Production Description:
The GZ5-25 series steel radiators are made of high-quality material.Low-carbon steel, Manufactured from 4 round tubes of 25mm diameter and 2 end caps, fully automatic welded. After welding assembly, the internal cavity is treated with degreasing, rust removal, phosphatizing, coated with organic anti-corrosion materials, and dried. The outer surface is cleaned, shot-blasted, and then subjected to two layers of electrostatic spray paint baking. The internal anti-corrosion material is organic material Kynar 2398, which has strong acid and alkali resistance. The use of integral end caps ensures smooth water flow, overcoming the drawback of small through-holes in lap-welded radiators. The product is tested twice at 1.6Mpa pressure before leaving the factory to ensure quality.
The steel series radiators maintain the German style in appearance, exuding stability, beauty, and elegance.
Product Specifications:
• End Cap: Commonly known as the "head" section, it is made by stamping SPCC cold-rolled steel plate, with a thickness ranging from 1.8mm to 2.5mm.
• The overall end piece ensures smooth water flow and high volume, overcoming the缺点 of the small through holes in the butt-welded radiator.
• Pipe: Bending and welded from Q195 low-carbon steel, thickness of 1.3mm-2.5mm, cut to length based on the radiator's height.
• German mature automatic welding technology between the header and the upright pipe, with circular automatic welding assembly between columns based on length.
• The interior cavity is lined with a 2-layer organic anti-corrosion coating, specifically designed for the AT2398 gold fluorine heat sink, and is vacuum pressure-filled for anti-corrosion purposes.
The outer surface is coated with two layers of electrostatic powder using international standard spray technology, cured at a high temperature of 290°C.
