Labarai - China da Rasha sun rattaba hannu kan yarjejeniyar bututun iskar gas na Power of Siberia-2. Kamfanin Royal Steel ya bayyana aniyarsa ta tallafawa ci gaban kasar gaba daya.

A watan Satumba, China da Rasha sun rattaba hannu kan yarjejeniyar bututun iskar gas na Power of Siberia-2. Bututun, wanda za a gina ta Mongolia, yana da nufin samar da iskar gas daga filayen iskar gas na yammacin Rasha zuwa China. Tare da tsarin samar da wutar lantarki mai karfin cubic mita biliyan 50 a kowace shekara, ana sa ran zai fara aiki a kusan shekarar 2030.

Ƙarfin Siberia-2 ya fi kawai bututun makamashi; wani babban madauri ne na sake fasalin tsarin duniya. Yana lalata ikon mallakar makamashin Yammacin duniya, yana zurfafa haɗin gwiwa tsakanin Sin da Rasha, kuma yana ƙarfafa ƙarfin tattalin arziki na yanki. Hakanan yana ba da misali mai amfani na haɗin gwiwa mai cin nasara a cikin duniyar da ke da yankuna da yawa.

Bututun Wutar Lantarki na Siberia 2: A matsayin babban kayan aikin, bututun ƙarfe na X90 zai gudanar da jigilar iskar gas mai nisa daga filayen iskar gas na Yammacin Siberian Rasha zuwa Arewacin China. Bayan ƙaddamar da shi a shekarar 2030, ana sa ran yawan watsa iskar gas na shekara-shekara zai kai sama da kashi 20% na jimillar iskar gas da China ke shigowa da su daga bututun.

Layin Bututun Iskar Gas na Tsakiyar Asiya D: A yankunan ƙasa mai yawan gishiri a ɓangaren Uzbek, bututun ƙarfe na X90, tare da tsarin kariya na 3PE + cathodic, yana da tsawon rayuwar aikinsa har zuwa shekaru 50.

Rufin 3PE ya ƙunshi fenti mai rufi na epoxy (FBE), wani yanki mai mannewa, da kuma rufin rufin polyethylene (PE), mai kauri ≥2.8mm, wanda ke samar da tsarin kariya mai "tsauri + sassauƙa":

Tsarin tushe na FBE, wanda kaurinsa ya kai 60-100μm, yana ɗaurewa da saman bututun ƙarfe ta hanyar sinadarai, yana ba da kyakkyawan mannewa (≥5MPa) da juriya ga narkar da cathodic (radius na barewa ≤8mm a 65°C/48h).

Manne Mai Matsakaici: Kauri 200-400μm, an yi shi da resin EVA da aka gyara, yana manne da FBE da PE, tare da ƙarfin barewa na ≥50N/cm don hana rabuwa tsakanin layukan.
