I-S355 J0 Spiral Seam Welded Pipe iyathengiswa
Siyajabula ukuzazisa kuwe umkhiqizo wethu wakamuva,S355 J0 Spiral Steel Pipe, okungukuthi ipayipi elivuthayo le-welded elenzelwe ikhoyili yensimbi ephezulu ye-strip njengento eluhlaza. Amapayipi ethu we-Weld WELDED akhiqizwa kusetshenziswa inqubo ethuthukisiwe ye-auto ezenzakalelayo ye-twin-wire engaphakathi ye-arc welding.

I-S355 J0 Spiral Steel Tube yakhiwa ngokunemba nobuhle bokuqinisekisa ukuqina nokuthembeka ekusebenzeni kwayo. Kuyipuleti yensimbi ephansi ephansi, esetshenziswa kabanzi ekukhiqizeni imishini, imishini yezokwakha, imishini yezokuhwebelana, imishini yokumbiwa kwezimayini, imishini yezimbali, ama-cranes, ama-generes, ama-generator, ama-generator, ama-beatings kanye nezinye izimboni. Amagobolondo, izingxenye zokucindezela, ama-turbines athumba, izingxenye ezishumekiwe, izingxenye zemishini.
Enye yezinto eziphambili ze-S355 J0 Spiral Tube yensimbi yinzuzo yayo ehlukahlukene. Amapayipi ensimbi e-Spiral asetshenziswa kabanzi futhi angahlangabezana nezidingo ezahlukahlukene zezimboni ezahlukahlukene. Noma ngabe kuyimishini esindayo noma amaphrojekthi wengqalasizinda, leli payipi linikeza ukusebenza okuhlukile namandla, okwenza kube yinto elungele izicelo ezifunwayo.

EConggzhou Spiral Steel Pipe Group Co, Ltd, siyaziqhenya ngamakhono ethu okukhiqiza isimo sezwe. Ngemigqa engu-13 yokukhiqiza yamapayipi ensimbi, nemigqa engu-4 yokukhiqiza yokulwa nokugqwala kanye nezinyathelo zokufakelwa okushisayo, siphenduke umphakeli oholayo embonini. Ubuchwepheshe bethu obuthuthukisiwe bokukhiqiza busenza sikwazi ukukhiqiza amapayipi ensimbi ane-thrarione
Sizibophezele ekuhlinzekeni imikhiqizo esezingeni eliphezulu ehlangabezana namazinga aphezulu embonini. Iqembu lethu labasebenzi abanamakhono liqinisekisa ukuthi ipayipi ngalinye lithola ukuhlolwa kwekhwalithi okuqinile kwamandla, ukuqina kanye nokusebenza. Ngaphezu kwalokho, sibeka phambili ukwaneliseka kwamakhasimende futhi sinikeze insizakalo enhle kakhulu yokuthengisa kumakhasimende ethu abalulekile.
Nge-S355 J0 Spiral Pipe yethu, ungathembela kwikhwalithi ephezulu kanye nokwethenjwa okumele imikhiqizo yethu. Noma ngabe usemishini esindayo noma embonini yezokwakha, amapayipi ethu ensimbi angeqa okulindelwe futhi alethe imiphumela emihle.
Khetha i-Conggzhou Spiral Steel Pipe Group Co, Ltd. yazo zonke izidingo zakho zensimbi yensimbi. Umlingani nathi namhlanje futhi uthole ikhwalithi engenakuqhathaniswa kanye nokwethenjwa kwemikhiqizo yethu.
Ukuhlolwa kweHydrostatic
Ubude bepayipi ngalinye buzovivinywa ngumenzi ngengcindezi ye-hydrostatic ezokhiqiza odongeni lwamapayipi ingcindezi engaphansi kwamandla ka-60% acacisiwe amancane okushisa avumayo ekushiseni kwegumbi. Ingcindezi izonqunywa yi-equation elandelayo:
P = 2st / d
Ukuhlukahluka okuvumelekile ezinsimbi nasezilinganiso
Ubude bepayipi ngalinye buzosindwa ngokwehlukana futhi isisindo salo ngeke bahlukane ngaphezu kwe-10% ngaphezulu noma ngo-5.5% ngaphansi kwesisindo sayo sethiyori, kubalwa kusetshenziswa ubude baso kanye nesisindo sayo ngeyunithi yayo ngayinye ubude
Ububanzi bangaphandle ngeke buhluka kakhulu kune- ± 1% kusuka kububanzi obucacisiwe be-off
Ubukhulu bodonga nganoma yiliphi iphuzu ngeke bungabi ngaphezu kwe-12,5% ngaphansi kobukhulu bedonga olubekiwe
