Advantages of grooved pipe connection
1. Simple operation
The connection operation of grooved pipe fittingsis very simple, no special professional skills are required, and ordinary workers can operate it after simple training. This is because the product has incorporated a large number of fine technical parts into the finished product in a factory manner. It only takes a few minutes to connect to a pipe fitting, which greatly simplifies the technical difficulty of the on-site operation and saves man-hours. Thereby stabilizing the quality of the project and improving work efficiency. This is also the overall direction of the development of installation technology.
The traditional pipe connection method of welding and flange connection not only requires welding workers with corresponding skills, but also is time-consuming, difficult for workers to operate, and pollution from welding fumes. Due to differences in operating space and welding skills, welding quality and appearance are difficult to achieve satisfactory results, which affect the overall quality of the project.
Also, because grooved pipe fittings are finished parts, the operation space required on-site is small, which can be installed against the wall and the corner, and the operation difficulty is greatly reduced, thus saving the floor space and beautifying the effect of pipeline installation.
2. The original characteristics of the pipeline are not affected
Grooved pipe connection, only a groove is extruded on the outer surface of the connected pipe with a roll groove machine without destroying the inner wall structure of the pipe, which is a unique technical advantage of a grooved pipe connection. If the traditional welding operation is adopted, many pipes with anti-corrosion coating on the inner wall will be damaged. Therefore, the specification stipulates that galvanized pipes, plastic-lined steel pipes, steel-plastic composite pipes, etc. must not be welded and flanged, otherwise secondary treatment is required.
3 Conducive to construction safety
Using grooved pipe connection technology, only the cutting machine, rolling groove machine, and handle for button bolts are needed on-site, which is convenient for construction organizations. However, the use of welding and flange connection requires complicated power cables, cutting tools. Welding machines and oxygen and acetylene gas cylinders, which brings complexity to the construction organization, and there are also the hidden danger of leakage and fire. At the same time, welding slag produced by welding and gas cutting inevitably falls into the pipeline, and it is easy to cause pipeline valve parts and even equipment blockage during use, which also pollutes the water quality in the pipeline.
Also, welding and flange connection inevitably requires long-term high-strength high-altitude operations, and production safety accidents are also prone to occur.
4 Good system stability and easy maintenance
The grooved pipe connection has unique flexibility characteristics so that the pipeline can resist vibration, shrinkage, and expansion. Compared with welding and flange connection, the stability of the pipeline system is increased, and it is more suitable for temperature changes, thereby protecting The pipeline valve parts are also reduced, and the damage of the pipeline stress to the structural parts is also reduced.
Because grooved pipe fittings are easy to connect and operate, the required operating space becomes smaller, which brings many convenient conditions for future maintenance. When the pipeline needs to be repaired and replaced, a section of the pipeline can be replaced, rotated, or modified at will by loosening the two clamps. There is no need to damage the surrounding walls, reducing maintenance time and maintenance costs.
5 Economic analysis
Because grooved pipe fittings are easy to connect and save labor and time, it has good economic benefits. Many articles have done an economic analysis and believe that "using clamp connection, although the price of a single part of the clamp is higher, the overall benefit of the installation of the entire pipe network is higher than that of the flange connection". When comparing the article, the flange connection is treated with secondary galvanizing (this is also necessary according to the specification).
