Yuav Ua Li Cas Xaiv Qhov Loj Aluminium Luj Tshib rau HVAC Systems

Xaiv qhov loj ntawm lub luj tshib ntawm lub luj tshib rau HVAC system yog ib kauj ruam ua tau zoo uas cuam tshuam rau qhov hnyav ntawm kev teeb tsa, kev poob siab, thiab kev pabcuam lub neej. Cov lus qhia no suav nrog yuav ua li cas aluminium yeeb nkab luj tshib loj npaum li cas rau HVAC hydronic thiab refrigerant piping, cov qauv siv, thiab ib kauj ruam los ntawm kauj ruam txoj kev koj tuaj yeem siv los qhia lub luj tshib. Nws siv rau cov dej txias, dej condenser, thiab refrigerant_lines, tsis yog rau cov ntawv hlau duct.

Lub luj tshib aluminium rau HVAC yog lub taub qab vuam yeeb nkab haum uas hloov cov kev taw qhia ntawm kev ntws hauv dej los yog cov tub yees. Ob qhov kawg yog beveled rau tag nrho kev nkag mus rau weld, yog li qhov sib koom ua ke sib tw cov yeeb nkab lub zog thiab tawm hauv lub bore du. Aluminium yog xaiv nyob rau hauv HVAC qhov hnyav qhov teeb meem (ru tsev chav nyob, offshore, marine, mobile khoom) los yog qhov twg corrosion kuj thiab tsis sparking cwj pwm yog pab tau.

Kauj Ruam 1: Sib phim lub Nominal Pipe Size rau cov yeeb nkab

Lub luj tshib loj yuav tsum phim cov yeeb nkab uas nws koom. Rau NPS cov yeeb nkab loj, sab nraud txoj kab uas hla raws li ASME B36.10M, thiab lub luj tshib yog dimensioned rau tib NPS. Feem ntau HVAC yeeb nkab ntau thiab tsawg khiav los ntawm NPS 1/2 (DN15) mus txog NPS 12 (DN300) thiab loj dua rau cov cog mains. Ib txwm paub meej tias qhov tseeb sab nraud thiab phab ntsa tuab ntawm cov yeeb nkab koj txuas, vim tias cov haujlwm txhuas yuav siv cov qauv NPS qhov ntev, metric qhov ntev, lossis qhov project teev qhov ntau thiab tsawg.

Kauj Ruam 2: Xaiv Phab Ntsa Thickness (Tshooj)

Phab ntsa thickness yog muab raws li lub sij hawm los yog raws li ib tug teev cov zauv phab ntsa. Rau txhuas HVAC kab, cov sij hawm ntau yog 5S, 10S, thiab 40S. Cov sij hawm sib zog (5S, 10S) yog qhov zoo rau cov dej txias txias, thaum 40S yog siv qhov chaw siab dua lossis muaj zog tuav ntau dua. Cov phab ntsa thickness teev cov phab ntsa yam tsawg kawg nkaus tom qab tsim thiab ua rau lub siab tso cai, yog li nws yuav tsum tau xaiv nrog lub kaw lus tsim siab, qhov kub thiab txias, thiab cov cai, tsis tau twv.

Kauj ruam 3: Xaiv qhov Khoov Radius (LR lossis SR)

Lub vojvoog tswj kom nruj npaum li cas lub luj tshib tig:

Ntev vojvoog (LR): centerline radius=1.5 x NPS (1.5D). Kev txo qis qis, nyiam rau feem ntau HVAC khiav.

Short radius (SR): centerline radius=1.0 x NPS (1.0D). Ntau compact, siv qhov chaw nruj.

Rau HVAC, lub vojvoog ntev yog qhov kev xaiv ib txwm vim tias cov tshuab feem ntau ntev thiab tsis tshua muaj teeb meem. Siv lub vojvoog luv luv tsuas yog thaum lub hnab ntawv routing yuav tsis lees txais lub vojvoog ntev cheb, xws li nyob rau hauv cov khoom siv ntim khoom los yog cov skid units.

Kauj ruam 4: Xaiv lub kaum sab xis

90 degree: lub kaum sab xis tig, feem ntau.

45 degree: kev hloov maj mam, txo qis, siv los hloov lossis yooj yim hloov pauv. Muab nyob rau hauv ntev radius.

180 degree: rov khoov, siv nyob rau hauv coils thiab tshav kub exchanger manifolds.

Rau ib qho kev teeb tsa, ob lub luj tshib 45℃nrog qhov sib txuas ncaj tuaj yeem hloov tau ib qho 90℃tig thaum xav tau, tab sis qhov ntawd ntxiv fittings thiab welds.

Kauj Ruam 5: Xaiv cov Aluminium Alloy

Rau feem ntau lub tsev HVAC dej loops, 6061 T6 los yog 6063 yog txaus. Rau offshore platforms, nkoj, los yog ntug dej hiav txwv cog, 5083 muab zoo seawater corrosion kuj.

Kauj Ruam 6: Paub meej cov qauv

Aluminium HVAC lub luj tshib tau teev tseg rau:

ASTM B361 (ASME SB 361) rau cov khoom thiab haum specification

ASME B16.9 rau lub vojvoog ntev ntev

ASME B16.28 rau luv vojvoog qhov ntev

ASME B16.25 rau kev npaj vuam kawg

Ib qho kev nug tiav yuav tsum hais txog cov alloy thiab temper, lub kaum sab xis, ntev los yog luv luv vojvoog, nominal loj los yog tiag tiag sab nraud txoj kab uas hla, phab ntsa thickness los yog lub sij hawm, thiab dimensional standard.

Kauj Ruam 7: Tshawb xyuas Flow Velocity thiab Siab Poob

HVAC cov tshuab dej feem ntau tsis tshua muaj siab, thiab cov qauv tsim tawm feem ntau yog khaws cia rau hauv qhov nruab nrab kom txwv cov suab nrov thiab lub zog twj. Lub luj tshib ntev ntev ntxiv qhov sib npaug ntev dua li lub luj tshib luv luv, yog li kev qhia LR hauv kev ua haujlwm ntev pab tswj tag nrho lub zog siab poob. Lub siab tso cai ntawm lub luj tshib yog teem los ntawm alloy, temper, phab ntsa thickness, kub, thiab raws li txoj cai kav, tsis yog los ntawm lub vojvoog. Tsis txhob nyeem qhov ntsuas kub ntawm lub rooj steel thiab siv rau txhuas; aluminium tsis them los ntawm cov rooj ntsuas steel hauv ASME B16.9, thiab tus nqi yuav tsum raug tsim los ntawm kev tsim.

Center to End Dimensions (90 Degree)

Qhov nruab nrab mus rau qhov kawg qhov ntev tsuas yog nyob ntawm qhov nominal loj thiab lub vojvoog hom, tsis yog ntawm phab ntsa thickness. Cov nqi hauv qab no yog cov npe siv los ntawm ASME B16.9 thiab ASME B16.28.
