In recent years, polyethylene (PE) pipes have been widely used in municipal water supply, agricultural and forestry irrigation, sewage, and fire pipeline engineering due to their superior performance characteristics.

Everyone knows that currently, most of the outdoor buried fire pipes in our country use galvanized steel pipes. However, with the widespread use of PE pipes, they are gradually recognized and more widely used in the fire pipeline industry. When the working pressure of the fire water supply system is not greater than 1.2MPa, the buried pipeline part needs to use PE water supply pipes with a nominal pressure of 1.25MPa or above.

So can PE pipes be used for outdoor fire pipes? Let's learn about PE pipes together:

Firstly, the selection of fire pipe materials:

The selection of outdoor fire water transmission and distribution pipeline materials shall be based on the pipe diameter, internal pressure, external load and the terrain, geology and pipe supply of the pipeline laying area, and the principle of safe operation, durability, leakage reduction, convenient construction and maintenance, and economic rationality.

Fire protection pipes are mainly divided into indoor and outdoor types

Because steel pipes are easily corroded underground and inconvenient to operate, we urgently need a new type of pipeline that is corrosion resistant, anti-aging and can meet the requirements of fire protection pipeline.

The main material of PE pipes is high-density polyethylene, which has good creep resistance, corrosion resistance, convenient installation and construction, flexibility, and can reach the pressure of kilograms required for fire water supply.

So PE pipes can be used for fire protection.

At present, PE pipes for firefighting are mainly used in outdoor firefighting pipelines. In engineering design, the selection of pipes is determined based on the length and pressure of the pipeline. Generally, PE pipes for firefighting do not pay much attention to hygiene indicators, mainly in terms of pressure. The acceptance standard is generally 1.5 times the pressure level of the pipe itself. The PE fire pipe fittings are also very complete and can fully meet the construction requirements, so it needs to be vigorously promoted.
