Nthowa zakugwiriskira ncito chitoliro ca cisulo: Kufuma ku nyanja kuya ku malo ghakuthilira

Nthowa zakugwiriskira ncito - Chitoliro ca Octal

Kufuma pa viŵiya vya maji ghakunyang’amira kufikira ku mapaipi gha Arctic, ma gridi gha maji gha mu misumba yikuru kufikira ku mizere ya vimiti vya mu mapopa, malo ghakuru ghakulimapo kufikira ku malo ghakujumpha mu nkhalango za vula - Octal Pipe yikupereka msana wa chisulo chapachanya- cha nkhongono za pa charu chose, maji na vyakumangamanga.

Tumirani mafumbo sono

Mapulatifomu gha mafuta na gasi

Ma rigs gha maji ghakunyang’amira, FPSO topsides na ma jekete ghakukhazikika ghakukhumba mapaipi agho ghakupona pa nyengo zose gha mafunde, kupopera mchere na kufinyikizgika kuluska 15,000 psi. Large - diameter LSAW X65-X70 na 3LPE panji FBE + simenti kulemera kwakuvwara ndiyo muyezo wa mafakitale pano. Kulumikizana kwapachanya (VAM TOP, TENARIS BLUE) kukuwoneseska kuti gasi-kugwira ntchito mwakukhora mu mizere ya riser na kuguliska kufuma ku Nyanja ya Kumpoto ku Brazil pambere -minda ya mchere yindafike.

Mizere yakuyenda pasi pa nyanja & Tie-Msana

Pa kuzama kwakujumpha 2,500 m, SSAW X60–X70 na 5-layer sintered epoxy panji kuteteza kwakunyeŵa kukupereka mtengo uwemi chomene, kusinthasintha na kuvikilira ku dzimbiri. Helical msoko design kugaŵira kukhota kusuzgika mwakuyana pa nyengo ya reel -lay panji J -lay kuŵika, apo CWC thicknesses ya 50-120 mm yikukhozgera pa-pansi kukhazikika mu mafunde yankhongono.

Kutumizga kwa mtunda utali pa nyanja-

Mizere ya mafuta ghambura kupangika, vyakupangika na vyachilengiwa-mizere ya gasi yikuthemba pa API 5L X52–X80 LSAW kuti yifike pa makilomita ghanandi na masiteshoni ghachoko waka gha mapampu. 3 LPP coating na chitetezo cha cathodic vikupereka 50+ chaka cha umoyo wakupangika mu mapopa, permafrost na malo ghakulimapo. Kuzizipizga kwa OD kwakukhora na magulu ghakupanga vipambi vyapachanya-kusunga msinkhu wa mtenje - ndipo ntheura kulemera na mtengo - viŵe vichoko.

Kujumpha kwa Dambo, Marsh & Nkhalango

Nthaka yakufewa, yakusunkhunyika chomene mu vigaŵa nga ni Amazon Basin, Niger Delta, na Louisiana bayous yikukhumba kuŵika simenti yakulemera chomene (CWC) pa mapaipi gha SSAW panji LSAW kuti yiŵe na nkhongono ziheni na kuvikilira kusefukira kwa maji pa nyengo ya kusefukira kwa maji. Makhoma ghakukhora chomene pamoza na fusion-bonded epoxy (FBE) panji 3LPE coatings ghakulimbana na H2S, CO2, na asidi wa vinyama uyo wakusangika mu malo ghakunyeŵa.

Maji na vyakusefukira vya mu misumba

Pansi pa misewu ya msumba, .AWWA C200 mapaipi ghakuzungulirandipoMapaipi gha ASTM A53 ERWndiwo ŵakusankha chomene pa maji ghakumwa, mphete zakuvikilira moto, na maji ghakufipirwa gha nkhongono.

Vyamukatisimenti-kuŵikamo matopeolovyakurya-vyakuvwara vya epoxywakulondezga chomeneNSF/ANSI 61kwa maji ghakumwa-ghakuvikilirika, apo gha kuwaropoliyurethani, polyethylene yakufumiskika, oloTepi yakulimbana na dzimbirilikupereka chitetezo cha nyengo yitali-ku dongo la mu matawuni ilo lili na nkhaza chomene, maji gha pasi pa charu, na kuvunda kwa sono uko kukusangika mu misumba yikuruyikuru.

Kuthilira kwa mizi na kwa ulimi

Nthowa zikuru zapakati -pivot na drip zikugwiriskira ncito SSAW yakupangika na galvanized panji polyethylene- (12–48 in) kuti zisunthire malita mamiliyoni ghanandi zuŵa lililose kwambura kudontha pafupifupi zero. Kuŵa wakupepuka pa mita na utali wa 12–18 m kukuchepeska viŵaro na nyengo yakuŵikamo pa malo ghakulima ghakujulika.
