SSC Proof Rings


SSC Proof Rings

Caltech Engineering Services is pleased to introduce latest designed, user friendly, economical SSC Proof Rings manufactured to test and accurately determine the sulphide stress cracking susceptibility of metals in H2S service. Proof Rings meet NACE Standard TM-0177 and Material Standard requirements as per TM0175.Each SSC Proof Ring is provided with ready conversion chart that can accurately determine specimen load. It also provides sustained specimen load under a stress state of uniaxial tension. SSC Proof Rings are supplied with digital dial indicator providing a check for deflection. SSC Proof Rings are fabricated from precision-machined steel and suitable to test full size specimens of 0.252’ (6.40mm). Tensile load on the SSC Proof Ring can be achieved quickly and easily adjusted using a workshop wrench on the tension-adjusting screw and lock nut. A thrust bearing distributes the load and prevents seizure. SSC Proof Rings are provided with quick changeover accessories to effectively meet your needs.
