Qhov siab tshaj plaws ua haujlwm kub ntawm TP446 raj yog dab tsi?
TP446 stainless hlau tubing tshwj xeeb yog tsim los rau siab - daim ntawv thov kub thiab feem ntau haum rau ib puag ncig mus txog 1,150℃(2,100℃F). Ua tsaug rau nws cov ntsiab lus chromium siab -xws li ntawm 26% mus rau 30%- cov khoom no nthuav tawm tshwj xeeb rau kev ntsuas. Txawm hais tias nws tuav cov oxidation zoo heev ntawm qhov kub txog li 1,000℃(1,832℃F), nws qhov siab - qhov kub thiab txias yog qhov qis.
yuav TP446 tshav kub exchanger raj
1. Peb stainless hlau tubing undergoes kaj annealing, sab hauv weld hlaws tshem tawm, thiab precision polishing. Qhov saum npoo roughness ntawm cov tubing tuaj yeem tswj tau li ntawm 0.3μm.
2. Tag nrho cov ntaub ntawv raw yog los ntawm cov renowned steel mills, xws li TISCO, Baosteel, thiab Zhangpu.
3. Peb cov tubing tau txais ntawv pov thawj xws li AD 2000-W0, PED 2014/68/EU, thiab ISO 9001: 2015.
4. Thoob plaws hauv tag nrho cov txheej txheem tsim khoom, peb xyuas kom meej cov ntaub ntawv traceability.
Peb tau nruab nrog tsis yog -kev kuaj kev puas tsuaj (NDT) muaj peev xwm, xws li kev sim online eddy tam sim no, nrog rau kev kuaj hydrostatic lossis pneumatic leak test.
Flaring & Flattening Tests:Los xyuas kom meej ductility rau raj - mus rau -tubesheet expansion.
Kev kuaj Hardness:Guaranteed max 95 HRB (207 HBW) ib tus qauv.
Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT):100% Eddy Tam sim no lossis Hydrostatic kuaj.
Intergranular Corrosion (IGC) Test:Muaj raws li qhov kev thov kom paub tseeb cov khoom siv purity.
Plastic Sleeving: Txhua lub raj TP446 yog ib leeg nyob rau hauv lub tes tsho tiv thaiv yas los yog PE zaj duab xis.
End Caps: Ob qhov kawg ntawm cov hlab yog haum nrog siab -cov yas zoo lossis LDPE kawg lub kaus mom.
Hexagonal Bundling: Cov raj feem ntau yog teem rau hauv hexagonal bundles los xyuas kom meej qhov zoo tshaj plaws kev ruaj ntseg.
Siv cov Plywood Crates (pom zoo): Rau kev thauj mus los thoob ntiaj teb, peb siv plywood crates uas ua raws li ISPM-15 tus qauv (fumigation-free). Cov crates no muab kev tiv thaiv sab nraud, muaj txiaj ntsig zoo tiv thaiv cov ntsiab lus tiv thaiv stacking siab thiab lateral cuam tshuam.
