Putzmeister Esser 900 4.6" (117mm) Big Mouth XL Boom Pipe

Putzmeister’s premier boom pipe offering, Esser 900 pipe has the longest service life on the market and is ideal for high-volume pumping under extreme wear conditions. This ultra wear-resistant pipe is made of a static outer pipe with an inner pipe with heat-treated hardness up to 67 HRc. It is fitted with two patented twin-cast Big Mouth flanges to prevent the radical transfer of destructive wear from the elbow to the straight pipe. A unique welding process results in no heat-affected areas of the pipeline.
