Dab tsi yog cov qib sib txawv thiab cov ntsiab lus ntawm API 5L kav dej?

API 5L roj pipeline yeeb nkab yog cov kav dej uas thauj cov roj, roj thiab dej hauv av mus rau cov chaw lag luam roj thiab roj. Cov kav dej muaj xws li cov kav dej seamless thiab welded steel kav, thiab lawv cov xaus muaj xws li cov xaus, threaded xaus thiab qhov (socket) xaus. Qee cov qhab nia uas nquag siv suav nrog:

API 5L Qib B: Qhov tsawg kawg nkaus tawm lub zog ntawm Qib B yeeb nkab yog 35, 000 psi (241 MPa), uas siab dua Qib A thiab muaj cov khoom siv zoo. Nws yog siv nyob rau hauv daim ntawv thov uas yuav tsum tau me ntsis siab dua los yog lub zog, xws li nruab nrab thiab tsis tshua muaj siab natural gas kis pipelines, sib sau ua ke systems, thiab cov txheej txheem pipelines ntawm cov roj thiab roj chaw.
API 5L X42: Qhov tsawg kawg nkaus tawm lub zog yog 42, 000 psi (290 MPa). Nws yog dav siv nyob rau hauv cov roj thiab roj hla teb chaws pipelines. Nws lub zog thiab toughness yog haum rau nruab nrab siab thiab kub hauv kev thauj mus los ntev. Nws cuam tshuam qhov sib npaug ntawm lub zog thiab tus nqi-zoo thiab yog qhov kev xaiv nrov rau cov phiaj xwm kav dej.
API 5L X52: Qhov tsawg kawg nkaus tawm lub zog yog 52, 000 psi (359 MPa). Nws muaj zog dua thiab kav ntev dua cov qib qis. Nws yog siv nyob rau hauv high-pressure pipelines, offshore thiab high-stress ib puag ncig. Lub zog muaj zog tuaj yeem txo cov phab ntsa thickness, txo cov nqi thiab tswj lub siab muaj peev xwm.
API 5L X60: Yam tsawg kawg nkaus yield zog 60, 000 psi (414 MPa), superior zog tshaj X42, X52, thiab lwm yam., siv rau kev kub siab los yog hnyav ib puag ncig daim ntaub ntawv xws li siab kub siab natural gas kis pipelines thiab offshore platforms.
API 5L X65: Yam tsawg kawg nkaus yield zog 65, 000 psi (448 MPa), zoo heev zog thiab toughness, siv rau kev kub siab natural gas kis, hnyav siv xws li kua qaub thiab Arctic, haum rau tej yaam num uas yuav tsum tau muaj zog, toughness thiab tsis kam mus rau ib puag ncig yam.
API 5L X70: Yam tsawg kawg nkaus yield zog 70, 000 psi (483 MPa), ib qho ntawm cov qib siab zog, siv rau cov ntawv thov tseem ceeb xws li cov kav dej ntev ntev thiab cov chaw sab nrauv, tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv thaj chaw nyuaj lossis siab. kev ntxhov siab, huab cua kub ib puag ncig.
API 5L X80: Yam tsawg kawg nkaus yield zog 80, 000 psi (552 MPa), yog qib siab tshaj ntawm API 5L, tsim rau ultra-siab siab daim ntaub ntawv, xws li cov dej tob hauv ntug dej hiav txwv los yog roob hla cov kav dej, tuaj yeem txo cov phab ntsa tuab, thiab ua tiav kev sib zog thiab kev siv nyiaj txiag ntau dua.
