25mm Galvanised Pipe

Home » Galvanized Pipe » 25mm Galvanised Pipe

Introduction

25mm represents the “nominal diameter” of the galvanized pipe. A layer of anti-corrosion zinc is applied to the surface by hot-dip galvanizing or electro-galvanizing. It has the characteristics of strong corrosion resistance, high strength and high cost performance.

We have galvanized pipes of various sizes, including galvanized round pipes, square pipes and rectangular pipes. The products are of high quality. If you have any questions, please contact us.

25mm galvanized pipe weight of different wall thickness

Calculation formula for the theoretical weight of galvanized steel pipe (kg/m) = (outer diameter − wall thickness) × wall thickness × 0.02466

Wall thickness (mm)outer diameter (mm)Weight (kg/m)
1.530.71.25 – 1.28
1.630.51.30 – 1.35
229.71.62 – 1.68
2.528.72.00 – 2.08
2.828.12.23 – 2.32
3.227.32.52 – 2.62
3.626.52.82 – 2.93

Note:

  • The weight of the galvanized pipe in the table includes the weight of the zinc layer, and the weight of different zinc layers is different.
  • 25mm refers to the “nominal diameter” (DN25), which is a standardized code used to indicate the diameter capacity of the pipe, not the actual inner or outer diameter.
