Iipleyiti zentsimbi ezingagugiyo ziqulathe ipleyiti yentsimbi enekhabhoni ephantsi kunye nomaleko ongagugiyo we-alloy, kunye nomaleko ongagugiyo we-alloy ngokubanzi uquka i-1/3 ukuya kwi-1/2 yobukhulu obupheleleyo. Ngexesha lokusebenza, izinto ezisisiseko zibonelela ngeempawu ezibanzi ezifana namandla, ukuqina, kunye nokuguquguquka ukumelana namandla angaphandle, ngelixa umaleko ongagugiyo we-alloy ubonelela ngokumelana nokugugiyo okwenzelwe iimeko ezithile zokusebenza.
Umaleko omelana nokuguguleka kwe-alloy kunye nezinto ezisisiseko zibotshelelwe ngesinyithi. Kusetyenziswa izixhobo ezikhethekileyo kunye nenkqubo yokuwelda ezenzekelayo, ucingo lwe-alloy oluqinileyo noluzikhuselayo luhlanganiswa ngokulinganayo kwizinto ezisisiseko. Umaleko odibeneyo unokuba ngumaleko omnye, emibini, okanye emininzi. Ngenxa yokwahluka kwemilinganiselo yokuguguleka kwe-alloy, imifantu efanayo enqamlezileyo iyavela ngexesha lenkqubo yokulamina, uphawu lweepleyiti zentsimbi ezimelana nokuguguleka.
Umaleko omelana nokuguguleka kwe-alloy wenziwe ikakhulu yi-chromium alloy, kunye nezinye izinto ezidibanisayo ezifana ne-manganese, i-molybdenum, i-niobium, kunye ne-nickel zongeziweyo. Ii-carbides kwisakhiwo se-metallographic zi-fibrous, kunye neefayibha ezijolise ngqo kumphezulu. Ubulukhuni be-carbide bunokufikelela ngaphezulu kwe-HV 1700-2000, kwaye ubunzima bomphezulu bunokufikelela kwi-HRC 58-62. Ii-carbides ze-alloy zizinzile kakhulu kumaqondo obushushu aphezulu, zigcina ubulukhuni obuphezulu kunye nokumelana okuhle kwe-oxidation, okuvumela ukusebenza ngokupheleleyo kumaqondo obushushu afikelela kwi-500°C.
Umaleko omelana nokuguguleka ungabonakala kwiipateni ezimxinwa (2.5-3.5mm) okanye ezibanzi (8-12mm), kunye neepateni ezigobileyo (S kunye ne-W). Ezi ntlobo ze-alloy zenziwe ngokuyintloko zii-chromium alloys, zikwaqulathe i-manganese, i-molybdenum, i-niobium, i-nickel, kunye ne-boron. Ii-carbides zisasazwa kwipateni ye-fibrous kwisakhiwo se-metallographic, kunye neefayibha ezihamba ngokuthe nkqo kumphezulu. Ngomxholo we-carbide we-40-60%, ubunzima obuncinci bunokufikelela ngaphezulu kwe-HV1700, kwaye ubunzima bomphezulu bunokufikelela kwi-HRC58-62. Iiplate zentsimbi ezimelana nokuguguleka zahlulwe ngokubanzi zibe ziindidi ezintathu: ezisetyenziselwa injongo ngokubanzi, ezimelana nokuchaphazeleka kunye nezimelana nobushushu obuphezulu. Ubukhulu obupheleleyo beeplate zentsimbi ezimelana nokuguguleka bunokuba buncinci njenge-5.5 (2.5+3) mm kwaye bube bukhulu njenge-30 (15+15) mm. Iipleyiti zentsimbi ezingagugiyo zinokusongwa zibe yimibhobho engagugiyo enobubanzi obuncinci be-DN200, kwaye zinokucutshungulwa zibe ziingqiniba ezingagugiyo, ii-tee ezingagugiyo kunye nezinciphisi ezingagugiyo.
