intact and without defects, and there should be protective caps on the connecting pipe threads. Each group of radiators is set up with one manual running air. Radiator welding should comply with the requirements of GB/T985GJB. According to the 481 regulations, the welds should be straight, even, neat and beautiful, without defects such as cracks, pores, unwelded, burn-through and other defects; the spot welding points should be uniform, and the distance between adjacent welding points should not be greater than 40MM, the solder joints must not have defects such as burn-through. The heat dissipation pipe and the water pipe are welded firmly.
The outer surface of the glossy tube radiator is well pre-treated and adopts the electrostatic spraying process. The paint film surface is smooth, flat, and even, without bubbles, accumulation, flow, or leakage; the primer thickness is not less than 15 μm, and the paint film thickness is not less than 600 μm; The film adhesion should meet the requirements of level 1-3 specified in GB/T1720; the impact resistance of the paint film should meet the requirements of GB/T1732. The aspect ratio of the radiator should be beautiful, there should be equipotential connecting device, and equipotential connecting terminals should be set. The radiator must not have obvious deformation, scratches, collisions and burrs.
