Rolling Torque

This paper advocates correlating rolling torque or hydraulic expanding pressure with shear load strength instead of percent wall reduction as the criterion of expanding adequacy for thin-walled tubes. It compares magnitudes of measurements required to estimate wall reduction with cumulative hole-drilling and tube-manufacturing tolerances and graphically illustrates data scatter increase with ratio of tube diameter to wall thickness. As background it discusses expanding theory. It covers hydraulic, roller and hybrid expanding. It describes appropriate annular groove widths for hydraulic and hybrid expanding and concludes with comments on tube rolling procedure specifications and recommendations for two-stage and hybrid expanding.

We are studying the crystallization and annealing behavior of high performance polymers, like poly(p-pheny1ene sulfide) PPS, and poly-(etheretherketone), PEEK. Our purpose is to determine whether PPS, which is similar in many ways to PEEK, undergoes reorganization during annealing. In an effort to address the issue of reorganization, we are studying solution grown single crystals of PPS as model materials.Observation of solution grown PPS crystals has been reported. Even from dilute solution, embrionic spherulites and aggregates were formed. We observe that these morphologies result when solutions containing uncrystallized polymer are cooled. To obtain samples of uniform single crystals, we have used two-stage self seeding and solution replacement techniques.
