I-High Quality yase-China ASME/API/GOST/DIN/En/JIS Ayinamthungo futhi Ipayipi Lensimbi Elishiselwe
Uhlolojikelele
Konke esikwenzayo kuvame ukuxhunyaniswa nemfundiso yethu ethi " Umthengi kuqala, Thembela ekuqaleni, ugxile ekupakisheni kokudla kanye nokuphepha kwemvelo ku-High Quality Seamless and Welded Steel Pipe, Sibeka ubuqotho nempilo njengomthwalo wemfanelo oyinhloko. Manje sinochwepheshe oqeqeshiwe. Ithimba lezohwebo lamazwe ngamazwe elithole iziqu eMelika Sibe ngabalingani bakho bebhizinisi elilandelayo Ngokunamathela kumgomo othi "Ukufuna Iqiniso, Ukunemba kanye Nobunye", ngobuchwepheshe njengomongo, inkampani yethu iyaqhubeka nokusungula, ezinikele ekukunikezeni. ngemikhiqizo engabizi kakhulu kanye nesevisi ecophelelayo yangemva kokuthengisa Sikholelwa ngokuqinile ukuthi: sivelele njengoba sikhethekile.
Phakathi kwezinto ezijwayelekile zamapayipi ensimbi angenamthungo, i-DIN1629 ST52 ingenye yezinto ezisetshenziswa kakhulu. Ezindinganisweni zesiShayina, ngokuvamile ihambisana ne-GB/T8162 Q345B. Zombili zingashintshwa ngomunye nomunye, kodwa azihambisani ngokuphelele. .
Mayelana nokwakheka kwamakhemikhali:
I-DIN 1629 ST52: C: 0.17%ubukhulu; P: 0.04%ubukhulu; S:: 0.04%ubukhulu; N: 0.009%ubukhulu
I-GB/T 8162 Q345B: C: 0.2%ubuningi; P: 0.035%ubukhulu; S:: 0.035%ubukhulu; N: 0.012%ubukhulu
Kuyabonakala ukuthi la mazinga amabili abeka ngokuhlanganyela ukuthi okuqukethwe yizakhi zamakhemikhali kuyefana.
Ukusebenza kukamishini:
I-DIN 1629 ST52: Amandla e-Tensile: 500~650Mpa; Amandla okukhiqiza: 335 ~ 355Mpa; Ubude (longitudinal): 21%min
I-GB/T 8162 Q345B: Amandla e-Tensile: 470~630Mpa; Amandla okukhiqiza: 295 ~ 345Mpa; Ubude (longitudinal): 20%min
Izidingo zezakhiwo zemishini zalokhu okubili nazo zicishe zifane
Izinto zokuhlola:
I-DIN 1629 idinga ukuhlolwa okuqinile, ukuhlolwa okuphansi, ukuhlolwa kokuqina, ukuhlolwa kwendawo, ukuhlolwa kobukhulu; ukuhlaziya umkhiqizo ophelile
I-GB/T8162 Q345B idinga ukuhlolwa kokwakheka kwamakhemikhali, ukuhlolwa okuqinile, ukuhlolwa kokuqina, ukuhlolwa komthelela okungu-20℃, ukuhlolwa kokucaba, ukuhlolwa kokugoba, ukuhlolwa kukagesi okungacekeli phansi
Kungabonakala ukuthi izidingo zephrojekthi yokuhlola ye-GB/T8162 Q345B ngokuyisisekelo zifaka i-DIN1629
Izidingo zokubekezelela:
I-DIN1629 ithi:
Ukubekezela kwe-OD:
OD≤100mm, ±1%noma±0.5mm
100mm<OD≤200mm, ±1%

I-GB/T8162 ibeka:
Ukubekezela kwe-OD:
±1% noma ±0.5mm kokukhudlwana
Ukubekezelelana kwe-WT:
OD≤102mm: ± 12.5% noma ± 0.4mm enkulu
OD>102mm:WT≤0.05mm, ±15% noma ±0.4mm kokukhudlwana
0.05mm<WT≤0.1mm, ±12.5% noma ±0.4mm kokukhudlwana
WT-0.1mm, +12.5% -10%
Ukubekezelelana kokubili nakho kucishe kufane
Ngakho-ke, i-Q345B ne-ST52 ingashintshwa enye nenye uma isetshenziswa endaweni evamile futhi akukho mfuneko ekhethekile. Lapho imvelo noma izidingo ziqinile, ukuqhathanisa kudinga ukucatshangelwa ngokucophelela.
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%. |
