Fire Sprinkler Pipe
Fire Sprinkler Pipe
Fire sprinkler pipe is a type of pipe used in fire fighting. It is usually red in color and has fittings and connections that allow it to be connected to a water source, such as a roof tank or city water supply. The pipe is pressurized and delivers water to sprinklers that are triggered by heat from a fire. Fire sprinkler pipe is an important part of any fire safety system and can be the difference between a small fire and a major disaster.Â
Fire sprinkler pipe must be able to withstand high temperatures and pressures, as well as the weight of the water it carries. Fire sprinkler pipe is typically made from steel, and it is typically installed in the ceiling of a building. Fire sprinkler pipe is fitted with various types of fittings in order to make connection to the main, branches and water sprinklers.

Fire Sprinkler 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.
Different Connection Types of Fire Sprinkler Pipes
There are four major types of connections used in fire piping systems: welding joint, threaded, grooved, and flanged. A welding joint is the most common type of connection and is used when welding two pieces of metal together. Threaded connections are used when screwing two pieces of metal together. Grooved connections are used when two pieces of metal need to be joined together but cannot be welded or screwed. Flanged connections are used when two pieces of metal need to be joined together but there is a gap between them. Each type of connection has its advantages and disadvantages. The welding joint is the strongest type of connection, but it is also the most expensive. Threaded connections are less strong than welding joints, but they are less expensive and easier to install. Grooved connections are less strong than welding joints and threaded connections, but they are easier to install. Flanged connections are the weakest type of connection, but they are the cheapest to install.
production standard of Fire Sprinkler Pipe
- UL Listed Fire Sprinkler Pipe
UL listed fire sprinkler pipe is a fire fighting sprinkler piping system that has been tested and approved by Underwriters Laboratories. This type of pipe is typically used in commercial and industrial buildings where fire safety is a high priority. The UL listing ensures that the pipe meets rigorous safety standards and is suitable for use in fire-fighting applications. In addition to being UL listed, fire sprinkler pipes must also meet local building code requirements. As a result, this type of pipe is highly regulated and must be installed by a qualified professional. While UL-listed fire sprinkler pipe is more expensive than other types of piping, it provides peace of mind knowing that your property is protected in the event of a fire.
- FM Approved Fire Sprinkler Pipe
FM Approved fire sprinkler pipe is specifically designed and tested for use with fire sprinkler systems. It is made from high-quality materials that can withstand high temperatures and pressures, ensuring that the system will work properly in the event of a fire. FM Approved pipe is an essential part of any fire sprinkler system, and it is important to choose a reputable supplier that can provide high-quality pipe that meets your specific needs.
- ASTM A795 Fire Sprinkler Pipe
ASTM A795 fire sprinkler pipe is one of the most commonly used fires fighting products in the United States and other countries. It is widely available and relatively affordable, making it a popular choice for both commercial and residential applications. The pipe is made from carbon steel, which is usually coated with red or fire-resistant paint. This coating helps to protect the pipe from corrosion and also makes it more visible, which is important in a fire situation.Â
- ASTM A53 Fire Sprinkler Pipe
Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded, and Seamless. ASTM A53 is designed for mechanical and pressure applications, but it is also suitable for everyday use in steam, water, gas, fire sprinkler, and airlines. Subject to particular conditions, it is appropriate for welding and forming operations such as coiling, bending, and flanging.
- ASTM A135 Fire Sprinkler Pipe
ASTM A135 fire sprinkler pipe is a type of steel pipe that is commonly used in fire fighting applications. The American Society for Testing and Materials (ASTM) designates this type of pipe as A135. fire sprinkler pipe is required to be coated with a red coating in order to be visible, and it is also required to have a thicker wall than standard steel pipe. This type of pipe is most often used in commercial and industrial buildings, as well as in some residential applications. ASTM A135 fire sprinkler pipe is an important part of any fire safety system, and it should be installed by a qualified professional.

The Reason Why Fire Sprinkler Pipes are in Red
Fire sprinkler pipes are usually painted red so that they are easily visible in the event of a fire. The roof is one of the most common places for a fire to start, and the bright color of the sprinkler pipes helps firefighters quickly locate them and start fighting the blaze. In addition, the red color helps to differentiate the pipes from other types of piping, such as those used for plumbing or gas lines. While there is no legal requirement to paint fire sprinkler pipes red, most manufacturers and installers use this color to help ensure that the pipes are readily visible in an emergency.
