Fire sprinkler Pipe Technical Parameters chart

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 fire sprinkler 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. 

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.

- 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 fire sprinkler pipe meets rigorous safety standards and is suitable for use in fire-fighting applications. As a result, this type of pipe is highly regulated and must be installed by a qualified professional.

- FM Approved Fire Sprinkler Pipe

FM Approved fire sprinkler system 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.

- 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 fire sprinkler pipe is made from carbon steel, which is usually coated with red or fire-resistant paint. This coating helps to protect the fire sprinkler pipe from corrosion and also makes it more visible, which is important in a fire situation. 

- 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 sprinklerpipe, 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.

The Reason Why Fire protection Pipes are in Red

Fire sprinkler pipe 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 pipe red, most manufacturers and installers use this color to help ensure that the pipes are readily visible in an emergency.
