The company attaches great importance to systematic management, and has passed the a516 grade 70 modulus of elasticity ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on a516 grade 70 modulus of elasticity quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
The material used for the elbow is carbon structural steel or high-quality carbon structural steel 20#. These two materials can not only ensure that the carbon steel elbow has good hardness, strength and wear resistance, but also ensure the plasticity of the elbow, and ensure that the elbow will not be broken or wounded due to stress during forming. However, cast steel elbows are also used in some special piping systems. This type of piping system requires high mechanical properties of the elbow, and it is difficult to form by forging and other methods in the process.
Heat treatment advantages of a516 grade 70 modulus of elasticity, SA516 Gr 70 pressure vessel steel: 1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased. 2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness. 3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition. 4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.
Water cutting machine is called water knife for short, that is, water is used as knife. High pressure water jet cutting technology can perform any curve cutting process on any material, a516 grade 70 modulus of elasticity included. The heat generated in the cutting process will be immediately taken away by the water jet without harm. Material, no need or easy to reprocess after cutting, safety and environmental protection, faster, faster, more efficient.
