Bututun iskar Gas na Gabas tsakanin Sin da Rasha: Yin amfani da ƙarfe na X80 a ko'ina, yana watsa mita biliyan 38 na gas a kowace shekara kuma yana ratsa permafrost da wuraren da ke da girgizar ƙasa, yana kafa ma'auni na duniya don fasahar gine-ginen kan teku.

Aikin bututun iskar Gas na Yamma- Gabas III: X80 bututun karfe yana da sama da 80% na jimlar amfani, yana tallafawa ingantaccen jigilar iskar gas daga yammacin kasar Sin zuwa yankin Delta na Kogin Yangtze.
Ci gaban mai da iskar gas mai zurfi: A aikin samar da iskar gas na Liwan 3-1 a tekun kudancin kasar Sin, ana amfani da bututun karfe na X80 maras sumul don bututun karkashin ruwa a zurfin ruwa da ya wuce mita 1,500, tare da karfin matsa lamba na waje na 35 MPa.

Karfe X90 yana wakiltar ƙarni na uku na manyan bututun bututun ƙarfe, wanda ya dace da daidaitaccen bugu na API 5L 47th. Yana da mafi ƙarancin ƙarfin amfanin gona na 621 MPa, ƙarfin juzu'i na 758-931 MPa, da kuma daidaitaccen carbon (Ceq) na 0.47% ko ƙasa da haka. Babban fa'idodinsa sun haɗa da tanadin ƙarfi mafi girma, haɓakar walƙiya, da daidaitawar ƙarancin zafin jiki.

Abubuwan aikace-aikace na yau da kullun sun haɗa da:

Power of Siberiya 2 Pipeline: A matsayin ainihin 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 kaddamar da shi a shekarar 2030, ana sa ran yawan iskar iskar gas na shekara-shekara zai kai sama da kashi 20 cikin 100 na yawan iskar gas da kasar Sin ta shigo da su daga waje.

Layin Gas Gas na Tsakiyar Asiya D: A cikin yankunan ƙasa mai gishiri mai yawa na sashin Uzbek, bututun ƙarfe na X90, haɗe tare da tsarin kariyar 3PE + cathodic, yana da tsawon rayuwar sabis har zuwa shekaru 50.

A 3PE shafi kunshi wani epoxy foda shafi (FBE) primer, wani m matsakaici Layer, da kuma polyethylene (PE) topcoat, tare da jimlar kauri na ≥2.8mm, forming a "m + m" hadaddun tsarin kariya:

FBE tushe Layer, tare da kauri na 60-100μm, chemically bonds zuwa karfe bututu surface, samar da kyau kwarai mannewa (≥5MPa) da kuma cathodic disbondment juriya (bawo radius ≤8mm a 65 ° C / 48h).

Manne tsaka-tsaki: 200-400μm lokacin farin ciki, wanda aka yi da gyare-gyaren EVA resin, ta jiki tare da FBE da PE, tare da ƙarfin kwasfa na ≥50N / cm don hana rabuwar interlayer.
PE na waje: ≥2.5mm lokacin farin ciki, wanda aka yi da polyethylene mai girma (HDPE), tare da ma'aunin laushi na Vicat ≥110 ° C da UV tsufa juriya da aka tabbatar ta hanyar gwajin fitilar xenon arc 336-hour (tsarin ƙarfin ƙarfi ≥80%). Ya dace don amfani a cikin ciyayi na Mongolian da wuraren permafrost.

Royal Steel Group, tare da manufar "Material Innovation Driving the Energy Juyin Halitta," ya ci gaba da samar da babban aiki, ingantaccen ingantaccen samfuran bututun ƙarfe da sabis na fasaha don gina kayayyakin makamashi na duniya.
