ST52 Boom Pipe
Putzmeister pipes meet or exceed all specifications of concrete pipe manufacturers for wall thickness, inner and outer diameter tolerance, weight restrictions, working pressure, and safety. Putzmeister’s new range of high-wear pipe is ideal for mining, tunneling, mills, foundries, and power plants.
It includes non-hardened ST52 mild steel, single-layer induction hardened, and twin-layer hardened pipes, elbows, tees, wyes, and reducers. It is best used for in-plant piping, tailing and backfill lines, waste disposal, and slurry transport.
The new pipe’s diameter ranges from 3 inches to 10 inches, with larger diameters, up to 24 inches, available upon request. Wall thickness ranges from 0.16 inches up to 0.50 inches.
Single-wall pipe is hardened to 54 HRC, resulting in a service life which is two to three times longer than ST52. the twin-layer pipe is hardened to 67 HRC.providing an even longer life of five to 10 times that of ST52.
Depending on diameter and application, the coupling connections can be fitted with smooth or centered weld ends. Centered connections are able to withstand pressures up to 200 bar (2900 psi). Drop forged snap couplings secured with splint pins or screw couplings, as well as flange connections ranging from standard, raised or flat face, slip-on or butt-welded, connect two conveying components.
Offering a wide variety of pipe quality, sizes, and ends, Putzmeister’s new industrial pipe product range allows users to customize their own unique system to meet almost any job site demand.
