The use of stray cast -iron pipes and their advantages
Numerous companies sell supplies from the best manufacturers of sewer pipes from such a material as a plain cast iron. The supplied pipes from the ardent cast iron are distinguished by unique impact resistance, excellent sound insulation and low sensitivity associated with temperature changes. The main construction objects that use cast -iron sewage systems are multi -storey buildings, laboratories, business centers, hotels, airports, office buildings, kindergartens, hospitals, as well as structures that relate to buildings with great requirements for soundproofing and insulation fire fire. Such pipes meet all modern requirements.
Cast ironic sewer pipes from Germany are used to remove effluents inside buildings during the construction of business centers, high-rise buildings and other objects that relate to structures with increased requirements for noise and fire safety. Such pipes are made by such a method as centrifugal casting de lavo. The decisive advantage of this method is that after the end of the pipe casting, the temperature is maintained at 950 ° C, while uniform and slow cooling occurs. This heat treatment leads to the formation of graphite of a sufficiently small outlet form, in this regard, there is an improvement in mechanical cast -iron properties and also a decrease in internal stresses, therefore, the limiting strength of the gap increases. In addition, a soft amount of hardness is associated with such heat treatment, which can easily process pipes.
