Ipayipi Line Welding Spiral Seam Steel Amapayipi
KwaCangzhou Spiral Steel Pipe Group Co., Ltd.,Okwethuamapayipi e-seam e-spiralyimikhiqizo yekhwalithi ephezulu ehlangabezana namazinga aphezulu embonini.Amapayipi ethu enzelwe ukusetshenziswa okuhlukahlukene futhi aziwa ngokuhlala kwawo isikhathi eside, amandla kanye nokumelana nokugqwala.
Ikhabhoni iyisici esiyisisekelo kakhulu sensimbi futhi isisekelo sokuhlukanisa insimbi nensimbi.Amapayipi ethu e-spiral seam enziwe nge-carbon steel yekhwalithi ephezulu eqinisekisa amandla amakhulu nokuqina.Ngokuqukethwe kwawo okuphezulu kwekhabhoni, amapayipi ethu afanele uhla olubanzi lwezicelo zezimboni.

Ngaphezu kwekhabhoni, amashubhu ethu e-spiral seam aqukethe ezinye izakhi ezibalulekile njenge-nickel ne-chromium.I-Nickel iyinsimbi ye-ferromagnetic eyengeza amandla kanye nokupholisha kwepayipi.Ukwengeza, imelana nokugqwala futhi iqinisekisa impilo ende yesevisi yamapayipi ethu.I-Chromium, ngakolunye uhlangothi, iyisici esibalulekile kunsimbi engagqwali futhi inokumelana nokugqwala okuhle kakhulu.Ukufakwa kwe-chromium kumapayipi ethu othungelwano oluzungezayo kwandisa ukuphila kwawo isikhathi eside nokwethembeka.
Enye yezinzuzo eziyinhloko zamapayipi ethu e-spiral seam umklamo wawo ongenamthungo, otholakala ngobuchwepheshe bokushisela obusezingeni eliphezulu.Ubuchwepheshe bethu bokushisela besimanje be-SAWH (Submerged Arc Spiral Welding) buqinisekisa isibopho esiqinile nesihlala isikhathi eside phakathi kwamapuleti ensimbi yamapayipi.Lobu buchwepheshe be-welding abugcini nje ukukhulisa izakhiwo zemishini yepayipi, kodwa futhi kuqinisekisa indawo yangaphakathi ebushelelezi, ehambisana nokugeleza okuphumelelayo kwamanzi ahlukahlukene noma amagesi.
Amapayipi ethu asongwe asetshenziswa kakhulu ezimbonini eziningi, okuhlanganisa uwoyela negesi, ezokuthutha ngamanzi, ezokwakha kanye nokuthuthukiswa kwengqalasizinda.Ingasetshenziswa kumaphrojekthi angasogwini nasogwini nasezinhlelweni zamapayipi ngezinhloso ezahlukene.Ngokumelana nokugqwala okuhle kakhulu namandla aqinile aqinile, amapayipi ethu ayisinqumo sokuqala sokushisela amapayipi ezindaweni ezinokhahlo.

| 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. | ||||||||
Kwa-Cangzhou Spiral Steel Pipe Group Co., Ltd., sibeka izinga nokwaneliseka kwamakhasimende kuqala.Ithimba lethu elizinikele lochwepheshe liqinisekisa ukuthi ipayipi ngalinye le-spiral seam libhekana nezinqubo eziqinile zokulawula ikhwalithi ukuze lihlangabezane namazinga omhlaba.Ngaphezu kwalokho, sinikeza uhla olubanzi lwezinketho zokuhlanganisa amapayipi, okuhlanganisa i-epoxy, i-polyethylene nodaka lukasimende, ukuze kuthuthukiswe ukumelana nokugqwala kwepayipi nokwelula isikhathi sokusebenza kwalo.
Ngokufigqiwe
I-Cangzhou Spiral Steel Pipe Group Co., Ltd. iyaziqhenya ngokuhlinzeka ngamapayipi okuthunga asonga aphezulu ezinhlelo zokusebenza ezihlukahlukene.Sigxila ekukhiqizeni okunembayo, ubuchwepheshe bokushisela obusezingeni eliphezulu kanye nezinto ezisezingeni eliphezulu ukuze sinikeze amakhasimende izixazululo ezinokwethenjelwa, ezisebenzayo zezidingo zabo zamapayipi.Sithembe ukuthi sizohlangabezana nazo zonke izidingo zakho futhi uzibonele mathupha ukwethembeka nokuqina kwamapayipi ethu othungelwano oluzungezayo.
