Understanding The Weight Chart Of 25mm Gi Pipe Sizes In Mm And Inches

Introduction

Galvanized steel pipe is a type of steel pipe with a zinc coating on the surface. This type of steel pipe is mostly used in pipelines, fences and some structural applications. This article mainly introduces the size, weight and some general data of 25mm galvanized pipe.

There are different ways to express the size: the difference between metric and imperial units, that is, millimeters and inches. This article will also introduce these two ways of expression and how to convert them to each other.

In 25mm galvanized pipe, 25mm usually refers to the nominal inner diameter. What is its corresponding weight? Its weight is mainly related to the wall thickness, and the wall thickness is generally divided into Class A, Class B, and Class C.

What Does “25mm GI Pipe” Mean?

In the conventional marking of pipes, 25mm usually refers to the nominal inner diameter or inner diameter. If converted to inches, it is about 1 inch. Usually, this mark also corresponds to the corresponding outer diameter, wall thickness and pressure level.

Pipe Class Nominal Bore Outer Diameter Wall Thickness
A (Light) 25mm (1″) ~33.4 mm ~2.0 mm
B (Medium) 25mm (1″) ~33.4 mm ~2.6 mm
C (Heavy) 25mm (1″) ~33.4 mm ~3.2 mm

The above size specifications are based on the IS1239 standard and similar GI specifications internationally.

Weight Chart for 25mm GI Pipe (Approximate Values)

Pipe Class Length (meters) Weight per meter (kg/m) Total Weight (kg)
A Class 6 2.39 14.34
B Class 6 3.27 19.62
C Class 6 4.00 24.00

For example: Order 10 6-meter 25mm GI pipes (B-grade), the total weight is about 196.2 kg.

Why Pipe Weight Matters

1. Cost Calculation

GI pipes are usually priced per kg or per inch. Then knowing the corresponding weight can better calculate the price.

2. Structural Design

In the pipeline system, pressure bearing is also an important condition. The load bearing mainly depends on the wall thickness and weight of the pipe. Generally, C-grade standard pipes can be used more for high-pressure or outdoor pipeline systems.

3. Logistics and Handling

Correctly calculating the weight can make installation and transportation safer.

How to Convert Between mm and Inches

Metric (mm) Imperial (inch)
15 mm 1/2 inch
20 mm 3/4 inch
25 mm 1 inch
32 mm 1 1/4 inch
40 mm 1 1/2 inch
50 mm 2 inch

25 mm is widely considered to be equivalent to 1 inch, so it can be converted in this way in pipeline systems around the world.

Where Is 25mm GI Pipe Commonly Used?

Household water supply system

Garden and greenhouse irrigation system

Structural frame

Fence

Air compressor pipeline

Among the pipe specifications, Class B is the most widely used.

Summary

The above mainly introduces the weight and size specifications of 25mm galvanized farmers and herdsmen. After understanding these contents, you can:

Choose a more suitable grade (A, B, C) according to your needs

Better calculation of steel pipes

Can convert between millimeters and inches

Ensure compatibility in the pipeline system

Therefore, when you make a specific choice, you can mainly refer to the above items to choose the right galvanized pipe. But when purchasing, you should also communicate with the supplier in time about the size specification table.
