Hydrostatic Kev Ntsuam Xyuas
Cov yeeb nkab los tiv thaiv qhov kev kuaj hydostatic yam tsis muaj kev lom los ntawm Weld Seam lossis Yeeb Nkab Lub Cev. Cov tub rog tsis tas yuav muaj hydrostatic kuaj muab cov yeeb nkab seem uas siv tau sim ua tiav.
Khoov Xeem Ntawv
Tsis muaj kab nrib pleb yuav tshwm sim hauv ib feem ntawm daim xeem thiab tsis qhib ntawm Weld yuav tshwm sim.
Plhaw kev kuaj
Kev lees txais cov txheej txheem rau cov kev kuaj mob ntsws yuav tsum yog:
- EW kav d <12.750 hauv:
- X60 nrog t 500in. Yuav tsis muaj qhib ntawm Weld ua ntej qhov kev ncua deb ntawm cov phiaj yog tsawg dua 66% ntawm cov qub sab nraud. Rau txhua qib thiab phab ntsa, 50%.
- Rau cov yeeb nkab nrog D / T> 10, yuav tsis muaj qhib ntawm Weld ua ntej qhov kev ncua deb ntawm cov phiaj yog tsawg dua 30% ntawm cov qub saum lub cheeb.
