What is the typical wall thickness of welded steel pipes?

The wall thickness of welded steel pipes typically comes in various specifications, depending on factors such as their application, design requirements, and the pressure they will withstand.

Generally, in building structures and ordinary industrial pipelines, the commonly used wall thickness of welded steel pipes is between 2.5mm and 10mm. For example, welded steel pipes used in general building water supply and drainage systems may have a wall thickness of around 3mm to 6mm, which meets basic strength requirements while also being economical.

For high-pressure or special applications, the wall thickness of welded steel pipes will increase accordingly. For instance, in the petrochemical industry, welded steel pipes transporting high-pressure media may have a wall thickness of 12mm or even thicker to ensure pipeline safety and reliability.

In some lightweight structural or decorative applications, the wall thickness of welded steel pipes may be relatively thin, approximately 1.5mm to 2mm. However, this needs to be selected appropriately based on specific circumstances to avoid affecting performance due to excessively thin wall thickness.

In summary, there is no fixed standard value for the wall thickness of welded steel pipes. Instead, the design and selection are based on different application scenarios and requirements to meet the needs of various engineering and production processes.
