Ntau yam fittings thiab nws cov nyhuv on sis nyob rau hauv qhuav ntawm

Lub ntsiab lus ntxawg qauv thiab classifications nyob rau hauv industrial qhuav yog heev loj, nws yog muaj tshwj xeeb acutely ntawm cov kev tshuam ntawm kev tsim kho thiab metallurgy.

Ntau yam fittings yog lub faib feem ntau-siv ntawm txias thiab kub kuav los tiag steel rods los yog puas cov ntaub ntawv, uas yog nyob rau hauv ib tug tej yam ntau yam ntawm lub xeev metallurgical los yog lwm yam kev qhauj. Ntau yog feem ntau yog muaj li raws li cov uas twb muaj lawm ntxawg thiab cov kev cov ntaub ntawv, uas txiav txim seb tus gradation yam ntxwv khej thiab zoo rods. Nws yog tsim los rau rational xaiv ntawm qhov cuab lub zog rau lub dag lub zog yam ntxwv thiab txo pov tseg thaum lub sij hawm siv thiab installation tej hauj lwm. Qhov no yog vim lub fact tias txawm cov hlau zoo tib yam zoo St3, St5 - ib qho kim cov khoom, thiab nws tuaj nyob puv nkaus invalid.

Lub keeb kwm ntawm lub sij hawm thiab nws cov kev siv tshwj xeeb tshaj yog

Lub sij hawm "gauge fittings" daim xwb nyob rau hauv cov kev puag ncig uas tsim engineers, ntau lawm engineers , thiab lwm yam kev ua hauj lwm ntawm qhov kev siv sector thiab muaj qhauj-producers ntawm no structural khoom. Nws yog maloupotrebimoy rau hauv dav siv. Lub hauv paus chiv keeb ntawm cov kev qhia yog yuam ua hauj lwm kom qiv lub Fabkis lo lus assortiment, uas nyob rau hauv lub chav kawm ntawm adaptation mus rau lub Lavxias teb sab lus lawm mas tej nta xam qhovkev tsuas yog tej nqe lus yog siv nyob rau hauv ib tug kev ib puag ncig.

Ntsiab nta thiab sib txawv ntawm cov khoom mix

Tus qauv ntawm tag nrho cov assortments yuav tau muab faib mus rau hauv me thiab zoo li tus, nyob rau hauv thawj embodiment yog qhia nrog rau ntau yam yooj yim ib daim ntawv ntawm qhov cuab lub zog rau detailing nws cov nta, whereas nyob rau hauv lub thib ob embodiment, faib yog ua rods nyob rau hauv lawv npaj daim ntawv thov (weldable, termouprochnonnaya fittings thiab thiaj li nyob). Classic rau lub Lavxias teb sab Federation assortment ntawm fittings (GOST 5781-82 nws qhov chaw) combines tag nrho cov saum toj no nta thiab qhia qhov tsim nyog tsis nyob rau hauv lub feem ntau yooj yim rau daim ntawv. Nyob rau hauv lub xeev no standard qhia txog cov hauv paus ntsiab lus ntawm conformity reinforcing steel (ib tug hlau thiab ib tug pas nrig) xav tau muab tso rau raws li qhov nws txiav txim tolerances khoom losses. Nyob rau hauv kev sib piv nrog rau cov pa zoo tagnrho mix, uas yuav muaj ib tug tag nrho cov numeric co txawv profile ntoo khaub lig seem thiab qhov ntev ntawm lub pas nuv ntses, tam sim ntawd tso tawm kom pom xwb rationally xaiv ntau thiab tsawg pab. Lawv tsis pub ob leeg ntev li load rau lub Cheebtsam vim ntev li tus ntoo khaub lig-sections thiab lawv tus kheej nyhav thiab tseem ceeb tshaj tau ntawm cov ntaub ntawv thiab muab tsuas tsawg heev deadweight tsis thaum lub sij hawm tus txheej txheem ntawm kev tsim kho. Nyob rau tib lub sij hawm, ntau yam muaj qhauj yuav ua tau cov khoom tsim los ntawm lawv rau tib lub technical tej yam kev mob, noj mus ua nyiaj nws cov hom phiaj. Nyob rau hauv kev no siv rau pas nrig thiab hlau cov khoom ua los ntawm puas cov ntaub ntawv thiab cov coj daim ntawv thov ntawm cov tswv yim pom zoo.

Cov ntaub ntawv los ntawm GOST 5781-82

Nta ntawm kev siv ntawm fittings thiab sib tov ntawm high-sawv lub tsev

Txawm tias muaj tseeb hais tias cov uas duav txhua yam ntawm tus steel qhov cuab lub zog yog tsis heev uas nws kim heev (tsis zoo li lwm yam steel khoom), nyob rau hauv kev tsim kho kev lag luam ua kev reinforced monolithic lug nws yog yuav luag irreplaceable. Tom qab tag nrho, qhov no hom ntawm kev tsim kho ntawm multi-storey thiab high-sawv vaj tse yuav tas mus li txoj kev txhim kho ntawm knitted los yog welded ncej thiab nws embedment. Nws tau txais tag nrho cov tseem ceeb heev qhov tseem ceeb ntawm cov txhawj xeeb nyob rau hauv cov lug: tensile, compression, dabtsi yog khoov, cua deeg, thiab yog hais tias tsim nyog - seismic yam, kuj tiv thaiv tsis tsim nyog qhia tawm tej kab nrib pleb hauv pob zeb ua lub tsev hais. Attendance tseem ceeb ntawm tej qauv xa mus rau lub chaw nyob rau hauv coils los yog packs nrog rods (nyob ntawm seb lub lub cheeb ntawm lub valve), txhua tus uas muaj nws tus kheej daim ntawv lo. Thaum lub qhov chaw ntawm unloading ntawm cov ntaub ntawv uas nws yog los txais tos, nrog daim ntawv rau cov uas txib yog chaw tsim tshuaj paus los yog chaw muag khoom, nyob qhov twg lub teeb gauge fittings.

Tus nqi ntawm cov kev cai nyob rau hauv lub cheeb tsam ntawm metallurgy khoom thiab kev tsim kho

Hoobkas ceg rau zus tau tej cov pob zeb khoom, uas tsim kev tsim kho steel nyiaj txais muas tsev paub meej nrog steaming txoj kev thiab kev co, muag lawv cov khoom rau cov tuam txhab uas tsim lub tsev ntawm precast qhob ntsiab. Ua tau hauj lwm ntawm manufacturers thiab neeg ua hauj lwm ua hauj lwm nyob rau hauv cov cheeb tsam no yog tsis tau tsis txaus nomenclature ntawm steel cov ntaub ntawv, thiab lub hauv paus rau lawv lawm thiab yog ib tug gauge valve. Nyob rau hauv lub teb ntawm kev cai, standardization thiab kev koom ua ke ntawm tej khoom zoo xws li cov technical ntaub ntawv assumes lub luag hauj lwm ntawm unifying tau los ntawm cov uas nqa lub cev sis ntawm qhov uas tsis yog-contiguous chaw ntawm lawm.
