Pipeline steel yeeb nkab
Zhengde API pipeline steel yeeb nkab yog cov yeeb nkab yeeb nkab uas yog los ntawm American Petroleum Standard. Lub raj xa dej yog siv los thauj cov roj, chav, thiab cov dej tawm hauv av mus rau cov chaw lag luam roj thiab roj los ntawm cov kav dej. Cov kav dej muaj xws li cov kav dej seamless thiab welded steel kav, thiab cov yeeb nkab kawg muaj qhov xaus, threaded xaus thiab qhov (socket) xaus; txoj kev sib txuas yog kawg vuam, dab tshos txuas, qhov (socket) txuas, thiab lwm yam.
Kev tsim cov high-qib kab kav siv micro- txheej txheem kev kho cua sov. Tus nqi tsim khoom ntawm stainless hlau seamless kav yog pom tseeb siab dua li cov kav hlau welded, thiab nrog kev txhim kho cov qib steel, xws li X80 thiab siab dua steel qib kab kav, tsis muaj cov pa roj carbon sib npaug. Cov txheej txheem ntawm seam steel yeeb nkab yog qhov nyuaj kom ua tau raws li cov neeg siv khoom xav tau; tag nrho 12Cr1moV alloy yeeb nkab tuam ntxhab tau ua cov kev tshawb fawb tshawb fawb los txhim kho cov kev tiv thaiv corrosion ntawm lawv cov kav dej thiab txhim kho kev ua haujlwm hauv qhov kub thiab txias.

Peb Qhov Zoo
API
API yog cov lus Askiv luv ntawm American Petroleum Institute. Qib qhia: thawj ob tus lej ntawm qhov tsawg kawg nkaus tus nqi ntawm Teb Chaws Asmeskas lub zog tawm los. Siv X80 ua piv txwv: X80 yog qhov tsawg kawg nkaus tawm lub zog ntawm cov yeeb nkab steel yeeb nkab 80000psi (552MPa) PSI English lub npe tag nrho yog Pounds ib square inch. P yog phaus, S yog square, thiab kuv yog nti. Nws tuaj yeem suav tau los ntawm kev hloov tag nrho cov chav nyob rau hauv metric units: 1psi=6.895kPa=0.06895bar European lub teb chaws thiab lwm lub teb chaws yog accustomed rau siv psi raws li chav tsev 1bar=0.1MPaM--thermomechanical tswj dov (TMCP tswj dov thiab tswj cua txias) N-Quenching thiab Q--normalizing (quenching + kub tempering) X42NB/X60QS/X65MS/X65MO.
Cov kev xav tau ntawm kev ua haujlwm
API cov kev xav tau (kev sib haum xeeb thiab kev ruaj ntseg ntawm kev ua tau zoo, qhov tseeb qhov tseeb, phaj duab hardening, Bauschinger nyhuv) kom tiv taus cov khoom zoo li qub thiab cov khoom siv hluav taws xob, kom tiv taus cov roj ntws yaig thiab corrosion, ambient kub, thiab geological tej yam kev mob ntawm steel zog. Installation Vuam zoo. High plasticity thiab toughness, tsis tshua muaj ductile- nkig hloov kub, vuam kev ua tau zoo, zoo heev tiv thaiv hydrogen-induced cracking thiab sulfide kev nyuaj siab corrosion cracking.
Saib xyuas kom meej
Yuav tsum tsis muaj kab nrib pleb, nti, folds, huab cua npuas, suav nrog thiab delaminations ntawm qhov chaw uas tsim kev puas tsuaj rau kev siv. Qhov saum npoo ntawm steel sawb tau tso cai kom muaj pits, concaves, khawb thiab lwm yam hauv zos tsis xws luag uas nws qhov tob lossis qhov siab tsis tshaj ib nrab ntawm cov thickness kam rau ua. Thiab qhov tsawg kawg nkaus thickness tso cai los ntawm steel sawb yuav tsum tau guaranteed. Qhov tob ntawm ntug kab nrib pleb thiab lwm yam tsis xws luag nyob rau hauv dav kev taw qhia yuav tsum tsis txhob ntau tshaj ib nrab ntawm qhov tso cai dav sib txawv thiab qhov tsawg kawg nkaus dav ntawm cov hlau sawb yuav tsum guaranteed. Qhov saum npoo ntawm cov yeeb nkab steel yuav tsum tsis muaj qhov tsis xws li khawb thiab khawb uas yuav ua rau tawg hauv kev kuaj ultrasonic.
Siv tau scene
Kev ua qauv ntawm seamless steel kav rau cov roj thiab cov kav dej: API 5L: GR.B (L245), X42 (L290), X46 (L320), X52 (L360), X56 (L390), X60 (L415), X65 (L450), X70 (L485). Daim ntawv thov tseem ceeb: siv los ua cov roj thiab cov kav dej ntuj. API 5L feem ntau yog hais txog lub raj xa dej steel phaj - API 5L pipeline steel phaj, lub raj xa dej steel phaj tau ua tiav rau hauv ib qho loj - txoj kab uas hla pipeline steel yeeb nkab thauj cov roj, chav thiab dej rho tawm hauv av mus rau cov chaw lag luam roj thiab roj los ntawm cov kav dej. Daim ntawv thov ntau yam ntawm API 5L pipeline steel yog maj mam nthuav dav, tshwj xeeb tshaj yog qhov zoo ntawm API 5L loj - txoj kab uas hla pipeline steel yog qhov pom tseeb dua, ua ke nrog tus nqi zoo, API 5L seamless steel yeeb nkab tau tuav txoj haujlwm tseem ceeb hauv cov kav dej steel.
