Phaj 不锈钢中厚板 (Stainless hlau phaj) Feem ntau tuab ≥6 hli, feem ntau yog dov kub. Haum rau cov hlab siab, cov khoom siv hauv tsev, thiab cov ntawv thov kev lag luam hnyav.
Lub raj 不锈钢管 (装饰管) (Stainless Steel Tube - Kho kom zoo nkauj / qauv) Feem ntau yog hais txog cov kav dej uas ua los ntawm cov khoom siv, cov khoom siv kho tshuab, lossis cov kav dej kho kom zoo nkauj. Muaj peev xwm vuam tau lossis tsis muaj qhov sib txuas. Tsom mus rau qhov tseeb ntawm qhov ntev thiab qhov tsos, piv txwv li, rau cov rooj tog lossis cov laj kab.
Yeeb Nkab 不锈钢管 (工业管) (Stainless Steel Pipe - Muaj) Feem ntau siv rau cov kav dej lag luam, xws li kev thauj cov kua dej, cov khoom hloov pauv cua sov, thiab cov boilers. Qhia txog qhov tuab ntawm phab ntsa, qhov ntsuas siab, thiab cov qauv txheem (piv txwv li, SCH10, SCH40).
 

2. Cov Lus Qhia Txog Qhov Txawv Tseem Ceeb

Pawg Khoom khov kho Qhov khoob Lub Ntsiab Lus Tseem Ceeb ntawm Daim Ntawv Thov Cov yam ntxwv ntawm kev tsim khoom
Puag ncig/Qws ✅ Yog ❌ Tsis muaj Kev ua haujlwm, pwm, cov khoom siv txuas Kub dov, forging, txias kos duab, sib tsoo
Daim Ntawv/Phaj ❌ Tsis muaj ❌ Tsis muaj Cov qauv, kho kom zoo nkauj, cov hlab ntsha siab Txias-dov (daim ntawv) / kub-dov (phaj)
Lub raj ❌ Tsis muaj ✅ Yog Kho kom zoo nkauj, cov qauv, rooj tog Welded / txias-kos / seamless
Yeeb Nkab ❌ Tsis muaj ✅ Yog Kev thauj cov kua dej, cov kav dej siab Seamless / welded, kev ntsuas tus qauv
 

3. Cov Lus Qhia Ceev Txog Kev Nco:

  • Puag ncig= Lub voj voog dav dav, rau kev ua cov khoom tsis zoo

  • Qws= Me dua, thiab muaj qhov bar meej dua

  • Daim ntawv= Khoom tiaj tiaj nyias (≤6mm)

  • Phaj= Khoom tiaj tiaj tuab (≥6mm)

  • Lub raj= Siv rau kev zoo nkauj/kev siv qauv

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

 

I. ASTM (Lub Koom Haum Asmeskas rau Kev Ntsuas thiab Cov Khoom Siv)

Qws / Round Bar

  • Tus Qauv SivASTM A276 (Cov Qauv Txheem rau Cov Hlau Stainless Bars thiab Cov Duab - Kub-Dov thiab Txias-Drawn)

  • Kev Txhais LusCov hlau khov kho uas muaj ntau ntu sib txawv (puag ncig, plaub fab, hexagonal, thiab lwm yam) siv rau kev tsim kho dav dav thiab kev siv tshuab.

  • Lus CimHauv ASTM cov lus, "round bar" thiab "rod" feem ntau siv sib pauv tau. Txawm li cas los xij, "rod" feem ntau yog hais txog cov hlau me dua, cov hlau uas rub txias nrog qhov tseeb dua.
