Fire pipes refer to pipe materials used for firefighting, connecting firefighting equipment and equipment, and transporting firefighting water, gas or other media. Due to special requirements, the thickness and material of fire-fighting pipes have special requirements, and red paint is sprayed to transport fire-fighting water.
Since fire protection pipelines are often in a static state, the requirements for pipelines are relatively strict. Pipelines need to be resistant to pressure, corrosion, and high temperatures. There are five main types of fire ducts:
Ductile iron water supply pipe
After adding spheroidizing agent to the cast iron of No. 18 and above, the pipe is cast by high-speed centrifugal casting using a centrifugal ductile iron machine. It is called "ductile iron pipe", referred to as ductile iron pipe or ductile iron pipe. Referred to as iron pipe and ductile iron pipe.
copper pipe
Copper tube is also called copper tube. A kind of non-ferrous metal pipe, it is a pressed and drawn seamless pipe. Copper pipe's strong, corrosion-resistant properties have made it a popular choice for modern contractors to install water, heating and cooling piping in residential and commercial buildings.
Alloy tube
Alloy pipe is a type of seamless steel pipe. Its performance is much higher than that of ordinary seamless steel pipe. Because this steel pipe contains more Cr, its high temperature resistance, low temperature resistance and corrosion resistance are better than other seamless steel pipes. pipeline. Therefore, alloy pipes are widely used in petroleum, chemical, electric power, boiler, military and other industries.
Composite pipe
Composite pipe is a pipe made of two or more materials. It is based on metal pipes and is made of polyethylene, cross-linked polyethylene and other non-metallic materials welded inside and outside. It has the advantages of metal pipes and non-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, low consumption and other advantages. They mainly include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene (PE) ) these types of water pipes.
