Piping kev txhawb zog. Zawv zawg them nyiaj yug rau pipelines

Thaum pw txhais tau tias mus haus dej kom ntau tshaj lub caij tseem ceeb ntawm lawv installation no yog ncua kev kawm ntawv thiab piping txhawb, uas yog steel lug. Lawv lub hom phiaj - cov xaav ntawm qhov ceeb thawj loads uas yog generated los ntawm lub raj dej system. Lub caij nplooj ntoos hlav units, ncua kev kawm ntawv, kev pab txhawb ib feem ntawm piping tshuab rau ntau yam kev siv, xws li: hlauv taws xob Housing thiab communal cov kev pab cuam, roj thiab roj pipelines, cov txheej txheem pipelines ntawm thermal fais fab nroj tsuag, muaj nroj tsuag thiab nuclear fais fab nroj tsuag.

Raug tshem tawm thiab cov yeeb nkab txhawb - ib tug hlau qauv ntawm ntau hom thiab txoj kev fastening cov kav dej los ntawm txoj kev uas fixation yog nqa los yog kom du zog ntawm tus txhawb platform.

Classification raws li tus qauv ntawm daim ntawv thov

1. Rooj noj kev txhawb yog tsau nyob rau hauv lub raj dej, thiab lawv tsis tas rau cov nyiaj them yug qhov chaw, kom ntseeg tau lub dawb zog ntawm cov yeeb nkab raws nws axis.
2. Swb bearings yog xam tau tias yog ib daim ntawv ntawm rooj noj bearings. Lawv cia zog ntawm pipelines nyob rau hauv lub transverse thiab longitudinal kev taw qhia.
3. Taag yeeb nkab txhawb - rigidly tsau mus rau lub raj thiab yog li lawv tus kheej yog welded rau cov nyiaj them yug platform.
4. Raug tshem tawm - ib tug qauv uas mus rau Mount piping mus rau lub joists, daim hlau sib tshooj, qab nthab lug etc. Lawv raug xa mus rau raws li lub rooj noj lub caij.

nta

Feem ntau, cov yeeb nkab txhawb ua los ntawm cov hlau. Lawv installation yuav tsum tau ua xwb los ntawm cov tub txawg, vim kev installation yuav ua rau raug mob: rau cov ntsiab dab tsi rau ib tug loj load yog tsis tsuas yog nyob rau cov kav dej lawv tus kheej, tab sis kuj los ntawm cov kua circulating los ntawm lawv.

Mounting yuav ua tau los ntawm txawv technologies: los ntawm Vuam khoom, nrog clamps. Hlau hom rau kev txhawb xaiv nyob ntawm seb nws tus yam ntxwv. Qhov loj tshaj plaws uas nws muaj peev xwm mus mas siab loads. Span pipelines nyob rau hauv lub hom, cov kev tshaj tawm thiab siab ntawm cov thauj yeeb tshuaj, yeeb nkab diameters thiab cov installation tsim technology.

taag kabmob

Cov lug yog siv rau lub koom haum ntawm lub saum toj no-av thiab underground systems. Cov kev txhawb zog yog muab tso rau tshwj xeeb compensators, uas yog tsim los txo cov kev tsis zoo lwm yam: ntau yam ntawm deeg, hloov mus hloov los ntawm sab hauv keeb kwm, tsis ruaj tsis khov kub.

Nyob rau hauv tas li ntawd, cov yeeb nkab txhawb ua raws li ib tug thermal insulator. Feem ntau cov feem ntau, cov designs yog pom nyob rau hauv sab qaum teb cheeb tsam ntawm Russia, qhov twg muaj teeb meem loj raws caij nyoog thiab txhua txhua hnub kub hloov mus hloov los. Yuav ua li cas yog tsau txhawb, koj yuav saib tau los ntawm cov kev yees duab hauv qab no.

Zawv zawg them nyiaj yug rau pipelines

Cov designs txawv los ntawm tsau txhawb uas muaj peev xwm tau txais cov ntsug load. Txawm li cas los, lawv tsis muaj feem xyuam rau lub deterioration ntawm pipelines. Thaum lub sij hawm lub xaav ntawm pipelines yam ntxwv kub hloov, tsis txhob ua rau kom lawv stability rooj noj kev txhawb zog.

hom

Rooj noj kev txhawb yog muab faib mus rau hauv lub pob, caij nplooj ntoos hlav, yoke, zawv zawg thiab ntau lwm tus neeg. Lub ob hom yog siv rau cov tshuab uas deforms nyob rau hauv tus ntawm kub hloov mus hloov los.

