UMVELISI WE-ASTM API 5L Gr.b STEEL PIP ETSHAYINA
UMVELISI WE-ASTM A106 Gr.b ENGATHUNGEYO UMbhobho WEntsimbi
UKUBONELELA NGE-ASTM API 5L Gr.b SCH 40 SCH 80
Elona XABISO ELIHLE LE-ASTM A53 B I-CARBON YE-STEEL IPIPI
Yintoni i-API 5L:
I Iziko lePetroleum laseMelika (API),yasekwa ngowe-1919,ngowona mbutho mkhulu wepetroleum kunye negesi yendalo eMelika.
Umele ntoni u5L:
I-5L imele kwiinkcukacha zemibhobho yensimbi: - Ngelizwi, umgca we-API 5L ngumbhobho we-carbon steel osetyenziswa kwisakhelo sokuhanjiswa kwe-oyile kunye negesi.Ngeli xesha ulwelo olwahlukileyo olunjengomphunga, amanzi, uludaka ngokufanayo lunokuthatha isiqhelo se-API 5L ngeenjongo zothumelo.Ujongano lwenkqubo ye-5L ibandakanya iintlobo zokuhlanganisa ezidityanisiweyo kunye nezihambelanayo.I-American Petroleum Institute iinkcukacha ze-API 5L igubungela umbhobho womgca wentsimbi ongaguqukiyo kunye ne-welded.Lo ngumbhobho wentsimbi wesikhokelo sothutho lwemibhobho kwishishini lepetroli kunye negesi enokutsha.I-interface yeprogram ye-5L ifanelekile ukugqithisa igesi, amanzi kunye neoli.Ujongano lwenkqubo iSpec 5L nguMgangatho waMazwe ngaMazwe omisela izinto ezifunekayo ukuze kudityaniswe amanqanaba eenkcukacha zezinto ezimbini.
Yazi ngakumbi ngePSL 1 kunye nePSL 2:
I-PSL 1 kunye ne-PSL 2 ziyimibhobho yentsimbi engaguqukiyo kunye ne-welded ukuze isetyenziswe kwimigaqo yokuthutha imibhobho kumashishini epetroli kunye negesi yepetroleum.
I-PSL1 isetyenziswa ngokubanzi elingana ne-ASTM A106 B kunye ne-A53 B.
I-PSL2 inexabiso elingqongqo ngakumbi kwimichiza kunye ne-mechanical strenth.Ngaphezulu kwe-PSL2 kufuna iindlela zovavanyo ezongezelelekileyo ezifana noVavanyo oluPhamayo, i-CVN Impact Test, i-DWT njl.
Amabanga afundiswayo ngala manqaku ngamaBakala A25 asemgangathweni,A,B,X42,X46,X52,X56,X60,X65,X70 kunye X80;kunye nawo nawaphi na amabakala aphakathi.
API 5L Ulwazi ngokubanzi:
Inkcazo ye-API SPEC 5L ibonelela ngemigangatho yombhobho ofanelekileyo ukusetyenziswa ekuhambiseni igesi, amanzi, kunye neoli kwi-gas yendalo kunye namashishini e-oyile.I-API SPEC 5L igubungela umbhobho womgca wensimbi ongenamthungo kunye ne-welded.Iquka i-plain-end, i-threaded-end, kunye ne-belled-end pipe, kunye ne-flowline (TFL) umbhobho, kunye nombhobho ophethe iziphelo ezilungiselelwe ukusetyenziswa kunye nokudibanisa okukhethekileyo.
Umbhobho owenziwe kwi-ASTM106 iBanga A okanye B awutshintshiswano nge-API 5L.Iimfuno kwi-API 5L X amabakala angqongqo kakhulu;amabakala aqengqelekayo awamkelekanga kwaye ukusetyenzwa kwakhona akuvumelekanga.Ngaphezu koko, ingqalelo ekhethekileyo inikwa ukuqina kunye novavanyo lokuqina kwiinkonzo ezimuncu kunye noxinzelelo oluphezulu kunye neeklasi zobushushu.
Amanqanaba okuqina kunye neDesulphurization:
I-Manganese sulphides zizinto eziqhelekileyo zokufakwa kuzo zonke iintsimbi ezenziwe nge-manganese.Ngenxa yokuba zikholisa ukwahlula okukhokelela ekunciphiseni amandla empembelelo, umxholo wesalfure kufuneka uncitshiswe.
Usetyenziso lwe-API 5L:
Ukuthuthwa kwegesi, amanzi kunye ne-oyile - ekhethwayo kwimibhobho emide ngenxa yokungabizi kakhulu kwentsimbi yePipeline - ukuxhathisa kwi-crack propogation.
Xa uqhagamshelwe i-API 5L Gr.b okanye i-A106 Gr.b ipayipi yensimbi, enye i-fitting and flanges inokutshintshwa kunye nokutshintshwa.Ukuba nguwelooking for ASTM A105 carbon izifakelo umbhobho yentsimbi ezifana nokufakwa kwemibhobho, flanges, iziqhoboshi kunye gaskets.I-JINBAICHENG METALIngumthengisi olungileyo, sithengisa kwaye sinikezela ngoluhlu olupheleleyo lwe-API 5L yeBanga B iMibhobho engenamthungo kunye neMibhobho eWelded, A106 Gr.B imibhobho engenamthungo enobuninzi kunye nexabiso eliphantsi, wamkelekile ukuba usitsalele umnxeba.
