1. Easy to operate
The connection operation of groove fittings is very simple and does not require special professional skills. Ordinary workers can operate it after simple training. This is because the product has incorporated a large amount of sophisticated technical components into the finished product in a factory like manner. A pipe fitting connection only takes a few minutes, simplifying the technical difficulty of on-site operations to the greatest extent possible, saving time, and thus stabilizing the quality of the project and improving work efficiency. This is also the overall direction of installation technology development.
The traditional pipeline connection method of welding and flange connection not only requires skilled welding workers, but also is time-consuming, difficult for workers to operate, and prone to welding smoke pollution. Due to differences in operating space and welding skills, it is difficult to achieve satisfactory results in welding quality and appearance, which affects the overall quality of the project.
In addition, as the groove fittings are finished products, the required operating space on site is small, which can truly achieve installation against walls and corners, greatly reducing the difficulty of operation, thereby saving floor space and beautifying the effect of pipeline installation.
2. The original characteristics of the pipeline are not affected
The connection of groove fittings is a unique technical advantage of using a groove rolling machine to squeeze a groove on the outer surface of the connected pipeline without damaging the inner wall structure of the pipeline. If traditional welding operations are used, many pipelines with anti-corrosion coatings on the inner walls will be damaged. Therefore, the regulations stipulate that galvanized pipes, plastic lined steel pipes, steel plastic composite pipes, etc. shall not be welded or flanged, otherwise secondary treatment is required.
3. Beneficial for construction safety
By using groove fitting connection technology, only cutting machines, groove rolling machines, and handles for tightening bolts are needed on site, making construction organization convenient. However, using welding and flange connections requires complex power cables, cutting tools, welding machines, and oxygen and acetylene cylinders, which brings complexity to the construction organization and also poses risks of electrical leakage and fire hazards. The welding slag generated by both welding and gas cutting inevitably falls into the interior of the pipeline, which can easily cause blockage of pipeline valves and even equipment during use, and also pollute the water quality inside the pipeline.
In addition, welding and flange connections inevitably require long-term high-intensity high-altitude operations, which can also easily lead to production safety accidents.
4. Good system stability and easy maintenance
The connection method of groove fittings has unique flexibility characteristics, which make the pipeline have the ability to resist vibration, shrinkage and expansion. Compared with welding and flange connection, the stability of the pipeline system is increased, which is more suitable for temperature changes, thus protecting the pipeline valves and reducing the damage of pipeline stress to structural components.
Due to the simple operation of connecting groove fittings, the required operating space is reduced, which brings many convenient conditions for future maintenance. When the pipeline needs to be repaired or replaced, simply loosen the two clamps to replace, rotate, or modify a section of the pipeline at will. No need to damage the surrounding walls, reducing maintenance time and costs.
5. Economic analysis
The connection operation of groove fittings is simple, time-saving, and therefore has good economic benefits. Many articles have conducted economic analysis, stating that "using clamp connections, although the individual component price of the clamp is higher, the overall benefits of installing the entire pipeline network are higher than flange connections". When comparing in the article, the flange connection is treated with secondary galvanizing (which is also necessary according to the specifications).
