I-SSAW PIPyenziwa kusetyenziswa inkqubo ye-Arc ye-Arc ebandakanya ukwenza i-coil yentsimbi ibe yintsimbi yomjikelo kwaye isebenzise i-arc ye-welc ukuze isuse imiphetho ye-COC.
Esona sibonelelo siphambili sokusebenzisa umbhobho we-spiral of i-Piped Deped kwi-API 5l izicelo zobhobho ye-PIP kukukwazi kwabo ukumelana namanqanaba aphezulu kunye noxinzelelo lwangaphandle. Oku kubaluleke kakhulu kwishishini leoyile negesi, apho imipu ivezwa kwiimeko ezigqithisileyo kunye nemithwalo enzima. Ukwakhiwa kwemibhobho ye-SSAW kwenza ukuba ilungele imibhobho esebenza kwiingcinezelo eziphezulu kunye namaqondo obushushu, ukubonelela ngesisombululo esithembekileyo nesingapheliyo sothutho lwezixhobo ezixabisekileyo.
Ukongeza, ukuguquguquka kwe-Piperal Arc Proped Peped Deped yenza ukuba kube lula ukufaka nokugcina, kukwenza ukhetho olusebenzayo lweeprojekthi zokwakha. Amandla abo okuguqula kwaye avumelane neengcaciso zendalo zendawo eshenxisa imfuno yemveliso ebiza kakhulu nexesha elisebenzisayo kwaye inciphisa umngcipheko wokuvuza nokungaphumeleli. Ukongeza, umphezulu wangaphakathi wemibhobho ye-SSAW ukunciphisa ukuxabana kunye nesiphithiphithi, kukhokelela ekuhambeni okusebenzayo kunye nokusetyenziswa kwamandla asezantsi.

| a. Indlela ye-Deaxotion ichongwe ngolu hlobo lulandelayo: I-FF: Intsimbi egcinwe ngokupheleleyo i-nitrogen ebophelelayo kwizixa ezaneleyo zokubopha initrogen (umz. I-0,020% ye-al). b. Elona xabiso liphezulu le-nitrogen alisebenzi ukuba ukubekwa kwekhemikhali kubonisa i-0,020% ye-al / n i-2: 1, okanye ukuba izinto ezaneleyo ze-N-Bing zikhona. Izinto ezibophelelayo ziya kurekhodwa kuxwebhu lovavanyo. | ||||||||
Kwisishwankathelo, ukusetyenziswa kwe-Picral Arc Armmed Piped Peped I-Arc Deped Peped kwi-API 5l Ii-pie ze-Pll zibonelela ngochungechunge lwezibonelelo ezenza ukuba ibe yinto enomdla kwishishini leoyile negesi. Amandla abo, ukuqina kunye nokuguquguquka kubenze balungele ukusetyenziswa kwiindawo ezifuna ukutya, ngelixa kusenziwa lula kufakelo kunye neemfuno zolondolozo olusezantsi ukubonelela ngesisombululo esineendleko zeeprojekthi zePipeline. Njengoko imfuno yokuhamba nge-oyile ethembekileyo, esebenzayo yeoyile, igesi yendalo kunye namanzi iyaqhubeka ukukhula, ukubaluleka kwe-Picral Arc i-Arc Proped Pide kumgangatho we-API ye-API awunakuba ngaphezulu. Ngomsebenzi wayo oqinisekisiweyo,I-SPIRAL ye-ARCisetwe ukuze uqhubeke njengenxalenye ebalulekileyo yeziseko zophuhliso eziqhuba uqoqosho lwehlabathi.
