Parallel Finned Tubes|Rectangular Finned Tubes

Khoom Description

Parallel Finned Tubes yog dab tsi?

Parallel Finned tubes yog ua los ntawm welded square fins. Nws kuj hu ua H hom finned tubes. Parallel finned tubes tuaj yeem ua ob lub raj lossis ib leeg. Parallel finned tubes tsim los ntawm kev tiv thaiv vuam cov fins ntawm cov hlab.

Parallel finned tubes siv:

Parallel finned tubes muaj kev sib koom ua ke ntau rau cov ntawv siv nrog cov khib nyiab rov qab boilers thiab cov neeg lag luam khiav lag luam nrog cov thee, cov roj hnyav, cov khoom pov tseg lossis cov khoom siv hauv tsev tsis kam hlawv.

Parallel finned tubes tso cai rau kev siv hauv txhua qhov kev tu lub cev: tua blasting, cua lossis chav tshuab, ntxuav ...

Qhov 'Double H' tsim los txuas ob lub raj nrog cov hlau fins tib lub sijhawm. Qhov kev teeb tsa no tuaj yeem txo tus naj npawb ntawm cov kev txhawb nqa uas xav tau vim nws qhov kev nruj nruj.

Parallel finned tubeskom zoo dua,

Kev sib dhos ntawm cov fins nyob rau hauv cov pob khoom tso cai rau kev tsim ntawm tus kheej tu cov kab sib txuas, nrog rau kev poob qis.

Parallel finned tubes tsom

Fin pitch los ntawm 10 mus rau 30 mm.

Tube ntev mus txog 15 meters.

Fin cuam tshuam tuaj yeem thov.

Parallel finned tubes khoom:

Lub hauv paus khoom siv rau lub raj thiab fins: carbon steel A179, A192, Alloy Steel as per A213 A335, Stainless hlau A312, Tau tshaj cam khwb cia hlau finned hlab rau hybrid units. Tshwj xeeb fin qhov ntev ntawm kev thov.

Raws li cov kev xav tau ntawm kev lag luam hauv tsev, tom qab xyoo dhau los ntawm kev paub thiab kev kawm los ntawm cov teb chaws siab heev, peb lub tuam txhab tau hloov kho H-hom finned tube / Parallel finned tubes vuam khoom, uas muaj qib siab ntawm automation. Lub vuam tshuab thiab cov khoom lag luam zoo tau mus txog cov ntawv pov thawj ntawm International Classification Society thiab lwm lub koom haum muaj ntawv pov thawj.

1. H-hom finned tube / Parallel finned hlab Vuam lub zog thiab ruaj khov

1.1 Pull off force test: ntau dua 200MPa los yog ib nrab kua muag ntawm cov yeeb nkab steel

1.2 Weld width: greater than fin thickness, i.e. welding rate>99%

1.3 Kev ruaj ntseg ntawm vuam lub zog: thawj daim ntawm txhua qhov kev hloov yuav tsum tau welded kom tau raws li qhov yuav tsum tau muaj ntawm 2.1 lossis 2.2

1.4 Weld dabtsi yog khoov kev ntsuas: cov fins yog khoov 20 degrees sab laug thiab sab xis, khoov sab laug thiab sab xis ob zaug, thiab cov vuam tsis muaj kab nrib pleb

1.5 Kev sim rauj: ntaus rau sab sauv ntawm cov fin sib npaug rau cov yeeb nkab steel kom txog thaum lub fins poob, thiab cov fin nws tus kheej yuav tsum tsis txhob tawg.

1.6 Yog tias qhov kev xeem tsis ua tiav, lub annealing muaj nuj nqi yuav tsum tau qhib

2. H-hom finned tube / Parallel finned tubes tshav kub cuam tshuam cheeb tsam

Kev ntsuas nrog lub tshuab ntsuas ntsuas thiab microhardness tester

Qhov tob ntawm tshav kub cuam tshuam cheeb tsam ntawm cov yeeb nkab steel yog tsawg dua 0.5mm

3. H-hom finned tube / Parallel finned tubes qhov tseeb

3.1 Zuag qhia tag nrho ntev ntawm tis ntu - 1mm ~ +1mm segmental motion precision - 0.5mm ~ +0.5mm

3.2 Qhov nrug - 0.2mm ~ +0.2mm

3.3 Verticality ntawm fins thiab steel kav - 1 degree ~ +1 degree

3.4 Qhov flatness ntawm pob tw welded fins nyob rau hauv tib pab pawg yog - 0.2mm ~ +0.2mm, tshwj tsis yog rau qhov siab sib txawv los ntawm lub thickness kam rau ua ntawm fins

3.5 Qhov siab sib txawv ntawm pob tw welded fins nyob rau hauv tib pab pawg - 0.2mm ~ +0.2mm

3.6 Tolerance ntawm ob lub yeeb nkab chaw nrug - 0.5mm ~ +0.5mm

3.7 Nyob rau hauv cov xwm txheej ntawm tib cov yeeb nkab steel, tib daim ntawv sib nrug thiab daim ntawv xov tooj, qhov ntev ntawm qhov sib txawv finned tubes tom qab vuam zoo ib yam.

4. H-hom finned tube / Parallel finned tubes vuam ceev

Lub hauv paus raj sab nraud txoj kab uas hla 25 ~ 51, fin thickness 2 hli, txhua khub ntawm vuam lub sij hawm tsawg dua 3s (tsis suav pub mis thiab unloading lub sij hawm thiab annealing lub sij hawm)
