Fire-fighting equipment, such as the water supply lines for fire sprinklers and hydrants, must be constructed of high-quality steel to ensure their long-term effectiveness. Water, gas and other fire-fighting substances require pipes of the appropriate volume and strength to withstand corrosion as well as high temperatures and pressures. BAOLAI can give you better guidance in this regard.
The characteristics of the steel make it an excellent material for fire extinguishing systems. Below we discuss the standards for managing fire pipes and the various uses of these pipes. When you use the correct steel pipe in a fire alarm system, you do not need to worry that it will not work properly when needed.
Safety requirements for piping works
ASTM International is a standards organization that publishes specifications for various services and materials and oversees fire protection piping standards. The American Society for testing and materials, as it was previously known, develops and publishes widely accepted and widely used standards.
There are three types of fire pipes:
1. ANSI/ASTM Standard A53 The ASTM A53 Fire Piping Standard covers the widest range of fire piping thicknesses. Normal (Schedule 40) very strong (schedule 80) extra strong twice normal (schedule 160) lower schedule numbers mean thinner pipes when it comes to wall thickness. ASTM A53 states that sprinkler systems must use at least schedule 40 piping, but heavier piping may be used if necessary.
2. ANSI/ASTM standard A135 electric resistance welded pipe is covered by this standard. This fabrication method allows thinner wire walls while also reducing corrosion. These pipes must comply with at least schedule 10 in order to be used.
3. ANSI/ASTM standard A795
ASTM A795 is the specification for sprinkler pipes. Wall thicknesses for these pipes range from Schedule 10 to schedule 40.
For all three, red paint or polymer epoxy coating is required. Black steel or hot dip galvanized versions are also available, which help reduce corrosion.
For fire extinguishing pipes with rated values
Fire suppression systems can use all three types of rated piping, including:
Riser pipes for firefighting
Fire sprinkler hoses
There are multiple ways to connect pipes together.
All types of pipes can be welded together as long as the work is done by a certified welder. A third option is to thread the pipe, but this is usually limited to schedule 40 pipes unless it has been specifically reviewed and approved by some other standards body such as NFPA 13.
Roll grooves and cut grooves are two other options for joining. Roll grooves can be applied to any pipe, while cut grooves can only be applied to schedule 40 or thicker pipe. These connections allow the use of elastomeric gaskets to seal the lines.
Regardless of the application, it is critical to choose the proper treatment to avoid damage to your fire suppression efforts from corrosion and other elements. If you follow these guidelines, you will be in great shape.
