Ishubhu Ejikelezayo ye-Q235B
Izindinganiso ezisetshenziswa kakhulu zamapayipi ensimbi ajikelezayo ngokuvamile zihlukaniswe kanje: SY/T5037-2000 (Izinga loMnyango, elibizwa nangokuthi ipayipi lensimbi elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe lamapayipi okuthutha uketshezi ajwayelekile), GB/T9711.1-1997 (Izinga likazwelonke, elibizwa nangokuthi ipayipi lensimbi elidluliselwayo embonini kawoyela negesi Ingxenye yokuqala yezimo zokulethwa kobuchwepheshe: Ipayipi lensimbi lebanga A (ipayipi lensimbi lebanga B lebanga B liyadingeka kakhulu), API-5L (i-American Petroleum Institute, elibizwa nangokuthi ipayipi lensimbi elihlanganisiwe; elihlukaniswe ngamabanga amabili: PSL1 kanye ne-PSL2), SY/T5040-92 (Ipayipi lensimbi elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe).
(1) Izinto zokusetshenziswa ziyizikhoyili zensimbi eziqoshiwe, izintambo zokushisela, kanye ne-fluxes. Kudingeka ukuhlolwa okuqinile ngokomzimba nangokwekhemikhali ngaphambi kokutshala imali.
(2) Inhlanganisela yezinqe zekhanda nomsila wensimbi eyisikwele, kusetshenziswa ukushisela kwe-arc engaphansi komhlaba enentambo eyodwa noma enentambo ezimbili, ngemva kokugoqana nepayipi lensimbi, ukushisela kwe-arc engaphansi komhlaba okuzenzakalelayo kusetshenziselwa ukushisela ukulungisa.
(3) Ngaphambi kokwakheka, umcu udlula ekulinganisweni, ekusikweni komphetho, ekuklanyweni komphetho, ekuhlanzweni nasekudlulisweni komphezulu, kanye nasekuphathweni kokugoba ngaphambi kokufakwa.
(4) Igeyiji yokucindezela kokuxhumana kagesi isetshenziselwa ukulawula ingcindezi yamasilinda ezinhlangothini zombili zomhambisi ukuqinisekisa ukuhanjiswa okubushelelezi komcu.
(5) Sebenzisa ukulawula kwangaphandle noma ukwakha umqulu wokulawula kwangaphakathi.
(6) Idivayisi yokulawula igebe lokushisela isetshenziselwa ukuqinisekisa ukuthi igebe lokushisela lihlangabezana nezidingo zokushisela, futhi ububanzi bepayipi, inani lokungahambisani kahle kanye negebe lokushisela kulawulwa ngokuqinile.
(7) Kokubili ukushisela kwangaphakathi kanye nokushisela kwangaphandle kusebenzisa umshini wokushisela kagesi waseMelika iLincoln wokushisela i-arc enentambo eyodwa noma enentambo ephindwe kabili, ukuze kutholakale imininingwane yokushisela ezinzile.
(8) Ama-weld ahlolwa yithuluzi lamaphutha elizenzakalelayo le-ultrasonic eliqhubekayo eliku-inthanethi, eliqinisekisa ukumbozwa kokuhlolwa okungabhubhisi okungu-100%.
(9) Sebenzisa umshini wokusika we-air plasma ukuze usike ipayipi lensimbi libe yizicucu ngazinye.
(10) Ngemva kokusikwa kube amapayipi ensimbi eyodwa, amapayipi ensimbi amathathu okuqala ebhetshi ngayinye kufanele adlule ohlelweni lokuhlola lokuqala oluqinile ukuqinisekisa ukuthi inqubo yokwenza amapayipi iyafaneleka ngaphambi kokuba isetshenziswe ngokusemthethweni.
(11) Izingxenye ezinezimpawu zokubona amaphutha e-sonic eziqhubekayo kuma-welds zihlolwa kabusha nge-ultrasound kanye ne-X-ray ngesandla.
(12) Amapayipi lapho imithungo yokushisela yensimbi eyisicaba kanye namajoyinti anomumo we-D ahlangana khona nemithungo yokushisela ejikelezayo konke kuhlolwa yithelevishini ye-X-ray noma ukuqopha.
(13) Ipayipi ngalinye lensimbi lihlolwa ngengcindezi ye-hydrostatic, bese ingcindezi ithatha uphawu lwe-radial. Ingcindezi nesikhathi sokuhlola kulawulwa ngokuqinile yidivayisi yokuthola i-hydraulic microcomputer yepayipi lensimbi. Amapharamitha okuhlola aphrintwa futhi aqoshwe ngokuzenzakalelayo.
(14) Umshini wokulungisa amapayipi, ukuze ukuma kobuso bokuphela, i-engeli ye-bevel kanye nomphetho ongabonakali kulawulwe ngokunembile.
Ipayipi lensimbi elihlanganisiwe elingaphansi kwe-arc elihlanganisiwe (SY5036-83) lokuthuthwa koketshezi oluthwala ingcindezi lisetshenziswa kakhulu kumapayipi okuthutha uwoyela negesi yemvelo; ipayipi lensimbi elihlanganisiwe elingaphansi kwe-arc elihlanganisiwe elingaphezu kwe-arc elihlanganisiwe (SY5038-83) lokuthuthwa koketshezi oluthwala ingcindezi, kusetshenziswa indlela yokuwelda yama-lap aphindaphindayo aphezulu. Ipayipi lensimbi elihlanganisiwe elingaphansi kwe-arc elihlanganisiwe elingaphezulu kwe-arc elihlanganisiwe lokuthuthwa koketshezi oluthwala ingcindezi. Ipayipi lensimbi linomthamo oqinile wokuthwala ingcindezi kanye ne-plasticity enhle, elula ukuwelda nokucubungula. Ngokuvamile, ipayipi lensimbi elihlanganisiwe elingaphansi kwe-arc elihlanganisiwe (SY5037-83) lokuthuthwa koketshezi olungaphansi kwengcindezi lenziwa ngokuwelda okuzenzakalelayo okungaphansi kwe-arc okuhlanganisiwe okuphindwe kabili noma ukuwelda okungaphansi kwe-arc kwamanzi, ipayipi lensimbi elihlanganisiwe elingaphansi kwe-arc elihlanganisiwe lokudlulisa uketshezi olujwayelekile oluphansi olufana negesi, umoya kanye nomusi.
