 | Extended Range Variable Wall® Piping Calibration Blocks for Longseam Inspection This set of two blocks has been specially designed for situations
where ultrasonic examination takes place circumferentially or
“around the curve” for applications such as inspection of longseam
welds in piping and vessels. Jointly designed by PH Tool and
Holloway NDT, the blocks feature side-drilled hole reflectors
positioned within novel compound-curves, each with multiple
thickness steps. The unique design results in a light and compact
form factor, with the largest block weighing just over 15 lbs and
spanning just 16 ¾”.
Coverage is provided for nominal pipe sizes from 6” to 10” in the
small block and 12” to a whopping 56” in the large block. The
compound OD curves and multiple wall thicknesses actually exceed
ASME requirements, providing exceptional signal response and
measurement accuracy. Properly managing beam divergence off the
ID and stabilizing beam skew due to probe rocking is essential to
maintaining a consistent calibration when inspecting lengthwise on
curved surfaces. Ultrasonic Testing |  | Capabilities / Services Offered PH Tool manufactures special NDT test blocks and reference
standards to customer specifications in our fully-equipped CNC/EDM
manufacturing facility. We are a full-capability shop, from start
to finish, so lead times are always reasonable. Our broad range of
machining capabilities and expertise enables us to respond quickly
to emergency or rush delivery requirements. If you need one block
or 100, we can make it. We offer the complete package; including
CAD/CAM, pre-machining, ultrasonic inspection of raw material, CNC
milling and EDM, drilling, turning, boring, grinding, dimensional
inspection, welding, cladding, and more. NDT Wide |  | NDT Standards for Bar & Tube Inspection Systems and Metals Manufacturers PH Tool is proud to serve many customers in the field of primary
metals manufacturing. This includes iron and steel producers,
aluminum mills, and other producers of nonferrous metals. When
metals manufacturers adopted sophisticated, in-line phased array
ultrasonic and eddy current technology to inspect their product,
they turned to PH Tool to manufacture their complex calibration
standards for bar and tube inspection. Ultrasonic Testing |  | ERVD™ Thickness Calibration Block The second addition to the Extended Range Variables (ERV™) product
line, this Extended Range Variable Diameter (ERVD™) Thickness
Calibration Block was jointly designed by PH Tool and Holloway NDT,
intended for use as a versatile curved step block for thickness
testing of pipe. Available in both Inch and Metric. Ultrasonic Testing |  | ASME-Compliant Extended Range Variable Wall (ERVW)® Piping Calibration Blocks PH Tool and Holloway NDT have jointly designed and produced a set
of three Extended Range Variable Wall (ERVW)® Piping
Calibration Blocks. Created for calibration in the
axial direction for examination of circumferential butt welds,
these blocks come in three sizes: small (3” to 5”), medium (6”
to 10”) and large (12” to 20”). These blocks range from 3 to
20 pounds and 7 to 16 inches, making them lightweight and
portable. Product Video Ultrasonic Testing |
