The control group according to GOST R 33259
On the flange marking in accordance with GOST 33259 there are Roman numerals I, II, III, IV, V. These figures indicate to which control group the flange belongs. Below is a table with a detailed description.
| Control group | Batching conditions | Type and scope of testing | Delivery characteristics | Applicability |
|---|---|---|---|---|
| I | Billets of one steel grade | Chemical analysis - each melt | Chemical composition | For flanges PN ≤ 2,5 DN ≤ 300 for liquid working media not related to hazardous substances |
| II | Billets of the same steel grade, jointly heat treated | Chemical analysis - each melt. Hardness measurement - 5% batch, but not less than 5 pcs. IWC on request |
Chemical composition. Hardness |
For flanges PN ≤ 6 all DN and for flanges PN ≤ 16 DN ≤ 300 for non-hazardous media |
| III | Billets of the same steel grade, heat-treated in the same mode | Chemical analysis - each melt. Hardness measurement - each billet. Unbrakable control - at the request of the customer. IWC on request |
Chemical composition. Hardness |
For flanges PN ≤ 25 all DNs for non-hazardous media. For flanges PN ≤ 6 DN ≤ 150 for liquid working media related to hazardous substances |
| IV | Chemical analysis - each melt. Hardness measurement - each billet. Mechanical properties - 1% of each set, but not less than 2 pcs. Non-destructive testing - each piece. IWC on request |
Chemical composition. Hardness. Mechanical properties (yield strength, relative narrowing, impact strength). Resistance to ICC |
For flanges PN ≤ 160 all DN for all media | |
| V | Individually each blank | Chemical analysis - each melt. Hardness measurement - each billet. Mechanical properties - each billet. Non-destructive testing - each piece. IWC on request |
For flanges PN> 160 all DN for all media |
