    Iyini ipayipi lomugqa elihlanganisiwe le-arc elihlanganisiwe le-X65 spiral?

    Ipayipi lomugqa le-X65 SSAW (elifakwe ngaphansi kwe-arc welded) uhlobo lwepayipi lensimbi elisetshenziswa kabanzi e-USipayipiukwakhiwa embonini kawoyela negesi. Inhlanganisela yaleli phayiphi lomugqa yamandla, ukuqina kanye nokusebenza okumangalisayo kwenze kwaba ukukhetha kokuqala kwamaphrojekthi ahlukahlukene emhlabeni jikelele.

    Ipayipi Elihlanganisiwe Eliyi-Helical

    Amandla nokuqina:

    Esinye sezici ezibalulekile ezihlukanisa ipayipi lomugqa we-X65 spiral submited arc welded ukuqina kwalo okumangalisayo nokuqina kwalo. Lenziwe ngensimbi esezingeni eliphezulu, inokumelana okunamandla nengcindezi yangaphakathi neyangaphandle. Lokhu kuyenza ibe yisinqumo esingcono kakhulu sokusetshenziswa kukawoyela negesi okudingakalayo, okuqinisekisa ukuthi ingqalasizinda ithembekile futhi ihlala isikhathi eside.

    Ukusebenza kahle kwepayipi:

    Ukusebenza kahle kuyisici esibalulekile lapho kuthuthwa izinsiza ngamapayipi. Ipayipi lomugqa we-X65 SSAW lihamba phambili kule ndawo, lihlinzeka ngokugeleza okubushelelezi nokungqubuzana okuncane, ngaleyo ndlela linciphise ukusetshenziswa kwamandla ngesikhathi sokuthuthwa. Lokhu kusebenza kahle kusiza ukonga izindleko futhi kunciphise umthelela emvelweni, okwenza kube ukukhetha okunobungani nemvelo.

    a. Indlela yokususa i-oxidation ichazwa kanje:

    FF: Insimbi ebulewe ngokuphelele equkethe izinto zokubopha i-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isb. ubuncane be-0,020% iyonke i-Al noma i-0,015% i-Al encibilikayo).

    b. Inani eliphezulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa okuqukethwe okungenani kwe-Al okungu-0,020% kanye nesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izinto ezibophayo ze-N ezanele. Izinto ezibophayo ze-N kufanele ziqoshwe kuDokhumenti Yokuhlola.

    Imelana nezimo ezinzima:

    Amanethiwekhi amapayipi adlula ezindaweni ezahlukahlukene, kufaka phakathi izindawo ezinzima nezigqwalisayo. Ipayipi lomugqa we-X65 spiral submerged arc welded libonakalise ukuthi liphakeme ezimweni ezinjalo ngenxa yokumelana kwalo okuhle kakhulu nokugqwala, ukuklwebheka nezinye izici zangaphandle. Lokhu kumelana kuqinisekisa ubuqotho besistimu yamapayipi, kunciphisa izindleko zokulungisa, futhi kunciphisa ingozi yokuvuza noma ukwehluleka.

    I-ASD:

    Ukugcina imisebenzi yamapayipi ephephile kubalulekile. Ipayipi lomugqa we-X65 SSAW libeka phambili ukuphepha ngokuletha izakhiwo ezinhle kakhulu zemishini kanye nokunemba kobukhulu. Ngezinyathelo eziqinile zokulawula ikhwalithi, ipayipi ligcina ubuqotho besakhiwo obudingekayo ukuze libhekane nokucindezeleka okuphezulu kanye nezimo zokusebenza eziyinselele, liqinisekisa ukuphepha kwabasebenzi kanye nezinsizakusebenza.

    Ekuphetheni:

    Ipayipi lomugqa le-X65 SSAW livelele njengesixazululo esingcono kakhulu ekwakhiweni nasekugcinweni kwengqalasizinda yamapayipi. Amandla ayo, ukuqina, ukusebenza kahle kanye nokumelana nezimo ezinzima kwenza kube ukukhetha okuhle kakhulu embonini kawoyela negesi kanye nezinye izimboni ezithembele ekuthuthweni kwezinsiza kusebenza kahle. Ipayipi lomugqa le-X65 SSAW linegalelo ekongeni izindleko, ekuzinzeni kwemvelo kanye nokuqinisekiswa kokuphepha, okwenza libe yimpahla ebalulekile ekusebenzeni kwamapayipi okufuna ukuthembeka nokusebenza kahle.

    Ngakho-ke, uma uqala iphrojekthi yokufaka amapayipi, ukucabangela ipayipi lomugqa we-X65 SSAW kuyisinqumo esihlakaniphile esiqinisekisa ukusebenza okuphezulu kanye nempumelelo yesikhathi eside. Tshala imali kulesi sixazululo sekhwalithi ephezulu bese ubona umthelela oguqulayo esingaba nawo engqalasizinda yakho yamapayipi.
