Square tubes are made of steel. If they are exposed to rain, they will definitely rust. Therefore, they should not be exposed to rain when stored.

The five key stages for expanding longitudinally welded pipes, from initial rounding to final unloading, ensuring high-quality steel pipe production.

The key factors influencing high-frequency longitudinal welded pipe technology for enhanced product quality and efficiency.

Enhancing the durability and longevity of welded steel pipes for fluid transportation with adherence to the ASTM A53 galvanizing standard.

In high-frequency straight seam welded pipes, crack manifestations include long cracks, local periodic cracks and irregular intermittent cracks. There are also some steel pipes with no cracks on the surface after welding, but cracks will appear after flattening, straightening or hydrostatic testing.

Straight seam steel pipes can be divided into high-frequency straight seam steel pipes and submerged arc welded straight seam steel pipes according to the production process. Let me explain to you the most common forming processes in submerged arc welding steel pipes and straight seam forming processes.

With the advancement and vigorous development of advanced technology, welded pipe technology has achieved large-scale leap-forward development in the past decade of this century, which directly drives the production efficiency of welded pipes and the quality of the welded pipes themselves. Great progress has been made.

Steel support formwork systems are partly made of steel and partly of wood as supporting members. In some cases, primary load-bearing members are supported by steel and secondary or auxiliary load-bearing members by timber.

First of all, let’s first understand the definition of steel structure tube trusses. In steel structure engineering, tube trusses refer to lattice structures that connect components together through riveting, bolts or welding. The pipe truss included specifically refers to a grid structure composed of steel pipes connected to each other at the ends. The rods in the structure are all round pipe rods.

Crown beams, purlins, horizontal supports, steel columns and column piles are the basic components of the internal support system.
