Kev tshem tawm tag nrho cov Fittings

Ib qho ntawm qhov zoo ntawm welded yeeb nkab hla cov ntsia hlau fittings yog tshem tawm tag nrho cov fittings xav tau los koom nrog ib tus neeg ncaj seem ntawm cov yeeb nkab. Nrog screwed yeeb nkab yuav tsum muaj qhov haum ntawm txhua qhov sib koom ua ke hauv txoj kab ncaj nraim ntawm cov yeeb nkab. Vuam, ntawm qhov tod tes, tuaj yeem muab tso ua ke rau hauv txhua daim ntawv ntawm txhua qhov chaw hauv txoj kab ncaj nraim. Tsuas yog ib qho kev npaj ntawm qhov kawg ntawm cov yeeb nkab yog txhua yam uas yuav tsum tau ua.

Ntau zaus thaum cov xov tsis siv, cov yeeb nkab phab ntsa nyias yuav raug xaiv. Rau kev ua haujlwm ntev thiab ua haujlwm loj, qhov no tuaj yeem tsim kev txuag nqi tseem ceeb. Thaum cov kav dej raug ntsia ua ke, muaj ntau qhov tseem ceeb ntawm kev ua haujlwm ntxiv uas yuav tsum tau ua kom tiav cov kav dej thiab muab cov fittings ua ke. Tsis tas li ntawd, muaj cov nqi cuam tshuam nrog txhua qhov threaded fittings. Qee lub sij hawm cov khoom siv rau cov xov yeeb nkab yog qhov nyuaj dua li qee qhov ntawm cov khoom siv vuam yooj yim uas peb tuaj yeem siv rau kev sib txuas cov kav dej ua ke hauv kev siv welded.

Thaum muaj screwed fittings muaj ib qho tseem ceeb ntawm turbulence thiab kua tsis kam mus rau ntws los ntawm cov yeeb nkab. Qhov zoo welded system yog du thiab streamlined ntawm nws sab hauv contour thiab nto.

Kho tau yooj yim

Lub welded yeeb nkab yog kho tau yooj yim dua li ib qho siv cov ntsia hlau fittings. Nrog vuam, feem ntau yuav kho tau nrog cov yeeb nkab nyob rau hauv qhov chaw. Ib tug ntsia hlau yeeb nkab system yuav tsum tau disassembled kho thiab ces reassembled. Muaj ntau qhov tseem ceeb ntawm kev ua haujlwm ntxiv los daws thiab muab tso ua ke uas cov yeeb nkab kaw thiab tsis muaj qhov xau hauv nws. Feem ntau cov yeeb nkab welded tuaj yeem tswj kev vibration zoo dua li cov yeeb nkab ntsia hlau. Lub welded system nyob rau hauv ib qho kev vibrating cheeb tsam yuav tsis yooj yim rau xau thiab ua xoob dua li cov yeeb nkab ntsia hlau.

Thaum nws los txog rau lub sij hawm rau insulate cov kav dej insulating los yog qhwv ib tug welded system yog yooj yim npaum li mus hla tag nrho cov threaded kev twb kev txuas thiab tag nrho cov pob uas tuaj nrog cov neeg fittings.

Nrhiav Closer

Lwm qhov zoo ntawm cov kav dej welded yog thaum cov kav dej yuav tsum nyob ze ua ke. Peb tuaj yeem nrhiav cov kav dej welded ua ke ntau dua li qhov peb tuaj yeem nrog cov kav hlau threaded. Threaded kav yuav tsum muaj chaw kom muaj wrenches thiab lwm yam cuab yeej txuas rau lawv kom lawv tig tau thiab ruaj ntseg.

Kev ua haujlwm rau vuam thiab ntsia hlau cov kav dej me me yog hais txog tib yam. Raws li cov yeeb nkab loj zuj zus, kev ua haujlwm thiab lub sijhawm los txhim kho cov yeeb nkab welded txo, thiab cov yeeb nkab screwed nce. Screwed yeeb nkab kuj xav tau cov cuab yeej sib txawv rau txhua cov yeeb nkab loj uas peb xav tau xov. Lub tshuab vuam nyob rau hauv ob txhais tes ntawm ib tug kws yeeb nkab welder ua hauj lwm ntawm tej yeeb nkab loj. Xaiv cov txheej txheem vuam kom zoo raws li cov khoom siv, txoj haujlwm, phab ntsa tuab, thiab kev siv zaum kawg yuav ua rau xaiv cov khoom siv vuam kom raug. Lub neej ntev muaj cov khoom siv vuam kom tau raws li ntau cov yeeb nkab vuam xav tau.
