Advantages of Concrete Pumping Elbow:
1.Concrete pump elbow for boom pump, trailer pump, stationary pump, truck mounted pump
2. Twin wall elbow ’s service life and working pressure are better than the casting. Besides, The Twin wall elbow’s structure ensures high abrasion resistance and toughness.
3. Chromium alloy iron casting enables the liner highly wear proof and reduce pressure
4. Seamless welding enables the the outer layer hard to explode
5. Light weight improves vehicle efficiency, highly reduces labor and cost and the time for replacement
6. Designed structure, material and process realize its 3-5 times service life of common products
7. to extend the service life of other pipe fitting
8. Easy to use and handle
