Alloy Seamless Yeeb Nkab

 

 

Alloy Seamless steel yeeb nkab yog ib hom siab - Kev Ua Yeeb Yam (Moladium (Niobium (NB), thiab ua tiav los ntawm Seamless Technology. Piv nrog tib neeg cov pa roj carbon hlau seamless kav, alloy seamless kav, kub} kub sab, thiab tau thov hauv kev lag luam kev lag luam.

 

Lub zog siab:

Qhov sib ntxiv ntawm cov ntsiab lus endoying (xws li MN, KN, TENTILE PROUTT lub zog thiab tensile lub zog muaj zog dua qub thiab lwm yam kev siv hluav taws xob.

Nws yog siv rau high - cov roj siab (xws li cov roj boiles, xws li cov roj ruaj khov (xws li cov pob tw), thiab lwm yam.

Zoo heev - kub kuj:

Cov ntsiab lus tshwj xeeb aloying (CR, MO, NB, ti, ti) loj txhim kho lub siab - kub lub zog thiab creep tsis kam ntawm cov hlau.

Nws yog tsuas yog siv nyob rau hauv high - kub thiab siab {{

Zoo corrosion resistance:

Qee cov ntsiab lus sib dhos (xws li CR, NI, MO, CU) tuaj yeem ua rau oxidation oxide cov yeeb yaj kiab, sulfidation, acids, alkalis, thiab lwm yam.

Daim ntawv thov cov nroj tsuag (reactor kav dej, cov roj cua sov (ov)

 

Zoo heev qis - kub nruj:

Cov qauv tsim tshwj xeeb (xws li ntxiv rau ntawm NI) tuaj yeem txhim kho cov tawv nqaij tawv ntawm cov hlau ntawm cov kub tsis tshua kub thiab tiv thaiv kev tawg.

Nws yog siv rau tsawg - sov qhov chaw ib puag ncig xws li lw (liquefied tso tsheb hlau luam / kua roj oxygen

 

Zoo heev solderability thiab ua kev ua tau zoo:

Los ntawm kev ua kom zoo thiab kho kom sov, alloy seamless hlab tsis tsuas yog kev ua tau zoo tab sis kuj muaj kev ua haujlwm zoo nyob ntawm cov ntsiab lus alloy).

 

 

Cov tub ntxhais ntawm seamless steel kav dag dag nyob rau hauv "seamless", uas yog, tag nrho cov yeeb nkab tsis muaj weld seams. Ob qho txheej txheem sib dhos hauv qab no yog cov txheej txheem saws:

Thaum xaiv Alloy Seamless steel kav, thov nkag siab txog cov ntsiab lus tseem ceeb hauv qab no:
COV KEV PAB CUAM: Ua haujlwm kub? Nyob rau hauv siab? Ntws xov xwm thiab lawv corrosiveness? Puas yog qis dua kub / cuam tshuam? Nws puas yog ib qho kev ua haujlwm hnyav? Nws puas yog lub voj voog kub?

 

Qhov twg ntawm cov kev ua tau zoo hauv qab no yuav tsum tau ua tiav: lub zog, kub tsis kam, corrosion tsis kam thiab tawv?

 

Cov Txheej Txheem Muaj Cov Qauv: Ua raws li cov qauv kev lag luam tshwj xeeb (xws li ASME B31.1 / 3, GB150) thiab cov qauv khoom (xws li ASTM, en, GB).

 

Kev khwv nyiaj txiag thiab muaj: nyob rau hauv lub rooj sib tham txog kev ua tau zoo, xaiv cov khoom tshwj xeeb nrog kev ua haujlwm siab thiab yooj yim.

 

Kev tsim khoom thiab kev sib txuas: yog yooj yim rau cov txheej txheem / daim ntawv (khoov, flared)? Yog lub vuam txheej txheem ua tiav (xav tau preheating thiab tshaj tawm - kub kub)?

 

Daim ntawv pov thawj zoo: ua cov khoom lag luam zoo ua tiav cov ntaub ntawv zoo (cov ntawv pov thawj cov ntaub ntawv, ntawv xeem, thiab lwm yam)?

 

Kev ua txhaum cai 1: "Alloy Steel" yog tib yam li "stainless hlau".

Kev Hais Kom Zoo: Stainless Hlau yog cov ceg tseem ceeb ntawm cov qib alloy (feem ntau yog hais txog cov qauv steel, qis} {{{{{3} {{{{{{3} {{{3} {{{3} {{{3} {} {{{3} {- {} {{3} {{{3} {- { Ntau cov kav dej alloy tau siv nyob rau hauv high - kub lossis siab {{}}}}}}}}}}}} {, p91).

 

 

MiskPception 2: "Seamless kav" yog twv yuav raug hu zoo dua "Welded kav".

Piav kom meej: Seamless kav yog feem ntau tau zoo dua nyob rau hauv cov nqe lus ntawm siab {{} {{{{2} {{} qhov siab} qhov siab tsis muaj zog. Txawm li cas los xij, hauv cov xwm txheej dog dig nrog nruab nrab thiab qis dua corrosion, xws li erw siab welded kav thiab pom kauv vuam thiab pom cov kauv vuam) muaj cov nqi zoo. Qhov kev xaiv yog nyob ntawm cov kev ua haujlwm tshwj xeeb thiab tus nqi - cov txiaj ntsig kev tsom xam.

 

 

Kev ua txhaum cai 3: Tus nqi ntawm Alloy Hlau Kave yog ib leeg txiav txim siab los ntawm cov khoom siv.

Cov ntsiab lus meej: Cov ntsiab lus xws li (xws li NI, Mo Siab - Zoo Alloy Seamless Tube feem ntau xav tau kev nqis peev tseem ceeb.