Lub caij nplooj ntoos hlav ntsiab yog tsim nyog rau kev pab tiv thaiv tiv thaiv co systems. Thaum ntawm tej kaum tsev pipelines siv pob tsim, txij li thaum lawv tso cai rau lawv dawb zog. Rau fastening kab rov tav lug siv ncua kev kawm ntawv cov khoom.

kev faib

Nyob rau hauv tas li ntawd, cov ntaub ntawv hais txog cov kav dej yog txwv kom muab zais nyob rau hauv lub tshuab thiab tsim nta ntawm lub installation:

• Lub cev clamp khoom. Nws yuav ua tau ob qho tib si mobile thiab nyob ruaj ruaj yeeb nkab kev txhawb zog. Faib mus rau hauv cov ntsiab nrog ib tug dab tshos tiaj tus thiab puag ncig hom. Tus thawj yog tsuas yog siv rau steel lug. Txhawb nrog puag ncig yam quab yuav siv tau ob qho tib si rau steel thiab rau pre-insulated kav. Tsis tas li ntawd rau no hom ntawm cov khoom muaj cov nyiaj them yug platter, uas txawv los ntawm muaj ribs.
• Case Weld them nyiaj yug. Nws yog heev yooj yim rau nruab, dhau li ntawm tus txawv uas tsis muaj nqi. Nws yog siv rau steel lug. Nws yuav ua tau ob leeg tsau thiab zawv zawg them nyiaj yug rau hauv lub raj dej.
• Panelboard. Tej khoom uas yog yuav tsum tau rau luag tus ntsug khej. Lawv tau koom ua ke los ntawm Vuam. Feem ntau cov feem ntau ntsia qhov twg yuav tsum tau mus kis tau los ntawm cov phab ntsa. Lawv raug xa mus rau ib tug taag them nyiaj yug.
• Hais khauj tsiav khoov rau ob sab. Xws li ib tug kev pab txhawb nqa yog muab tso rau hauv lub raj dej khoov. Nws yuav ua tau mobile, thiab nyob ruaj ruaj. Kuj siv raws li ib tug kho vajtse Symptoms.
• Qhib-ncej. Nyob rau hauv kev, nws yog tus txheem clamps. Qhov no tsau thiab mobile piping txhawb. Tsis ntev los no designs muab free zog, thaum lub sij hawm thawj kev cob cog rua rau lub hauv paus los ntawm Vuam. Tej khoom uas yog feem ntau xa mus rau raws li guides Chomutov.

Installation ntawm zawv zawg bearings

Qhov kev ncua deb ntawm cov lug yog xam zuj zus rau txhua cov yeeb nkab, nws nyob ntawm txoj kab uas hla thiab lub hom piping. Piv txwv li, piping ntawm cua kub tes hauj lwm los yog dej kub mov kav uas yog siv nyob rau hauv polyurethane ua npuas ncauj rwb thaiv tsev, nws yog tsim nyog tsawg heev kev ncua deb ntawm lub rooj noj txhawb es tsis cov dej txias mov. Tus tsim cov txheej txheem yog txiav txim los ntawm lub hom thiab txhawb tsim, installation qhov chaw ntawm txhua yam khoom, uas yog nqa tawm lub dag lub zog muab xam.

Rooj noj cov khoom mounted ncaj qha rau ntawm cov kav dej, ua ntej dragging nyob rau hauv housings, yog li tsis txhob puas tsuaj rau lawv Hoobkas-insulating txheej. Ntawm cov uas tuav thiab hlau qauv yog ua stacking txhawb nyob rau hauv ib tug txheej unbonded web khoom muab tshuaj ntxuav rau ntawm qhov chaw yog thov roj nplua nyeem, piv txwv li graphite.

Thaum kawm tiav ntawm lub installation ntawm mobile yees yog nqa tawm vuam clamps thiab khi rau crimping hlab. Ces qhov chaw ntawm kev raug mob Hoobkas rwb thaiv tsev txheej thiab vuam khoom xim los tiv thaiv los ntawm cov sab nraud ib puag ncig.
