Wareegga cad & PCCP silig
Silig wareeg ah oo cad waa badeecadayada dhaqameed ee leh taariikhda wax soo saarka ugu dheer ee Silvery Dragon.Alaabtani waxa ay ku haboon tahay hurdo tareen shubka ah oo hore loo sii adkeeyey, saxan shub ah iyo tuubo shub ah, iwm. Dhexroorkiisu waxa uu u dhexeeyaa φ4.0mm ilaa φ12.0mm iyo xoog xajin laga bilaabo 1470 ilaa 1960MPa.Xajmiga xajmiga alaabtani waa sax;tayada dusha sare waa mid aad u fiican, hantida farsamada waa lebis;adkaanta ayaa wanaagsan;xoogga buttoning waa sare.Waa diiqada dib loo soo nooleeyay iyo nasasho yar, dhanka kale daalkeeda iyo xogta embrittlement hydrogen ayaa ka sarreeya heerarka caalamiga ah.Tiro badan ayaa loo dhoofiyaa suuqyo shisheeye tobankii sano ee la soo dhaafay.
Silvery Dragon waa shirkaddii ugu horreysay ee R & D ee siligga birta ah ee Pre-stressed ee PCCP ee Shiinaha, shirkad dejineed heer qaran ah iyo alaab-qeybiye heersare ah oo leh karti, tignoolajiyada, tayada iyo faa'iidooyinka waxqabadka.Alaabtayadu waxay had iyo jeer ku jireen booska ugu horreeya ee warshadaha laga soo bilaabo horumarinta alaabta ceeriin, horumarinta khadka wax soo saarka si toos ah, baaritaanka xasaasiyadda anti-hydrogen embrittlement.Dhanka kale, Silvery Dragon wuxuu kaloo diyaariyey GB/T5223 iyo heerarka PCCP Shiinaha.Tan iyo 2001, wax soo saarka Silvery Dragon ayaa loo isticmaalay in ka badan 80 mashruuc biyo leexin muhiim ah oo dhexroor ka 2.0-4.0m PCCP, sida mashruuca ka leexinta biyaha webiga Irtysh ilaa Urumqi, South-Waqooyi biyaha leexinta qaybta Beijing, Henan qaybta & Hebei qaybta, Mashruuca gaadiidka biyaha ee Mopanshan ee Harbin, Shenyang Dahuofang Project, wajiga labaad ee mashruuca wabiga jaalaha ah ee Shanxi iyo Mashruuca Qaybta Biyaha ee Waqooyi-Galbeed.Tirada guud waxay dhaaftay 1,200,000ton.Sidoo kale, waxaan u dhoofinay suuqyada dibadda, sida Masar, Kanada iyo iwm. Marka laga reebo heerka qaranka GB/T5223, waxaan sidoo kale la kulmi karnaa ASTMA648, NFEN642 iyo heerarka kale ee caalamiga ah iyo qeexitaanka macaamiisha gaarka ah.
