    Kev Xeem Xeem

    Hydrostatic xeem

    Cov yeeb nkab kom tiv taus qhov kev sim hydrostatic yam tsis muaj qhov xau los ntawm cov hlua khi los yog cov yeeb nkab lub cev. Jointers tsis tas yuav tsum tau kuaj hydrostatic muab cov yeeb nkab seem siv tau zoo kuaj.

    Khoov xeem

    Tsis muaj kab nrib pleb yuav tsum tshwm sim nyob rau hauv ib feem ntawm daim ntawv xeem thiab tsis muaj qhov qhib qhov vuam yuav tsum tshwm sim.

    Flattening xeem

    Kev lees txais cov qauv rau kev kuaj flattening yuav tsum yog:

    • EW kav dej D <12.750 hauv:
    • X60 T 500 in. Yuav tsum tsis txhob qhib qhov vuam ua ntej qhov kev ncua deb ntawm daim hlau yog tsawg dua 66% ntawm qhov qub sab nraud txoj kab uas hla. Rau txhua qib thiab phab ntsa, 50%.
    • Rau cov yeeb nkab nrog D / t> 10, yuav tsum tsis txhob qhib qhov vuam ua ntej qhov kev ncua deb ntawm daim hlau yog tsawg dua 30% ntawm qhov qub sab nraud.
    • Rau lwm qhov ntau thiab tsawg xa mus rau tag nrho API 5L specification.

    CVN cuam tshuam kuaj rau PSL2

    Ntau PSL2 cov yeeb nkab loj thiab qib xav tau CVN. Seamless yeeb nkab yuav tsum tau kuaj hauv lub cev. Welded yeeb nkab yog yuav tsum tau kuaj nyob rau hauv lub cev, yeeb nkab weld thiab tshav kub-cuam tshuam cheeb tsam. Xa mus rau tag nrho API 5L specification rau daim duab ntawm qhov ntau thiab tsawg thiab qib thiab yuav tsum tau absorbed zog qhov tseem ceeb.
