Amapayipi ensimbi angenasici adlala indima ebalulekile ekusetshenzisweni kwezimboni, futhiI-EN 10210kanye ne-EN 10216 yizicaciso ezimbili ezijwayelekile ezilinganisweni zase-Europe, eziqondise amapayipi ensimbi angenamthungo ekusetshenzisweni kwesakhiwo nokucindezela ngokulandelana.

I-EN 10210 Standard
Impahla nokwakheka:
II-EN 10210okujwayelekile kusebenza kumapayipi ensimbi angenamthungo awakhelwe ngokushisayo ezakhiwo. Izinto ezijwayelekile zifaka i-S235JRH, S275J0H,I-S355J2H, njll. Izingxenye eziyinhloko ze-alloy zalezi zinto zifaka i-carbon (C), i-manganese (Mn), i-silicon (Si), njll. Ukwakheka okuqondile kuyahlukahluka kuye ngamamaki ahlukene. Isibonelo, okuqukethwe kwekhabhoni ye-S355J2H akudluli u-0.22%, futhi okuqukethwe kwe-manganese cishe ku-1.6%.

Ukuhlola kanye nemikhiqizo eqediwe:
I-EN 10210amapayipi ensimbi adinga ukuhlolwa okuqinile kwezakhiwo, okuhlanganisa amandla aqinile, amandla esivuno kanye nokuhlolwa kobude. Ukwengeza, ukuhlolwa kokuqina komthelela kuyadingeka ukuze kuqinisekiswe ukusebenza ezindaweni zokushisa eziphansi. Umkhiqizo oqediwe kufanele uhlangabezane nokubekezelelana kwe-dimensional kanye nezidingo zekhwalithi yangaphezulu ezicaciswe ezingeni, futhi indawo engaphezulu ivamise ukugqwala.

I-EN 10216 Standard
Impahla nokwakheka:
Izinga le-EN 10216 lisebenza kumapayipi ensimbi angenamthungo ukuze asetshenziswe ngomfutho. Izinto ezijwayelekile zifaka i-P235GH, i-P265GH, i-16Mo3, njll. Lezi zinto ziqukethe izakhi ezihlukene ze-alloying. Isibonelo, i-P235GH inokuqukethwe kwekhabhoni okungengaphezu kuka-0.16% futhi iqukethe i-manganese ne-silicon; I-16Mo3 iqukethe i-molybdenum (Mo) ne-manganese, futhi inokumelana nokushisa okuphezulu.

Ukuhlola kanye nemikhiqizo eqediwe:
I-EN 10216 amapayipi ensimbi adinga ukudlula uchungechunge lwezinqubo zokuhlola eziqinile, okuhlanganisa ukuhlaziya ukwakheka kwamakhemikhali, ukuhlola impahla eyimishini kanye nokuhlola okungabhubhisi (njengokuhlolwa kwe-ultrasonic nokuhlolwa kwe-X-ray). Ipayipi lensimbi eliqediwe kufanele lihlangabezane nezidingo zokunemba kwe-dimensional kanye nokubekezelelana kokuqina kodonga, futhi ngokuvamile kudinga ukuhlolwa kwe-hydrostatic ukuze kuqinisekiswe ukwethembeka kwayo ezindaweni ezinomfutho ophezulu.

Isifinyezo
II-EN 10210kanye namazinga we-EN 10216 wamapayipi ensimbi angenamthungo ngawesakhiwo namapayipi ensimbi yokucindezela ngokulandelana, amboze izinto ezihlukene kanye nezidingo zokwakheka. Ngokuhlola okuqinile kanye nezinqubo zokuhlola, izakhiwo zemishini nokuthembeka kwamapayipi ensimbi kuqinisekiswa. Lezi zindinganiso zinikeza isisekelo esithembekile sokukhethwa kwamapayipi ensimbi emisebenzini ehlukene yezimboni, ukuqinisekisa ukuphepha nokuzinza kwephrojekthi.
