UMENZI WE-ASTM API 5L Gr.b STEEL PIP ECHINA
MKHIQIZI WE-ASTM A106 Gr.b ENGATHUMELI IPIPI LESIMBA
UKUNIKEZWA KWE-ASTM API 5L Gr.b SCH 40 SCH 80
INANI ELIHLE KAKHULU LE-ASTM A53 B I-CARBON STEEL PIPIPI
Yini i-API 5L:
I I-American Petroleum Institute (API),yasungulwa ngo-1919,iyinhlangano enkulu yemboni ye-petroleum negesi yemvelo e-United States.
Isho ukuthini i-5L:
5L imelela emibhalweni yensimbi:- Ngegama nje, ulayini we-API 5L yipayipi lensimbi ye-carbon elisetshenziswa ohlakeni lokudluliswa kukawoyela negesi.Okwamanje uketshezi oluhlukile olufana nomusi, amanzi, udaka ngokufanayo lungathatha inkambiso ye-API 5L ngezinjongo zokudlulisela.I-Programming interface 5L imininingwane ihlanganisa izinhlobo zokuhlanganisa ezishiselwe futhi ezingaguquki.I-American Petroleum Institute imininingwane ye-API 5L ihlanganisa ipayipi lensimbi elingaguquki nelishiselwe.Leli ipayipi lensimbi lezinhlaka zokuthutha zamapayipi kuphethiloli kanye negesi evuthayo.I-Programming interface 5L ifanele ukudlulisa igesi, amanzi, namafutha.I-Programming interface I-Spec 5L iyiZinga Lomhlaba Wonke elinquma izimfuneko zokuhlanganisa amaleveli emininingwane yezinto ezimbili
Yazi okwengeziwe nge-PSL 1 ne-PSL 2:
I-PSL 1 kanye ne-PSL 2 ngamapayipi ensimbi angashintshi futhi ashiselwe ukuze asetshenziswe ezinhlelweni zokuthutha zamapayipi ebhizinisini likaphethiloli negesi kaphethiloli.
I-PSL1 ivamise ukusetshenziswa okulingana ne-ASTM A106 B kanye ne-A53 B.
I-PSL2 inevelu eqine kakhulu kumakhemikhali namandla wemishini.Ngaphezulu kwe-PSL2 kudinga izindlela zokuhlola ezengeziwe njenge-None Distructive Test, CVN Impact Test, DWT njll.
Amabanga afakwe kulokhu kucaciswa angamabanga ajwayelekile A25,A,B,X42,X46,X52,X56,X60,X65,I-X70 ne-X80;kanye nanoma imaphi amabanga aphakathi.
Ulwazi Olujwayelekile lwe-API 5L:
Ukucaciswa kwe-API SPEC 5L kunikeza izindinganiso zamapayipi afanele ukusetshenziswa ekudluliseni igesi, amanzi, namafutha ezimbonini zegesi yemvelo nezowoyela.I-API SPEC 5L ihlanganisa ipayipi lensimbi elingenamthungo nelishiselwe.Ihlanganisa ipayipi elingenalutho, eline-threaded-end, ne-belled-end, kanye nepayipi le-through-the-flowline (TFL), kanye nepayipi elineziphetho ezilungiselelwe ukusetshenziswa nama-couplings akhethekile.
Ipayipi elakhelwe ku-ASTM106 Ibanga A noma B alishintsheki ne-API 5L.Izidingo zamamaki e-API 5L X ziqine kakhulu;amamaki agoqiwe awamukelekile futhi ukusebenza kabusha akuvunyelwe.Ngaphezu kwalokho, ukunaka okukhethekile kunikezwa ekuhlolweni kokuqina nokuqina kwezinsizakalo ezimuncu kanye nengcindezi ephezulu namakilasi okushisa.
Amazinga Amandla kanye Ne-Desulphurization:
I-Manganese sulphides iyinhlanganisela evamile kuzo zonke izinsimbi ze-manganese alloyed.Ngenxa yokuthi zivame ukuhlukanisa okuholela ekunciphiseni kwamandla omthelela, okuqukethwe kwesibabule kudinga ukuncishiswa.
Izinhlelo zokusebenza ze-API 5L:
Ukuthuthwa kwegesi, amanzi kanye nowoyela - okuthandwa ngamapayipi amade ngenxa yokungabizi kwensimbi yepayipi - ukumelana nokuqhekeka.
Uma kuxhunyiwe i-API 5L Gr.b noma i-A106 Gr.b ipayipi lensimbi, okunye ukulingana nama-flange kungase kushintshwe futhi kushintshe.Uma unguwelilungiselela ukufakwa kwepayipi lensimbi le-ASTM A105 le-carbon steel njengokufakwa kwamapayipi, ama-flange, izinsimbi nama-gaskets.I-JINBAICHENG METALIungumdayisi omuhle, sibeka futhi sinikezela ngohlu olugcwele lwe-API 5L Grade B Amapayipi Angenamthungo namapayipi Ashiselwe, A106 Gr.B amapayipi angenamthungo anenani eliningi namanani ashibhile, wamukelekile ukusishayela.
