Expert Commentary
Standard Method for Apparent Hoop Tensile Strength of Plastic or Reinforced Plastic Pipe (Nol-Ring Method). This uses a ring specimen cut from a pipe. The ring is loaded using a Split-Disk fixture. The engineering challenge is the friction between the disk and the ring, which can skew the tensile data. MTO’s split-disk fixtures are precision-ground and lubricated to minimize friction. This test is vital for pressurized water and gas pipes, providing the Hoop Stress capacity needed for long-term safety factor calculations.
