Description

API RP 2X Reference Standards LEVEL C BLOCK (INCH VERSION) MONAL 800

The reference block for a Level C examination should contain planar reflectors compatible with the smallest rejectable flaw. One reference block containing a square (buttress) notch and one each with V-notches for 45–degree, 60–degree, and 70–degree orientations should be available for establishing scanning sensitivity for root reflectors. In addition to notches for root reflectors, the side of a 1/16-inch drilled hole provides an excellent reference for internal reflectors. The response from known size implant reflectors in the operator’s test coupons should be compared with the reflections from the reference blocks to assure that the sensitivity will result in detection of the smallest flaw of interest. Level "C" examination recommended practice 2X (RP 2X). Ultrasonic examination of offshore structural fabrication and guidelines for qualifications of ultrasonic technicians.

DIMENSION : Set of 4 blocks required, In accordance with API RP 2X.

9" (L) X 2" (W) X 1" (T) 

Note : “T” based on the material and equipment that will be used.

Block Contains : One Side Drill Hole of Dia Ø1/16" Deep 1½"

One block containing a square notch and one each with V-notches for 45°, 60° and 70° orientations, for establishing scanning sensitivity for root reflectors. Simulated references for reject able flaws established by the Operator's UT specialist, should be added to this block for the calibration of internal reflectors.
