Kuvunguza ipayipi le-arc efakwe i-arc e-API 5L Line Pipe Izicelo

Incazelo emfushane:

Emkhakheni we-oyili kanye negesi, ukusetshenziswa kwamapayipi we-welded e-welded aphakathi e-spiral ahamba ngokwengeziwe, ikakhulukazi ekwakhiweni kwezinhlelo ze-API 5L Line Pipeal. I-SSAW (i-arc efakwe i-arc ye-arc) yaziwa ngamandla ayo aphezulu, ukuqina kanye nokuvumelana nezimo, okwenza kube yinto elungele ukusetshenziswa kwezicelo ezinjengomkhakha kawoyela negesi.

Le khasiI-API 5L Line PipeOkujwayelekile kungukucaciswa okwenziwe yi-American Petroleum Institute (API) yokuhamba igesi yemvelo, uwoyela namanzi. Ibonisa izidingo zokukhiqiza amapayipi ensimbi ezinama-welded futhi ibeka imihlahlandlela eqinile yekhwalithi, amandla nokusebenza kwalawa mapayipi.

Ipayipi le-SSAWKwenziwa kusetshenziswa inqubo ye-welding engaphansi ye-Arc efaka ukwakha ikhoyili yensimbi ibe ngesimo esiyindilinga bese usebenzisa i-arc ye-welding ukuze ufake imiphetho yekhoyili ndawonye.

Enye yezinzuzo eziphambili zokusebenzisa ipayipi elifakwe endaweni ephakathi nendawo e-API 5L Line Pipe Izicelo zekhono labo lokubekezelela amazinga aphezulu okucindezela kwangaphakathi. Lokhu kubaluleke kakhulu embonini kawoyela negesi, lapho amapayipi evezwa khona ezimweni ezinzima nemithwalo esindayo. Ukwakhiwa okunamandla kwamapayipi e-SSAW kwenza kube kuhle kumapayipi asebenza ekucindezelweni okuphezulu namazinga okushisa, ukuhlinzeka ngesisombululo esithembekile nehlala isikhathi eside sokuhamba kwezinto zokuhamba ezibalulekile.

Ngaphezu kwalokho, ukuguquguquka kwepayipi elisezingeni eliphansi le-arcy eliphakathi nendawo kwenza kube lula ukufaka nokugcina, okwenza kube ukukhetha okungabizi kakhulu kwamaphrojekthi wokwakha amapayipi. Amandla abo okushintsha futhi avumelane nemidwebo yemvelo yendawo eqeda isidingo sokukhiqiza abiza kakhulu futhi anciphise ngesikhathi sokukhiqiza futhi anciphise ubungozi bokuvuza nokwehluleka. Ngokwengeziwe, indawo ebushelelezi yangaphakathi yamapayipi we-SSAW inciphisa ukungezwani kanye nesiphithiphithi, okuholela ekuhambeni kahle kokugeleza kanye nokusetshenziswa kwamandla okuphansi.

Inani eliphakeme le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kukhombisa okuqukethwe okuphelele kwe-AL ye-AL ye-0,020% ngesilinganiso esingu-2: 1, noma uma kungenjalo ezinye izinto ezibophayo ze-N zikhona. Izinto ezibophayo ze-N-Bonding zizoqoshwa kudokhumenti lokuhlola.

Ngamafuphi, ukusetshenziswa kwepayipi eliphakathi nendawo eliphakathi kwe-arl Amandla abo, ukuqina kanye nokuqina kwezimo eziguquguqukayo kubenza bakwazi ukusetshenziswa ezindaweni ezifunwayo, kanti ukukhululwa kwabo kokufakwa nezidingo zokulungiswa okuphansi kunikeza isixazululo esisebenza ngempumelelo yamaphrojekthi wokwakha amapayipi. Njengokufunwa kwempahla ethembekile, esebenza kahle yamafutha, igesi yemvelo namanzi kuyaqhubeka ukukhula, ukubaluleka kwepayipi elifakwe emgodini we-arc ephakathi nendawo emoneni we-API 5L Line Piple Standard alikwazi ukweqiwa. Ngokusebenza kwayo okufakazelwe nokuguquguquka,Kuvunguza i-arc efakwe emgodiniisethwe ukuqhubeka nokuba yingxenye ebucayi yengqalasizinda eshayela umnotho wembulunga yonke.
