Amapuleti ensimbi angagugi aqukethe ipuleti lensimbi elingakhabhoni ephansi kanye nesendlalelo esingagugi se-alloy, kanti isendlalelo esingagugi se-alloy ngokuvamile siqukethe u-1/3 kuya ku-1/2 wobukhulu obuphelele. Ngesikhathi sokusebenza, izinto eziyisisekelo zinikeza izakhiwo eziphelele ezifana namandla, ukuqina, kanye nokuguquguquka kokumelana namandla angaphandle, kuyilapho isendlalelo esingagugi se-alloy sinikeza ukumelana nokugugi okulungiselelwe izimo ezithile zokusebenza.
Isendlalelo esingagugi se-alloy kanye nezinto eziyisisekelo ziboshelwe ngensimbi. Kusetshenziswa imishini ekhethekile kanye nenqubo yokushisela ezenzakalelayo, ucingo lwe-alloy oluqinile, oluzivikelayo lushintshwa ngokulinganayo ezintweni eziyisisekelo. Isendlalelo esihlanganisiwe singaba isendlalelo esisodwa, ezimbili, noma eziningi. Ngenxa yokushintshashintsha kwezilinganiso zokuncipha kwe-alloy, imifantu efanayo evuvukalayo iyavela ngesikhathi senqubo yokushisela, uphawu lwamapuleti ensimbi angagugi.
Ingqimba engagugi ye-alloy yakhiwe ngokuyinhloko nge-chromium alloy, kanye nezinye izinto ezixubayo njenge-manganese, i-molybdenum, i-niobium, kanye ne-nickel. Ama-carbide esakhiweni se-metallographic ane-fibrous, kanti imicu iqondiswe ngqo ebusweni. Ubulukhuni be-carbide bungafinyelela ngaphezu kwe-HV 1700-2000, kanti ubulukhuni bomphezulu bungafinyelela ku-HRC 58-62. Ama-carbide e-alloy azinzile kakhulu emazingeni okushisa aphezulu, agcina ubulukhuni obuphezulu kanye nokumelana okuhle kakhulu kwe-oxidation, okuvumela ukusebenza okugcwele ngaphakathi kwamazinga okushisa afinyelela ku-500°C.
Ingqimba engagugi ingavela emaphethini amancane (2.5-3.5mm) noma abanzi (8-12mm), kanye namaphethini agobile (S no-W). Ngokuyinhloko akhiwe ngama-chromium alloys, lawa ma-alloy aqukethe ne-manganese, i-molybdenum, i-niobium, i-nickel, ne-boron. Ama-carbide asatshalaliswa ngephethini ye-fibrous esakhiweni se-metallographic, kanye nama-fiber asebenza ngokuqondile ebusweni. Ngokuqukethwe kwe-carbide okungu-40-60%, ubulukhuni obuncane bungafinyelela ngaphezu kwe-HV1700, kanti ubulukhuni bomphezulu bungafinyelela ku-HRC58-62. Amapuleti ensimbi angagugi ahlukaniswe kakhulu ngezigaba ezintathu: inhloso ejwayelekile, engagugi kanye nengagugi kakhulu. Ubukhulu obuphelele bamapuleti ensimbi angagugi bungaba buncane njengo-5.5 (2.5+3) mm kanye nobukhulu obungu-30 (15+15) mm. Amapuleti ensimbi angagugi angagoqwa abe amapayipi angagugi anobubanzi obuncane be-DN200, futhi angacutshungulwa abe yizindololwane ezingagugi, ama-tee angagugi kanye nezinciphisi ezingagugi.
