Amapuleti ensimbi angagugi ahlanganisa ipuleti lensimbi elinekhabhoni ephansi kanye nongqimba oluqinile olungagugi, olunongqimba oluqinile olungagugi ngokuvamile oluhlanganisa u-1/3 kuya ku-1/2 wengqikithi yogqinsi. Ngesikhathi sokusebenza, izinto eziyisisekelo zinikeza izici eziphelele njengamandla, ukuqina, kanye ne-ductility ukumelana namandla angaphandle, kuyilapho ungqimba olumelana nokugqoka kwe-alloy lunikeza ukumelana nokuguga okuhambisana nezimo ezithile zokusebenza.
I-alloy-resistant layers kanye ne-base material iboshwe nge-metallurgically. Ukusebenzisa imishini ekhethekile kanye nenqubo yokushisela okuzenzakalelayo, ukuqina okuphezulu, i-self-shielding alloy wire ihlanganiswe ngokulinganayo kusisekelo. Isendlalelo esiyinhlanganisela singaba isendlalelo esisodwa, ezimbili, noma eziningi. Ngenxa yezilinganiso ezihlukene ze-alloy shrinkage, imifantu evundlile efanayo iyakhula phakathi nenqubo yokucwenga, uphawu oluphawulekayo lwamapuleti ensimbi angagugi.
Ungqimba olumelana nokugqokwa kwengxubevange ngokuyinhloko lwakhiwe ngengxubevange ye-chromium, nezinye izakhi ze-alloying ezifana ne-manganese, i-molybdenum, i-niobium, ne-nickel. Ama-carbides esakhiweni se-metallographic ane-fibrous, nemicu eqondiswe phezulu phezulu. I-carbide microhardness ingafinyelela ngaphezu kwe-HV 1700-2000, futhi ubulukhuni bobuso bungafinyelela ku-HRC 58-62. Ama-alloy carbides azinzile kakhulu emazingeni okushisa aphezulu, agcina ubulukhuni obuphezulu kanye nokumelana ne-oxidation okuhle kakhulu, okuvumela ukusebenza okugcwele ngaphakathi kwamazinga okushisa afinyelela ku-500°C.
Ungqimba olungagugi lungavela kumaphethini amancane (2.5-3.5mm) noma ububanzi (8-12mm), kanye namaphethini agobile (S kanye no-W). Ngokuyinhloko akhiwe ama-alloys e-chromium, lawa ma-alloys aqukethe i-manganese, i-molybdenum, i-niobium, i-nickel, ne-boron. Ama-carbides asatshalaliswa ngephethini ene-fibrous esakhiweni se-metallographic, nemicu egijima i-perpendicular to surface. Ngokuqukethwe kwe-carbide okungama-40-60%, ubulukhuni obuncane bungafinyelela ngaphezu kwe-HV1700, futhi ubulukhuni bobuso bungafinyelela ku-HRC58-62. Amapuleti ensimbi angagqoki ahlukaniswe kakhulu abe izigaba ezintathu: inhloso evamile, ukumelana nokushayisana kanye nokumelana nezinga lokushisa eliphezulu. Ugqinsi oluphelele lwamapuleti ensimbi angakwazi ukuguga lungaba luncane lube ngu-5.5 (2.5+3) mm futhi lube ugqinsi lube ngu-30 (15+15) mm. Amapuleti ensimbi angagugi angagingqwa abe amapayipi angagugi anobubanzi obuncane obungu-DN200, futhi angacutshungulwa abe izindololwane ezingagugi, amateyi avikela ukugqokwa kanye nezinciphisi ezingagugi.
