Nyob rau hauv lub ntiaj teb loj thiab complex ntawm kev lag luam piping, kev nkag siab txog ntau hom steel kav thiab lawv cov yam ntxwv tshwj xeeb yog qhov tseem ceeb rau kev ua tiav qhov project. Ntawm ntau txoj kev tsim khoom, High-Frequency Welded (HFW) steel yeeb nkab sawv tawm raws li kev siv dav thiab kev ntseeg siab heev. Tab sis dab tsi yog HFW steel yeeb nkab? Kab lus no yog npaj los muab cov lus qhia dav dav rau HFW steel kav, qhia txog lawv cov txheej txheem tsim khoom, cov ntsiab lus tseem ceeb, thiab cov qauv thoob ntiaj teb uas tswj hwm lawv qhov zoo thiab daim ntawv thov. Hebei Huayang Steel Pipe Co., Ltd., cov chaw tsim khoom lag luam, muaj kev nkag siab txog cov khoom tseem ceeb no.
TxhaisSiab -Frequency Welded (HFW) Steel Pipe
HFW steel yeeb nkab yog ib hom Electric Resistance Welded (ERW) yeeb nkab uas siv siab - zaus tam sim no los ua kom sov rau vuam. Cov txheej txheem pib nrog lub tiaj tiaj steel sawb (coil) uas tau tsim ua rau hauv qhov qhib - seam cylindrical zoo li. Raws li cov npoo ntawm cov sawb sib sib zog nqus, qhov siab - zaus hloov tam sim no yog siv, tsim kom muaj cua sov hauv cheeb tsam ntawm cov npoo. Nyob rau tib lub sijhawm, kev siv tshuab siab los ntawm nyem cov chais ua rau cov npoo cua sov ua ke, tsim kom muaj cov khoom siv- xeev forge weld yam tsis muaj qhov sib ntxiv ntawm cov hlau. Qhov no ua rau muaj kev huv, muaj zog, thiab homogeneous weld seam nrog lub tshav kub tsawg heev - thaj chaw cuam tshuam (HAZ).
Cov yam ntxwv tseem ceeb uas txhais HFW steel yeeb nkab suav nrog:
•Longitudinal Weld Seam: Ib leeg, ncaj weld khiav raws qhov ntev ntawm cov yeeb nkab.
•Solid-Lub Xeev Vuam: Cov npoo yog rhuab mus rau lub xeev yas thiab forged ua ke, tsis yaj.
•High-Frequency Current: Kev siv siab- zaus tam sim no ua kom ceev ceev, thaj chaw cua sov thiab nqaim HAZ.
•Nruam ntau lawm: Ua los ntawm cov coils, tso cai rau kom ua tau zoo, siab -ceev ntau lawm.
HFW Manufacturing Process nyob rau hauv nthuav dav
Kev tsim cov HFW steel yeeb nkab yog cov txheej txheem ua haujlwm siab thiab meej:
1.Coil Kev Npaj: Hlau coils yog uncoiled, flattened, thiab lawv cov npoo yog trimmed los xyuas kom meej uniformity. Cov coils ua tiav yog welded kawg - mus rau - kawg los tsim ib txoj hlua txuas ntxiv.
2.Forming: Cov kab nrib txuas txuas ntxiv dhau los ntawm kev sib sau ua ke uas maj mam ua rau hauv qhov qhib - seam tube.
3.High-Vuam zaus: Siab- zaus tam sim no yog induced rau hauv cov npoo ntawm lub raj qhib, cua sov sai sai. Squeeze rollers ces siv siab, forging cov npoo ua ke los tsim cov vuam. Cov khoom siv ntau dhau (flash) raug txiav tam sim ntawd.
4.Sizing thiab Straightening: Cov yeeb nkab welded yog tom qab ntawd loj rau nws qhov kawg sab nraud txoj kab uas hla thiab ncaj nraim kom tau raws li qhov ntev ntev.
5.Non-Kev Ntsuam Xyuas Kev Puas Tsuaj (NDT): Kev kuaj xyuas qhov tseem ceeb, xws li kuaj ultrasonic (UT) ntawm cov vuam seam, tau ua hauv online txhawm rau txheeb xyuas qhov tsis zoo sab hauv lossis sab nraud.
6.Cutting thiab Finishing: Cov yeeb nkab yog txiav mus rau qhov ntev ntev, thiab xaus yog beveled los yog threaded raws li xav tau. Cov txheej txheem xaiv tau zoo li kev kho cua sov thiab txheej txheej (xws li 3LPE, FBE) raug siv.
Cov Ntsiab Lus Qhia thiab Cov Qauv rau HFW Steel Pipes
HFW steel kav yog tsim los ua kom tau raws li ntau yam kev cai thoob ntiaj teb, ua kom lawv haum rau ntau hom kev siv thiab lav qhov zoo thiab kev ua haujlwm. Lub ntsiab specifications muaj xws li:
1. API 5L(American Petroleum Institute Specification rau Kab Yeeb)
Qhov no yog ib qho ntawm cov qauv tseem ceeb tshaj plaws rau HFW kav dej siv hauv kev lag luam roj thiab roj. API 5L qhia txog qhov yuav tsum tau ua rau kev tsim khoom ntawm ob theem kev qhia tshwj xeeb (PSL1 thiab PSL2) ntawm seamless thiab welded steel kav siv rau hauv cov kav dej thauj mus los hauv kev lag luam roj av thiab roj av. Nws suav nrog ntau qib (piv txwv li, Gr.B, X42, X52, X60, X70, X80) thiab txhais cov khoom siv kho tshuab, tshuaj lom neeg muaj pes tsawg leeg, thiab kev xeem cov cai.
2. ASTM Cov Qauv (American Society for Testing and Materials)
Ob peb tus qauv ASTM siv rau HFW kav dej, nyob ntawm seb lawv xav siv:
•ASTM A53: Npog seamless thiab welded dub thiab kub -dipped galvanized steel kav rau kev siv zoo tib yam hauv dej, roj, thiab cua kab.
•ASTM A106: Feem ntau yog seamless carbon steel yeeb nkab rau siab - qhov kev pab kub, tab sis HFW kav yuav siv tau rau cov ntawv zoo sib xws yog tias tau teev tseg.
•ASTM A252: Qhia meej welded thiab seamless steel yeeb nkab pawg.
•ASTM A500: Npog txias - ua welded thiab seamless carbon steel structural tubing nyob rau hauv rounds thiab duab.
3. EN Standards (European Norms)
Cov qauv European tau txais kev pom zoo thoob ntiaj teb:
TS EN 10217: Welded steel raj rau lub hom phiaj siab. Ntu 1 suav nrog cov hlau tsis yog- alloy steel tubs nrog cov khoom tshwj xeeb hauv chav tsev kub, thiab Ntu 2 npog cov hlau tsis yog- alloy thiab alloy steel raj nrog cov khoom ntsuas kub siab.
