Dab tsi yog High -Frequency Welded (HFW) Steel Pipe?
Siab - zaus welded (HFW) steel yeeb nkabyog tsim los ntawm kev siv siab - zaus hloov tam sim no (feem ntau100-500 kHz) mus rau cov npoo ntawm qhov txias - ua steel sawb. Ob lub cev tshwm sim - tustawv nqaij nyhuv, uas concentrates tam sim no nyob rau saum npoo, thiab covkev sib thooj, uas concentrates nws ntawm cov npoo uas nyob ib sab - cua sov cov npoo rau forging kub. Extrusion rollers ces forge lawv ua ke, tsim ib tug ncaj- seam weld muaj zog li lub hauv paus hlau tsis muaj cov khoom muab tub lim.
Cov yam ntxwv tseem ceeb
Kev ntseeg tau zoo:
automated tsis thiab online ultrasonic NDT kom zoo ib yam weld nkag.
High efficiency:
Kev tsim khoom tas mus li txhawb nqa loj - cov phiaj xwm hluav taws xob thiab kev tsim kho vaj tse.
Economic tus nqi:
tus nqi tsim khoom qis dua li lub zog-ntaus seamless tho.
Nto zoo:
nqaim thaum tshav kub kub- thaj chaw cuam tshuam thiab me me spatter ua kom huv si.
Txoj Kev Taug Kev Manufacturing
Sawb txoj kev:
txias- los yog kub- ua cov chais ua cov hlua rau hauv lub tog raj kheej.
High - zaus vuam:
cov npoo yog rhuab thiab fused nyob rau hauv extrusion siab.
Tswj cua txias:
huab cua los yog dej txias teeb lub hom phiaj hardness thiab grain qauv.
Sizing thiab txiav:
precision rollers teem kawg OD; cov yeeb nkab yog txiav kom ntev.
Quality Assurance thiab Standards
Txhua HFW sib koom ua ke dhau los kuaj hydrostatic ntawm 1.5x tsim siab thiab 100% kev tshuaj xyuas ultrasonic ntawm vuam seam. Cov qauv xws li API SPEC 5L thiab ISO 3183 tswj kev ua haujlwm ntawm metallurgical thiab kev ncaj ncees. Rau kev pabcuam roj tseem ceeb, PSL2 HFW yeeb nkab nrogseam normalizing
- ib qho kev kho cua sov hauv cheeb tsam uas ua kom zoo dua cov weld-zone grain qauv - matches lub toughness ntawm seamless yeeb nkab.
Daim ntawv thov
Onshore roj sib sau ua ke thiab natural gas faib mains (txog API 5L X70)
Cov kab ke, choj ncej thiab scaffolding
Siab - cov kav dej siab thiab hauv cheeb tsam cua sov manifolds
Precision tubing rau automotive ntas thiab mechanical rollers
Cov lus nug nquag
Vim li cas HFW hu ua muab tub lim - vuam dawb?
Lub hauv paus hlau nws tus kheej kuj heats cov npoo, uas yog forged ua ke; tsis muaj lwm cov hlau lossis electrode ntxiv.
Puas yog HFW muaj kev nyab xeeb zoo li seamless rau cov pa roj ntsha?
Yog lawm. PSL2 HFW yeeb nkab nrog seam normalizing phim cov neeg kho tshuab toughness thiab kev ntseeg siab ntawm seamless rau kev pabcuam roj.
Dab tsi yog seam normalizing?
Kev kho cua sov hauv cheeb tsam uas ua kom zoo dua cov weld-zone grain qauv, tshem tawm kev ntxhov siab thiab brittleness los ntawm kev txias sai tom qab vuam.
Qhov siab tshaj plaws txoj kab uas hla rau HFW yeeb nkab yog dab tsi?
HFW yog qhov ua tau zoo tshaj plaws txog li 24-26 ntiv tes; loj diameters siv submerged arc vuam (LSAW/SSAW).
Puas yog qhov siab - zaus tam sim no nkag mus rau tag nrho phab ntsa?
Tam sim no concentrates ntawm cov npoo, tab sis extrusion siab ua kom sov thiab fusion ncav cuag 100% ntawm phab ntsa kom nkag mus rau tag nrho.
Cov qib twg tuaj yeem tsim ua HFW yeeb nkab?
HFW yeeb nkab yog tsim nyob rau hauv API 5L qib los ntawm Qib B mus txog X80 thiab sib piv ISO 3183 L-designations; qib siab dua - zog PSL2 feem ntau yuav tsum tau seam normalizing los lav weld-zone toughness.
