I have surveyed how a hot water heating system has been plumbed. Plumbers have not been taken care of pipe corrosions. They have not washed the inside of pipes after construction since the material of pipes changed into copper pipes and engineers pointed out that solder's flux left in pipes caused corrosions. But I couldn't receive answers about cases of some accidents by corrosions in pipes because a lo pf cases have problems of claims. We can conclude that a seal up type of pipes should be used in the system they had a little possibility of matters by corrosions and all the plumbers have to do is to design and construct appropriately.Accordingly, a research group including engineers for the heating system was organized and made a guideline of techniques to design and laying pipes correctly. The point is that melting oxygen in water should be lessened. For the purpose, air has to removed completely first when water is filled in a system. secondly the water leakage has to be prevented in order not to supply melting oxygen with supplementary water for the system. IN parallel with this activities of the group, a boiler manufacture developed a efficient value for removing air in pipes and has studied whether a substance that activate plants can be used as a nature-friendly antirust.

我已经调查了热水供暖系统是如何安装的。水管工没有注意到管道腐蚀。由于管道的材料改为铜管，工程师指出管道中残留的焊料焊剂导致腐蚀，因此施工后他们没有清洗管道内部。但是我无法收到关于管道腐蚀事故案例的答复，因为很多案例都存在索赔问题。由此得出结论，在管道腐蚀问题发生的可能性很小的情况下，应采用密封式管道，管道工只需做好管道的设计和施工，为此，组织了一个由供热系统工程师组成的研究小组，制定了正确设计和铺设管道的技术指南。关键是要减少水中的氧气融化。为此，当水填充到系统中时，必须首先完全去除空气。第二，必须防止水泄漏，以便不向熔融氧供应补充水。与此同时，一家锅炉制造商开发了一种用于去除管道中空气的有效值，并研究了一种激活植物的物质是否可以用作自然友好型填料。
