Ukuqonda i-ASTM A139: Umgogodla We-SAWH Pipe kanye Nezicelo Zepayipi Elihlanganisiwe Elijikelezayo

Ezweni lamapayipi ezimboni, amakhodi nezindinganiso ezilawula izinto ezisetshenziswayo zibalulekile ekuqinisekiseni ukuphepha, ukuqina kanye nokusebenza kahle. Enye yalezi zindinganiso yileI-ASTM A139, edlala indima ebalulekile ekukhiqizweni nasekusetshenzisweni kwamapayipi e-SAWH (spiral arc welded hollow) kanye namapayipi e-spiral welded. Kule bhulogi, sizoxoxa ngokubaluleka kwe-ASTM A139, izici zepayipi le-SAWH, kanye nezinzuzo zePipe Ehlanganisiwe Ye-Helical ezimbonini ezahlukahlukene.

Kuyini i-ASTM A139?

I-ASTM A139 iyincazelo ethuthukiswe yi-American Society for Testing and Materials (ASTM) echaza izidingo zepayipi lensimbi elihlanganisiwe nge-electrofusion (arc). Leli zinga lisebenza ikakhulukazi kumapayipi asetshenziselwa ukuthutha uketshezi namagesi. Imininingwane ihlanganisa ububanzi bezinhlobo zensimbi futhi iqinisekisa ukuthi amapayipi akhiqizwayo ahlangabezana nezakhiwo ezithile zemishini kanye nokwakheka kwamakhemikhali.

Izinga le-ASTM A139 libalulekile kubakhiqizi nakonjiniyela ngoba linikeza isiqondiso ngenqubo yokukhiqiza, okuhlanganisa amasu okushisela kanye nezinyathelo zokulawula ikhwalithi okumele zithathwe. Ngokunamathela kulezi zindinganiso, abakhiqizi bangaqinisekisa ukuthi imikhiqizo yabo ithembekile futhi ifanele ukusetshenziswa okuhlukahlukene, kusukela ekuthuthweni kukawoyela negesi kuya ekusetshenzisweni kwesakhiwo.

Indima yombhobho we-SAWH

Ipayipi le-SAWH noma ipayipi elingenalutho elihlanganisiwe eliyi-spiral arc liwuhlobo lwepayipi elihlanganisiwe elenziwe ngokuhlanganisa imichilo yensimbi eyisicaba ibe yisimo esiyindilinga. Le ndlela yokukhiqiza ivumela ukudalwa kwamapayipi amakhulu aqinile futhi alula. Ubuchwepheshe bokuhlanganisa obusetshenziswa kuAmapayipi e-SAWH inikeza izinzuzo eziningana, okuhlanganisa:

1. Ukusebenza Kahle Kwezindleko:Inqubo yokukhiqiza amapayipi e-SAWH ivame ukonga kakhulu kunezindlela zendabuko, okwenza kube inketho ekhangayo kumaphrojekthi amakhulu.

2. UKUSEBENZISA IZINTO EZININGI:Ipayipi le-SAWH lingakhiqizwa ngobukhulu nobukhulu obuhlukahlukene, okwenza lifaneleke ezindaweni eziningi zokusebenza, okuhlanganisa izinsiza zamanzi, izinhlelo zamanzi angcolile, kanye nezingxenye zesakhiwo.

3. Amandla Athuthukisiwe:Ukwakhiwa okuhlanganisiwe okujikelezayo kunikeza amandla engeziwe kanye nokumelana nengcindezi yangaphandle, okwenza ipayipi le-SAWH lifaneleke kakhulu ezindaweni ezicindezelayo.

Izinzuzo zepayipi elihlanganisiwe eliyindilinga

Ipayipi elihlanganisiwe elijikelezayo lingenye indlela yepayipi elihlanganisiwe elenziwa kusetshenziswa ubuchwepheshe bokushisela okujikelezayo. Le ndlela ihilela ukugoqa umucu wensimbi uzungeze i-mandrel bese uyishisela ngendlela ejikelezayo eqhubekayo.Ipayipi Elihlanganisiwe Eliyi-Helical inikeza izinzuzo eziningana, okuhlanganisa:

1. Izici zokugeleza ezithuthukisiwe:Ubuso obubushelelezi bangaphakathi be-Helical Welded Pipe bunciphisa ukuxokozela futhi buthuthukisa ukugeleza koketshezi, okwenza kube kuhle kakhulu ekusetshenzisweni kwemboni kawoyela negesi.

2. ISINDI ESINCIPHISIWE:Umklamo ojikelezayo uvumela izindonga ezincane ngaphandle kokwehlisa amandla, okwenza ipayipi libe lula futhi kube lula ukuyiphatha nokuyithutha.

3. Ubude Obungenziwa Ngokwezifiso:Ipayipi Elihlanganisiwe Eliyi-Helical lingakhiqizwa ngobude obude, kunciphisa inani lamajoyinti adingekayo epayipini futhi kuncishiswe amathuba okuvuza.

Ekuphetheni

Ngamafuphi, i-ASTM A139 iyindinganiso eyinhloko yokukhiqizwa kwepayipi le-SAWH kanye nepayipi elihlanganisiwe elihlanganisiwe, okuqinisekisa ukuthi lezi zingxenye ezibalulekile zihlangabezana nezindinganiso zokuphepha nokusebenza ezidingekayo. Izakhiwo ezihlukile zepayipi elihlanganisiwe le-SAWH kanye nepayipi elihlanganisiwe elihlanganisiwe zizenza zibe usizo kakhulu ezimbonini ezisukela ekwakheni kuya emandleni. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ukubaluleka kokunamathela ezindinganisweni ezimisiwe njenge-ASTM A139 kuzokhula kuphela ukuqinisekisa ukuthi ingqalasizinda esithembele kuyo ihlala iphephile futhi isebenza kahle. Kungakhathaliseki ukuthi ungunjiniyela, usonkontileka, noma umphathi wephrojekthi, ukuqonda lezi zindinganiso kanye nezinzuzo zalezi zinhlobo zamapayipi kubalulekile ekwenzeni izinqumo ezinolwazi ngamaphrojekthi akho.
