Inqubo yokuqeda amapayipi ensimbi iyinqubo ebaluleke kakhulu futhi ebalulekile yokuqeda amaphutha ensimbi, futhi uhlangabezana nokuhlolwa kwekhwalithi yensimbi, ukuqina kokuhlolwa kwekhwalithi, ukuhlolwa okungekho emthethweni, ukuhlolwa okungeyona eyonakalisayo, njll.) Ukugaya, isilinganiso sobude, ukukala, ukupenda, ukuphrinta nezinqubo zokupakisha. Amanye amapayipi ensimbi akhethekile adinga futhi ukuqhuma komhlaba okudutshulwa, ukucubungula imishini, ukwelashwa okulwa nokulwa nokugqwala, njll.
.
⒈ Inhloso yepayipi yensimbi:
① Qeda ukugoba (ukungaqondile) okukhiqizwe yipayipi lensimbi ngesikhathi sokugoqa, ukuthutha, ukwelashwa kokushisa nezinqubo zokupholisa
② Yehlisa amandla entengo yamapayipi ensimbi
⒉ Izinkinga zekhwalithi ezibangelwa yipayipi lensimbi ngesikhathi senqubo eqondile: ezihlobene nemodeli yomshini oqondisayo, ukwakheka komgodi, ukulungiswa komgodi kanye nezimpawu zepayipi lensimbi.
⒊ Izinkinga zekhwalithi yekhwalithi yokuqondisa ipayipi ensimbi
(ii) Ukugaya kwamapayipi wensimbi nokusika iziphambeko kanye nokuvimbela kwabo
⒈ Inhloso yokugaya izici zensimbi engaphezulu kwamapayipi ensimbi: Ukususa amaphutha angaphezulu avunyelwe ukuba khona ngamazinga wepayipi ensimbi kepha kufanele ahlanzeke ekuthuthukiseni ikhwalithi yensimbi.

⒊ Ukugaya okungaphezulu kwensimbi kufanele kuhlangane ngokuvamile lezi zidingo ezilandelayo:
Ngemuva kokulimala okungaphezulu kwepayipi lensimbi, ukulungiswa kodonga kwendawo elungisiwe akunakuba ngaphansi kokuphambuka okungatheni kodonga lwensimbi, kanti ubukhulu bendawo elungisiwe kufanele bahlangabezane nezidingo zobubanzi bepayipi lensimbi.
②homba ingaphezulu lepayipi lensimbi liyindawo, kuyadingeka ukugcina ubuso bomhlaba wepayipi lensimbi njengendawo egobile egobile (i-arc eyeqile). Ukugaya Ukujula: Ububanzi: Ubude = 1: 6: 8
Lapho ukugaya ipayipi lensimbi kuphelele, akufanele kube namamaki we-polygonal aphezulu noma asobala ebusweni bepayipi lensimbi.
Amaphuzu wokugaya angaphezulu komhlaba wepayipi lensimbi ngeke adlule inombolo echazwe kwiZinga.
⒋ Ukulimala okuyinhloko okubangelwa ukugawulwa kwepayipi kwensimbi kufaka phakathi: Ubuso bokuphela kwepayipi lensimbi alikho mpo, kukhona ama-burrs kanye nama-loops, futhi i-bevel angle ayilungile, njll.
⒌ Ukuthuthukisa ukuqondisisa kwepayipi lensimbi nokunciphisa ukweqisa kwepayipi lensimbi kuyizimfuneko zokuqinisekisa ikhwalithi yokusika yepayipi lensimbi. Amapayipi ensimbi anokuqukethwe okuphezulu kwe-alloy, ukusika kwamalangabi kufanele kugwenywe ngangokunokwenzeka ukunciphisa ukwenzeka kokuphela kokuphela kwamapayipi.
(iii) Ukulungiswa kwepayipi kwensimbi yokucubungula kanye nokuvimbela kwabo
Ukucutshungulwa komhlaba we-⒈ I-Steel Kufaka phakathi: Parval Shot Peening, ukugaya okungaphezulu komhlaba kanye nokusebenza kwemishini.
