Product Information

In 1919, Lieutenant Ernest tribe found that mechanical joints could be used to connect pipes quickly and safely, and Victaulic immediately created grooved connection. For grooved connection, after the joints at the flat ends of two pipes are processed into ring grooves, clamps are used to clamp the ring grooves of the pipes to ensure that the pipes are not pulled apart when there’s axial force. There is also a rubber ring in the clamp, which is C-shaped. After the bolt of the clamp is tightened, the rubber ring is squeezed to form a sealing effect. We recommend grooved connection for DN100-200 size pipes, which is also convenient and quick, and does not need special technology.

The grooved pipe fittings include two categories of products:

1) Fittings that act as connecting seals include rigid joints, flexible joints, mechanical tees and grooved flanges.

2) There are elbow, three-way tee, four-way cross, reducer, blind flange and so on.

The grooved fittings which play the role of connecting and sealing are mainly composed of three parts: sealing rubber gasket, clamp and locking bolt. The rubber sealing ring located in the inner layer is placed on the outside of the connecting pipe, which coincides with the pre-rolled groove. Then the clamp is fastened on the outer part of the rubber ring, and then fastened with two bolts. Because the rubber sealing ring and clamp adopt special sealing structure design, the groove connection has good sealing performance, and with the increase of the fluid pressure in the pipe, its sealing performance increases accordingly.

 

Features


Simple operation: Connection operation of grooved pipe fittings is very simple, without special professional skills, ordinary workers can operate after simple training. This is because the products have incorporated a large number of fine technical parts into the finished products in a factory way. A pipe connection only takes a few minutes, which simplifies the technical difficulty of field operation to the greatest extent and saves man-hour, thus stabilizing the quality of the project and improving the work efficiency. This is also the general direction of installation technology development.

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, plastic-lined pipes, steel-plastic composite pipes and so on must not be welded and flanged connection, otherwise secondary treatment is required.

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.

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.
