It is well known that fire pipe has high requirements, for example, each pipe needs to be hydro-tested and the manufacturer needs to have ul listed and fm approved certification. This article will cover the range of standards, certifications, testing and more for fire protection pipe.

Fire Pipe Technical Parameters

Fire Sprinkler Pipe is a type of pipe that is commonly used in fire sprinkler systems. It is usually made of steel or iron, and it is typically red or orange. The pipe is coated with a substance that helps to prevent corrosion, and it has a working temperature of -30℃ to 80℃ (-22℉ to 176℉). 

The working pressure of the pipe is 0.1 ~ 0.25 Mpa, and it can be connected using various methods, such as welding, threading, grooving, and flanging. The thickness of the coating on the pipe ranges from 250μm to550 μm.

What are the production standards

In TUSPIPE manufacturer, we can produce fire protection pipes with the following standards: ul certification, fm certification, astm a795 standard, astm a53 standard, astma135 standard fire protection pipes.

 

Hydro-Tested

What is Hydro-Tested

Hydrotesting is a method of testing the sealing performance and strength of fire resistant pipework. By injecting water at a certain pressure into the pipework system and observing whether there is any leakage or deformation of the pipework, the fire resistance of the pipework can be assessed. This testing method can effectively detect potential hazards that may occur in pipelines during a fire so that timely repairs and replacements can be carried out.

Methods of Hydro-Tested

Pre-test preparation

The following preparations need to be made prior to performing a hydrotest:

Check that the pipework is installed to ensure its integrity.
Prepare the water pressure test instruments, such as pressure gauges, water pipes and seals.
Clean up any residue in the pipework to ensure that the inside of the pipework is clean and tidy.
Select test instruments
According to the design pressure and specifications of the fire protection pipework, choose the appropriate test instrument. Generally speaking, the pressure range of the testing instrument should be higher than the design pressure of the pipeline to ensure the accuracy of the test.

Matters to be noted during testing

The following points need to be noted when carrying out the water pressure test:

When injecting water into the piping system, the pressure should be increased slowly to avoid damage to the piping caused by over-pressurisation.
Changes in the pressure gauge should be closely monitored during the test, as well as whether there is any leakage or deformation of the pipeline.
The test pressure should be gradually increased until it reaches the design pressure and kept for a period of time to fully check the performance of the pipeline.
During the testing process, safety precautions should be taken to avoid accidents.

Based on the results of the hydraulic pressure test, the performance of the fire protection pipework can be assessed. Generally speaking, if the pipe shows no leakage or deformation during the test and is able to withstand the design pressure, the pipe is considered to meet the requirements. If the pipe shows leakage or deformation, or is unable to withstand the design pressure, it indicates that there are safety hazards and the pipe needs to be repaired or replaced.

TUSPIPE FM Approved & UL Listed

Why these certifications are needed

UL listed fire pipes undergo a series of comprehensive tests to ensure they can withstand extreme temperatures and maintain their structural integrity during a fire. This certification provides reassurance that the pipe will effectively contain and control the spread of flames, giving valuable time for evacuation and minimizing property damage.

Similarly, FM approved fire pipes have undergone rigorous testing by Factory Mutual Global, a leading authority in industrial and commercial property insurance. This approval signifies that the pipe has met strict criteria for performance, durability, and resistance to fire hazards.
