Fresh water pipework descaling
Lime or other salts are found in almost every water in their dissolved forms, in common language lime scale is responsible for hard water. Depending on the amount of lime/calcium carbonate, the dissolved carbonic acid and on the temperature of the water the minerals precipitate and start to crystallize. In other words, it deposits on surface areas. The deposits reduce heat transfer in heat exchangers and lower the efficiency of the heating installation/cooling system quite significantly. Lime scale in a hot water boiler increasing pressure losses and decreasing flow rates are other symptoms associated with the same problem.
Buildup of calcium in pipes and plumbing fittings can cause them to clog partially or completely, making them partially or totally dysfunctional. If the water has a high content of minerals in it, it will take as less as a month for the calcium deposits to build up in and around the pipes and plumbing fittings. Thus, the importance of cleaning the plumbing fittings and other pipes regularly cannot be over emphasized.
The reasons for scale to take place on the inner walls of the pipe may be attributed also to the electromagnetic forces that are being developed in between the flow of fluid and the walls of the pipes, which is a common phenomenon of any pipe material. These electromagnetic forces may be probably acting on the water flowing through the pipe, thus precipitating the salts on the pipe surface that is in contact with the flow. Such salt particles, because of their affinity, stick to the walls of the pipes and remain there. Gradually as the phenomena of deposition continues with the time of usage, the thickness of the deposit also increases. The pressure in the fluid flow and the crystalline nature of the particles (dissolved or suspended) present in the fluid are the main factors affecting the thickness of the deposit.
