I-P235TR1 impahla yepayipi lensimbi ukwakheka kwayo kwamakhemikhali ngokuvamile kuhambisana ne-EN 10216-1 standard.isitshalo samakhemikhali, imikhumbi, ukwakhiwa kwamapayipi kanye nokujwayelekileizinjongo zobunjiniyela bemishini.

Ngokwezinga, ukwakheka kwamakhemikhali e-P235TR1 kufaka phakathi i-carbon (C) okuqukethwe okufika ku-0.16%, i-silicon (Si) okuqukethwe kufika ku-0.35%, okuqukethwe kwe-manganese (Mn) phakathi kuka-0.30-1.20%, i-phosphorus (P) nesibabule (S ). ) okuqukethwe kuphezulu okungu-0.025% ngokulandelanayo. Ngaphezu kwalokho, ngokuya ngezidingo ezijwayelekile, ukwakheka kwe-P235TR1 kungase futhi kuqukathe amanani omkhondo wezinto ezifana ne-chromium (Cr), ithusi (Cu), i-nickel (Ni) ne-niobium (Nb). Ukulawulwa kwalokhu kuhlanganiswa kwamakhemikhali kungaqinisekisa ukuthi amapayipi ensimbi e-P235TR1 anezakhiwo ezifanele zemishini nokumelana nokugqwala, okuwenza afanelekele ukusetshenziswa kwezinye izinhlelo zokusebenza zezimboni ezithile.

Ngokombono wokwakheka kwamakhemikhali, okuqukethwe kwekhabhoni ephansi kwe-P235TR1 kusiza ukuthuthukisa ukushisela nokucutshungulwa kwayo, futhi okuqukethwe kwayo kwe-silicon kanye ne-manganese kusiza ukuthuthukisa amandla ayo kanye nokumelana nokugqwala. Ukwengeza, okuqukethwe kwe-phosphorus nesulfure kudinga ukulawulwa emazingeni aphansi ukuze kuqinisekiswe ukuhlanzeka kwezinto ezibonakalayo kanye nokucutshungulwa. Ukuba khona kwezakhi zokulandelela ezifana ne-chromium, ithusi, i-nickel ne-niobium kungase kube nomthelela ezintweni ezithile zamapayipi ensimbi, njengokumelana nokushisa noma ukumelana nokugqwala.

Ngaphandle kokwakheka kwamakhemikhali, inqubo yokukhiqiza, izindlela zokwelashwa kokushisa nezinye izinkomba zokusebenza ngokomzimba zepayipi lensimbi le-P235TR1 nazo ziyizici ezibalulekile ezithinta ukusebenza kwayo kokugcina. Ngokuvamile, ukwakheka kwamakhemikhali kwepayipi lensimbi le-P235TR1 kungenye yezinto ezibalulekile zokuqinisekisa ukuthi ihlangabezana nezidingo zezindinganiso ezifanele futhi ingahlangabezana nezinhloso ezithile zobunjiniyela.
