DN125, DN150, and DN200 galvanized steel pipes refer to galvanized steel pipes with nominal diameters of 125 mm, 150 mm, and 200 mm respectively.
The numbers DN125, DN150 and DN200 represent pipe diameters. DN refers to the nominal diameter of the pipe, which is the average of the outer diameter and the inner diameter. DN value = De-0.5 value * pipe wall thickness. De mainly refers to the outer diameter of the pipe. The outer diameter of PPR, PE pipe, and polypropylene pipe is generally marked with De, and needs to be marked in the form of outer diameter × wall thickness.
Generally speaking, DN125, DN150 and DN200 galvanized steel pipes have a wide range of applications, but you need to pay attention to their corrosion resistance when using them, and choose the appropriate pipe diameter and wall thickness as needed.
| Pipe Size | DN (mm) | Outer Diameter (mm) | Wall Thickness (mm) | Internal Diameter (mm) | Weight per Meter (kg) |
|---|---|---|---|---|---|
| DN125 | 125 | 140 | 4.5 | 131 | 16.46 |
| DN150 | 150 | 168.3 | 4.5 | 160.3 | 21.65 |
| DN200 | 200 | 219.1 | 6.0 | 207.1 | 33.40 |
Mild Steel Pipe Galvanized
DN125-DN150-DN200 galvanized steel pipe is one type of galvanized steel pipe.
Purpose. Used to transport low-pressure fluids such as water, sewage, gas, air, heating steam and other purposes. Generally Q235B straight seam welded pipe.
It has good comprehensive mechanical properties, good weldability, hot and cold processing properties and corrosion resistance, and has good low-temperature toughness. Dimensional accuracy. Relatively low, it is not prone to plate shape problems and is mainly used to control convexity.
