Hydrostatic Test
Cov yeeb nkab yuav tsum tiv taus qhov kev sim hydrostatic yam tsis muaj qhov xau los ntawm cov vuam seam lossis lub cev yeeb nkab
Jointers yuav tsum tsis txhob sim hydrostatically, yog hais tias cov feem ntawm cov yeeb nkab siv nyob rau hauv kos cov jointers tau ua tiav hydrostatically kuaj ua ntej kev koom tes ua hauj lwm.
Nrog rau kev tsom mus rau qhov zoo, peb tsuas yog siv cov ntaub ntawv zoo tshaj plaws hauv peb cov txheej txheem tsim khoom.Cov ntaub ntawv tseem ceeb siv nyob rau hauv peb cov kav welded kav yog Q195, Q235A, Q235B, Q345, thiab lwm yam. Cov ntaub ntawv zoo no ua kom peb cov kav dej ua tau raws li cov qauv kev lag luam thiab tuaj yeem tiv taus huab cua.
Ntawm Cangzhou Spiral Steel Pipe Group Co., Ltd., peb muab cov neeg siv khoom txaus siab ua ntej thiab siv zog los muab cov khoom zoo tshaj plaws uas ua tau raws li koj cov kev xav tau tshwj xeeb.Lub tuam txhab muaj 13 kauv steel yeeb nkab ntau lawm kab thiab 4 tshwj xeeb los tiv thaiv corrosion thiab thermal rwb thaiv tsev ntau lawm kab.Nrog cov khoom siv siab heev, peb tuaj yeem tsim cov kauv submerged arc welded kauv steel kav nrog diameters ntawm Φ219 txog Φ3500mm thiab phab ntsa thicknesses ntawm 6-25.4mm.
Peb cov kauv welded carbon steel kav muaj ntau yam zoo rau ntau yam kev lag luam.Lub cev muaj zog thiab kav ntev ntawm peb cov kav dej ua rau lawv muaj kev xaiv zoo tshaj plaws rau kev tsim kho vaj tse xws li kev siv dej, roj thiab roj tsheb thauj mus los, thiab kev tsim kho.Tsis tas li ntawd, peb cov kav dej muaj corrosion-resistant, ua kom lub neej ntev thiab kev ntseeg siab nyob rau hauv ib puag ncig hnyav.
