1. Ipulasitiki
I-Plasticity ibhekisela ekhonweni lensimbi ukukhiqiza ukuguqulwa kwepulasitiki (ukuguqulwa okuhlala njalo) ngaphandle kokulimala ngaphansi komthwalo.
2. Ubulukhuni
Ukuqina yigeji yokuthi insimbi iqine noma ithambile kangakanani.Kule mpilo ekukhiqizeni indlela yokulinganisa ubulukhuni iyona evame ukusetshenziswa kakhulu endleleni yobulukhuni be-indenter, iwukusebenzisa ukwakheka okuthile kwejiyomethri yekhanda le-indenter ngaphansi komthwalo othile ebusweni bensimbi okufanele ihlolwe, ngokusho izinga le-indenter ukuze kunqunywe inani lobunzima.
Izindlela ezisetshenziswa kakhulu iBrinell hardness (HB), ukuqina kwe-Rockwell (HRA, HRB, HRC) kanye nokuqina kwe-Vickers (HV) nezinye izindlela.
3. Ukukhathala
Amandla, ipulasitiki nobulukhuni yizinkomba zezakhiwo zemishini yensimbi ngaphansi komthwalo omile.Eqinisweni, izingxenye eziningi zomshini zisebenza ngaphansi kwemithwalo ye-cyclic, futhi ukukhathala kungenzeka ngaphansi kwalezi zimo.Indlela nayo idinga ukuba nesinye isimo sesigaba sepayipi lensimbi elimise okukhethekile.
Ipayipi lensimbi elinengcindezi ephansi (GB/T3092-1993) yaziwa nangokuthi ipayipi elishiselwe elivamile, elivame ukubizwa ngokuthi ipayipi elimnyama.Kuyipayipi elishiselwe insimbi elisetshenziselwa ukudlulisa amanzi, igesi, umoya, uwoyela, umusi wokushisisa kanye nolunye uketshezi olujwayelekile olunomfutho ophansi kanye nezinye izinjongo.Ugqinsi lwamapayipi ensimbi luhlukaniswe ipayipi elivamile lensimbi kanye nepayipi lensimbi eliqinisiwe.Ifomu lokuphela kwepayipi lihlukaniswe nge-non-rebar steel tube (ithubhu elikhanyayo) kanye ne-rebar steel tube.Ukucaciswa kweshubhu lensimbi kukhonjiswe ngobubanzi obuncane (mm), okuwukulinganiswa kobubanzi bangaphakathi.Kuyisiko ukusebenzisa amayintshi, njenge-11/2.Ipayipi lensimbi elishiselwe elisetshenziselwa ukuthuthwa kwamanzi anengcindezi ephansi lisetshenziswa kakhulu njengepayipi langempela lepayipi lensimbi elishiselwe elisetshenziselwa ukuthuthwa koketshezi olunomfutho ophansi.
Ipayipi lensimbi eliphekwe ngensimbi yokuthutha uketshezi olunengcindezi ephansi (GB/T3091-1993) yaziwa nangokuthi ipayipi lensimbi elishiselwe ngogesi, elivame ukubizwa ngokuthi ipayipi elimhlophe.Idiphu elishisayo elishiselwe (i-welding yesithando somlilo noma ukushisela ngogesi) ipayipi lensimbi elisetshenziselwa ukuhambisa amanzi, igesi, uwoyela womoya, ukushisa isitimu, amanzi afudumele kanye nolunye uketshezi oluvamile olunomfutho ophansi noma ezinye izinjongo.Ugqinsi lwamapayipi ensimbi luhlukaniswe ipayipi elivamile lensimbi nepayipi lensimbi eliqinile.Ukuphela kwepayipi kuhlukaniswe ipayipi lensimbi elikhangayo ngaphandle kwentambo kanye nepayipi lensimbi elinentambo.
