DN125 Wear resistant Concrete Pump Boom Elbow

 

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 boom elbows.

 

We are able to provide all different types of ceramic lined concrete pump boom elbows and special installations.

 

We can also make the standard and nonstandard ceramic lined concrete pump boom elbows according to customers’requirement.

 

The advantages of alumina ceramic lined concrete boom pump elbow

 

1. The weight is lighter than normal elbow.

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 elbows.
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.

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.
