Fusing at higher interfacial pressures
Discussion continues as to whether the best way to fuse polyethylene (PE) pipe is at an interfacial pressure of 0.15 MPa (21.75 psi) or 0.517MPa (75 psi). Both procedures are widely used and produce good outcomes when destructively tested as well as surviving the test of time. A paper by Ted Striplin of McElroy Manufacturing in the USA sets out to provide some preliminary examples for the benefits of fusing at higher interfacial pressures.
