Dab tsi yog qhov txawv ntawm Qws, Tube, thiab Yeeb Nkab hauv Stainless Hlau?

1. Cov npe khoom thiab cov ntsiab lus (lus Askiv-Suav piv)

Lub npe Askiv Suav lub npe Lus Txhais & Yam ntxwv
Hloov Tuam Tshoj Stainless Hlau Round Feem ntau yog hais txog kub-dov, forged, lossis txias-draw cov khoom puag ncig. Feem ntau ≥10mm inch, siv rau kev ua haujlwm ntxiv.
Qws Tuam Tshoj Stainless Hlau Rod Tej zaum yuav xa mus rau round rods, hex rods, los yog square rods. Feem ntau me me-inch khoom tuav (xws li, 2mm-50mm) nrog precision siab dua, haum rau fasteners, precision machining qhov chaw, thiab lwm yam.
Daim ntawv Stainless hlau Sheet Feem ntau ≤6mm hauv thickness, feem ntau yog txias-dov, nrog du nto. Siv hauv architecture, khoom siv, khoom siv hauv chav ua noj, thiab lwm yam.
Phaj 不锈钢中厚板 (Stainless hlau phaj) Feem ntau ≥6mm hauv thickness, feem ntau yog kub dov. Haum rau cov hlab ntsha siab, cov khoom siv, cov khoom siv hnyav.
Tube 不锈钢管 (装饰管) (Stainless Steel Tube - Kho kom zoo nkauj / qauv) Feem ntau yog hais txog cov txheej txheem, txhua yam, lossis zoo nkauj tubing. Yuav welded los yog seamless. Tsom ntsoov rau qhov ntev precision thiab zoo li, piv txwv li, rau rooj tog lossis railings.
Yeeb 不锈钢管 (工业管) (Stainless Steel Pipe - Muaj) Feem ntau yog siv rau kev lag luam piping, xws li kev thauj mus los, cov khoom siv hluav taws xob, cov boilers. Hais txog phab ntsa thickness, siab ntsuas, thiab cov qauv specifications (piv txwv li, SCH10, SCH40).
 

2. Cov ntsiab lus tseem ceeb sib txawv

Qeb Khoom Hollow Daim ntawv thov tseem ceeb tsom Manufacturing yam ntxwv
Round / Qws ✅ Yog ❌ Tsis muaj Machining, pwm, fasteners Kub dov, forging, txias kos duab, sib tsoo
Ntawv / phaj ❌ Tsis muaj ❌ Tsis muaj Cov qauv, kho kom zoo nkauj, cov hlab ntsha siab Cold-rolled (daim ntawv) / kub dov (phaj)
Tube ❌ Tsis muaj ✅ Yog Kho kom zoo nkauj, structural, rooj tog Welded / txias-draw / seamless
Yeeb ❌ Tsis muaj ✅ Yog Kev thauj cov kua dej, cov kab hluav taws xob siab Seamless / welded, tus qauv ntsuas
 

3. Cov lus qhia ceev ceev:

  • Hloov= General-purpose round bar, rau kev ua haujlwm ntxhib

  • Qws= Me me, ntau meej bar

  • Daim ntawv= Nyias cov khoom (≤6mm)

  • Phaj= Cov khoom tuab tuab (≥6mm)

  • Tube= Rau kev zoo nkauj / qauv siv

  • Yeeb= Rau kev thauj cov kua (ntsuas los ntawm lub siab / tus qauv)

 

I. ASTM (American Society for Testing and Materials)

Qws / Round Bar

  • Daim ntawv pov thawjASTM A276 (Standard Specification for Stainless Steel Bars and Shapes - Kub Rolled thiab Cold-Drawn)

  • Txhais: Khoom tuav nrog ntau yam hla ntu (puag ncig, square, hexagonal, thiab lwm yam) siv rau kev siv cov txheej txheem thiab machining.

  • Nco tseg: Hauv ASTM terminology, "round bar" thiab "rod" feem ntau siv sib hloov. Txawm li cas los xij, "qhib" feem ntau yog hais txog txoj kab uas hla me me, cov kab txias txias nrog qhov siab dua qhov tseeb.

Daim ntawv / Phaj

  • Daim ntawv pov thawjASTM A240 (Standard Specification rau Chromium thiab Chromium-Nickel Stainless Hlau Phaj, Sheet, thiab Sawb rau Cov Nkoj Siab thiab rau Kev Siv Dav Hlau)

  • Txhais qhov txawv:

    • Daim ntawvThickness: 6.35 hli (1/4 nti)

    • PhajThickness ≥ 6.35 hli

  • Ob leeg yog cov khoom tiaj tus, tab sis txawv ntawm thickness thiab daim ntawv thov tsom.

Yeeb

  • Daim ntawv pov thawjASTM A312 (Standard Specification rau Seamless, Welded, thiab hnyav hnyav ua haujlwm Austenitic Stainless hlau kav)

  • Daim ntawv thov: Siv rau kev thauj cov kua dej. Ua kom pom tseeb hauv txoj kab uas hla, nominal yeeb nkab loj (NPS), thiab chav kawm siab (piv txwv li, SCH 40).

Tube

  • Cov qauv siv:

    • ASTM A269 (Standard Specification for Seamless and Welded Austenitic Stainless Steel Tubing for General Service)

    • ASTM A554 (Standard Specification rau Welded Stainless Hlau Mechanical Tubing)

  • Ua kom pom tseeb: Sab nraud txoj kab uas hla thiab nto zoo. Feem ntau yog siv rau kev tsim, tshuab, lossis kho kom zoo nkauj.

II.ASME (American Society of Mechanical Engineers)

  • Cov qauvASME B36.10M / B36.19M

  • Txhais: Txhais qhov ntau thiab tsawg ntawm phab ntsa thickness (piv txwv li, SCH 10, SCH 40) rau stainless hlaucev.

  • Siv: Feem ntau siv nrog ASTM A312 hauv kev tsim cov kav dej.

III.ISO (International Organization for Standardization)

  • TS EN ISO 15510: Stainless hlau qib sib piv (tsis txhais cov ntaub ntawv khoom).

  • TS EN ISO 9445: Tolerances thiab qhov ntev rau txias-dov strip, ntawv, thiab phaj.

  • TS EN ISO 1127: Txheem qhov ntev rau cov raj hlau - qhov txawvcevthiabcevlos ntawm sab nraud txoj kab uas hla vs. nominal txoj kab uas hla.

IV.EN (European Norms)

  • TS EN 10088-2: Stainless hlau ca khoom (ob daim ntawv thiab phaj) rau cov hom phiaj dav dav.

  • TS EN 10088-3: Stainless hlau ntev cov khoom xws li tuav thiab xaim.
