SOP with notches flat – the standard sample of the enterprise

Enterprise standard samples (SOP) with flat corner reflectors (notches) are used to adjust the sweep duration and sensitivity of flaw detectors when testing sheet and pipe products of large diameters with inclined combined transducers.

SOP flat are made with one or two notches. The geometric dimensions of the SOPs themselves (thickness of flat samples) and notches are determined by the regulatory and technical documentation for the control.

All standard samples are supplied with calibration certificates.

Samples are made of steels of the following grades:

• st.20,
• st.3,
• st. 09G2S.

It is possible to manufacture SOPs from the customer’s materials, similar to the materials of controlled products, and to manufacture up to 4 notches on a sample, according to 4 documents.

All samples are made in accordance with GOST 14782-86 “Non-destructive testing. Welded joints. Ultrasonic methods” according to the following regulatory documents:

• RD 34.17.302-97 (OP-501 TsD-97) “Steam and hot water boilers. Steam and hot water pipelines, vessels. Welded joints. Quality control. Ultrasonic testing. Basic provisions”;
• RD ROSEK-001-96 “Loading machines. Metal structures. Ultrasonic control. Basic provisions”;
