    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Inkampani yethu ithumela kwamanye amazwe amapayipi ensimbi,China Seamless Pipe, Amapayipi esakhiwo saseShayina, ipayipi lensimbi engenamthungo, amapayipi esakhiwo. I-Q345B impahla iwuhlobo lwepayipi lensimbi yesakhiwo.

    I-Q345 iwuhlobo lwensimbi. Kuyinsimbi ye-carbon alloy (c<0.2%) esebenza kahle kukonke, ukusebenza kahle kwezinga lokushisa eliphansi, ukusebenza kwesitembu esibandayo, ukusebenza kwe-welding kanye nokusebenza kahle. Isetshenziswa kabanzi kumabhuloho, ezimotweni, emikhunjini, ezakhiweni, emikhunjini yokucindezela, njll. U-Q umele isivuno salokhu kwaziswa, kanti i-345 yokugcina ibhekisela enanini lokukhiqiza lale nto, ezungeze i-345MPa. Futhi njengoba ukushuba kwezinto kukhula, inani layo lokukhiqiza liyehla.

    Q345 Q345

    Amandla okukhiqiza:≤16mm:ngaphezu kuka-345, 16-40mm: ngaphezu kuka-335, 40-63mm:ngaphezu kuka-325, 63-80mm: ngaphezu kuka-315, 80-100m: ngaphezu kuka-305, 100-150mm: ngaphezu kuka-285, 150-200mm: ngaphezu 275.

    Amandla okuqina: 450-630.

    Ubude: ngaphezu kwe-17.

    Ukuhlolwa komthelela: Izinga lokushisa lokuhlola: 20°C: ezingaphezu kuka-34.

    a.Ngokungeziwe kumamaki e-Q345A ne-Q345B, insimbi kufanele iqukathe okungenani okukodwa kwezakhi zokusanhlamvu ezicwengisisiwe i-Al, Nb, V, ne-Ti. Ngokwezidingo, umphakeli angakwazi ukwengeza izakhi zokusanhlamvu ezicwengisisiwe eyodwa noma ngaphezulu. Inani eliphakeme lizoba njengoba lishiwo kuthebula. Uma ihlanganiswa, i-Nb + V + Ti ayikho ngaphezu kuka-0.22%b. Kumabanga e-Q345, Q390, Q420 kanye ne-Q46O, i-Mo + Cr ayikho ngaphezu kuka-0.30%c. Uma i-Cr ne-Ni yebanga ngalinye kusetshenziswa njengezakhi ezisele, okuqukethwe kwe-Cr ne-Ni akufanele kube kukhulu kuno-0.30%; uma kudingekile ukwengeza, okuqukethwe kufanele kuhlangabezane nezidingo etafuleni noma kunqunywe umphakeli nomthengi ngokubonisana.d. Uma umphakeli engaqinisekisa ukuthi okuqukethwe yi-nitrogen kuyahlangabezana nezimfuneko ezisethebula, ukuhlaziywa kokuqukethwe kwe-nitrogen kungase kungenziwa. Uma i-Al, Nb, V, Ti nezinye izakhi ze-alloy ezine-nitrogen fixation zengezwa ensimbi, okuqukethwe kwe-nitrogen akunqunyelwe. Okuqukethwe kokulungisa i-nitrogen kufanele kucaciswe kusitifiketi sekhwalithi.e. Uma usebenzisa i-aluminium egcwele, ingqikithi yokuqukethwe kwe-aluminium Alt ≥ 0020%.
