I-20 # umbhobho wentsimbi

I-20 # yentsimbi yentsimbi eboniswe umfanekiso
  • I-20 # umbhobho wentsimbi
  • I-20 # umbhobho wentsimbi
  • I-20 # umbhobho wentsimbi

Inkcazo emfutshane:

Umgangatho ophezulu we-carbon ye-carbon yensimbi yokunganyangeki yesakhiwo sokwakha kunye noomatshini. Izixhobo ze-20 #, ekumgangatho ophezulu we-carbon, yindawo yokuqhushumba yentsimbi.


  • Intlawulo:Idiphozithi engama-30%, i-70% L / C okanye ikopi ye-B / L / L / L / C / C ngasekuqaleni
  • I-Min.OPRErI-1 PC
  • Ubuchule boBone:Uluhlu lwe-Tons yonyaka ka-2008 ye-Pons yombhobho wentsimbi
  • Ixesha lokukhokhela:Iintsuku ezingama-7-14 ukuba zikwisitokhwe, ezingama-30 ukuya kwengama-30 ukuya kwengama-30 zokuvelisa
  • Ukupakisha:Ukudakumba okumnyama, ibhowulo kunye nentloko yombhobho ngamnye; I-OD engaphantsi kwe-219mm kufuneka ipakishe kwi-bundle, kwaye i-bundle nganye engaphezulu kweetoni ezi-2.

    Iimpawu kunye nesicelo

    I-20 # intsimbiyeyokuphakathi ekumgangatho ophezulu-we-carbon carbon seeel, kubanda-ekhutshiwe kwaye kuqhutywa intsimbi. Intsimbi inamandla aphantsi, nokuba nobuhle, iplasitiki kunye ne-weld. Yeyona nto iphambili kwi-carbon esezantsi ye-carbon, ebandayo-ekhutshiwe kwaye eqinile intsimbi. Intsimbi inamandla aphantsi, nokuba nobuhle, iplasitiki kunye ne-weld. Isetyenziselwa ukwenza imibhobho engaxinanga kunye noxinzelelo oluphantsi kunye neemfuno eziphezulu.

    Inzuzo

    I-1. Ixesha lokuhanjiswa: Uluhlu lwee-inventri ezinkulu ziqinisekisa ubuncinci bexesha lokuhanjiswa, ikakhulu kwiintsuku ezingama-5-7.

    2. Ulawulo lweendleko: Izixhobo ezikhoyo kwizandla kunye namava obukhulu Ulawulo lweendleko Masikwazi ukubonelela ngesiseko sesona sixhobo sifanelekileyo sobutyebi kwiimfuno zomthengi

    3. Ubutyebi-Millis Phezulu: bunokubonelela ngesatifikethi semithetho esipheleleyo kunye namaxwebhu esiqinisekiso sokubonisa umgangatho ophezulu kwaye banike inkxaso kwithenda.

    4. Inkqubo engqongqo ye-QC: Uvavanyo olupheleleyo lokuhamba, uvavanyo olugqibeleleyo kunye nengxelo, uhlolo lwenkampani yesithathu
