Ubwino wabwino China Hot DIP Sch40 A53 API 5L Gr. B Wopanda Msokonezo / Wozungulira Wowotcherera /ERW/Malatisi a Carbon Steel Pipe
Mwachidule
Tiyesetsa aliyense payekha kuti akhale apadera komanso abwino, ndikufulumizitsa masitepe athu kuti tiyime pakati pa mabizinesi apamwamba kwambiri padziko lonse lapansi a A53 Gr. B Chitoliro Chachitsulo Chopanda Msoko / Chowotchedwa, Tikukulandirani kudzayendera fakitale yathu ndikuyembekeza kukhazikitsa ubale wabwino wabizinesi ndi makasitomala kunyumba ndi kunja posachedwa. Zogulitsa zathu zonse ndi zothetsera zimagwirizana ndi miyezo yapadziko lonse lapansi ndipo zimayamikiridwa kwambiri m'misika yosiyanasiyana padziko lonse lapansi. Ngati muli ndi chidwi ndi chilichonse mwazinthu zathu kapena mukufuna kukambirana za dongosolo, kumbukirani kuti muzitha kulumikizana nafe. Takhala tikuyembekezera kupanga ubale wabwino wamabizinesi ndi makasitomala atsopano posachedwa.
ASTM A53 imatchula zofunikira za mapaipi achitsulo opanda msoko / otsekemera akuda ndi otentha otentha kuti agwiritse ntchito. Chitsulo chotchulidwa muyeso chiyenera kukonzedwa mu ng'anjo yotseguka, mpweya wa alkaline kapena ng'anjo yamagetsi, ndipo iyenera kukhala ndi zofunikira za mankhwala: carbon, manganese, phosphorous, sulfure, mkuwa, nickel, chromium, molybdenum ndi vanadium. Chitolirocho chiyenera kukhala chopanda msoko kapena chowotcherera. Mayeso olimba, kupindika ndi kupendekeka akuyenera kuchitidwa kuti awonetsetse kuti akuyenera kukwaniritsa zomwe zimayendera pamakina. Kuyesedwa kwa hydrostatic pressure kuchitidwa, ndipo palibe kutayikira kudzera mu weld kapena thupi la chitoliro. Mayeso osawononga magetsi amayenera kuchitidwa kuti awonetsetse kuti kuchuluka kwa mapaipi ayenera kukumana ndi muyezo. Ngati zikuwoneka kuti ndizofunikira kuwonetsetsa kuti payipi ikukwaniritsa zofunikira zomwe zafotokozedwa, wogula ali ndi ufulu wochita zowunikira ndi mayeso omwe afotokozedwa mwatsatanetsatane.
ASTM A 53 ndi yoyenera kukakamiza mapaipi amagetsi, mapaipi a mapaipi ndi mapaipi ambiri pa kutentha kwa madigiri 350. Pakati pawo, kalasi yachitsulo ya Gr.B ndiyomwe imagwiritsidwa ntchito kwambiri, ndi mphamvu zake zolimba ≥ 415 (MPa) ndi zokolola mphamvu ≥ 240 (MPa).
Kugwiritsa ntchito
Amagwiritsidwa ntchito makamaka pazigawo zamphamvu ndi zokakamiza, komanso pazolinga zonse za nthunzi, madzi, gasi ndi mapaipi amlengalenga.
