Structural Pipe vs Fluid Pipe: What are the Key Differences?

Table of Contents

  1. Definition of structural tube and fluid tube

A structural pipe is a type of pipe that is mainly used to withstand pressure, tension or bending forces. It is mainly made of steel or other materials and is commonly used in areas such as the structure of buildings, bridges, tunnels, and transmission lines. A fluid pipe, on the other hand, is a type of pipe used to transport fluids or gases, and is commonly used in industrial, civil, and agricultural fields.

Second, the shape of structural tubes and fluid tubes

Structural tubes are usually round or square, while fluid tubing can be round, square, rectangular or other shapes depending on specific needs. In addition, because the structural tube needs to withstand a large load, its thickness and diameter are generally relatively large, while the fluid tube is usually made of thinner material, because it mainly needs to consider the fluid’s transportation smoothness.

Third, the material difference between structural tube and fluid tube

Structural pipes are generally made of high-strength steel or other alloy materials to ensure their load-bearing capacity. The fluid tube can use more types of materials, such as iron, copper, plastic, fiberglass, etc., and the specific choice also needs to be determined according to the type of fluid transported and the pressure size.

Fourth, internal structural differences

The internal design of structural pipes is usually relatively simple, usually consisting of one or several layers of steel. Fluid tubing, on the other hand, needs to consider the flow characteristics of the fluid, so the internal design is more complex. For example, in order to reduce the friction and resistance of the fluid, some fluid pipes use smooth inner walls, while for pipes transporting high-temperature liquids or gases, high-temperature pressure-resistant materials need to be used to manufacture the inner walls.

  1. Differences in applicable fields

Due to the different design purposes of structural tubes and fluid tubes, there are also differences in the fields in which they are applicable. Structural pipes are mainly used in building structures, bridges, tunnels and transmission lines, while fluid pipes are suitable for various fields of transporting fluids or gases, such as oil pipelines, water supply pipelines, gas transmission pipelines and so on.

In summary, there are differences between structural tubes and fluid tubes. Understanding the differences between the two can help us better understand their respective characteristics and areas of application, so that we can better apply them.
