The ** of asphalt paint for pipes varies depending on the brand, specification, use and other factors. Generally speaking, the first level of asphalt paint is tens of yuan to hundreds of yuan a barrel. For example, some common civil pipelines, such as water supply and drainage pipelines, gas pipelines, etc., are mainly used to prevent rust and waterproof when brushing asphalt paint, and the first grade of asphalt paint for this kind of pipeline is relatively low, about ten yuan to dozens of yuan per square meter.
For industrial pipelines, such as pipelines in petroleum, chemical, fire protection and other industries, due to their harsher use environment, the performance requirements for asphalt paint are higher, so it will be relatively high, and it may cost hundreds of yuan per square meter.
In addition, for some special-purpose pipelines, such as buried pipelines, deep-sea pipelines, etc., due to their higher requirements for anti-corrosion, waterproofing, wear resistance, etc., the performance of the required asphalt paint is more complex, so it will be higher.
In general, the asphalt paint of pipes varies according to factors such as use, environment, performance requirements, etc., and the specific needs to be determined according to the actual situation. When choosing asphalt paint, you should choose the appropriate asphalt paint according to the use environment, performance requirements and other factors of the pipeline, and consult professional manufacturers or construction teams to obtain more accurate information.
