ASME SB338 UNS R50400 Seamless Titanium Tubes

Txheej txheem cej luam ntawm ASME SB338 UNS R50400

ASME SB-338 yog tus qauv specification rau seamless thiab welded titanium thiab titanium alloy tubing rau siv nyob rau hauv tshav kub exchangers, nto condensers thiab evaporators. Nws txhais cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov ntev thiab cov kev xav tau kuaj, suav nrog kev sib tw, flaring thiab tsis muaj kev puas tsuaj. UNS R50400 yog cov khoom lag luam ntshiab (CP) Qib 2 titanium tubing uas sib txuas nrog lub cev tsis muaj zog nrog lub zog siab thiab zoo heev corrosion kuj muaj nyob rau hauv titanium. Vim tias nws tsis muaj qhov ntev seam, seamless tubing muaj zog dua thiab siab tsis kam tshaj welded tubing, thiab nws yog dav siv hauv roj thiab roj, tshuaj ua haujlwm, aerospace thiab lub zog tsim.

Corrosion Resistance thiab Daim Ntawv Thov

Titanium Qib 2 ua tau zoo heev nyob rau hauv ib puag ncig chloride, nrog rau cov dej hiav txwv thiab tshuaj dawb, nrog kev tiv thaiv corrosion nyob deb tshaj ntawm cov hlau tsis muaj steel thiab zoo tshem tawm pitting thiab crevice corrosion. Nrog lub zog tensile ntawm 345-400 MPa thiab qhov ceev ntawm tsuas yog 4.5 g / cm³, nws ua rau lub teeb yuag hluav taws xob tsim hluav taws xob thiab txo cov nqi txhawb nqa. Nws kuj yog biocompatible heev thiab tsis yog - tshuaj lom, uas txhawb kev siv tshuaj thiab kev siv tshuaj. Cov ntawv thov muaj xws li condensers, heat exchangers thiab evaporators hauv fais fab nroj tsuag thiab desalination chaw, marine piping systems, chemical processing equipment and aerospace components. Cov raj feem ntau muab nrog rau daim ntawv pov thawj zeb xeem ib EN 10204 3.1 thiab cov ntaub ntawv pov thawj ntawm cov neeg sab nrauv corrosion thiab metallurgical tsom xam.

Cov lus nug nquag

Q1. UNS R50400 yog dab tsi?
UNS lub npe ntawm kev lag luam ntshiab Qib 2 titanium, siv rau seamless thiab welded tubing nyob rau hauv tshav kub exchangers thiab condensers.

Q2. Qhov txawv ntawm Qib 2 thiab Qib 2H yog dab tsi?
Qib 2H yuav tsum muaj lub zog tensile tsawg dua ntawm 400 MPa piv rau 345 MPa rau Qib 2; cov yield zog ntau thiab elongation yog tib yam.

Q3. Vim li cas titanium siv rau condensers?
Nws tiv taus cov tshuaj chloride pitting thiab crevice corrosion nyob rau hauv seawater thiab brine ua rau nws ntev -cov ntaub ntawv lub neej rau marine txias kev pab cuam.

Q4. Dab tsi yog GB thiab JIS sib npaug?
GB/T 3625 TA2 thiab JIS H 4600 Chav Kawm 2; Qhov sib npaug DIN yog 3.7035 rau DIN 17860 thiab qhov sib npaug ISO yog Qib 2 rau ISO 5832-2.

Q5. Puas yog seamless lossis welded titanium tubing muaj zog dua?
Seamless tubing tsis muaj longitudinal weld thiab muaj zog dua thiab siab tsis kam tshaj welded tubing.

Q6. Qhov kev xeem twg siv?
Raws li ASME SB-338, tubing yog kuaj los ntawm flattening, flaring thiab non-destructive txoj kev, nrog mechanical testing ntawm cov khoom xa tuaj.
