Abrasion resistance of concrete pump pipe transport of concrete is used in construction industry, concrete pump pipe service life is longer is wearable strength is stronger, wear-resisting pump pipe made of special material of steel tube, through arm inside hardening, infiltration of carbon processing, flange bushings hardness of 58 and 60 degrees, the service life of the pipeline for 3 to 5 times, the user to save the time and cost, dispense with the trouble that often in tube, improve the production efficiency.
Pump pipe is generally divided into 125 and 150 and 80 three kinds, and these two kinds of high pressure and low pressure respectively. 125 type pump pipe of low pressure model for the outer diameter is Φ 133 pipes, high pressure pipe diameter is Φ 140; 150 type pump pipe of low pressure model for the outer diameter is Φ 159 pipes, high pressure pipe diameter is Φ 168. The pipe head of the pump pipe is a specially processed pipe joint, which is connected with the pipe body by welding. The connection of each pipe is connected by the pipe clip processed by the investment casting process.
Concrete wear-resisting pump pipe is divided into two types of truck pump pipe and ground pump pipe according to the scope of use. Truck pump pipe includes boom pipe, hinge elbow, reducer pipe and elbow pipe, which are made of cast steel and the straight pipe material is 45mn2. Ground pump pipe is ordinary 20# carbon steel, by fluid pipe or straight pipe, processed.
