Constant force spring hanger, variable spring hangers, chemical spring hanger Contact: Ma Yuanyuan Contact: 18,732,703,585 QQ: 619688609@qq.com designed in accordance with the principles of the torque balance. In the displacement range of the predetermined load, the load torque and the spring torque is always balanced. Therefore, the with constant hanging support piping and equipment shifted, can obtain a constant supporting force, not to piping and equipment additional stress. The hanging constant need to reduce the displacement and stress is generally used, such as power station boiler body, power plant steam, water, smoke duct burner suspension part, and petrochemical equipment and other needs of displacement and stress reduction.
