The Concrete Pump Pipe is made of special quality steel which is quenched and carried out carburizing chemical treatment on the inner wall.
The concrete pump straight pipe is made of special alloy steel ( 45Mn2). The inner pipe wall is case hardened by CNC high-frequency induction hardening machine. The inner pipe wall becomes a wearable layer with high hardness.
The concrete pump pipe is a new type of construction engineering accessory product that appears at the same time as the concrete pump. The appearance of the pump tube 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 pipes 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 pump tube is Φ148mm, and the high pressure tube weld port flange is Φ157mm; the low pressure type of the 150 type pump tube 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 pump tube 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 pump tube is divided into two types: the pump tube and the ground pump tube. The pump tube 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 pump tube is made of ordinary 20# carbon steel, which is processed by fluid tube or straight seam tube.
Main use of concrete pump pipe
Social stability, the development of the motherland, and the improvement of housing conditions. The building is getting higher and higher, and the construction difficulty is getting bigger and bigger. Therefore, the pump tube has appeared, greatly improving the building shortcut and convenience.
The main purpose of thepump tube : construction, bridge construction, as long as the concrete is used, the pump tube is generally used, the pump tube is the special steel pipe for conveying concrete.The pump tube is usually three meters long and one intermediate tube card is connected. The pump tube of the appropriate size can be selected according to the pressure and diameter of the pump. It can easily hit the concrete to the floor of more than 30 stories, which greatly improves the work efficiency and construction quality. However, the pressure on the pump tube of such a high floor is also huge. Therefore, when selecting the pump tube, we must look for the pump tube produced by the regular manufacturer. For example, the Weiwei pump tube produced by our factory all adopts Angang, Fengbao, and the production. Thick wall steel pipe. The hoop is made of forging technology. Two-welding single-sided welding double-sided forming welding technology. Ensurethe wear-resistant pressure bearing performance of Weiwei brand pump tube during use. According to the on-site inspection, the service life of Weiwei brand pump tube (the number of concrete conveyed by the factory) produced by our factory is several times that of ordinary small manufacturers.
