Waterproof thiab Sealing Performance ntawm API 5L X52 Pipelines
Waterproof kev ua tau zoo ntawmAPI 5L Qib X52 (L360)cov kav xa dej yog qhov tseem ceeb rau kev ua haujlwm ntev -kev nyab xeeb, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig faus lossis subsea. Tiv thaiv cov dej nkag ntawm cov pob qij txha thiab los ntawm cov yeeb nkab phab ntsa yog qhov tseem ceeb kom tsis txhob muaj kev cuam tshuam sab hauv thiab sab nraud uas tuaj yeem ua rau cov txheej txheem degradation thiab kim heev.
Precision Interface Sealing Methods
Vuam:
puv -kev nkag mus hauv qab vuam muab ib qho monolithic, xoom- leak barrier rau siab - kev pabcuam siab.
Roj hmab sealing rings:
siab -kev ua tau zoo elastomers (NBR/EPDM) muab hloov tau yooj yim waterproof seals nyob rau hauv lub qhov (socket) los yog mechanical coupling systems.
Threaded kev twb kev txuas:
precision-txiav cov xov nrog cov xov sib txuas ua kom cov dej noo- nruj haum rau cov kab hluav taws xob me me.
Advanced Anti-Corrosion thiab Moisture Barriers
3PE / FBE txheej:
ib qho impermeable polymer barrier tiv thaiv ya raws thiab av tshuaj los ntawm ncav cuag cov hlau.
Kub-dip galvanizing:
zinc- hlau alloy txheej muab kev tiv thaiv cathodic txawm tias muaj dej noo.
Internal plastic linings:
tiv thaiv lub bore los ntawm dej -induced pitting thiab scaling nyob rau hauv lub municipal kab.
Ntev -Tsev tu thiab tshuaj xyuas
Kev tswj xyuas cov dej tsis zoo yuav tsum tau teem sijhawm soj ntsuam: kuaj xyuas cov hnub so (pinhole) qhov tsis xws luag hauv cov txheej txheem sab nraud, txheeb xyuas cov cathodic tiv thaiv kev ncaj ncees, thiab pigging lub bore sab hauv los tiv thaiv cov khoom khib nyiab uas cuam tshuam cov dej noo thiab pib qhov chaw hauv zos.
Kev ntseeg siab nyob rau hauv ib puag ncig hnyav
X52 pipelines tswj kev sib khi ua haujlwm nyob rau hauv siab -siab subsea tej yam kev mob thiab nyob rau hauv cov av saturated. Kev sib xyaw ua ke siab -lub zog steel nrog ntau- txheej txheej dej tsis zoo muab cov kav dej nyab xeeb, ruaj khov rau cov roj av, roj av thiab cov dej hauv nroog thoob ntiaj teb.
Cov lus nug nquag
Puas yog X52 steel ib txwm tsis muaj dej?
Cov hlau nws tus kheej yog impermeable, tab sis nws nto rusts yog hais tias noo noo yog tam sim no tsis muaj ib tug tiv thaiv txheej los yog kev kho mob.
Kev xeem hnub so yog dab tsi?
Ib qho tsis yog -kev puas tsuaj siab- qhov ntsuas hluav taws xob hluav taws xob uas kuaj pom cov feeb qhov lossis qhov tsis sib xws hauv cov txheej txheem sab nraud.
Cov roj hmab foob puas tuaj yeem ua rau siab - siab roj?
Yog lawm, yog tias lub elastomer (xws li, nitrile) yog hydrocarbon - tau tshaj thiab ntsuas rau kev khiav hauj lwm siab thiab kub.
Puas yog galvanizing txhim kho kev tiv thaiv dej?
Nws muab cov khoom siv hlau ruaj ruaj tiv thaiv xeb ntawm kev sib cuag nrog dej, zoo waterproofing lub neej ntawm cov hlau.
Yuav ua li cas yog qhov dej xau hauv faus X52 yeeb nkab kho?
Cov dej me me tuaj yeem siv cov clamps tshwj xeeb; tseem ceeb tsis ua hauj lwm yuav tsum tau khawb thiab hloov cov seem nrog ib tug tshiab welded thiab coated sib koom ua ke.
