ESSER ELBOWS
Since the impact elbow is exposed to the high velocity and turbulence of the concrete, it is critical to have a concrete elbow that is as durable as your pipe. Esser elbows feature the same twin layers as our long-lasting pipes so they can withstand the high-impact and abrasive wear stressing that takes place in a concrete elbow.
Esser 900 Elbow
The lightweight Esser 90º elbow is designed specifically for pipe systems fitted on large truck-mounted concrete boom pumps. This concrete elbow features a reduced weight to protect the boom design and improve stability. This Esser 900 lightweight 90º elbow serves as the ultimate solution for performance and wear life at a reduced weight.
This concrete elbow has a mild steel outer pipe and a solid inner pipe of the unique steam-hardened Esser 900 twin-cast material. It is completed with two Esser 900 twin-cast Big Mouth flanges. This Esser elbow also has a hardness of 67 HRc throughout the entire inner cast pipe.
Esser 660 Elbow
The Esser 660 concrete elbow is a twin-layer impact elbow with an inner pipe hardness of up to 63 HRc. This Esser elbow is heat treated throughout the entire length and thickness of the inner pipe, with a depth of 0.28 inches (7mm). This Esser impact elbow is completed with two patented Esser 660 flanges.
