Concrete pump pipe fittings connection characteristics

Concrete pump pipe connection has a unique flexible characteristics of the pipeline with anti-vibration, anti-shrinkage and expansion of capacity, compared with the welding and flange connection, pipe system stability increases, more suitable for temperature changes, thus protecting The pipeline valve, also reduces the pipeline stress damage to the structure. Concrete pump pipe fittings connected to the outer surface of the pipe is connected with a groove rolling machine squeezed out a groove, without damaging the pipe wall structure, which is concrete pump pipe fittings unique technical advantages. With traditional welding operations, many of the inner walls of the pipeline have been destroyed. Therefore, the provisions of norms galvanized pipe, lined plastic pipe, steel-plastic compope, etc. are not allowed to use the welding and flange connection, or the need for secondary trsite pieatment. The use of concrete pump pipe connection technology, the scene only need cutting machine, roll groove machine and button bolts with handy, construction and organization convenience. The use of welding and flange connection, you need to be equipped with complex power cables, cutting equipment, welding machines and oxygen and acetylene cylinders, which gives the construction organization has brought complexity, and there are also risks of leakage and fire risk . At the same time welding and gas cutting produced by welding slag, inevitably fall into the pipeline, the use of pipe valves and other equipment is likely to cause blockage, but also pollution of the water pipe. Due to the simple operation of the concrete pump pipe connection, the required operating space becomes smaller, which brings many convenient conditions for future maintenance. When the pipeline needs repair and replacement, simply release the two clamps can be arbitrarily replaced, rotate, modify a pipeline. Without damage to the surrounding walls, reducing maintenance time and maintenance costs.
