Ductile water supply cast iron pipe
Pipes made of cast iron with a size of 18 or more, added with nodulizer, and centrifugally cast by a centrifugal ductile iron machine are called "ductile cast iron pipes" (Ductile Cast Iron Pipes)
One kind of non-ferrous metal pipes are pressed and drawn seamless pipes. Copper pipes have the characteristics of sturdiness and corrosion resistance, and are widely used in running water pipes, heating and cooling pipes of all commercial houses.
Alloy pipe is a kind of seamless steel pipe, its performance is much higher than the general seamless steel pipe, because this kind of steel pipe contains more Cr, its high temperature resistance, low temperature resistance and corrosion resistance are inferior to other seamless steel pipes, so alloy pipes are widely used in petroleum, aerospace, chemical, power, boiler, military and other industries.
Composite pipe is a pipe composed of two or more materials. It is based on metal pipes, and is welded with non-metallic materials such as polyethylene and cross-linked polyethylene. It has the advantages of metal pipes and non-metal pipes.
As an important part of chemical building materials, plastic pipes are widely accepted by users due to their superior performance, hygiene, environmental protection, and low consumption. They mainly include UPVC drain pipes, UPVC water supply pipes, aluminum-plastic composite pipes, and polyethylene water supply pipes.
