Fire inside and outside coated plastic steel pipe knowledge

I think we are not very familiar with the use of coated steel pipes in fire engineering, so next to give people a detailed introduction to some of the relevant knowledge in this aspect

In view of the better transmission of the coated steel pipe in the fire protection project, the operation test is carried out on time, and the scheduled task inspection is carried out, and the congestion will occur in the case of critical use

The trend of economic growth has promoted the update of new materials, and the past pipe fittings used in engineering and construction fire water supply system software are generally galvanized steel pipes.

However, in all the use of links, the electrochemical reaction appears to be more and more serious. The pipeline is used for a long time (relatively short time), and it often blocks the pipeline transport due to corrosion of the inner wall.

Fire inside and outside coated plastic steel pipe anticorrosion steps

The internal and external coated plastic steel pipe is the current lifting substitute for the steel pipe, which can be improved according to the different application conditions and uses, and the use of different coating materials effectively improves the many drawbacks of the steel pipe

For example, in some buried steel pipes, in the application period, for a long time, it is easy to rust and corrosion, and this kind of doubts can be improved in many ways, such as painting some paints, and there are special anti-corrosion paints for the doubts of corrosion of steel pipes

However, in recent years, a class of steel-plastic composite pipe has been produced, which is coated with paint inside and outside the steel pipe, so as to avoid the doubt of corrosion of the steel pipe.

The city's sewer pipes need high technical standards, the street often can see the repair of the internal and external coated steel pipe and the repair of the sewer pipe, this kind of, basically in view of the corrosion resistance of the steel pipe has not been done

After a long time of application, it is corroded, resulting in water pipe rupture, ultimately leading to the obstruction of surface water, in order to improve the improvement of many hardships, and even in view of the loss of staff economic losses, steel-plastic composite pipes can be used for municipal construction water supply and drainage, sewage pipes.

The internal and external coated plastic steel pipe is generally buried and some dark conditions, can also be heat resistant and low temperature, can be subjected to the test of temperature, in addition to the test of temperature, anti-interference can also be strong, can be used for cable protection tube, good interception effect, withstand the strength is good, the greater pressure can reach 60,000 pascals

Good flame retardant, can ensure no short circuit fire condition. During the construction period, the installation is convenient, the connection mode is diversified, and the connection mode is different according to various types.

During the construction period, according to the different uses, the connection methods are welding, grooves, flanges and wire connections, and the steel-plastic composite pipe is a high-end product of the power communication protection pipe.
