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. Technical Assistance

  • Our Technician and experts can provide technical assistance at the request of customers
  • Test vessel with standard environment chamber is machined from clear, durable acrylic to permit instant visual observation of the specimen at all times. Glass with acrylic vessels is also available at option of user. O-Ring Seals are provided to prevent any leakages from test vessel. Individual Test Vessels are tested with hydro test of air before dispatch
  • SSC Proof Rings are very economical and high durability. We have selected best material quality and maintain calibration certificate of SSC Proof Rings

Gap-A-Lets + Socket Weld Contraction Ring

Gap-A-Lets + Socket Weld Contraction Ring
Gap-A-Let® is a split ring that is engineered and designed to give you a pre-measured 1/16" minimum gap for socket welds. Made from a certified stainless steel, Gap-A-Let® resists corrosion from chemicals, radioactive materials, and water. Gap-A-Let®'s spring tension makes it fit tightly into all standard sized fittings from 1" to 4". (Non-standard sizes are available upon request.) Once inserted into the fitting, the Gap-A-Let® ring becomes a permanent part of the joint. It will not rattle or vibrate even under extreme pressure.

Where Is It Used?

Designed for use on any socket weld application, Gap-A-Let® rings are suitable for Power Piping (Nuclear, Conventional), Industrial Hydraulics, Welded Railroad Air Brake Piping, Petrochemical Plants, Fertilizer Plants, Shipbuilding,  and the list goes on and on.

Standard Gap-A-Let® Rings -- 1/4" NPS - 2" NPS

Heavy Duty Gap-A-Let® Rings -- 2 1/2" NPS - 4" NPS
