Elbow-DN125 x R275 x90D
Service life: 25,000-35,000CBM
Material: Carbon steel
Product profile: The double layer concrete pump elbow is developed by ourselves through new technology and process.
Characteristic: the inner layer of this concrete pump elbow undergoes heat treatment, and then the rigitiry can reach 62-65HRC
Characteristic: the outer layer of the concrete pump elbow possess good toughness properties to protect the inner layer, so the security of the elbow is improved
Life: the experiment done abroad shows that the life of our concrete pump elbow can reach 35,000-50,000cbm, got the customers’ praise
Beside the double layer concrete pump elbow, we produce all kinds of concrete pump parts, straight pipe hose flange coupling and so on
Upper and lower two half parts. According to the failure analysis of the bending pipe, the back of the bending pipe is the most serious wearing part. The maximum impact is on this part which could be the first failure area. We design to use unequal thickness on the back part. From both ends to the middle gradually become thicker.
According to the condition that the inside of the bending pipe has less wear, the wear resistant layer with 6mm thickness is adopted in the lower half part of the bending pipe. and that thickness on the back part is 12-30mm.

1. Concrete pump elbow for boom pump, trailer pump, stationary pump, truck mounted pump
Twin wall elbow ’s service life and working pressure are better than the casting. Besides, We can supply 90D, 45D, 30D, 25D, 20D, 15D, 10D. And it can be used for PM, Schwing, Cifa, Sany, Zoomlion ect.
2. Wear resisdtant. the elbow lifetime: 60000-80000 cube.
3. The surface treatment: baking paint. two time bend .our have more beautiful product.
4. The size compete, we have all the size concrete pump casting elbow. used for boom pump Putzmeister,Sany, Schwing , and so on.
