9. Seamless steel yeeb nkab GB / T8162-1999, steel tooj: 10 #, 20 #, 35 #, 45 # thiab 16Mn
(Q345), Specification: 6-720 * 1-70mm
10. Seamless steel yeeb nkab rau conveying kua GB / T8163-1999, steel tooj: 10 #, 20 #, 16Mn (Q345),
Specifications: 6-720 * 1-70mm
11. Tsawg-nruab nrab siab boiler raj GB3087-1999, steel No.: 10 #, 20 #, specification: 6-720 * 1-70mm
12. High-pressure boiler yeeb nkab GB5310-1995, steel No.: 20G, specification: 6-720 * 1-70mm.
"thiab" DN "-zoo li yog siv los qhia txoj kab uas hla, qhov txawv yog:
"" khij txoj kab uas hla ntawm lub voj voog zoo tib yam, lossis sab nraud ntawm cov yeeb nkab sib npaug los ntawm cov phab ntsa tuab, xws li: φ25 × 3 kos lub taub sab nraud
Cov yeeb nkab ntawm 25mm thiab 3mm phab ntsa thickness;"DN": lub npe nominal rau fittings xws li cov kav dej thiab li qub
Txoj kev, feem ntau yog ze rau lub puab kab.
Nws txhais tau hais tias sab nraud txoj kab uas hla, thiab DN yog hais txog lub puab kab uas hla DN: nominal txoj kab uas hla: txheej kab.
Tam sim no cov tub- -.zoo li yog nyob rau hauv nti, millimeters tsuas yog ib tug ntau approximate, yooj yim rau nco ntsoov tus naj npawb.
Piv txwv li, DN50 yeeb nkab yuav tsum yog 2 nti, 1 nti = 25.4mm, 2 nti yuav tsum yog 50mm,
Lub sijhawm no, cov phab ntsa tuab ntawm cov yeeb nkab, cov kav dej kauv yog siab dua 5 hli, siv 5 hli ua piv txwv,
Sab nraud txoj kab uas hla ntawm DN50 raj yuav tsum yog li 60 hli.
Q345 seamless steel yeeb nkab yog ib hom steel yeeb nkab khoom.Q stands rau yield ntawm cov khoom no,
Nws yog thawj tsab ntawv ntawm tus pinyin, ua raws li tus lej 345, uas yog hais txog tus nqi ntawm cov khoom siv no.
Thaum los yog ib ncig ntawm 345.Thiab txo tus lej raws li cov thickness ntawm cov khoom nce.
Cov chav kawm zoo sib xws rau txoj kev naming rau Q235 chav kawm.
Q345A, Q345B, Q345C, Q345D, Q345E.Qhov no yog qhov sib txawv ntawm cov qib, sawv cev los ntawm
Feem ntau, yog qhov cuam tshuam ntawm qhov kub thiab txias!
Q345A, tsis muaj kev cuam tshuam;Q345B, 20 degrees kub cuam tshuam;q345c 0
Qib cuam tshuam;Q345D qib, yog 20 degree cuam tshuam;Q345E theem, yog-40 degree cuam tshuam
Qhov cuam tshuam kub, qhov cuam tshuam tus nqi kuj txawv..
Nyob rau hauv lub phaj, nws yog ib tug low-alloy series.Ntawm cov khoom uas tsis tshua muaj alloy, cov khoom no yog cov feem ntau.
Q345 seamless steel yeeb nkab yav dhau los hu ua: 16Mn seamless steel yeeb nkab.
Tus qauv siv sab nraud ntawm Q345 seamless steel yeeb nkab yog: GB709, thiab cov qauv siv sab hauv yog:
GB/T1591-94
