Classified details for hollow steel pipe

As for versatile and efficient form for construction and mechanical functions, we know that hollow section tube from  scaffloding steel pipe  to galvanized steel pipe has an important role in these project. We can take a view for Tianjin Xinyue Steel Group's hollow section tube today. Scaffolding Tube: Use: Scaffolding is a temporary structure used to support people and material in the construction or repair of buildings and other large structures. Material Storage Racks, Pallets, Hydraulic Platforms, Trusses, Columns, Purlins, Greenhouse, Stands Towers, Agricultural Equipment Standard: BS 1139, BS1387-1985, EN 39, EN10219, JIS G 3444 Certificate: EN10217, EN10219, API 5L PSL1/ PSL2, API 5CT Out Diameter: 27mm, 38mm, 42mm, 48.3mm-48.6mm Wall Thickness: 2.0mm, 2.5mm, 2.75mm, 3.0mm, 3.25mm, 3.85mm, 4.0mm Galvanized Steel Pipe: Type: 1.

Mechanical properties of square hollow section

1. The analysis of hardness of square hollow section Hardness is a measure of softness and hardness of metal materials. The most commonly used hardness measurement in the production is the press method, which uses indenters with a certain geometric shape to press the surface of tested metal materials and obtains its hardness based on the pressing degree. The commonly used methods are Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC), Vickers hardness (HV) and so on. 2. The analysis of plasticity of square hollow section Plasticity refers to the plastic deformation(permanent deformation) of metal material under the action of the load, which can not be damaged. 3. The analysis of fatigue of square hollow section The strength, plasticity, and hardness which we discussed above are the mechanical properties of the metal under static load. In fact, many machine parts are working under cyclic loading, which will lead to fatigue. 4. The analysis of impact toughness of squ...
