Lub luag haujlwm ntawm cov khoom muaj peev xwm hauv kev faib cov sijhawm
Cov khoom siv yeeb nkab ncaj qha cuam tshuam rau kev ntxhov siab uas muaj kev ntxhov siab (SNyob rau hauv Barlow tus qauv), uas nyob rau hauv cov kab mob caij nyoog xaiv cov sijhawm xaiv. Cov Khoom Sib Txawv (Cov Hlau Hlau, Stainless hlau, Alloy Steel) muaj sib txawv, corrosion zog, thiab siab {{{} Kev ua tau zoo, ua rau sib txawv ntawm cov phiaj xwm qib kev ua haujlwm.
Carbon Steel: feem ntau cov khoom siv rau cov qauv teev cov sij hawm
Carbon Steel (piv txwv li, Q235, API 5) yog siv dav nyob rau hauv cov tsheb kauj vab vim nws lub zog siab thiab tus nqi qis. Nws cov kev ntxhov siab uas muaj kev ntxhov siab los ntawm 100-200 MPA (ua kom haum rau qib 20, kawm rau qib 20-sch 160 qib hauv nruab nrab {10} Qhov nruab nrab scenarios:
Sch 20-sch 40: Siv hauv cov dej hauv nroog, tso dej, thiab kev siv dej ua kua dej tsis muaj zog (siab tsawg dua lossis sib npaug rau 2.0 mpa).
SCH 80-SCH 160: Thov siv rau hauv cov roj thiab roj sib sau cov kab, qis {{}}}} siab cov xov hluav taws xob (siab 2.0-8.0 MPA).
Huayang Steel Yeeb Nkab Cov Hlau Teem Caij Cov Khaub Ncaws Cov Khaub Ncaws Rau 70% ntawm nws cov khoom tawm tag nrho. Piv txwv li, nws API 5L X52 Hluav Taws Xob Hluav Taws Xob Welded Welded Lub Zog Hluav Taws Xob (Sch 40) yog siv sijhawm ntau dua los yog sib npaug ntawm 450 MPA txoj kev xav tau.
Stainless hlau: corrosion - tsis kam raws caij nyoog rau ib puag ncig hnyav
Stainless hlau (piv txwv li, 304, 316L) tau zoo heev corrosion tsis kam tab sis qis dua kev ntxhov siab dua li cov hlau (80-150 mpa). Txhawm rau them nyiaj rau qis dua lub zog, stainless hlau teem cov dej yeeb nkab feem ntau siv cov qhab nia siab dua rau tib lub siab:
Rau cov tsheb thauj khoom siv tshuaj lim dej (corrosive, siab 1.0 MPA), carbon steel siv sch 40, thaum 304 stainless hlau yuav tsum muaj tus qauv hlau tsis muaj tus lej 60 txhawm rau paub meej cov phab ntsa txaus.
Rau seashater desalination systems (siab, siab 1.2 MPA), 316L stainless hlau sch 80.31mm (Nps 8) kom tsis kam ua Saltwater tabs.
Huayang Steel yeeb nkab tsim cov kav hlau stainless hlau cov kauj ruam txee rau cov tshuaj lom neeg, feem ntau 304 / 316L cov qib.

Huayang Steel yeeb nkab tau tsim alloy steel teem cov txheej txheem yeeb nkab rau lub zog kev lag luam, tsom mus rau A335 P22 / P222 / P222 / P222 / P222 / P222 / P91. Nws p22HFW Steel Yeeb Nkab(SCH 120, Nps 10) tau muab rau Shandong 660Mw thermal fais fab nroj tsuag (kev sib luag ntawm 0.1% thiab sib tham cov kev ua haujlwm hauv kev ua haujlwm ntev-ntev.
Lub Sij Hawm Cov Qauv Qeb: Thoob Ntiaj Teb thiab Suav Txawv
Teem sijhawm qib kawm tau los ntawm International thiab Lub Koom Haum Hauv Tebchaws, nrog qhov sib txawv me me, nrog qhov sib txawv me ntsis ntawm cov tshuab. Nkag siab cov kev sib txawv no yog qhov tseem ceeb rau tus ntoo khaub lig- Bycd Prosts thiab import - export lag luam.
Cov Txheej Txheem Thoob Ntiaj Teb: Ansi / ASME B36.10M (North American system)
Tus ANSI / ASME B36.10M Txuj (siv nyob rau hauv North America, Europe, thiab cov roj hauv ntiaj teb thiab cov roj teeb cov sijhawm raws li hauv qab no:
Qib Qib: Sch 5, Sch 10, Sch 20, Sch 30, Sch 40, Sch li 60, SCH 120, SCH 160, SCH 160.
Cov qeb tshwj xeeb: SCH XXS (Ntxiv Ntxiv Ntxiv Zog, Thicker dua SCH 160) thiab SCH STD (tus qauv, sib npaug rau tus sch 40 rau NPS 1-10).
Cov txheej txheem no siv "tus lej lej" kom ncaj qha sawv cev phab ntsa tuab. Piv txwv li, NPS 4 sch 40 yeeb nkab muaj cov phab ntsa tuab ntawm 6.02mm, thaum NPS 4 SCH 80 muaj qhov tuab ntawm 8.56 hli.
Huayang Steel yeeb nkab ua raws li cov arti / ASME B36.10M rau export - kev siv hluav taws xob. Nws API 5L x65HFW Steel Yeeb Nkab(Sch 80, Nps 8) Raug xa tawm mus rau Middle East tau raws li cov qauv ntawm cov qauv (txheej txheem thib peb) thiab hla peb tog thib peb kev soj ntsuam los ntawm SGS.
Suav Txuj Ci: GB / T 28708 (cov ntaub ntawv hauv tsev)
Tuam Tshoj tus GB / T 28708 txheem yog raws li cov qauv thoob ntiaj teb tab sis hloov qee cov sijhawm rau kev lag luam kev lag luam:
Nws khaws cov qib tub ntxhais kawm (SCH 20, SCH 40, SCH 80, SCH 16, SCH 40, SCH 5, SCH 10).
Nws txhais tau tias "nominal siab (PN)" sib xws rau cov sijhawm kawm qib (piv txwv li 40 mpa kom muaj cov hlau, sch 80 matches pn 2.5 mpa).
Qhov kev hloov kho no tau yooj yim rau qib kawm rau cov haujlwm hauv tsev. Piv txwv li, hauv Suav Tebchaws Cov dej num hauv Suav teb, tus pheb 40 yog teev ncaj qha raws li txuam PN 1.6 MPA, zam kev ntxhov siab nyuaj.
Huayang Steel yeeb nkab tsim cov kauj vab cov yeeb nkab hauv kab nrog GB / T 28708 rau kev lag luam hauv tsev. Nws Q235 hluav taws xob tiv thaiv welded veel yeeb nkab (txuj ci
