I-P235TR1 iyisitabane samapayipi ensimbi esihlanganisiwe sokwakheka kwalo okuvame ukuhambisana ne-EN 10216-1 standard.isitshalo samakhemikhali, imikhumbi, ukwakhiwa kwePipework kanye nokujwayelekileIzinjongo Zobunjiniyela Bemishini.

Ngokusho kweZinga, Ukwakheka kwamakhemikhali kwe-P235TR1 kufaka okuqukethwe kwe-carbon (c) kufika ku-0.16 (Si) okuqukethwe okufika ku-0.30-1.20%, i-phosphorus (p) kanye ne-sulfur (s). ) Okuqukethwe kuphezulu ngo-0,025% ngokulandelana. Ngaphezu kwalokho, ngokuya ngezidingo ezijwayelekile, ukwakheka kwe-P235TR1 kungaqukatha amanani entengo yezinto ezifana ne-chromium (CR), i-Copper (CU), i-nickel (NI) ne-niobium (NB). Ukulawulwa kwalezi zingoma zamakhemikhali kungaqinisekisa ukuthi amapayipi ensimbi e-P235TR1 anezakhiwo ezifanele zemishini nokumelana nokugqwala, okwenza balungele ukusetshenziswa kwezinye izinhlelo zezimboni.

Ngokombono wokwakheka kwamakhemikhali, okuqukethwe okuphansi kwekhabhoni okuphansi kusiza ukuthuthukisa ukusheshiswa kwayo nokusetshenzelwa kwayo, futhi okuqukethwe kwalo sase-silicon kanye ne-manganese kusiza ukuthuthukisa amandla ayo nokuphikiswa kokugqwala. Ngaphezu kwalokho, okuqukethwe kwe-phosphorus nokuqukethwe kwesibabule kudinga ukulawulwa emazingeni aphansi ukuqinisekisa ubumsulwa bezinto ezibonakalayo kanye nokusebenza. Ukuba khona kwama-trace izinto njenge-chromium, ithusi, i-nickel ne-niobium kungenzeka kube nomthelela ezindaweni ezithile zamapayipi ensimbi, njengokuphikiswa kokushisa noma ukumelana nokushisa.

Ngaphezu kokwakheka kwamakhemikhali, inqubo yokukhiqiza, izindlela zokwelashwa zokushisa nezinye izinkomba zokusebenza kwensimbi ye-P235TR1 zensimbi nazo zibalulekile ezintweni ezithinta ukusebenza kwayo kokugcina. Ngokuvamile, ukwakheka kwamakhemikhali kwe-P235TR1 I-Pipe yensimbi kungenye yezinto ezibalulekile ukuqinisekisa ukuthi ihlangabezana nezidingo zamazinga afanele futhi ingahlangabezana nezinhloso zobunjiniyela ezithile.
