Cov kav hlau muaj ntau hom thiab ntau qhov loj. Cov kav hlau tsis muaj qhov sib txuas yog cov kev xaiv uas tsis tau vuam, ua los ntawm cov hlau billet uas tau hollowed. Thaum nws los txog rau cov kav hlau vuam, muaj peb txoj kev xaiv: ERW, LSAW thiab SSAW.
Cov kav dej ERW yog ua los ntawm cov hlau tsis kam welded. Cov kav dej LSAW yog ua los ntawm cov hlau longitudinal submerged arc welded. Cov kav dej SSAW yog ua los ntawm cov hlau spiral submerged arc welded.
Cia peb los saib ze dua txog txhua hom yeeb nkab, piv lawv qhov sib txawv, thiab yuav siv cov lus piav qhia kom raug li cas.
Cov yeeb nkab hlau tsis muaj qhov txuas
Lub raj xa dej seamless yog ua los ntawm cov hlau tsis xeb, uas raug cua sov thiab perforated los ua ib lub voj voog hollow seem. Vim tias cov yeeb nkab seamless tsis muaj thaj chaw vuam, nws suav tias muaj zog dua li cov yeeb nkab vuam thiab tsis yooj yim rau xeb, yaig thiab kev puas tsuaj dav dav.
Txawm li cas los xij, tus nqi ib tuj ntawm cov yeeb nkab seamless yog 25-40% siab dua li ntawm cov yeeb nkab ERW. Cov yeeb nkab hlau seamless qhov ntau thiab tsawg yog txij li 1/8 nti txog 36 nti.
Kev vuam tsis kam (ERW) yeeb nkab
ERW (kev vuam tsis kam) cov yeeb nkab hlau yog tsim los ntawm kev dov hlau rau hauv cov yeeb nkab thiab txuas ob kawg nrog ob lub electrodes tooj liab. Cov electrodes no yog disc-puab thiab tig thaum cov khoom hla ntawm lawv. Qhov no tso cai rau lub electrode kom tswj tau kev sib cuag tas mus li nrog cov khoom siv rau lub sijhawm ntev ntawm kev vuam tas mus li. Kev nce qib ntawm cov thev naus laus zis vuam txuas ntxiv txhim kho cov txheej txheem no.
Cov yeeb nkab ERW yog ib qho kev hloov pauv pheej yig thiab zoo rau cov yeeb nkab hlau tsis muaj seamless, uas ruaj dua li cov yeeb nkab SAW. Piv nrog rau cov txheej txheem solvent siv hauv cov yeeb nkab submerged arc welded, qhov tsis zoo kuj tsis tshua muaj tshwm sim, thiab qhov tsis zoo ntawm qhov vuam ncaj qha tuaj yeem pom tau yooj yim los ntawm kev cuam tshuam ultrasonic lossis pom.
Lub txoj kab uas hla ntawm ERW yeeb nkab yog txij li nti (15 hli) mus txog 24 nti (21.34 hli).
Cov yeeb nkab uas tau muab dej ntws los ntawm cov kav dej
LSAW (kev vuam ncaj) thiab SSAW (kev vuam kauv) yog cov kev hloov pauv ntawm cov yeeb nkab vuam hauv qab dej. Cov txheej txheem vuam hauv qab dej tsim cov hluav taws xob ceev ceev kom tiv thaiv kev kub hnyiab sai ntawm cov txheej flux thiab ua rau muaj kev sib sau ua ke hauv thaj chaw vuam.
Qhov sib txawv tseem ceeb ntawm cov kav dej LSAW thiab SSAW yog qhov kev taw qhia ntawm qhov vuam, uas yuav cuam tshuam rau lub peev xwm dais siab thiab qhov yooj yim ntawm kev tsim khoom. LSAW siv rau cov ntawv thov hluav taws xob nruab nrab mus rau qhov siab, thiab SSAW siv rau cov ntawv thov hluav taws xob qis. Cov kav dej LSAW kim dua cov kav dej SSAW.
Cov yeeb nkab longitudinal submerged arc welded
Cov yeeb nkab LSAW yog ua los ntawm kev ua cov pwm hlau kub dov rau hauv lub tog raj kheej thiab txuas ob qho kawg ua ke los ntawm kev vuam kab. Qhov no tsim cov yeeb nkab vuam ntev. Cov yeeb nkab no feem ntau yog siv rau cov yeeb nkab xa mus ntev ntawm roj, roj av, cov thee ua kua, cov roj hydrocarbons, thiab lwm yam.
Muaj ob hom yeeb nkab LSAW: ib txoj kab ntev thiab ob txoj kab (DSAW). Cov yeeb nkab hlau LSAW sib tw nrog cov yeeb nkab hlau tsis muaj kab thiab cov yeeb nkab hlau ERW 16 txog 24 nti. Hauv kev lag luam roj thiab roj av, cov yeeb nkab loj API 5L LSAW siv rau kev thauj mus los ntev thiab zoo ntawm cov hydrocarbons.
Feem ntau, txoj kab uas hla ntawm cov yeeb nkab LAW yog nruab nrab ntawm 16 nti thiab 60 nti (406 mm thiab 1500 mm).
Tsis muaj qhov tsis sib xws - cov khoom tawg uas tshuav ntawm kev ua tsov rog - kev vuam arc longitudinal submerged - kev vuam arc spiral submerged - pipeline - kev vuam arc spiral submerged
SSAW yeeb nkab
Cov yeeb nkab SSAW yog tsim los ntawm kev dov thiab vuam cov hlau strips hauv qhov kev taw qhia kauv lossis kauv kom ua rau qhov vuam ua kauv. Cov txheej txheem vuam kauv ua rau nws muaj peev xwm tsim cov khoom loj. Cov yeeb nkab hlau kauv feem ntau yog siv rau kev xa cov kua dej siab qis, xws li cov kav dej hauv cov platforms hauv hiav txwv, cov chaw tsim khoom petrochemical lossis cov chaw tsim khoom nkoj, nrog rau cov tsev pej xeem thiab kev teeb tsa piling.
Cov yeeb nkab txoj kab uas hla ntawm SSAW feem ntau yog 20 nti txog 100 nti (406 hli txog 25040 hli).
Yuav ua li cas thiaj li xaj tau cov kav hlau rau koj qhov project
Thaum xaj cov yeeb nkab hlau, muaj ob qhov loj tseem ceeb: qhov loj ntawm cov yeeb nkab nominal (NPS) thiab phab ntsa tuab (schedule). Rau cov yeeb nkab tsawg dua 4 nti, qhov ntev ntawm cov yeeb nkab tuaj yeem yog ib qho random (SRL) 5-7 meters, lossis rau cov yeeb nkab ntau dua 4 nti, qhov ntev ntawm cov yeeb nkab tuaj yeem yog ob npaug random (DRL) 11-13 meters. Muaj qhov ntev tshwj xeeb rau cov yeeb nkab ntev. Cov kawg ntawm cov yeeb nkab tuaj yeem yog bevel (be), plane (pe), thread (THD) thread thiab coupling (T&C) lossis groove.
Cov ntsiab lus ntawm cov lus qhia txog kev txiav txim ib txwm muaj:
Hom (seamless los yog welded)
Qhov loj ntawm cov yeeb nkab nominal
Teem sijhawm
Hom kawg
Qib khoom siv
Tus nqi hauv meters lossis ko taw lossis tons.
