Jointly designed by PH Tool and Holloway NDT, the fully ASME-compliant ERVW® Line of Calibration Blocks is an innovative development that has dramatically improved inspection efficiency. ERVW Blocks are carefully designed to make use of tolerance and allowances in ASME code to cover the maximum number of inspection sizes with just a few select blocks. Adding these blocks your kit will save a ton of weight and space vs. hauling dozens of individual cal blocks. The best part? – you’ll never find yourself without that “one missing size” that you need for your next inspection, saving you from scrambling to have a new block made.
ERVW Blocks sets are available for pipe inspection in the axial direction, with an option for either side drilled holes or notches as the reflector type, as well as a separate set for pipe inspection in the circumferential direction. Additionally, the new ERVD™ thickness calibration block is useful for thickness testing of multiple curved surfaces.

Jointly designed by PH Tool and Holloway NDT, this block provides six flat calibration blocks in one unique design for ASME piping inspections on diameters greater than 20 inches.
The section thicknesses are .250”, 0.375”, 0.500”, 0.750”, 1.0” and 1.5”, providing coverage based on ASME Section V Art. 4 tolerances for piping from 0.200” all the way to 2”.
The block features side-drilled hole (SDH) reflectors which are permitted as per ASME and provide a much more consistent reference target over a wide range of angles as compared to notches. The SDHs also function as ASME-compliant reflectors for non-piping applications (T-434.2.1.) The block is suitable for conventional as well as phased array ultrasonic calibrations. Each section is conveniently engraved to indicate the range of pipe thicknesses covered. The weight is just 13 lbs, only slightly heavier than a standard IIW block.
