Grooved bellows are a new type of steel pipe connection compensator, which has many advantages. Pipeline groove connection technology rose in the United States in the 1950s and was introduced into China in the 1990s. Since then, because of its convenient installation, reliable quality, economic and environmental protection and other outstanding advantages, it has been quickly accepted and promoted by the domestic market. Under the guidance of national laws and policies, this technology has been widely used in fire water supply, domestic water supply, central air conditioning, sewage treatment, petrochemical industry, thermoelectricity and military industry, and gradually replaced the two traditional pipeline connection modes of flange and welding, becoming the first technology of gas and liquid pipeline connection. Next, Hongsheng will show you five advantages of grooved bellows connection: 1. Simple operation Connection operation of grooved pipe fittings is very simple, without special professional skills, ordinary workers can operate after simple training. Because the product has incorporated a large number of fine parts into the finished product in a factory way. A pipe connection only takes a few minutes, which simplifies the technical difficulty of field operation to the greatest extent, saves working time, stabilizes engineering quality and improves work efficiency. This is also the general direction of the development of installation technology. Because the ditch is a finished product, the operation space needed on site is small, and the installation can be realized by increasing the angle of relief. The difficulty of operation is greatly reduced, which saves the area occupied and beautifies the effect of pipeline installation. The traditional flange and welding connection method not only requires the corresponding skills of welding workers, but also consumes a lot of time, the operation of workers is difficult and will produce pollution. Due to the difference of operation space and welding skills, it is difficult to achieve satisfactory results in welding quality and appearance, thus affecting the overall effect of the project. 2. The original characteristics of pipelines are not affected. The connection of grooved pipe fittings only extrudes a groove on the outer surface of the connected pipe with a grooving machine, without damaging the inner wall structure of the pipe. This is the unique technical advantage of grooved pipe fittings connection. If the traditional welding operation is adopted, many pipelines with anticorrosive coating on the inner wall will be damaged. Therefore, the specification stipulates that galvanized pipes, Village plastic pipes, steel-plastic composite pipes and so on must not be welded and flanged connection, otherwise secondary treatment is required. 3. Favorable to Construction Safety The grooved pipe fittings connection technology is adopted, and only the handles for cutting machine, grooving machine and button bolt are needed on site, so the construction organization is convenient. The use of welding and flange connection requires complex power cables, cutting tools, welding machines, oxygen and acetylene cylinders, which brings complexity to the construction organization, and there are also potential risks of leakage and fire. At the same time, the welding slag produced by welding and gas cutting inevitably falls into the pipeline, which is prone to pipe valves and even equipment blockage in use, and also pollutes the water quality in the pipeline. In addition, welding and flange connection inevitably require long time and high-intensity high-altitude operation, and are also prone to production safety accidents. 4. The system is stable and easy to maintain. The connection mode of grooved pipe fittings has unique flexible characteristics, which makes the pipeline have the ability of anti-vibration, anti-shrinkage and expansion. Compared with welding and flange connection, the stability of pipeline system increases, and it is more suitable for temperature change, thus protecting pipeline valve fittings and reducing the damage of pipeline stress to structural parts. Because the connection of grooved pipe fittings is easy to operate, the required operating space becomes smaller, which brings many convenient conditions for future maintenance. When the pipeline needs to be repaired and replaced, only two clamps can be loosened to replace, rotate and modify a section of pipeline at will. There is no need to destroy the surrounding walls, which reduces the maintenance time and cost. 5. Economic Analysis The connection of grooved pipe fittings is easy to operate and saves labor and time, so it has good economic benefits.
