| Ubukhulu bodonga lwegama (mm) | 2.0, 2.5, 2.8, 3.2, 3.5, 3.8, 4.0, 4.5 |
1.Amandla e-Tensile (σb): Amandla aphezulu (Fb) isifanekiso esiba ngaphansi kokungezwani lapho sidonswa, ahlukaniswe ingcindezi (σ) etholwe endaweni yasekuqaleni ye-cross-sectional (So) yesifanekiso, abizwa ngokuthi amandla aqinile ( σb), ku-N/mm2 (MPa). Imele umthamo omkhulu wezinto zensimbi ukumelana nomonakalo ngaphansi kwengcindezi. Kuphi: Fb - amandla amakhulu isifanekiso esimelana nawo lapho sidonswa, N (Newton); Ngakho - indawo yokuqala ye-cross-sectional ye-specimen, mm2.
2.iphoyinti lokuvunwa (σs): impahla yensimbi enezinto ezikhiqizayo, ingcindezi lapho isifanekiso singaqhubeka sinwebeka ngaphandle kokunyuka kwamandla (ahlale angashintshi) phakathi nenqubo yokwelula, ebizwa ngokuthi iphoyinti lokuvunwa. Uma amandla ehla, amaphuzu okukhiqiza aphezulu naphansi kufanele ahlukaniswe. Iyunithi yephoyinti lesivuno ngu-N/mm2 (MPa). Iphuzu lesivuno esiphezulu (σsu): ukucindezeleka okukhulu ngaphambi kokuba isifanekiso sikhiqize futhi amandla aqale anciphe; Iphoyinti lesivuno esiphansi (σsl): ingcindezi encane esigabeni sokukhiqiza lapho umphumela wesikhashana wokuqala ungabalwa. Lapho: I-Fs - amandla okukhiqiza (okungashintshi) we-specimen ekucindezelekeni, N (Newton) Ngakho - indawo yoqobo ye-cross-sectional yesifanekiso, mm2.
3.Ukwelulwa ngemva kwekhefu: (σ) Esivivinyweni sokuqina, iphesenti lokukhuphuka kobude besifanekiso ngemva kokukhipha isikali saso siye kubude besikali sangempela kubizwa ngokuthi ukwelulwa. Kuvezwe ngo-σ, iyunithi ithi %. Kuphi: L1 - ubude besampula ngemva kokudonswa kwesampula, mm; L0 - ubude bephimbo lokuqala lesifanekiso, mm.
4.Ukuncipha kwengxenye: (ψ) Ekuhlolweni okuqinile, ukushwabana okuphezulu kwendawo ephambanayo ekushwabaneni kwayo ngemva kokuba isifanekiso sikhishiwe njengephesenti lendawo yokuqala ye-cross-sectional ibizwa ngokuthi i-fractional shrinkage. Kuvezwe ngokuthi ψ, ngo-%. Kuphi: I-S0 - indawo yokuqala ye-cross-sectional yesampula, mm2; I-S1 - indawo encane ephambanayo ekushwabaneni ngemva kokukhishwa kwesampula, mm2.
5.Inkomba yokuqina: ikhono lensimbi ukumelana nokuhlehlisa into eqinile ibe ngaphezulu, okubizwa ngokuthi ubulukhuni. Kuye ngendlela yokuhlola kanye nobubanzi bokusebenza, ubulukhuni bungahlukaniswa ngokuqina kwe-Brinell, ukuqina kwe-Rockwell, ukuqina kwe-Vickers, ukuqina koShore, ukuqina okuncane kanye nobulukhuni bezinga lokushisa eliphezulu. Ngokuba ithubhu ngokuvamile isetshenziswa Brinell, Rockwell, Vickers ubulukhuni ezintathu.
Ukuqina kwe-Brinell (HB): Usebenzisa ibhola lensimbi noma le-carbide lobubanzi obuthile, cindezela amandla okuhlola ashiwo (F) endaweni yesifanekiso, susa amandla okuhlola ngemva kwesikhathi esibekiwe sokubamba, futhi ulinganise ububanzi bokuhlehlisa (L) phezu kwesifanekiso. Inani lobulukhuni be-Brinell yi-quotient etholwe ngokuhlukanisa amandla okuhlola ngendawo eyindilinga yendawo yokuhlehlisa. Kuvezwe njenge-HBS (ibhola lensimbi) ngo-N/mm2 (MPa).
Amapayipi ensimbi ashisayo asetshenziswa kabanzi ekwakheni, emishinini, ezimayini zamalahle, embonini yamakhemikhali, amandla kagesi, izimoto zikaloliwe, imboni yezimoto, imigwaqo emikhulu, amabhuloho, iziqukathi, izikhungo zemidlalo, imishini yezolimo, imishini kaphethiloli, imishini yokuhlola nezinye izimboni zokukhiqiza. .
Ipayipi lensimbi eliphehliwe yipayipi lensimbi elishiselwe elinediphu elishisayo noma indawo efakwe i-electro galvanized. I-galvanization ingakhuphula ukumelana nokugqwala kwamapayipi ensimbi futhi yandise impilo yesevisi. Ipayipi lensimbi elinothayela linokusetshenziswa okunhlobonhlobo, ngaphezu kokusetshenziswa njengepayipi loketshezi olujwayelekile olunomfutho ophansi njengamanzi, igesi nowoyela, liphinde lisetshenziswe njengepayipi lomthombo kawoyela kanye nepayipi likawoyela embonini kawoyela, ikakhulukazi embonini kawoyela. amasimu kawoyela wasolwandle, njengesifudumezi sikawoyela, isibambisi se-condensation kanye ne-distillation yamalahle kanye nesishintshi sokuwasha uwoyela sezinto zokuphekela ngamakhemikhali, nanjengepayipi lohlaka lokusekela izinqwaba zamapayipi e-trestle nemigodi yezimayini, njll.
Ipayipi lamanzi, ipayipi likawoyela, ipayipi lesikafula, uthango lomgwaqo onguthelawayeka, ikhava yeshede, njll.
