P265TR1 SSAW STEEL YEE: Kev Tshwj Xeeb Cov Lus Qhia thiab Txheej txheem cej luam
Khoom:P265TR1 YEEB NKAB
Txheej txheem tsim khoom:Ssaw (kauv submerged arc vuam)
1. Pib
P265TR1 SSAW STEEL YEE YEE yog ib hom ntawm welded steel hlau tsim los siv kauv submerged arc vuam txheej txheem. Kev tsim qauv "P265TR1" yog muab tau los ntawm European txheemRau 10219(Khaub thuas tsim Welded cov qauv Hollow ntawm tsis - nplej enloy rau cold- Tsim welded cov txheej txheem hollow.
"P"sawv rau "siab" lossis "qauv" daim ntawv thov.
"265"qhia txog tusYam tsawg kawg nkaus paib zog (RH)Ntawm cov hlau hauv MPA (265 MPa lossis ~ 265 N / MMOL).
"TR"sawv rau"Tube".
"1"Yog hais txog cov khoom xa tuaj, uas yog feem ntau yog "raws li welded" rau ssaw kav.
These pipes are primarily used in structural applications such as building frames, bridges, pylons, and other supporting structures, as well as for low-pressure fluid transmission.
2. Cov yam ntxwv tseem ceeb ntawm ssaw kav
Muab kauv seam kauv:Weld leeg khiav hauv lub helix ib ncig ntawm cov yeeb nkab nruab nrab ntawm ib ncig. Qhov no tso cai rau kev tsim cov diam hlua loj los ntawm cov phaj nqaim lossis cov hlua.
Lub zog siab:Tus qauv weld tuaj yeem faib cov kev ntxhov siab ntau dua li ntawm cov yeeb nkab piv rau txoj kev ncaj ncees mus rau txoj kev ntxhov siab ncaj qha rau kev ntxhov siab.
Yooj nyob rau hauv sizing:SSAW cov txheej txheem yog kev yoog tau heev thiab tuaj yeem tsim ntau yam diameters siv tib qho dav ntawm cov hlau sawb, tsuas yog hloov kho lub kaum sab xis.
Tus nqi -} Siv tau zoo rau txoj kab uas loj loj loj:Nws yog feem ntau cov nyiaj txiag ntau dua los ua kom loj- txoj hauj lwm uas hla uas siv SSW txoj kev siv.

4. Cov lus tseem ceeb
Qauv:Thaum EN 10219 yog ib qho siv tau, cov kav dej no tseem tuaj yeem tsim rau lwm cov qauv hauv ntiaj teb xws li cov qauv yeeb nkab) lossis rau piling), uas yuav muaj cov qauv kev sib txawv thiab cov khoom siv neeg kho mob.
Ntawv pov thawj:Cov kav dej yuav tsum tau muab rau ibMill xeem Daim Ntawv Pov Thawj (MTC)lossisDaim Ntawv Pov Thawj Kuaj Xyuas 3.1Raws li en 10204, uas qhia tseeb tias cov khoom ua raws li cov kev cai xaj kom ua thiab tus qauv tshwj xeeb.
Kev thev:Qhov loj me (OD, WT, Ntev, Ncaj Nrees) yog cov kev tsim kom muaj kev zam uas yog txhais hauv tus qauv (piv txwv li, en 10219-2).
Tham cov chaw tsim tshuaj paus:Rau cov phiaj xwm tseem ceeb, ib txwm sab laj cov chaw tsim khoom rau cov kev ntsuas tseeb, cov txheej txheem sim, thiab haum rau cov ntawv thov.
