The anticorrosive heat preservation pipe has good corrosion resistance and heat preservation performance, and has been widely used and promoted in construction, and constantly improved and promoted. Corroded pipeline insulation has different processing types and methods, different processing methods determine that pipelines have different properties and functions, and the scope of use has changed. As the name implies, it is to increase the number of external spiral steel pipe corrosion insulation grade protection, in order to achieve low temperature use. Generally speaking, the inorganic zinc-rich coating used for second-degree pipeline insulation, whose temperature is more than 400 C, belongs to corrosion coating. The pipe orifice uses polyethylene film called 3-layer PE or cold-sealed tape to achieve pre-installation to prevent moisture from entering water or construction.


Helical steel pipe insulation is suitable for high temperature, water pump and fuel pump, chemical pump corrosion. Insulated pipeline centrifugal pump series products have the characteristics of low noise, good performance, energy saving and reliability. The insulation material used is multi-layer wrapping wrong joint, so it can effectively reduce heat loss, and can control the measures of jacket surface to prevent the cold bridge from occurring, so as to ensure the temperature control of the shell. The spiral steel pipe is coated with insulating multi-layer aluminium foil reflecting layer, which can effectively reduce heat loss and make the steam pipe more economical and reasonable. The insulating layer of anticorrosive steel pipe has good corrosion resistance and thermal insulation performance. It has been widely used and promoted in design and construction. At present, it has been continuously improved and promoted. Spiral steel also has different processing types and methods, and different processing methods determine that pipe has different properties and functions, and the scope will change!
