Ukubaluleka kwe-Piperal Arc Pipe kwi-API 5l umgca we-piebon yombhobho
Ukusetyenziswa kwe-welbon ye-carbon ye-carbon, ngakumbi i-PIREAL SPIP ye-PIC ye-PARED ye-ARC, ibaluleke kakhulu ekuqinisekiseni ingqibelelo kunye nokuthembeka kweI-API 5l yombhobho. Le ndlela ye-Welding idala umanyano olungenamthungo nohlala luhleli phakathi kwe-tubes zecarbon, ekufuneka inyanzeliswe ukumelana noxinzelelo oluphezulu kunye neemeko ezikhoyo zokusingqongileyo.
Iityhubhu ezingama-ARC ezingeneyo ze-ARC zenziwa ngenkqubo ekhethekileyo yeWolding apho i-welding arc ingene ngaphakathi kwengubo yengubo. Oku kudala i-Wieds engenamthungo, ekumgangatho okuphezulu kunye kwaye kwandisa ubude bombhobho. Ukusetyenziswa kwale ndlela ye-Welbon Parbon Pipe I-Peling ye-API 5l yombhobho uqinisekisa ukuba uqhagamshelo olunamandla nolingane oluhlangabezana neemfuno zeshishini leoyile negesi.

Ukongeza kumgangatho we-welding, umbhobho we-SSAW uneengenelo ezininzi ezenza ukuba ibe licandelo elibalulekileyo kwi-API 5l ye-5l yomgca. Uyilo lweSpiral lwePipeline lubonelela ngokuguquguquka okukhulu kunye nokungahambi kakuhle, kokwenza kube lula ukuhambisa iitarayina ezahlukeneyo kunye nemiqobo ngexesha lokwakhiwa kwepayipi.
Ukongeza, iityhubhu ze-ARC ezingena nzulu ze-ARC ziyakwazi ukuhlalisa iidayamitha ezinkulu, zenze ukuba zilungele ukuthutha imiqulu emikhulu yeoyile kunye negesi. Ukwazi kwayo ukuphatha imiqulu emikhulu yolwelo ngelixa ugcina ingqibelelo yesakhiwo ikwenza ukhetho oluthembekileyo kwimibhobho ye-API 5 yendlela.
Olunye uncedo lweetyhubhu ze-ARC ezibekwe yi-ARC luyindleko zazo. Inkqubo efanelekileyo ye-Welding kunye nokukwazi ukuvelisa imibhobho yedayitha yezinto ezinkulu zenza isisombululo esineendleko zokwakha ipleyiti. Oku kubaluleke kakhulu kwishishini leoyile negesi, apho ukwakhiwa kwe-pipeline kunye nesondlo kunokuba yindleko ezibalulekileyo.
Ukusetyenziswa kwe-SPIRAL i-Arc Armed Peped imibhobho ye-Wel ye-API kwi-API 5l yombhobho we-pie ye-pipe ibalulekile ekuqinisekiseni ingqibelelo yokuqinisekisa ukuthembeka kunye nokuthembeka kombhobho. Eyona nto iphambili kuyo i-welding, ukuguquguquka kunye nokusebenza ngendleko kwenza ukuba ibe yinxalenye ebalulekileyo ye-oyile kunye negesi yegesi.
Kwisishwankathelo, umbhobho we-SSAW udlala indima ebalulekileyo kwimibhobho ye-carbon pumela i-API 5l imibhobho yombhobho wemigca. Eyona nto iphambili kumgangatho ophezulu we-welding, bhetyebhetye kunye nokusebenza kwendleko kuyenza ilungele ukwakhiwa kwemibhobho kwishishini leoyile negesi. Ngokukhetha umbhobho we-SSAW, inkampani inokuqinisekisa ukuthembeka kunye nokuthembeka kombhobho we-API 5 ye-API 5 ye-5l, ekugqibeleni ibangelwa yinkqubo efanelekileyo yokufakelwa ngokufezekileyo.
