Permissible Deviations nyob rau hauv Nyhav thiab Dimensions
1. Sab nraud txoj kab uas hla - ± 0.5% ntawm qhov ntsuas sab nraud raws li qhov ntsuas qhov ntsuas.
2. Roundness - Qhov txawv ntawm qhov siab tshaj plaws sab nraud txoj kab uas hla thiab qhov tsawg kawg nkaus sab nraud txoj kab uas hla.
3. Kev sib tw - Siv tus kav 10-ko taw (3-meter) nrog ob qho kawg ntawm kev sib cuag nrog cov yeeb nkab, qhov kam rau siab yog 1/8 nti (3 hli).
4. Thickness - Qhov tsawg kawg nkaus phab ntsa thickness ntawm cov yeeb nkab ntawm txhua qhov chaw yuav tsum tsis pub tsawg tshaj 0.01 nti (0.3 hli) ntawm lub npe nominal thickness.
5. Qhov ntev ntawm qhov tsis ua tiav yuav tsum nyob rau hauv -0, +1/2 nti (-0, +13 mm) ntawm qhov ntev. Qhov ntev ntawm cov txheej txheem tiav yuav raug txiav txim los ntawm kev pom zoo ntawm cov chaw tsim khoom thiab cov neeg yuav khoom.
ASTM A671 Mechanical Properties Tests rau Ncaj Seam Submerged Arc Welded Carbon Steel Yeeb Nkab:
Tensile Test - Lub transverse tensile zog ntawm cov welded sib koom yuav tsum tau raws li qhov tsawg kawg nkaus yuav tsum tau ntawm lub phaj qhov kawg tensile zog.
Transversely Guided Weld Bend Test-Kev ntsuas khoov tau txais yog tias tsis muaj cov kab nrib pleb lossis lwm yam tsis xws luag tshaj 1/8 nti (3 hli) nyob rau hauv ib qho kev taw qhia ntawm cov hlau weld lossis nruab nrab ntawm cov vuam thiab cov niam txiv hlau tom qab khoov.
Radiographic Examination-Txhua qhov ntev ntawm Qib X1 thiab X2 welds yuav tsum tau kuaj xyuas hluav taws xob raws li qhov yuav tsum tau muaj ntawm Tshooj UW-51 ntawm Tshooj 7 ntawm ASME Boiler thiab Pressure Vessel Code.
