Kwa-Cangzhou Spiral Steel Pipe Group Co., Ltd., siyaziqhenya ngamakhono ethu okukhiqiza asezingeni eliphezulu.Ngemigqa yokukhiqiza engu-13 yamapayipi ensimbi e-spiral, kanye nemigqa yokukhiqiza engu-4 yezinyathelo zokulwa nokugqwala kanye nezinyathelo zokushisa ezishisayo, sesibe umphakeli ohamba phambili embonini.Ubuchwepheshe bethu obuthuthukisiwe bokukhiqiza busenza sikwazi ukukhiqiza amapayipi ensimbi avunguzayo anobubanzi obungu-Φ219-Φ3500mm kanye nogqinsi lwezindonga lwe-6-25.4mm.
Sizibophezele ekuhlinzekeni ngemikhiqizo yekhwalithi ephezulu ehlangabezana namazinga aphezulu embonini.Ithimba lethu lochwepheshe abanamakhono liqinisekisa ukuthi ipayipi ngalinye lihlolwa ngokucophelela ikhwalithi ukuze lithole amandla, ukuqina nokusebenza.Ngaphezu kwalokho, sibeka phambili ukwaneliseka kwamakhasimende futhi sinikeza isevisi enhle kakhulu yangemva kokuthengisa kumakhasimende ethu abalulekile.
Ngepayipi lethu le-S355 J0 Spiral Steel, ungathembela kwikhwalithi ephezulu nokuthembeka umkhiqizo wethu omele wona.Kungakhathaliseki ukuthi usembonini yemishini esindayo noma yezokwakha, amapayipi ethu ensimbi ezungezayo azodlula okulindele futhi alethe imiphumela evelele.
Khetha i-Cangzhou Spiral Steel Pipe Group Co., Ltd. kuzo zonke izidingo zakho zepayipi lensimbi elivunguzayo.Uzakwethu namuhla futhi ujabulele ikhwalithi engenakuqhathaniswa nokuthembeka kwemikhiqizo yethu.
Ukuhlolwa kwe-Hydrostatic
Ubude bepayipi ngalinye kufanele buhlolwe ngumenzi kumfutho we-hydrostatic ozokhiqiza odongeni lwamapayipi ingcindezi engekho ngaphansi kuka-60% wamandla esivuno amancane ashiwo ekamelweni lokushisa.Ingcindezi izonqunywa yi-equation elandelayo:
P=2St/D
Ukwehluka Okuvumelekile Kwesisindo Nobukhulu
Ubude bepayipi ngalinye buzokalwa ngokwehlukana futhi isisindo salo angeke sihluke ngaphezu kuka-10% ngaphezulu noma u-5.5% ngaphansi kwesisindo salo esicatshangelwayo, kubalwe kusetshenziswa ubude balo nesisindo salo ngobude beyunithi ngayinye.
Idayamitha yangaphandle akumele ihluke ngaphezu kuka-±1% ukusuka kububanzi obukhethekile obushiwo bangaphandle
Ukujiya kodonga kunoma iyiphi indawo akufanele kube ngaphezu kuka-12.5% ngaphansi kogqinsi olushiwo
