High strength bolt tester
Steel structure engineering is a structure mainly made of steel, mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. The components or parts are usually connected by welds, bolts or rivets. One of the main types of building structures. Because of its light weight and simple construction, it is widely used in large-scale factories, stadiums, super high-rises and other fields. Steel structure engineering quality inspection mainly includes: physical and chemical inspection of raw materials (elemental analysis, mechanical properties), non-destructive inspection of welded joints (radiography, ultrasound, magnetic particle and penetration), anti-corrosion and fireproof coating inspection (thickness, adhesion), deformation inspection (Deflection, perpendicularity, plane bending), the torque coefficient of high-strength bolts and the anti-slip coefficient of the friction surface.
Including raw material and welded joint mechanical performance testing (tension, bending, impact, hardness) fastener mechanical performance testing (wedge load, torque coefficient, axial force, etc.), chemical composition analysis of testing raw materials, non-destructive testing of welded joints, friction surface resistance Slip coefficient, painting, deformation detection of steel grid structure, etc.
