Q345B Seamless Square Pipe for Machinery Equipment, Galvanized Square Pipe, Corrosion-Resistant

Applications for Seamless Square Pipes

Seamless square tubes are metal tubes with square cross-sections, which have various applications including:

Structural supports and seamless square tubes are commonly used as structural materials for beams, columns, and walls in the construction field, as well as for scaffolding and formwork.

Fluid conveyance; Seamless square tubes are used for conveying low-pressure fluids such as oil, gas, and water due to their ability to withstand internal or external radial pressure, and their lower hardness and fatigue resistance.

Mechanical manufacturing, seamless square tubes are used for producing various mechanical components and equipment, such as bearing shells and jack sleeves.

In addition, seamless square tubes are widely used in bridges, railways, vehicles, ships, metallurgical industry, agricultural vehicles, greenhouses, automotive industry, highway guardrails, container frames, furniture, decoration, and steel structure fields.

The advantages of seamless square tubes include high strength, corrosion resistance, excellent machinability, attractive appearance, and high reliability. They typically feature a hollow cross-section and are manufactured through extrusion or cold drawing processes. Compared to traditional welded square tubes, seamless square tubes perform better under pressure.
