Litaba - Chaena le Russia li saenetse tumellano bakeng sa Phaephe ea khase ea tlhaho ea Siberia-2. Royal Steel Group e bontšitse boikemisetso ba eona ba ho tšehetsa nts'etsopele ea naha ka botlalo.

Ka September, Chaena le Russia li ile tsa saena tumellano bakeng sa phaephe ea khase ea tlhaho ea Siberia-2. Phaephe ena, e tla ahuoa ho pholletsa le Mongolia, e ikemiselitse ho fana ka khase ea tlhaho ho tloha libakeng tsa Russia tse ka bophirimela ho ea Chaena. Ka matla a phetisetso a selemo le selemo a li-cubic metres tse limilione tse likete tse 50, ho lebelletsoe hore e tla sebetsa ho pota 2030.

Matla a Siberia-2 ha a felle feela ka lipeipi tsa matla; ke leano la leano la ho hlophisa bocha taolo ea lefats'e. E nyenyefatsa matla a Bophirima a matla, e tebisa tšebelisano ea maano lipakeng tsa China le Russia, hape e matlafatsa matla a moruo a tikoloho. E boetse e fana ka mohlala o sebetsang oa tšebelisano-'moho lefatšeng le nang le lipolanete tse ngata. Leha e tobane le liqholotso tse ngata tsa tekheniki, tsa lipolotiki le tsa tikoloho, boleng ba leano la morero bo feta meeli ea khoebo, e leng morero oa bohlokoahali oa ho khothaletsa kaho ea sechaba se nang le bokamoso bo arolelanoeng ba batho. Joalokaha Putin a boletse moketeng oa ho saena, "Peipi ena e tla kopanya bokamoso ba rona."

Joaloka k'hamphani ea khoebo ea kantle ho naha e sebetsanang le lipeipi tsa oli le tšepe e khethehileng, Royal Steel Group e kenelletse ka botebo morerong oa lipeipi tsa khase ea "Power of Siberia 2", ha e ntse e ts'ehetsa tšebelisano ea matla le maano a nts'etsopele ea libaka lipakeng tsa China, Russia le Mongolia.

Liphaephe tse tharo tse ntšo tse cheselitsoeng ka bophara bo boholo

Royal Steel Group e ka fana ka API 5L X80, API 5L X90, le lipeipi tsa tšepe tsa 3PE.

X80 tšepe ke letšoao bakeng sa tšepe ea lipeipi tse matla haholo, e tsamaellanang le API 5L 47th edition standard. E fana ka matla a bonyane a tlhahiso ea 552 MPa, matla a ho tsitsa a 621-827 MPa, le karolelano ea lihlahisoa ho ea ho matla a 0.85 kapa ka tlase. Melemo ea eona ea mantlha e ho moralo o bobebe, ho tiea ho hoholo, le ts'ebetso e ntlafalitsoeng ea weldability.

Lisebelisoa tse tloaelehileng li kenyelletsa:
Phaephe ea Khase ea Tlhaho ea China-Russia East Line: E sebelisa tšepe ea X80 ho pholletsa le eona, e fetisetsa li-cubic metres tse limilione tse likete tse 38 tsa khase selemo le selemo le ho haola le serame sa permafrost le libaka tse nang le litšisinyeho tsa lefatše, ho beha tekanyo ea lefats'e bakeng sa theknoloji ea kaho ea lipeipi tsa lebopong.

Morero oa III oa Phaephe ea Khase ea Bophirimela-Bochabela: Lipeipi tsa tšepe tsa X80 li nka karolo e fetang 80% ea tšebeliso eohle, e tšehetsang ho tsamaisoa hantle ha khase ea tlhaho ho tloha ka bophirimela ho China ho ea sebakeng sa Yangtze River Delta.
Ho ntlafatsoa ha oli le khase metsing a tebileng: Morerong oa sebaka sa khase oa Liwan 3-1 Leoatleng la China Boroa, liphaephe tsa tšepe tse se nang seam X80 li sebelisoa bakeng sa liphaephe tse tsamaeang ka tlas'a metsi botebong ba limithara tse fetang 1,500, tse nang le matla a kantle a 35 MPa.

X90 tšepe e emela moloko oa boraro oa lipeipi tsa matla a phahameng, tse lumellanang le API 5L 47th edition standard. E na le matla a fokolang a tlhahiso ea 621 MPa, matla a 758-931 MPa, le k'habone e lekanang (Ceq) ea 0.47% kapa ka tlase. Melemo ea eona ea mantlha e kenyelletsa mehloli e phahameng ea matla, katleho ea weldability, le maemo a tlase a mocheso.

Linyeoe tse tloaelehileng tsa kopo li kenyelletsa:

Matla a Siberia 2 Pipeline: E le thepa ea mantlha ea morero, pipe ea tšepe ea X90 e tla tsamaisa khase ea sebaka se selelele ho tloha libakeng tsa khase tsa Russia Bophirimela ho ea Chaena Leboea. Ha e qala ho sebetsa ka 2030, palo ea phetiso ea khase ea selemo le selemo e lebelletsoe ho ikarabella ho feta 20% ea kakaretso ea khase ea China e tsoang kantle ho naha.

Central Asia Natural Gas Pipeline Line D: Libakeng tsa mobu o nang le letsoai haholo karolong ea Uzbek, pipe ea tšepe ea X90, e kopantsoeng le tsamaiso ea 3PE + ea ts'ireletso ea cathodic, e na le nako ea tšebeletso e atolositsoeng ho fihlela lilemo tse 50.

Thepa ea 3PE e na le "epoxy powder coating" (FBE) primer, sekhomaretsi se bohareng, le topcoat ea polyethylene (PE), e nang le botenya bohle ba ≥2.8mm, e etsang "sistimi e thata + e tenyetsehang" e kopantsoeng ea ts'ireletso:

Setsi sa motheo sa FBE, se nang le botenya ba 60-100μm, lik'hemik'hale li tlamahane le holim'a phala ea tšepe, tse fanang ka ho khomarela hantle (≥5MPa) le khanyetso ea cathodic disbondment (peel radius ≤8mm ho 65 ° C / 48h).

Sekhomaretsi sa Mahareng: 200-400μm e teteaneng, e entsoeng ka resin ea EVA e fetotsoeng, e kopantsoe le FBE le PE, ka matla a peel a ≥50N / cm ho thibela ho arohana ha interlayer.
Outer PE: ≥2.5mm e teteaneng, e entsoeng ka polyethylene e phahameng haholo (HDPE), e nang le Vicat softening point ≥110 ° C le UV e hanyetsang botsofali e pakoang ke tlhahlobo ea lebone la xenon arc ea lihora tse 336 (ho boloka matla a tensile ≥80%). E loketse ho sebelisoa libakeng tsa joang tsa Mongolia le tikolohong ea permafrost.

Royal Steel Group, ka morero oa eona oa "Material Innovation Driving the Energy Revolution," e ntse e tsoela pele ho fana ka lihlahisoa tsa lipeipi tsa tšepe tse sebetsang hantle, tse tšepahalang haholo le lits'ebeletso tsa tekheniki bakeng sa kaho ea meralo ea motheo ea matla lefatšeng ka bophara.
