KHOOM
Tianjin Brisk Steeltsom rau cov khoom tsim thiab muab cov seem hollow thiab steel yeeb nkab
Hom kev tsim khoom
- Cov qauv rau ERW cov yeeb nkab yuav tsum muaj qhov sib txawv ntawm qhov sib txuas, thiab kev ntxhov siab- kev tshem tawm ntawm qhov vuam seam feem ntau yuav tsum tau ua rau cov khoom siv qib B.
- Scope yog muab faib ua ob pawg loj:ERW cov qauv rau kev thauj cov kua dej(yuav tsum tau hydrostatic leak-tightness test for medium conveyance) thiabERW cov qauv rau kev siv cov qauv(tsom mus rau txhua yam muaj zog thiab khoov / flattening kev ua tau zoo; siv nyob rau hauv siab yog nruj me ntsis txwv tsis pub).
ERW PROCESS
ASTM Cov Qauv rau ERW Siab Piping (rau Dej, Roj thiab Tiv Thaiv Hluav Taws Xob)
ASTM A53 / A53M (Lub ntiaj teb no hom ERW yeeb nkab rau qis - kev pabcuam kua dej siab; siab tshaj qhov ntim khoom xa tuaj)
- Npog ob leeg seamless thiab welded kav: "Hom E" tshwj xeeb yog hais txog ERW (Electric Resistance Welded) yeeb nkab. Qhov ntau thiab tsawg yog los ntawmNPS 1/8 to NPS 24, nrog phab ntsa thicknesses txuam ASME B36.10Teem caij 40 thiab 80.
- Adaim ntawv thovsuav nrog cov khoom siv dej thiab tso dej, kev faib hluav taws xob hauv nroog, qis-sab siab, cov kab thaiv hluav taws, thiab cov khoom siv hlau dav dav.
- Muaj cov xwm txheej khoom xa tuaj:Dub yeeb nkab thiab Kub-Dip Galvanized (HDG).
- Yam yuav tsum tau kuaj:Kev sim hydrostatic (tag nrho-ntev dej siab ntsuas ntsuas rau 5 vib nas this uas tsis muaj qhov xau), kev sim tiaj tus, thiab ntsuas qhov ntsuas tam sim no ntawm cov vuam seam; cov kav dej nrog NPS Tsawg dua lossis sib npaug ntawm 2 yuav tsum dhau 90℃txias dabtsi yog khoov kuaj; threading, grooving, thiab flange ua cov kev pabcuam muaj.
- Xav paub ntau ntxiv, thov niasASTM A53.
ASTM A795 / A795M Galvanized ERW Yeeb Nkab rau Hluav Taws Sprinkler Systems
- Tus qauv tsim nyog rau cov phiaj xwm tiv thaiv hluav taws hauv North America, sib haum nrog UL / FM daim ntawv pov thawj cov cai.
- Kev tsim khoom raug txwv rau kub-dip galvanized ERW puag ncig cov yeeb nkab, haum rau ntub- thiab qhuav- cov kav dej tua hluav taws. Cov khoom siv kho tshuab ua ke nrog ASTM A53 Qib B; hluav taws tshwj xeeb- kev nyab xeeb yuav tsum tau siv rau galvanizing adhesion thiab huv si, thiab tsis tso cai rau kev muab cov yeeb nkab dub liab qab.
ASTM Cov Qauv rau ERW Cov Hlau Yeeb Nkab (Kev Tsim Kho HSS)
ASTM A500 / A500M
- Tshooj:Round, square, thiab rectangular tubing (HSS)
- Cov qhab nia(Gr. B thiab Gr. C feem ntau stocked rau export)
- Ua raws li kev sib tw, tensile, thiab dabtsi yog khoov; tsis tas yuav tsum tau kuaj hydrostatic siab.Sab nraud txoj kab uas hla yog ± 1%, thiab phab ntsa thickness kam rau ua yog ± 12.5%.Nws muaj kev sib raug zoo zoo nrog kub -dip galvanizing, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim qauv steel txawv teb chaws.
ASTM A501/A501M Kub{2}}Tsim ERW Cov Tubing
- Tsim los ntawm vuam siv kub- dov puag khoom; haum rau kub dabtsi yog khoov, kub-dip galvanizing, thiab siab - kub forging. Feem ntau siv rau kev thauj khoom-cov kabmob txuas txuas thiab hnyav-cov haujlwm steel qauv kab.
Standard Test System rau ERW Yeeb Nkab
- Tshuaj ntsuam xyuas:Thaum tshav kub kub tsom xam ntxiv rau ua tiav- cov khoom kuaj xyuas; tswj cov khoom tsis zoo (C, Mn, S, P)
- Mechanical Testing:Tensile xeem (yield zog, tensile zog, elongation), flattening xeem (tsis muaj weld tawg los yog delamination), rov qab flattening xeem, thiab khoov xeem
- Weld NDT (Tsis yog-Kev Ntsuas Kev Ntsuas):Eddy Tam sim no (ET), Ultrasonic (UT), thiab Sib Nqus Flux Leakage (MFL); tus nqi piv txwv siab dua rau cov kua dej- cov kav dej
- Kev Ntsuas Hydrostatic:Yuav tsum tau tsuas yog rau cov kua dej- cov qauv kev pabcuam; tsis tas rau cov qauv -qib kav
- Dimensional Verification:Kev tshuaj xyuas tag nrho ntawm sab nraud txoj kab uas hla, phab ntsa thickness, ntev, ncaj, thiab kawg -fab squareness
- Kev kho deg:Anti- xeb roj, xim dub, kua roj vanish, thiab kub-dip galvanizing (tus qauv zinc txheej: 70-85 μm)
Cov lus nug nquag nug (FAQ)
Q: ASTM A500 HSS cov kav dej puas tuaj yeem siv rau kev thauj mus los hauv dej lossis roj?
A: Tsis pom zoo. A500 yog tsim los rau cov qauv kev coj tus kheej yam tsis muaj kev tshuaj xyuas hydrostatic. Cov kev pheej hmoo zais zais yuav muaj nyob rau hauv nruab nrab siab; xaiv ASTM A53 Gr.B ERW yeeb nkab rau cov dej xa mus.
Q: Koj puas ERW weld seams xav tau kev kho cua sov?
A: A53, A500 txais yuav online weld leveling kev kho mob los lav qhov kev ncaj ncees ntawm vuam yam tsis tas yuav tsum tau tshaj tawm -weld heat treatment.
Q: Dab tsi nto tiav koj tuaj yeem muab rau ASTM ERW steel kav?
A: Dub liab qab yeeb nkab nrog anti- xeb roj, pleev xim dub, kua roj vanish coated, kub-dip galvanized (HDG, 70-85μm zinc txheej txheem).
Q: Ua raws li txoj cai ASTM ERW tus qauv rau kuv qhov project yooj yim?
A: Dej / roj pipeline → A53 Gr.B; Hluav taws kub sprinkler system → A795 galvanized ERW; Rhiav & chaw nres tsheb npav steel ncej → A500 Gr.B/C HSS; Lub hauv paus steel ncej → A252.
