EN 10217-1 P235TR1 yog hais txog ib hom tshwj xeebkauv submerged arc welded (SSAW) steel yeeb nkabsiv rau lub hom phiaj siab. Nov yog cov ncauj lus kom ntxaws txog qhov kev xaiv no txhais li cas:
1. Txuj: EN 10217-1
Qhov no yog European tus qauv hu ua:
"Welded steel tubes rau siab lub hom phiaj - Ntu 1: Hluav taws xob welded thiab submerged arc welded tsis yog-alloy steel tubes nrog rau qhov ntsuas kub hauv chav"
Nws npog cov welded steel raj tsim rau kev siv siab, nrog rau cov kev xav tau ntawm cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, kev sim, thiab tshuaj xyuas.
2. Steel Qib: P235TR1
P235- Qhia qhovyam tsawg kawg nkaus yield zogntawm chav tsev kub (235 MPa).
TR 1- Sawv rau"Tube Quality 1", tsis yog- alloy steel qib npaj rau cov raj.
TR1 feem ntau tau teev cov tshuaj muaj pes tsawg leeg (C, Mn, Si, P, S txwv) thiab cov khoom siv kho tshuab haum rau vuam thiab sib sau.
Nws yog feem ntau siv rau kev siv siab ntawm qhov kub thiab txias nruab nrab.
3. Txheej txheem tsim khoom: Kauv Submerged Arc Vuam (SSAW)
Kauv (helical) seam- Lub steel sawb los yog phaj yog coiled kauv thiab welded raws seam.
Submerged Arc Welding (SAW)- Cov txheej txheem welding siv cov txheej txheem granular uas npog cov arc thiab weld cheeb tsam, kom ntseeg tau qhov tob tob, zoo, thiab du weld hlaws.
Txoj kev no tso cai rau cov kab loj loj los ntawm cov phaj nqaim lossis coils.
4. Cov ntawv thov ib txwm
Cov kav dej thiab cov kav dej khib nyiab
Roj thiab roj tsheb thauj mus los (tsis yog- kev pabcuam qaub tshwj tsis yog kho tshwj xeeb)
Kev siv cov qauv (piling, txhawb nqa)
Tsawg mus rau nruab nrab siab industrial piping systems
5. Cov Lus Qhia Tseem Ceeb (EN 10217-1 rau P235TR1)
Tshuaj muaj pes tsawg leeg(max%):
Cov pa roj carbon (C): ~ 0.16%
Manganese (Mn): 0.80–1.20%
Phosphorus (P): Tsawg dua lossis sib npaug rau 0.025%
Sulfur (S): Tsawg dua lossis sib npaug rau 0.020%
Mechanical zogntawm chav sov:
Yield zog (ReH): Ntau dua lossis sib npaug li 235 MPa
Tensile zog (Rm): 360-510 MPa
Elongation: Ntau dua lossis sib npaug li 25% (nyob ntawm qhov tuab)
Kev ntsuas siab(hydrostatic lossis nondestructive electric test) yog qhov yuav tsum tau ua.
Tsis yog -kev kuaj kev puas tsuajqhov yuav tsum tau muaj cov vuam seam (ultrasonic los yog radiographic kuaj rau SAW kav, nyob ntawm daim ntawv thov chav kawm).
6. Qhov zoo ntawm SSAW Pipes
Tus nqi -zoo rau cov kab loj loj (feem ntau yog los ntawm 20 ntiv mus txog 100 ntiv tes lossis ntau dua).
Yuav ua tau nyob rau hauv ntev ntev, txo cov pob qij txha.
Qhov zoo ntawm qhov yooj yim (inch thiab phab ntsa thickness kho los ntawm spiraling lub kaum sab xis thiab phaj dav).
7. Sib piv nrog Longitudinal SAW (LSAW)
SSAWmuaj kauv weld, uas tuaj yeem faib kev ntxhov siab sib txawv; qee qhov tshwj xeeb txwv tsis pub muab kauv vuam kav rau siab -siab hydrocarbon kev pabcuam tshwj tsis yog kuaj ntau.
LSAW(Longitudinal) muaj ib txoj hlua ncaj nraim, feem ntau nyiam rau siab - cov ntawv thov tseem ceeb, tab sis txoj kab uas hla yuav raug txwv los ntawm phaj dav.
Yog koj yogprocuring los yog tsim nrogTS EN 10217-1 P235TR1 SSAW kav, xyuas kom meej tias:
Cov chaw tsim khoom tau lees paub rau EN 10217-1.
Cov kev xav tau ntxiv (yog tias muaj) tau teev tseg rau koj cov kev pabcuam (xws li, kev ntsuas kev cuam tshuam ntawm qhov kub qis, HIC tsis kam rau ntub H₂S kev pabcuam).
Cov yeeb nkab yog muab nrog cov ntawv pov thawj kev xeem (EN 10204 Hom 3.1 lossis 3.2).
Koj xav paub meej txogqhov ntev / kam rau ua(EN 10217-1),painting / txheej xaiv, los yogKev sib piv nrog API 5L qib?
