With the continuous development of electric heating cable technology, more and more pipeline antifreeze heat preservation began to use electric heating cable system, it accompanied by high efficiency, energy saving and environmental protection, operation is also relatively economic. So is not in different material pipeline using electric accompanied by heat system can play the role of heat preservation and antifreeze, for example, like ductile iron pipeline and valve parts on the use of electric accompanied by heat is not also can have other pipeline on the use of the same effect? In fact, it is the same, as long as in doing the electric accompanies heat insulation design, seriously consider the special characteristics of ductile cast iron can be.

                      Here to give you a brief introduction to the characteristics of ductile iron, it is a kind of cast iron containing spherical graphite, microelements and rare earth elements, the use of performance close to steel. General cast iron graphite presents flake, and contains rare earth elements so that the graphite presents a spherical, so it is called "ductile iron". Its mechanical properties of the strength is particularly high, frost resistance, heat resistance is also relatively high, so it will often be used instead of steel casting process.

                  Because of its corrosion resistance is relatively strong, so often used in the environment is more complex buried pipeline, for the buried cast iron pipeline need to use the electric heating cable system to prevent cold thawing it, this needs to be based on the local temperature environment and buried soil cover structure and depth. Previously we introduced the ductile iron pipe has a very good frost resistance, but, in many cases used in the exposed environment of the pipeline or valve parts, in the encounter of the colder climate environment, there will be freeze blocking or freeze cracking, so, still need to use the electric heat tracing cable system for its anti-freezing and heat preservation.

                      Electricity accompanies heat system is widely used in pipeline antifreeze, instrument antifreeze, process maintenance temperature, process accompanied by heat, tank accompanied by heat and heating and other applications, for all walks of life customers to solve all kinds of pipeline antifreeze and process maintenance temperature of the many difficult problems, by the industry customers consistent high praise.
