Amapayipi Akhiwe Abandayo, EN10219 S235JRH, S235J0H, S355JRH, S355J0H

Incazelo emfushane:

Le ngxenye yaleli Zinga LaseYurophu icacisa izimo zobuchwepheshe zokulethwa kwesakhiwo esishiselwe ngendlela ebandayo, izingxenye ezingenalutho zamafomu ayindilinga, ayisikwele noma angunxande futhi isebenza ezingxenyeni ezingenalutho ezakhiwe ezibandayo ngaphandle kokwelashwa okushisayo okulandelayo.

I-Cangzhou Spiral Steel Pipes Group Co., Ltd ihlinzeka ngengxenye engenalutho yamafomu ayindilinga amapayipi ensimbi okwakhiwa.

a.Indlela ye-deoxidation ikhethwe kanje:

FF: Insimbi ebulawe ngokuphelele equkethe izakhi zokubopha i-nitrogen ngamanani anele ukuhlanganisa i-nitrogen etholakalayo (isb. min. 0,020 % isiyonke i-Al noma i-0,015 % e-soluble Al).

b.Inani eliphakeme kakhulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa inani elincane eliphelele lokuqukethwe kwe-Al elingu-0,020 % elinesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izakhi ezanele zokubopha i-N.Izinto ezibophezela i-N zizorekhodwa kuMqulu Wokuhlola.

Ukuhlolwa kwe-Hydrostatic

Ubude bepayipi ngalinye kufanele buhlolwe ngumenzi kumfutho we-hydrostatic ozokhiqiza odongeni lwamapayipi ingcindezi engekho ngaphansi kuka-60% wamandla esivuno amancane ashiwo ekamelweni lokushisa.Ingcindezi izonqunywa yi-equation elandelayo:
P=2St/D

Ukwehluka Okuvumelekile Kwesisindo Nobukhulu

Ubude bepayipi ngalinye buzokalwa ngokwehlukana futhi isisindo salo angeke sihluke ngaphezu kuka-10% ngaphezulu noma u-5.5% ngaphansi kwesisindo salo esicatshangelwayo, kubalwe kusetshenziswa ubude balo nesisindo salo ngobude beyunithi ngayinye.
Idayamitha yangaphandle akumele ihluke ngaphezu kuka-±1% ukusuka kububanzi obukhethekile obushiwo bangaphandle
Ukujiya kodonga kunoma iyiphi indawo akufanele kube ngaphezu kuka-12.5% ​​ngaphansi kogqinsi olushiwo
