API 5L ke eng:
The Setsi sa Amerika sa Petroleum (API),e thehiloe ka 1919,ke mokhatlo o moholo ka ho fetisisa oa indasteri ea peterole le khase ea tlhaho United States.
5L e emetse eng?:
5L e emetse litlhaloso tsa lipeipi tsa tšepe:- Ka lentsoe le le leng, API 5L line ke peipi ea tšepe ea carbon e kentsoeng moralong oa phetiso ea oli le khase.Ka nako e ts'oanang, lino tse fapaneng tse kang mouoane, metsi, slurry le tsona li ka nka tloaelo ea API 5L molemong oa phetisetso.Lintlha tsa sebopeho sa 5L li akaretsa mefuta e kopanyang ka li-welded le tse tsitsitseng.Lintlha tsa American Petroleum Institute API 5L e akaretsa phala e tsitsitseng le e cheselitsoeng ea tšepe.Ena ke peipi ea tšepe bakeng sa meralo ea lipeipi tsa lipeipi khoebong ea peterole le khase e tukang.Lenaneo la 5L le loketse ho fetisa khase, metsi le oli.Lenaneo la Spec 5L ke Maemo a Machabeng a khethang litlhokahalo tsa ho bokelloa ha lintlha tse peli tsa lintlha.
Tseba haholoanyane ka PSL 1 le PSL 2:
PSL 1 le PSL 2 ke tsa lipeipi tsa tšepe tse tsitsitseng le tse cheselitsoeng bakeng sa ho sebelisoa meralong ea lipeipi tsa lipeipi likhoebong tsa peterole le khase ea peterole.
PSL1 hangata e sebelisoa e lekanang le ASTM A106 B le A53 B.
PSL2 e na le boleng bo thata ho matla a lik'hemik'hale le a mochini.Ho feta PSL2 ho hloka mekhoa e mengata ea liteko joalo ka None Disstructive Test, CVN Impact Test, DWT jj.
Limaraka tse fanoeng ke litlhaloso tsena ke limaraka tse tloaelehileng tsa A25,A,B,X42,X46,X52,X56,X60,X65,X70 le X80;le limaraka life kapa life tsa mahareng.
Lintlha tse akaretsang tsa API 5L:
Tlhaloso ea API SPEC 5L e fana ka litekanyetso tsa lipeipi tse loketseng ho sebelisoa ho tsamaisa khase, metsi le oli indastering ea khase ea tlhaho le oli.API SPEC 5L e koahela phala ea tšepe e sa tsitsang le e cheselitsoeng.E kenyelletsa phala e hlakileng, e nang le thread, andbelled-end pipe, hammoho le phaephe ea through-the-flowline (TFL), le pipe e nang le lipheletso tse lokiselitsoeng ho sebelisoa ka li-couplings tse khethehileng.
Pipe e entsoeng ho ASTM106 Kereiti A kapa B ha e feto-fetohe le API 5L.Litlhoko tsa limaraka tsa API 5L X li thata ho feta;limaraka tse kolokisitsoeng ha li amoheloe ebile ha ho lumelloe ho sebetsa bocha.Ho feta moo, tlhokomelo e khethehileng e fanoa litekong tse thata le tse thata bakeng sa lits'ebeletso tse bolila le lihlopha tse phahameng tsa khatello le mocheso.
Maemo a Matla le Desulphurization:
Manganese sulphides ke lintho tse tloaelehileng tse kenyelletsoeng litšepeng tsohle tsa manganese alloyed.Hobane li atisa ho arola ho fella ka ho fokotseha ha matla a ts'usumetso, lihlahisoa tsa sulphure li hloka ho fokotsoa.
Lisebelisoa tsa API 5L:
Lipalangoang tsa khase, metsi le oli - tse ratoang liphaepheng tse telele ka lebaka la theko e tlaase ea tšepe ea Pipeline - ho hanyetsa ho pepeseha.
Ha o hoketsoe API 5L Gr.b kapa A106 Gr.b pipe ea tšepe, li-fitting tse ling le li-flange li ka fapanyetsanoa.Haeba ke uenalho batla lipeipi tsa tšepe tsa ASTM A105 tsa carbon steel joalo ka liphaephe, li-flange, li-fasteners le li-gaskets.JINBAICHENG TŠEPEke morekisi ea hloahloa, re boloka le ho fana ka mefuta e felletseng ea API 5L Grade B Seamless Pipes and Welded Pipes, A106 Gr.Liphaephe tse seamless tse nang le bongata bo bongata le theko e tlase, rea u amohela ho re letsetsa.
