DN125 Putzmeister concrete pump spare parts This is our patent product, our alumina and zirconia ceramic tiles are super abrasive. We use our abrasion resistant ceramic tile lined into the inner wall of the seamless carbon steel concrete pump pipes. We are able to provide all different types of ceramic lined concrete pumping pipes and special installations. We can also make the standard and nonstandard ceramic lined concrete pump pipes and elbows according to customers’requirement. The advantages of alumina ceramic lined concrete pump pipe 1. The weight is lighter than normal pipe. 2. Competitive and reasonable price 3. Saved maintenance time and expenditures 4. KCPP pipes can transport the concrete up to 80000 cube meters. It is five times than normal manganese steel pipes.
5. The inner side material is the high alumina ceramic, Hardness up to 88HRA, next to the diamond, because of the smooth surface ,it can avoid the jam during the transport of concrete.
6. The outside material is the seamless steel, it has been tested safety.
7. It is standard flange connection, easy for installation.
8. It can reduce the repairing frequency as well as reduce the operators’ working strength. Specifications: Parts No.: KCPP Size: DN125-5 1/2" Radius: 240-500mm Degree: 15-90 Deg Length:500-3000mm End collars: 148mm Materials: Alumina and zirconia ceramic lined seamless carbon steel elbow Concrete pumping capacity: Up to 80000 Cubic meter concrete Other sizes and ends upon request Reporting for the wear resistant abilities
Item | Conditions | Result |
Rotate speed | Loading | Time | Abrasion ratio | Abrasion volume |
1.high-chrome | 800r/min | 76N | 30min | 0.1534 | 0.0038 |
2.Manganese | 800r/min | 76N | 30min | 0.2945 | 0.0059 |
3.Kingcera abrasion resistant ceramic | 800r/min | 76N | 30min | 0.0196 | 0.0004 |
In the condition of P=76N, n=800round/min, t=30, calculating in abraded mass, the abrasion resistant ability of Kingcera ceramic is about 9.5 times than the high chrome , 15times than the manganese steel. The technical specifications ceramic lined concrete pump pipe
