Te whakamatautau hydrostatic
Mo nga whakamatautau Hydrostatic paerewa ASTM A106 ka mahia takitahi. me pehea te tatau i nga raraunga o te hydrostatic mo ia rahi?
Hei tauira mo ASTMA106 GrB PSL 2 waro paipa maitai 273*7mm
Ko nga raraunga e tika ana ko: 2*min te kaha tuku *0.6 *te matotoru/ Diameter
ka penei:
2*245*0.6*7/273=7.5 MPa
Kei te mohio koe inaianei?

Whakaritenga Whakamatau
Hei taapiri atu ki te whakarite i te hanganga matū me nga taonga miihini, ka mahia nga whakamatautau hydrostatic takitahi, ka mahia nga whakamatautau mura me te papatahi. . I tua atu, kei reira etahi whakaritenga mo te microstructure, te rahi o te witi, me te paparanga decarburization o te paipa maitai oti.
