The concret pump pipes is a new type of construction engineering accessory product that appears at the same time as the concrete pump. The appearance of the concret pump pipes greatly improves the efficiency of the construction. It requires a manual bucket or a bucket for labor or crane. The mode of operation was changed to the rapid transfer of concrete to the place where it was poured, which increased the construction efficiency by nearly a hundred times.
concret pump pipess are generally divided into three types, 125 and 150 and 80, and each of them has a high pressure and a low pressure. The low pressure model weld flange of the 125 type concret pump pipes is Φ148mm, and the high pressure tube weld port flange is Φ157mm; the low pressure type of the 150 type concret pump pipes is the pipe with the outer diameter of Φ159, and the high pressure is the pipe with the outer diameter of Φ168. The pipe head of the concret pump pipes is a specially processed pipe joint that is connected to the pipe body by welding, and the connection of each pipe is connected by a pipe card processed by a precision casting process.
According to the scope of use, the concret pump pipes is divided into two types: the concret pump pipes and the ground concret pump pipes. The concret pump pipes includes the boom tube, the hinge elbow, the reducer and the elbow, and is cast from cast steel. The straight tube material is 45mn2. The concret pump pipes is made of ordinary 20# carbon steel, which is processed by fluid tube or straight seam tube.
If the concret pump pipes is subjected to conventional welding operations, many of the pipes whose inner walls have been treated with corrosion protection will be destroyed. Therefore, the specification stipulates that galvanized pipes, plastic-lined steel pipes, steel-plastic composite pipes, etc. shall not be welded or flanged, otherwise secondary treatment is required. His connection method has a unique flexibility, which makes the pipeline resistant to vibration, shrinkage and expansion. Compared with welding and flange connection, the stability of the piping system is increased, which is more suitable for temperature changes, thus protecting the pipeline. Pipeline valve components also reduce the damage to the structural components caused by pipe stress.
