Explain the advantages of clamp pipe connection in detail

1. Conducive to construction safety　

Adopting the clamp pipe connection technology, only the cutting machine, the rolling groove machine and the handle for the button bolt are needed on site, and the construction organization is convenient. However, welding and flange connections require complicated power cables, cutting tools, welding machines, oxygen and acetylene gas cylinders, etc., which brings complexity to the construction organization, and there are also hidden dangers of electric leakage and fire. . At the same time, the 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. In addition, welding and flange connection inevitably require long-term and high-strength high-altitude operations, and production safety accidents are also prone to occur.

2. The original characteristics of the pipes connected by the clamp pipe fittings are not affected

For the connection of clamp pipe fittings, a clamp is squeezed out with a roll groove machine only on the face of the connected pipe without damaging the inner wall structure of the pipe. This is the unique technical advantage of clamp pipe fittings. If the traditional welding operation is adopted, many pipes whose inner wall is used as the corrosive layer of the ground font 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. Simple operation (Guide: Three basic methods of preventing loosening of threaded fastener connections)

The connection of the clamp pipe fittings to the playground is 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 way. It only takes a few minutes to connect a pipe fitting, which greatly simplifies the technical difficulty of the on-site courtyard playground, saves man-hours, thereby also stabilizes the quality of the project and improves 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 takes time, the operation of workers is difficult, and there is welding fume pollution. Due to differences in operating space and welding skills, welding quality and appearance are difficult to achieve satisfactory results. Thereby affecting the overall quality of the project. In addition, because the clamp pipe fittings are finished parts, the operating space required on site can be installed against the corner of the wall, and the difficulty of manipulating is greatly reduced, thus saving the floor space and beautifying the effect of pipeline installation.

4. Economic analysis

Because the clamp pipe fittings are connected easily, labor and time are saved, so they have good economic benefits. Many articles have done economic analysis and believe that the use of clamp connection, the price of individual accessories of the clamp is higher, but the overall benefit of the installation of the entire pipe network is higher than that of flange connection. When comparing the articles, the method is connected according to the second galvanizing treatment (this is also necessary according to the requirements of the specification). Below, the author extracts the comparison results of the article 'Trial Discussion on Clamp Joint Piping System' in the fifth issue of 2001 in 'Water Supply and Drainage' magazine for readers' reference. See Table 1 for details.

5. The system has good stability and easy maintenance

The connection method of clamp pipe fittings has unique flexible characteristics, which makes the pipeline anti-vibration, anti-shrinkage and expansion ability. Compared with welding and flange connection, the stability of the pipeline system is increased, and it is more suitable for temperature changes. , So as to protect the pipeline rafts, and reduce the damage of the pipeline stress to the structural parts.

　　Since the connection operation of the clamp parts is simple, the required operation space becomes smaller, which brings many convenient conditions for future maintenance. When the pipeline needs to be repaired or replaced, only need to loosen the two clamps to find, rotate and modify a section of pipeline at will. There is no need to damage the surrounding walls, reducing maintenance time and maintenance costs.
