Amapayipi ensimbi angenamthungo adlala indima ebalulekile ekusetshenzisweni kwezimboni, futhiI-EN 10210kanye ne-EN 10216 yizincazelo ezimbili ezivamile ezindinganisweni zaseYurophu, ezihlose amapayipi ensimbi angenamthungo okusetshenziswa kwesakhiwo kanye nokusetshenziswa kwengcindezi ngokulandelana.

I-EN 10210 Standard
Izinto zokwakha kanye nokwakheka kwazo:
II-EN 10210indinganiso isebenza kumapayipi ensimbi angenamthungo akhiwe ngokushisa ezakhiweni. Izinto ezivamile zifaka phakathi i-S235JRH, i-S275J0H,S355J2H, njll. Izingxenye eziyinhloko ze-alloy zalezi zinto zifaka phakathi i-carbon (C), i-manganese (Mn), i-silicon (Si), njll. Ukwakheka okuthile kuyahlukahluka ngokuya ngamamaki ahlukene. Isibonelo, okuqukethwe kwe-carbon kwe-S355J2H akudluli ku-0.22%, kanti okuqukethwe kwe-manganese cishe kungama-1.6%.

Ukuhlolwa kanye nemikhiqizo eqediwe:
I-EN 10210Amapayipi ensimbi adinga ukuhlolwa okuqinile kwezakhiwo zemishini, okuhlanganisa amandla okunamathela, amandla okukhiqiza kanye nokuhlolwa kobude. Ngaphezu kwalokho, kudingeka ukuhlolwa kokuqina komthelela ukuqinisekisa ukusebenza ezindaweni eziphansi zokushisa. Umkhiqizo oqediwe kumele uhlangabezane nokubekezelelana kobukhulu kanye nezidingo zekhwalithi yobuso ezichazwe ku-standard, futhi ubuso buvame ukungagqwali.

I-EN 10216 ejwayelekile
Izinto zokwakha kanye nokwakheka kwazo:
Izinga le-EN 10216 lisebenza kumapayipi ensimbi angenamthungo okusetshenziswa ngomfutho. Izinto ezivamile zifaka phakathi i-P235GH, i-P265GH, i-16Mo3, njll. Lezi zinto ziqukethe izakhi ezahlukene zokuxuba. Isibonelo, i-P235GH inokuqukethwe kwekhabhoni okungaphezu kuka-0.16% futhi iqukethe i-manganese ne-silicon; i-16Mo3 iqukethe i-molybdenum (Mo) ne-manganese, futhi inokumelana nokushisa okuphezulu.

Ukuhlolwa kanye nemikhiqizo eqediwe:
Amapayipi ensimbi e-EN 10216 adinga ukudlula uchungechunge lwezinqubo zokuhlola eziqinile, okuhlanganisa ukuhlaziywa kokwakheka kwamakhemikhali, ukuhlolwa kwempahla yemishini kanye nokuhlolwa okungonakalisi (njengokuhlolwa kwe-ultrasonic kanye nokuhlolwa kwe-X-ray). Ipayipi lensimbi eliqediwe kumele lihlangabezane nezidingo zokunemba kobukhulu kanye nokubekezelela ukujiya kodonga, futhi ngokuvamile lidinga ukuhlolwa kwe-hydrostatic ukuqinisekisa ukuthembeka kwalo ezindaweni ezinomfutho ophezulu.

Isifinyezo
II-EN 10210kanye nezindinganiso ze-EN 10216 zamapayipi ensimbi angenamthungo zenzelwe amapayipi ensimbi esakhiwo kanye nengcindezi ngokulandelana, ehlanganisa izidingo zezinto zokwakha kanye nokwakheka okuhlukile. Ngokusebenzisa izinqubo zokuhlola eziqinile kanye nokuhlola, izakhiwo zemishini kanye nokuthembeka kwamapayipi ensimbi kuyaqinisekiswa. Lezi zindinganiso zinikeza isisekelo esithembekile sokukhethwa kwamapayipi ensimbi ezisetshenziswayo ezahlukene zezimboni, okuqinisekisa ukuphepha nokuzinza kwephrojekthi.
