Amapayipi ensimbi angenamthungo adlala indima ebalulekile ezinhlelweni zezimboni, futhiEn 10210futhi en 10216 yizincazelo ezimbili ezijwayelekile emazingeni e-Europe, kubhekiswe kumapayipi ensimbi angenamthungo ukuze asetshenziswe ngokulandelana.

En 10210 Standard
Impahla nokwakheka:
Le khasiEn 10210Okujwayelekile kusebenza kumapayipi ensimbi avuselelayo anezinhlaka zezakhiwo. Izinto ezijwayelekile zifaka i-S235JRH, S275J0H,S355J2H, njll. Izingxenye eziphambili ze-alloy yalezi zinto zokwakha zifaka i-carbon (c), i-manganese (mn), i-silicon (SI), njll. Izakhi ezithile zihluka ngokuya ngamabanga ahlukene. Isibonelo, okuqukethwe kwekhabhoni ye-S355jj2H akudluli ku-0,22%, futhi okuqukethwe malingani kumayelana ne-1,6%.

Ukuhlolwa kanye nemikhiqizo eqediwe:
En 10210Amapayipi ensimbi adinga ukubhekana nokuhlolwa kwempahla okuqinile kwemishini, kufaka phakathi namandla ashubile, amandla okuthela nokuhlolwa okuphezulu. Ngaphezu kwalokho, kudingeka izivivinyo zobunzima bokuqina ngokuqinisekisa ukusebenza ezindaweni eziphansi zokushisa. Umkhiqizo osuqediwe kufanele uhlangabezane nokubekezelelana okubucayi kanye nezidingo ezisezingeni eliphakeme ezichazwe kuzinga, futhi ingaphezulu livame ukugcwaliseka.

En 10216 standard
Impahla nokwakheka:
Isilinganiso se-EN 10216 sisebenza kumapayipi ensimbi angenamthungo wokusebenzisa ingcindezi. Izinto ezijwayelekile zifaka i-P235GH, P265GH, 16Mo3, njll. Lezi zinto zokwakha ziqukethe izinto ezahlukile zokubopha. Isibonelo, i-P235GH inokuqukethwe kwekhabhoni kungabi ngaphezu kwe-0.16% futhi iqukethe i-manganese ne-silicon; I-16Mo3 iqukethe i-molybdenum (Mo) kanye ne-manganese, futhi inokumelana nokushisa okuphezulu.

Ukuhlolwa kanye nemikhiqizo eqediwe:
I-EN 10216 Amapayipi ensimbi adinga ukuphumelela uchungechunge lwezinqubo zokuhlola eziqinile, okubandakanya ukuhlaziywa kokwakheka kwamakhemikhali, ukuhlolwa kwempahla okwenziwe ngomshini nokuhlolwa okungelonakalisayo (njengokuhlolwa kwe-ultrasonic kanye nokuhlolwa kwe-x-ray). Ipayipi lensimbi eliqediwe kufanele lihlangabezane nezidingo zokunemba okunobunzima kanye nokubekezelelana kodonga, futhi kuvame ukudinga ukuhlolwa kwe-hydrostatic ukuqinisekisa ukuthembeka kwayo ezindaweni eziphakeme kakhulu.

Ukubeka kafushane
Le khasiEn 10210futhi amazinga we-10216 amapayipi ensimbi angenamthungo angemapayipi ensimbi ahlelekile nengcindezelo ngokulandelana, emboza izidingo ezahlukahlukene zezinto ezibonakalayo nezakhi. Ngokuhlola okuqinile kokuhlola kanye nezinqubo zokuhlola, izakhiwo zemishini kanye nokwethenjwa kwamapayipi ensimbi kuyaqinisekiswa. Lezi zindinganiso zinikeza isisekelo esithembekile sokukhethwa kwamapayipi ensimbi ezihlolweni ezahlukahlukene zezimboni, ukuqinisekisa ukuphepha nokuqina kwephrojekthi.
