Iindaba - I-ASTM A106 vs API 5L: Ngowuphi uMgangatho wePipe yeNsimbi kwiProjekthi yakho?

Kubaphathi beeprojekthi zehlabathi, abalawuli bokuthenga, kunye neenkokheli zobunjineli, ukukhetha iinkcukacha ezifanelekileyo zemibhobho sisigqibo esithatha ixesha elide esichaphazela ukhuseleko, uhlahlo lwabiwo-mali, kunye nobomi beprojekthi. Xa kuphakwa ioyile, igesi, okanye ulwelo olunoxinzelelo oluphezulu, iikhowudi ezimbini zihlala zivela: i-ASTM A106 kunye ne-API 5L.

Nangona zombini zisebenza kwimibhobho yentsimbi yekhabhoni kwaye zineempawu ezifanayo zeekhemikhali kunye nezoomatshini, ukuzibhidanisa kunokubangela ukungathotyelwa kwemithetho okubizayo okanye ukungaphumeleli kwangethuba kwemibhobho.

Nantsi inkcazo yobuchwephesha ukuze wazi ukuba yeyiphi ehambelana nohlobo lweprojekthi yakho.

Ububanzi kunye nesicelo esingundoqo

Umahluko ophambili phakathi kwale migangatho mibini kukuba ibhalwe kwiindawo ezahlukeneyo zokusebenza:

Umbhobho wentsimbi we-ASTM A106: Yenzelwe inkonzo engenamthungo kubushushu obuphezulu kunye noxinzelelo oluphezulu. Isetyenziswa kakhulu kwimibhobho yokucocwa kweoyile, isikhululo samandla, isikhululo sepetrochemical kunye nokusetyenziswa kwebhoyila apho ulwelo lunobushushu obuphezulu.

Umbhobho weNtsimbi we-API 5L: Ngumgangatho ophuhliswe yi-American Petroleum Institute wokusetyenziswa kwemibhobho kwiinkqubo zothutho lweepayipi ezihambelanayo kumashishini eoyile negesi yendalo. Yenzelwe ukuthwala igesi, amanzi, kunye neoyile kumgama omde kunye nexesha elide emhlabeni naselunxwemeni.

Iindlela Zokuvelisa: Ezingenamthungo vs. Ezidibeneyo

Ukuguquguquka kwimveliso kukwayindlela ebalulekileyo yokwahlulahlula ucwangciso lokuthenga:

Ukuveliswa kwemibhobho yentsimbi yekhabhoni engenamthungo (iiBakala A, B, kunye no-C) yeyona ndlela ifumanekayo ye-ASTM A106.

I-API 5L ibandakanya ulungelelwaniso lwemibhobho engenamthungo nedibeneyo kwiimfuno zemibhobho enobubanzi obukhulu. Iindidi ezidibeneyo yi-API 5L ERW pipe (Electric Resistance Welded), i-LSAW steel pipe (Longitudinal Submerged Arc Welded), i-SSAW steel pipe (Spiral Submerged Arc Welded).

Amabanga ezinto kunye noBume beeKhemikhali

Ukuqonda inkqubo yokubeka amanqaku kubalulekile ekubalweni kolwakhiwo kunye nokulinganiswa koxinzelelo:

Umgangatho	Amabanga aqhelekileyo	Amandla okuThamba (Umn)	Amandla Okuvelisa (Umda)
I-ASTM A106	Ibanga A, ASTM A106 Ibanga B, Ibanga C	I-415 MPa (Ibanga B)	240 MPa (Ibanga B)
I-API 5L	API 5L Grade B, API 5L X42, API 5L X52, API 5L X60, API 5L X65, API 5L X70	415 MPa (Ibanga B) ukuya kwi-570 MPa (X70)	245 MPa (Ibanga B) ukuya kwi-485 MPa (X70)

Umahluko kwiMetallurgy:

Ngelixa i-ASTM A106 Grade B kunye ne-API 5L Grade B zinemilo yeekhemikhali efanayo kakhulu kunye nemida yoomatshini, i-API 5L ingenisa intsimbi eqengqelekayo enamandla aphezulu (ii-grades "X", njengepayipi yomgca we-API 5L X65). Ezi grades ziphezulu zivumela iindonga ezincinci kwiipayipi ezikude, nto leyo enciphisa kakhulu iindleko zetoni zentsimbi iyonke kunye neendleko zokuthutha kwiiprojekthi ezinkulu zeziseko zophuhliso.

Amanqanaba eNkcazelo yeMveliso: PSL1 vs. PSL2

Impazamo ephambili eyenziwa ngabathengi bamazwe ngamazwe kukungawahoyi amanqanaba enkcazo yemveliso ye-API 5L (PSL1 kunye nePSL2):

I-PSL1ibonelela ngenqanaba lomgangatho oqhelekileyo elilingana ne-ASTM A106.

I-PSL2ibeka iimfuno ezingqongqo neziyimfuneko kwimibhobho yentsimbi yekhabhoni. Iyalela uvavanyo lwempembelelo (uvavanyo lweCharpy V-notch) ukuvavanya ukuqina kokuqhekeka, inciphisa ngokungqongqo ukulingana kwekhabhoni ukuqinisekisa ukudityaniswa kakuhle, kwaye ifuna uvavanyo oluqinileyo olungatshabalalisiyo (NDE). I-ASTM A106 ayinayo i-equivalent equivalent kwiimfuno zePSL2.

Isikhokelo sesishwankathelo sabaphathi beProjekthi

Khetha i-ASTM A106 (Sch 40 / Sch 80):Ukuba iprojekthi yakho ibandakanya imibhobho enzima yokucoca imveliso yendawo, imibhobho yomphunga, okanye ulwakhiwo lweyunithi yokusebenza esebenza phantsi koxinzelelo lobushushu obuphezulu.

Khetha i-API 5L (X42 ukuya ku-X70):Ukuba wakha imibhobho yeoyile yamazwe ngamazwe, imibhobho yokuqokelela ioyile kunye neyokuthutha elwandle, okanye ufuna ububanzi obukhuluImibhobho yentsimbi edityanisiweyo ye-API 5Liyakwazi ukumelana noxinzelelo oluphezulu lwemveliso kunye neendawo ezinegesi ene-asidi.

Ukukhetha phakathi kwe-ASTM A106 kunye ne-API 5L kungaphezulu nje kwemibandela; kumalunga nokunciphisa umngcipheko, ukuvunywa kwemithetho, kunye nokwenza ngcono iindleko.

Njengomthengisi ohamba phambili kwihlabathi liphela, iRoyal Steel Group inikezela ngesiqinisekiso esipheleleyo nesivavanyiweyo kumzi-mvelisoUmbhobho wentsimbi yekhabhoni engenamthungo we-ASTM A106, ekumgangatho ophezuluUmbhobho womgca we-API 5L X60, kunye nodonga oluqinileyoUmbhobho wentsimbi we-LSAWukuhambelana nemigangatho yeprojekthi yamazwe ngamazwe, kuquka imigangatho ye-EN, i-ASME, kunye ne-ISO.
