Ubulukhuni bepayipi lensimbi bubhekisela emandleni ezibonakalayo okumelana noshintsho ngaphansi kwamandla angaphandle. Ubulukhuni bungenye yezinkomba ezibalulekile zokusebenza okubonakalayo.
Ekukhiqizweni nasekusetshenzisweni kwamapayipi ensimbi, ukuzimisela kobulukhuni babo kubaluleke kakhulu. Ubulukhuni bamapayipi ensimbi bungalinganiswa ngabahloli bama-hardness ahlukahlukene njenge-rockell, brinell, futhi ama-vickers akhiqizwa yi-laizhou laihua Test Instrument Factory, engenziwa ngokwezifiso njengoba kudingeka. Izindlela eziphambili zokulinganisa zifaka okulandelayo:
1
I-Rocwell Hardness Test njengamanje iyindlela esetshenziswa kakhulu, phakathi kwayo i-HRC ingeyesibili kuphela ku-Brinell Hardness HB kwi-Insimbi Pipe Standard. Kukala ukujula kwe-induction futhi kungasetshenziswa ukukala izinto zensimbi kusuka kuthambile kakhulu kube nzima kakhulu. Kulula kunendlela yokuhlola i-Brinell.
2. I-Brinell Hardness Test Test
Indlela yokuhlola ukuvivinyanisa i-Brinell Hartness nayo isetshenziswa kabanzi ensimini yezimboni. Isetshenziswa kabanzi kumazinga wepayipi ensimbi engenamthungo. Ubulukhuni bezinto ezibonakalayo buvame ukuvezwa ububanzi bokubhalwa phansi. Inembile futhi ilungele, kepha ayisebenzi kumapayipi ensimbi anzima noma anciphile.
I-3. Indlela yokuhlola ubunzima
Ukuhlolwa kobunzima be-Vickers kusetshenziswa kabanzi. Inezinzuzo eziphambili zezindlela zeBrinell ne-Rocwell zokuhlola, kepha zehlula ububi bazo eziyisisekelo. Ilungele ukuhlolwa kobulukhuni bezinto ezahlukahlukene, kepha ayilungele amasampula ngamawazi amancane. Akulula njengendlela yokuhlola i-RocKwell futhi akuvamile ukusetshenziswa kumazinga wepayipi ensimbi.
