The spray painting of constant force spring support and hanger is based on the on-site use conditions, roughly including anti-corrosion paint, insulating paint, conductive paint, and heat-resistant paint. The paint used for indoor and outdoor pipe support and hanger is different. It is sprayed evenly on the surface of the object, which is water-resistant, oil-resistant, and dries quickly. The paint quality of the constant force spring support and hanger working outdoors should be good. After being washed by rain, there should be no paint falling off. When spraying paint, the surface of the support and hanger should be polished with fine sand and there should be no stains, which will affect the spraying effect. If the support and hanger is used in offshore oil, it should be well treated with anti-corrosion and moisture-proof treatment. After the surface is polished smooth, according to the selection of different types of paint, the two can be mixed and blended or separately prepared. First apply low-grade paint, spray one by one, and multi-layer protection. There are pits and uneven places on the surface of the constant force spring support and hanger. To maintain the smoothness of the object, putty is applied on the surface, and then low-grade paint and paint are applied after smoothing. As a pipe support, the constant force spring hanger is usually painted in medium gray.
When choosing the color, you can choose according to the style of the pipeline at the project site or the construction requirements, with coordination and beauty as the main considerations. The spring pressure of the working part of the constant force spring hanger is also basically constant. If you want to pass through this area continuously, this boundary force will become the continuous force of the elasticity. When calculating the restoring force during deformation, if it is regarded as a simple working force, it is also the reason why the constant force spring shows amazing working force. Pipeline connectors or directly use the spring torque calculation, the result is several times smaller than the measured force. In this complex deformation, h/D is not accurate. This is exactly the reason why the constant force spring hanger (referred to as constant hanger) is designed according to the principle of moment balance. Under the permitted load displacement, its load torque and spring torque remain balanced. It is suitable for pipelines and equipment with thermal displacement in industry, and can obtain constant support force, so it will not bring additional stress to pipelines and equipment.
