ERW Pipes

ERW Pipes


ERW (Electric Resistance Welded) pipes are widely used in various industrial sectors for their uniform wall thickness, smooth surface finish, and high strength. Whether for water transportation, structural applications, or oil and gas pipelines, ERW pipes are a go-to solution in modern engineering. One critical aspect in their application is understanding the ERW pipe weight chart, which plays a key role in logistics planning, structural design, and procurement.

pipex.ai stands out in the competitive India B2B marketplace by explaining what the ERW pipe weight chart entails, how weights are calculated, and why it’s especially relevant for the growing B2B market in India. We'll also look at how India's B2B market platforms and B2B sites in India support the buying and selling of ERW pipes with reliable weight data.


What Are ERW Pipes?

ERW pipes are made by rolling metal and welding it longitudinally across its length using electric resistance. The process ensures consistent quality and dimensional accuracy, making these pipes suitable for a wide range of applications, from infrastructure projects to mechanical structures.

Compared to seamless pipes, ERW pipes are more cost-effective and come in standard sizes that suit most engineering requirements. Their popularity has surged in the India B2B market, where cost, strength, and reliability are essential factors.


Importance of ERW Pipe Weight Chart

The ERW pipe weight chart is a reference table that provides the weight per meter (or per foot) of pipes based on their outer diameter (OD) and wall thickness. This information is crucial for:

  • Project planning and budgeting

  • Transport logistics and load calculations

  • Structural integrity and support system design

  • Material procurement on B2B platforms in India

By using the weight chart, buyers and engineers can make accurate decisions, especially when sourcing materials through B2B sites in India, where specifications and shipping costs are significant factors.


Sample ERW Pipe Weight Chart

Here’s a simplified example of an ERW pipe weight chart for mild steel pipes:

Nominal Pipe Size (inches)

Outside Diameter (mm)

Wall Thickness (mm)

Weight (kg/m)

1

33.4

3.2

2.41

2

60.3

3.65

5.44

3

88.9

219.1

8.0

43.87

Note: The actual weight may vary slightly depending on the grade of steel and manufacturing tolerances.


How Is ERW Pipe Weight Calculated?

The weight of ERW pipes is typically calculated using the following formula:

Weight (kg/m) = (Outer Diameter – Wall Thickness) × Wall Thickness × 0.02466

This formula gives an approximation based on the density of carbon steel (7850 kg/m³). Buyers on B2B sites in India often rely on these standard calculations to compare offers from multiple suppliers and ensure consistency in their sourcing.


Application in B2B Market India

The B2B market in India is rapidly expanding, and ERW pipes form a significant portion of industrial trade. Buyers ranging from infrastructure companies to HVAC contractors depend on accurate weight charts to place bulk orders on platforms like IndiaMART, TradeIndia, and ExportersIndia—leading B2B sites in India. These platforms provide technical data, weight specifications, and pricing details that enable better comparison and informed decision-making.

For instance, if a buyer is looking to source 10,000 meters of 4-inch ERW pipe, they can estimate the total load (16.85 kg/m × 10,000 m = 168,500 kg) and plan logistics accordingly. This clarity in weight estimation is essential for transportation, especially when dealing with large volumes common in the India B2B market.


Final Thoughts

An ERW pipe weight chart is more than just a table—it's a critical planning tool for manufacturers, contractors, and suppliers operating in the industrial sector. Especially within the B2B market in India, where scale and precision matter, understanding pipe weights helps businesses reduce costs, avoid logistical issues, and ensure the structural integrity of their projects.


Whether you are sourcing ERW pipes for infrastructure, mechanical systems, or export, always refer to an updated and manufacturer-specific weight chart. When navigating B2B sites in India, be sure to verify that product listings include accurate weight information and cross-check these figures with industry standards to make the right procurement choices. Pipex.ai, a trusted supplier in the piping industry, ensures that all product listings are detailed with precise specifications to support informed decision-making.
