Groove pipe fitting connection technology, also known as clamp connection technology. The design specification of automatic sprinkler system proposes that the connection of system pipes should be made of groove connectors or wire buckles and flanges; Pipes with diameters equal to or greater than 100mm in the system shall be connected by flanged or grooved connectors in sections.

The application of groove pipe fitting connection technology makes the complicated pipeline connection process simple, fast and convenient. This is a big step forward for pipe connection technology.

The advantage of the pipe with groove connection

1. Simple operation

The connection operation of the trench pipe fitting is very simple, without special professional skills, ordinary workers can operate after simple training. This is because the product has incorporated a lot of fine technical parts into the finished product in a factory way. It only takes a few minutes to connect a pipe fitting, which simplifies the technical difficulty of field operation to the maximum extent, saves man-hours, and thus stabilizes the project quality and improves the work efficiency. This is also the general direction of installation technology development.

However, the traditional welding and flanged pipe connection method not only requires skilled welding workers, but also takes time, and it is difficult for workers to operate, and there is welding smoke pollution. Due to the differences in operating space and welding skills, it is difficult to achieve satisfactory results in welding quality and appearance, thus affecting the overall quality of the project.

In addition, because the trench pipe fittings are finished products, the operation space required by the site is small, can really achieve the wall by the corner installation, the difficulty of operation is greatly reduced, thus saving the area, beautify the effect of pipeline installation.

2. The original characteristics of the pipeline are not affected

Groove pipe fitting connection, only on the outer surface of the connected pipe with a groove extrusion machine, without destroying the inner wall structure of the pipe, which is the special technical advantages of groove pipe fitting connection. Many pipes with corroded walls would have been damaged by conventional welding. Therefore, the specification stipulates that galvanized pipe, plastic steel pipe lining, steel-plastic composite pipe, etc., shall not use welding and flange connection, otherwise it needs secondary treatment.

3. Conducive to construction safety

With the groove pipe fitting connection technology, only the cutting machine, the groove roller and the handle for the button tightening bolt are needed on site, which makes the construction organization convenient. The use of welding and flange connection, it is necessary to equip with complex power cables, cutting machines, welding machines and oxygen and acetylene cylinders, which brings complexity to the construction organization, and there are also leakage and fire hazards. At the same time, welding slag generated by welding and gas cutting will inevitably fall into the pipeline, which is easy to produce pipeline valve parts and even equipment blockage in use, and also pollute the water quality in the pipe.

In addition, welding and flange connection inevitably need a long time and high intensity of high altitude work, also prone to production safety accidents.

4. The system stability is good, easy maintenance

The groove pipe fitting connection has unique flexible characteristics, so that the pipeline has the ability to resist vibration, contraction and expansion, compared with welding and flange connection, the stability of the pipeline system is increased, more suitable for temperature changes, so as to protect the pipeline valve, but also reduce the damage to the structural parts of the pipeline stress.

Due to the simple operation of groove pipe fitting connection, the operation space required is smaller, which brings many convenient conditions for future maintenance. When the pipeline needs maintenance and replacement, just loosen the two clips to change, rotate and modify a section of the pipeline. Do not need to damage the surrounding wall, reduce the maintenance time and maintenance cost.

5. Economic analysis

The connection of the trench pipe fitting is simple and saves labor and time, so it has good economic benefits. Many articles have done economic analysis, believe that "with clamp connection, although the price of a single part of the clamp is higher, but the overall efficiency of the pipe network installation is higher than the flange connection". In the comparison of the article, the flange connection is treated by secondary galvanizing (it is also necessary to do according to the specification requirements).

Cangzhou Shenlong Pipe specializes in the production of steel pipe and pipe fittings, including elbow, tee, reducer, etc., the product quality is guaranteed, can arrange SGS inspection, is the first choice for some large projects.
