JIS G3452 is a Japanese industrial standard that specifies the requirements for carbon steel pipes used for ordinary piping. These pipes are commonly utilized in various applications, including plumbing, gas piping, and other industrial uses where moderate pressure and temperature conditions are present. Here is a detailed overview of JIS G3452 carbon steel pipes.
Manufacturing Process
Hot Rolling and Cold Drawing: Pipes are typically manufactured through a hot rolling process, followed by cold drawing to achieve the desired dimensions and surface finish.
Welding: The pipes can be seamless or welded, with welded pipes being more common for standard applications.
Surface Treatment: Pipes may undergo surface treatment such as galvanizing (zinc coating) to enhance corrosion resistance.
Benefits of JIS G3452 Carbon Steel Pipes
Durability: Carbon steel pipes offer good strength and durability, making them suitable for various applications.
Cost-Effective: Generally more affordable compared to other types of steel pipes like stainless steel.
Versatility: Can be used in a wide range of applications, including water supply, gas piping, and industrial uses.

main features and applications
|
|
1) used for the transportation of water (not water supplies), air, steam, oil, gas, and other fluids at relatively low pressures.
2) two different kinds: black pipe and white pipe. operating temperature range: -15 to 350°c.
3) mzn grade groove corrosion-resistant erw steel pipe is also sold, for protection against the groove corrosion that may occur along the welds of erw steel pipe.
