Isingeniso somkhiqizo
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-thry-the-flowline (TFL), kanye nepayipi elineziphetho ezilungiselelwe ukusetshenziswa nokuhlanganisa okukhethekile.

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 & Nesulphurization
I-Manganese sulphides iyinhlanganisela evamile kuzo zonke izinsimbi ze-manganese alloyed. Ngenxa yokuthi zivame ukuhlukanisa okuholela ekunciphiseni kwamandla omthelela, okuqukethwe kwesibabule kudinga ukuncishiswa. Sicacisa umkhawulo ongu-0.007%.
Izinzuzo ze-API 5L Nezicelo Zokuthutha igesi, amanzi namafutha - kukhethwa ngamapayipi amade ngenxa yokungabizi
Insimbi yepayipi - ukumelana nokuqhekeka kwe-crack propogation
Line Pipe / Sour Service Line Pipes API Standard Specification for Line Pipe
I-American Petroleum Institute specification API 5L ikhuluma ngepayipi lensimbi engenamthungo nelishiselwe kumasistimu okuthutha amapayipi ezimbonini ze-petroleum negesi yemvelo. I-API 5L ilungele ukuthutha igesi, amanzi, namafutha.
Imininingwane ye-API 5L ibambelela ku-International Organisation for Standardization ISO 3183, imisa amasistimu okuthutha amapayipi ngaphakathi kwezinto zokwakha, okokusebenza kanye nezakhiwo zasogwini zezimboni zegesi yemvelo, i-petroleum, ne-petrochemical. Lapho ligunyaza amazinga, ikomiti lezobuchwepheshe libone ukuthi kukhona Amazinga Okucaciswa Komkhiqizo amabili ayisisekelo (PSL) ezimfuneko zobuchwepheshe futhi ngenxa yalokho yathuthukisa i-PSL 1 kanye ne-PSL 2. I-PSL 1 iyikhwalithi evamile yepayipi likalayini lapho i-PSL 2 iqukethe amakhemikhali engeziwe, izakhiwo zemishini. , kanye nezidingo zokuhlola.
Amabanga afakwe kulokhu kucaciswa A25, A, B kanye "X" Amabanga X42, X46, X52, X56, X60, X65, X70, kanye X80. Izinombolo zamadijithi ezimbili ezilandela u-"X" zikhombisa Amandla Esivuno Esincane (ngo-000's psi) wepayipi elikhiqizwe kuleli banga.
