Classification of fire steel pipes

There are six selected materials for fire protection pipes: ductile iron pipes, copper pipes, stainless steel pipes, alloy pipes, composite pipes, and plastic pipes.

Ductile water supply cast iron pipe

Pipes made of molten iron above No. 18, added with a nodularizer, and centrifugally cast at high speed by a centrifugal ductile iron machine are called "Ductile Cast Iron Pipes", referred to as ductile iron pipes, ductile iron pipes, and ductile iron pipes. Ductile cast pipes, etc.

copper pipe

A copper tube is also called a purple copper tube. A type of non-ferrous metal pipe, it is a pressed and drawn seamless pipe. Copper pipes are strong and corrosion-resistant, and have become the preferred choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial buildings.

Alloy tube

Alloy steel pipe is a type of seamless steel pipe. Its performance is much higher than that of ordinary seamless steel pipes because this steel pipe contains more Cr, and its high-temperature resistance, low-temperature resistance, and corrosion resistance are better than others. Seamless steel pipes cannot compare, so alloy pipes are widely used in petroleum, chemical, electric power, boiler, military, and other industries.

Composite pipe

Composite pipe is a pipe composed of two or more materials. It is based on metal pipes and is welded with polyethylene, cross-linked polyethylene, and other non-metallic materials inside and outside. It has the characteristics of metal pipes and non-metallic pipes. Advantages of metal pipes.

plastic pipe

As an important part of chemical building materials, plastic pipes are widely accepted by users for their superior performance, hygiene, environmental protection, and low consumption. They mainly include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, and polyethylene (PE) These types of water supply pipes.
