Mehleng ena ea hona joale ea nts'etsopele e potlakileng indastering ea kaho le meralo ea motheo, litharollo tsa liphaephe tse tšepahalang le tse tšoarellang li fetohile senotlolo sa katleho ea projeke. Jwalo ka moetsi ea ka sehloohong oa liphaephe tsa tšepe tse potolohang le lihlahisoa tsa ho koahela liphaephe Chaena, Cangzhou Spiral Steel Pipes Group Co., Ltd. e qalilePhaephe ea Mohala ea X70 SSAW, e hlalosang moloko o mocha oa litekanyetso tsa Line Pipe ka ts'ebetso ea eona e ikhethang.
Phaephe ea X70 ke sehlahisoa sa mantlha sa tšepe ea phaephe ea boemo bo holimo, e nang le matla a tlhahiso a fetang 485 MPa, e khomarelang litekanyetso tse thata joalo ka API 5L le GB/T 9711. E kopanya matla a phahameng le ho tiea ho hoholo 'me e ka sebetsana habonolo le liphephetso tse ngata tse kang khatello e phahameng le ho tiea lits'ebetsong tsa ka tlas'a lefatše. E amohela ts'ebetso ea ho welding ea arc e tsoetsoeng ka tlas'a lefatše e tsoetseng pele (SSAW), moo moqomo oa tšepe o robehang ka helikopthara ebe o welded. Khatello ea weld e ajoa ka ho lekana, e fa phaephe matla a makatsang a khatello le ho hanyetsa ho tiea, haholo-holo e loketseng liphaephe tsa khase tse ka tlas'a lefatše, boenjiniere ba motheo, le maemo a mang a bohlokoa. Litlhaloso tsa sehlahisoa li tloha ho 219mm ho isa ho 3500mm, ka bolelele bo le bong ho fihlela ho limithara tse 35, li fihlela litlhoko tsa meralo ea motheo e fapaneng e meholo le lits'ebetso tse ikhethileng.
Ho latela pokello ea tekheniki ho tloha ha e theoa ka 1993, Cangzhou Spiral Steel Pipes Group Co., Ltd. ke mokhatlo o matla: fektheri ea eona e akaretsa sebaka sa lisekoere-mithara tse 350,000, ka thepa eohle ea li-yuan tse limilione tse 680, 'me e na le basebetsi ba 680. Bokhoni ba eona ba tlhahiso ea selemo le selemo ba liphaephe tsa tšepe tse potolohang bo fihla lithane tse 400,000, ka boleng ba tlhahiso ea selemo le selemo ba li-yuan tse libilione tse 1.8. Khamphani e laola ka tieo ts'ebetso eohle ho tloha khethong ea thepa e tala ho ea tlhahlobong ea sehlahisoa, e etsa liteko tse ngata tse kang tlhahlobo ea radiographic le ho lemoha liphoso tsa ultrasound ho netefatsa bophelo ba ts'ebeletso bo tšoarellang nako e telele le ts'ebetso e tsitsitseng. Joaloka tharollo ea Line Pipe e kopanyang boleng le ho tenyetseha, X70 SSAWPhaephe ea MohalaHa e lokele feela bakeng sa ho tsamaisa khase le metsi ka tlas'a lefatše, empa hape e sebetsa hantle maemong a ho beha lipeipi tse hole le ho fetisetsa mokelikeli indastering, e leng se etsang hore e be khetho e tšepahalang bakeng sa merero ea meralo ea motheo ea lefats'e.
