Intengo esaphulelo yase-China Low-Alloy Steel (Machanical and Hydraulic) Pipe
Uhlolojikelele
Ngaso sonke isikhathi kuthambekele kumakhasimende, futhi kuwumgomo wethu omkhulu ukuthola hhayi kuphela umphakeli onedumela elihle, onokwethenjelwa nothembekile, kodwa futhi nozakwethu wamakhasimende ethu we-Low-Alloy Steel (Machanical and Hydraulic) Pipe, Siyakwamukela ukuthumela isampula yakho futhi indandatho yombala ukuze usivumele sikhiqize ngokusho kwakho.Siyakwamukela uphenyo lwakho! Sibheke phambili ekwakheni ukubambisana kwesikhathi eside nawe! Inkampani yethu isekela umoya "wokusungula izinto ezintsha, ukuvumelana, ukusebenza kweqembu nokwabelana, imikhondo, inqubekelaphambili ye-pragmatic". Sinikeze ithuba futhi sizofakazela ikhono lethu. Ngosizo lwakho lomusa, sikholwa ukuthi singakha ikusasa eliqhakazile nawe sindawonye.
I-TS EN 10216-1 P235 yinto ejwayelekile yepayipi lensimbi. Ngokwezinga, ihlukaniswe ngamabanga amabili: TR1 kanye ne-TR2. I-TR1 ayidingi ukwelashwa ngokushisa, kuyilapho i-TR2 idinga ukwelashwa okujwayelekile. I-TR2 icishe ilingane ne-TR2 ngokokwakheka kwamakhemikhali, kodwa idinga izakhi ezengeziwe; I-TR1 kanye ne-TR2 cishe zilingana ngokwezakhiwo zemishini. Umehluko ukuthi i-TR1 ayidingi ukuhlolwa komthelela, kuyilapho i-TR2 idinga ukuhlolwa komthelela okungu-0°C. Izidingo zokuhlola amapayipi aqediwe nazo zihlukile ku-TR1 ne-TR2. I-TR1 idinga kuphela ukuhlolwa okujwayelekile, kuyilapho i-TR2 idinga ukuhlolwa okukhethekile (ukuhlolwa komthelela okwengeziwe).
Uma kungekho sidingo esikhethekile, i-EN10216 P235 TR1 iyona esetshenziswa kakhulu, efana ne-Chinese steel grade GB/T8163 20# noma i-GB/t8162 Q235C, futhi ingashintshwa enye nenye.
Isicelo
Isetshenziswa Ikakhulukazi Ukwenza Insimbi Yesakhiwo Sekhabhoni, Insimbi Yokwakheka Kwengxubevange kanye nezakhiwo zemishini.

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%. |

Esivivinyweni sokuqina, amasampula aguquguqukayo noma amalongi angathathwa. Esimeni sokungavumelani, isampula ye-longitudinal isetshenziswa njengesisekelo sokulamula.c. Insimbi equkethe i-boron ingenziwa ibe yijwayelekile ngaphambi kokucisha, futhi izinga lokushisa elivamile akufanele libe ngaphezu kwezinga layo lokushisa lokucisha.d. Ukulethwa ngokuya ngeqoqo ledatha elicaciswe umfakisicelo. Lapho lowo odingayo engakacacisi, ukulethwa kungenziwa ngokuya nganoma iyiphi idatha. e. Ukucinywa kokuqala kwensimbi ye-titanium nge-Ming Meng kungathathelwa indawo ngokujwayelekile. f. I-Isothermal quenching ku-280 C ~320 C. g. Esivivinyweni sokuqina, uma i-Rel ingenakulinganiswa, i-Rp0.2 ingalinganiswa esikhundleni se-Rel. |