⒉ Inhloso: Ukuqhubeka nokwenza ngcono ikhwalithi ephezulu nokunemba kwamapayipi ensimbi.
⒊ Amathuluzi okugaya okuphelele kobuso bangaphandle kwamapayipi ensimbi afaka ikakhulukazi: amabhande abi, amasondo okugaya kanye namathuluzi womshini wokugaya. Ngemuva kokugaya okuphelele kwepayipi lensimbi, isikali se-oxide ebusweni sepayipi lensimbi singaqedwa ngokuphelele, ukuqedwa komhlaba kwepayipi lensimbi kungathuthukiswa, futhi ingaphezulu lepayipi lensimbi lingasuswa. Ezinye izilima ezincane ezifana nemifantu emincane, imigqa yezinwele, imigodi, imihuzuko, njll.
① Sebenzisa ibhande elibi noma igobho lokugaya ukuze ugaye ngokuphelele indawo yepayipi lensimbi. Izinkinga zekhwalithi eziphambili ezingahle zibangelwe: Isikhumba esimnyama ebusweni bepayipi lensimbi, ubukhulu obukhulu odongeni, izindawo eziphansi (ama-polygons), imigodi, ukushiswa kanye namamaki, njll.
Isikhumba esimnyama ebusweni bepayipi lensimbi kubangelwa yinani lokugaya lincane kakhulu noma imigodi ebusweni bepayipi lensimbi. Ukukhuphula inani lokugaya kungasusa isikhumba esimnyama endaweni yepayipi yensimbi.
③ Ubukhulu obudongeni lwensimbi ipayipi bungabekezeleli ngoba ukuphambuka okungekuhle kokushubane kodonga lwepayipi lensimbi ngokwalo kukhulu kakhulu noma inani lokugaya likhulu kakhulu.
④ Ukushisa ebusweni bepayipi lensimbi kubangelwa ikakhulukazi yingcindezi yokuxhumana ngokweqile phakathi kwesondo lokugaya nangaphezulu kwepayipi lensimbi, ipayipi lensimbi ngokugaya okukodwa, kanye nesondo lokugaya elisetshenzisiwe lilukhuni kakhulu.
⑤ Yehlisa inani lokugaya kwepayipi kwensimbi ngasikhathi sinye. Sebenzisa isondo eligaya lama-coarse lokugaya okunamandla kwepayipi lensimbi nesondo elihle lokugaya lokugaya okuhle. Lokhu akukwazi ukuvikela ukushiswa komhlaba ngepayipi lensimbi, kepha futhi kunciphise amamaki okugqoka akhiqizwa ebusweni bepayipi lensimbi.
⒋ Shot Peening on Steel Pepha Langaphezulu
① I-Steel Pipe Surface Shot Peening ukufiphala i-Iron Shot noma i-Quartz Sand Shot ngosayizi othile ngaphezulu kwepayipi lensimbi ngejubane eliphakemeyo ukuze ukhiphe ubushelelezi bepayipi lensimbi.
②Usayizi nobulukhuni be-sand shot kanye nejubane lomjovo yizici ezibalulekile ezithinta ikhwalithi yokudubula ebusweni yepayipi lensimbi.
⒌ I-Steel Pipe Pour Maching
Amapayipi ensimbi anezidingo ezisezingeni eliphakeme zangaphakathi nangaphandle ezidinga ukucubungula kwemishini.
②Ukunemba okubucayi, ikhwalithi ephezulu yekhwalithi ephezulu kanye namapayipi abunjiwe angenakuqhathaniswa namapayipi asongwe.
Ngamafuphi, inqubo yokuqeda yinqubo ebaluleke kakhulu futhi ebaluleke kakhulu yokuqinisekisa ikhwalithi yamapayipi ensimbi. Ukuqinisa iqhaza kwenqubo yokuqeda kuzokusiza ukuthuthukisa ikhwalithi yamapayipi ensimbi.
