ICarbon Structure Steel Pipe
Inkampani yethu ithumela ngaphandle imibhobho yentsimbi,Umbhobho waseTshayina ongenamthungo, Imibhobho yesakhiwo saseTshayina, umbhobho wentsimbi ongenamthungo, imibhobho yesakhiwo. Izinto ze-Q345B luhlobo lombhobho wentsimbi yesakhiwo.
I-Q345 luhlobo lwezinto zentsimbi. Yintsimbi ye-carbon alloy (c <0.2%) kunye nokusebenza kakuhle ngokubanzi, ukusebenza kakuhle kweqondo lokushisa eliphantsi, ukusebenza kwe-stamping ebandayo, ukusebenza kwe-welding kunye ne-machinability. Isetyenziswe ngokubanzi kwiibhulorho, izithuthi, iinqanawa, izakhiwo, iinqanawa zoxinzelelo, njl njl. I-Q imele isivuno sale nto, kwaye i-345 yokugqibela ibhekisela kwixabiso lemveliso yale nto, ejikeleze i-345MPa. Kwaye njengoko ubukhulu bezinto eziphathekayo bukhula, ixabiso layo lesivuno liyancipha.
Unikeze Amandla:≤16mm:ngaphezu kwe-345, 16-40mm: ngaphezu kwe-335, 40-63mm: ngaphezu kwe-325, 63-80mm: ngaphezu kwe-315, 80-100m: ngaphezu kwe-305, 100-150mm: ngaphezu kwe-285, 150-200mm: 275.

a.Ukongeza kwi-Q345A kunye ne-Q345B amabakala, intsimbi kufuneka iqulethe ubuncinane enye yezinto eziziinkozo ezicocekileyo i-Al, Nb, V, kunye ne-Ti. Ngokweemfuno, umthengisi unokongeza enye okanye ngaphezulu kwezinto eziziinkozo ezicocekileyo. Elona xabiso liphezulu liyakuba njengoko lichaziwe kwitheyibhile. Xa idibene, i-Nb + V + Ti ayikho ngaphezu kwe-0.22%b. Kwi-Q345, Q390, Q420 kunye ne-Q46O amabakala, i-Mo + Cr ayikho ngaphezu kwe-0.30%c. Xa i-Cr kunye ne-Ni yebakala ngalinye zisetyenziswa njengezinto ezishiyekileyo, umxholo we-Cr no-Ni akufanele ube mkhulu kune-0.30%; xa kuyimfuneko ukongeza, umxholo kufuneka uhlangabezane neemfuno kwitheyibhile okanye unqunywe ngumthengisi kunye nomthengi ngokubonisana.d. Ukuba umthengisi unokuqinisekisa ukuba umxholo we-nitrogen uhlangabezana neemfuno kwitheyibhile, uhlalutyo lomxholo we-nitrogen alunakwenziwa. Ukuba i-Al, i-Nb, i-V, i-Ti kunye nezinye izinto ze-alloy kunye nokulungiswa kwe-nitrogen zongezwa kwintsimbi, umxholo we-nitrogen awukhawulelwanga. Umxholo wokulungiswa kwenitrogen kufuneka ucaciswe kwisiqinisekiso somgangatho.e. Xa usebenzisa i-aluminium epheleleyo, umxholo we-aluminium opheleleyo Alt ≥ 0020%. |
