What type of piping is used for fire protection?

Table of Contents

Fire-fighting pipes refer to pipe materials used for fire-fighting, connecting fire-fighting equipment, and transporting fire-fighting water, gas or other media. Due to special requirements, the thickness and material of fire-fighting pipes have special requirements, and they are sprayed with red paint to transport fire-fighting water.

Fire Hose

Since fire-fighting pipelines are often in a static state, the requirements for pipelines are relatively strict. Pipelines need to be resistant to pressure, corrosion and high temperature. There are five main types of fire pipes:

  1. Ductile iron water supply pipe

After adding No. 18 and above cast iron into nodularizing agent, it is cast by centrifugal ductile iron machine at high speed. It is called “ductile iron pipe”, referred to as ball pipe, ductile iron pipe and ductile iron pipe.

  1. Copper pipe

Copper tubes are also called red copper tubes. A non-ferrous metal pipe is a pressed and drawn seamless pipe. The strong, corrosion-resistant properties of copper tubing have made it a popular choice for modern contractors installing plumbing, heating, and cooling piping in residential and commercial buildings.

  1. Alloy tube

Alloy pipe is a kind of seamless steel pipe, its performance is much higher than that of ordinary seamless steel pipe, because this kind of steel pipe contains more Cr, its high temperature resistance, low temperature resistance and corrosion resistance are better than other seamless steel pipes. Therefore, alloy pipes are widely used in petroleum, chemical, electric power, boiler, military and other industries.

  1. Composite pipe

Composite pipes are pipes composed of two or more materials. It is based on metal pipes, and the inside and outside are welded by non-metallic materials such as polyethylene and cross-linked polyethylene. It has the advantages of metal pipes and non-metal pipes.

  1. Plastic pipes

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

Fire pipe installation process:

Installation preparation → installation of main pipeline → installation of alarm valve → installation of riser → installation of sprinkler layered main pipeline, fire hydrant and branch pipe → installation of water flow indicator, fire pump, high water tank, water pump combination → pipeline pressure test → pipeline flushing → Sprinkler branch pipe installation (system comprehensive pressure test and flushing) → Throttling device installation → Alarm valve accessories, fire hydrant accessories, nozzle installation → System water test
