ERW L235 steel yeeb nkab
ERW tube yog dab tsi?
Hluav taws xob tsis kam welded (ERW) yeeb nkab yog tsim los ntawm steel kauj thiab vuam seam khiav mus rau tib lub yeeb nkab. Qhov dav ntawm lub kauj yog tib yam li qhov ncig ntawm cov yeeb nkab yog li txoj kab uas hla yog txwv rau 24 ntiv tes.
Qhov muaj pes tsawg leeg ntawm L235 yog dab tsi?
EN 10224 Qib L235 Carbon Steel Seamless Tubes yog tsim los ntawm cov pa roj carbon tsawg nrog 0.17% carbon cov ntsiab lus nyob rau hauv muaj pes tsawg leeg nrog rau 0.12% manganese.
Txoj kev sib txuas ntawm L235 ncaj seam steel yeeb nkab feem ntau yog siv vuam, xov txuas lossis flange txuas. Ntawm lawv, kev sib txuas welded muaj lub zog siab thiab kev sib khi, thiab tsim nyog rau lub sijhawm muaj kev sib txuas siab; threaded kev twb kev txuas yog yooj yim rau nruab thiab disassemble, thiab yog haum rau ib ntus los yog nquag hloov zaus; Kev sib txuas flange Haum rau lub sijhawm uas yuav tsum tau ceev installation thiab disassembly.
