Cov yam ntxwv tuag: Qhia qhov tsis sib xws lossis tsis tu ncua hauv zos indentation thiab nqaij ntawm qhov ntev ntawm cov yeeb nkab steel. Cov duab yog nuclear, sawb, kab rov tav siab raug mob, tilted daim tawv nqaij, fragmented, hlau dumb-shaped, thiab lwm yam.
ua rau:
① Qhov saum npoo ntawm cov rolls tiav ntawm lub tensor yog nplaum rau saum npoo ntawm yob.
② Scars lossis lwm lub cev txawv teb chaws raug nias rau ntawm cov yeeb nkab steel kom poob.
③ Lub thermal steel yeeb nkab raug mob los yog khawb.
④ Trocaying raug mob thiab luam tawm los ntawm transverse txav los yog sawing ntaus ntawv.
tus txiav txim:
General tube: Wall thickness ≤8mm indentation depth does not exceed 90% of negative deviations, and wall thickness>80% ntawm 80% ntawm qhov tob ntawm 8mmm indentation yuav tsum tsis pub tshaj 1.0mm.
Boiler raj: Tus nqi siab tshaj plaws ntawm phab ntsa thickness yog 0.6mm.
Roj suite: Qhov tob indentation yuav tsum tsis pub tshaj ib nrab ntawm phab ntsa thickness bias. Qhov siab tshaj plaws tus nqi ntawm qhov tob ntawm S Loj dua los yog sib npaug rau 10mm tsis tshaj 0.6mm, thiab qhov tob ntawm qhov siab tshaj plaws ntawm S<<10mm does not exceed 0.5mm.
