Weak current College】 【heating system frequently asked questions and their causes.

Heating system of the most common is corrosion, scaling, microorganism breeding three problems.

Due to poor water quality in the North, has low corrosion, and iron react to form black rust, if the system, causing the occlusive oxygen enters the system easier to form a red rust. Pipe welding residue removal of flux failed to clean and stay in the Shui system cause corrosion, most flux inside containing halogen chloride, is a strong oxidizing agent that will corrode metal copper and iron, formed in the pipeline, these spots spotted rust rusted area more easily aggravate erosion, a long time to form the heatsink, resulting in the leakage holes. Some flux contains organic acids, can promote microbial growth in the heating system. Additional heating system during the installation of metal cutting and bonding conduit bond residues, as well as a number of mineral oil, residual sand cast radiator and the system of micro-organisms can exacerbate the system as a whole or partially.

If the heating system pressure is large, warm air pressure larger places more prone to corrosion; as the water is rich in calcium and magnesium ions, causing the system to all prone to fouling. Scale of the main ingredient is calcium carbonate, heating hard water scale when the most likely to have the hottest in the system.

If a boiler heating system, the largest scale point is boiler, especially heat exchangers; if the heating system of organic nutrients, bacteria and fungi in the boiler, heat sink and very easy to grow in the pipeline, the pipeline and the heatsink on the wall and form a layer of greasy film. Bacteria and fungi can produce the heatsink to combustion of methane. These gases may be generated cold spots, radiator resulted in the radiator lower heat transfer efficiency. Who in the heat flow, these gases will result in a slight movement of the sound.

So if you want to ensure that heating of longer life, in the design of the system when system of airtight, the choice of heating when selecting heating of coating and welding techniques.
