The original characteristics of the pipeline will not be affected by the 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. This is a unique technical advantage of 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. shall not be welded and flanged. Otherwise, secondary treatment is required to facilitate construction safety. Groove pipe connection technology is used, and only cutting machines and roll groove machines are required on site. It is convenient to organize the construction by the handle used for tightening the bolts. However, the use of welding and flange connection requires complicated power cables, cutting tools, welding machines, oxygen and acetylene gas cylinders, etc. This brings complexity to the construction organization, and there are also hidden dangers of leakage and fire. .
At the same time, the welding slag produced by welding and gas cutting will inevitably fall into the pipeline, and it is easy to cause pipeline valve parts and even equipment blockage during use. Because the grooved pipe fittings are easy to connect and operate, the required operating space becomes smaller. This is a future Maintenance brings many conveniences. 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.
