Rau cov engineers hauv aerospace propulsion thiab siab - ntsuas ntsuas,GH4169 seamless steel tubingyog ib feem tseem ceeb. Txawm li cas los xij, ntau cov khoom lag luam muaj "kev lag luam- qib" tubings raug kev txom nyem los ntawm ob qhov tsis xws luag:
Internal oxidation (scaling):Cov txheej txheem txheej txheem annealing tawm ib txheej ntawm cov oxide dub hauv lub raj. Nyob rau hauv siab - ntws- tus nqi roj, txheej oxide no tuaj yeem tawg tawm, txhaws qhov ntsuas qhov tseeb thiab cov roj injectors.
Tsis zoo concentricity (tsis sib xws phab ntsa thickness): Cov phab ntsa tuab tsis sib haum ua rau thaj tsam "cov ntsiab lus tsis muaj zog." Nyob rau hauv qhov kev kub ntxhov siab heev (txog 700 bar), cov ntsiab lus tsis muaj zog tuaj yeem dhau los ua qhov pib ntawm cov yeeb nkab tawg, thaum kawg ua rau muaj kev puas tsuaj loj.
NtawmGnee Steel, peb tshem tawm cov kev tsim khoom no los ntawm cov txheej txheem tshwj xeeb, ua kom muaj kev ncaj ncees thiab xoom- tsis zoo.
