Qhov sib txawv ntawm cov yeeb nkab khoov thiab lub luj tshib

Piping Bend yog dab tsi?

Cov yeeb nkab khoov yog lub ntsiab lus dav dav rau qhov hu ua piping li "offset" - kev hloov pauv ntawm cov kav dej. Kev khoov feem ntau txhais tau tias tsis muaj dab tsi ntau dua li qhov "khoov" - kev hloov pauv ntawm cov kav dej (feem ntau yog vim li cas qee qhov tshwj xeeb) - tab sis nws tsis muaj qhov tshwj xeeb, engineering txhais raws li kev taw qhia thiab qib. Khoov feem ntau yog tsim los (siv lub tshuab dabtsi yog khoov) ntawm qhov chaw thiab haum rau qhov xav tau tshwj xeeb. Khoov yog feem ntau yog ua los ntawm kev siv lub tshuab dabtsi yog khoov (kub dabtsi yog khoov thiab txias dabtsi yog khoov) ntawm qhov chaw thiab haum rau ib qho kev xav tau tshwj xeeb. Kev siv khoov yog kev lag luam vim nws txo tus naj npawb ntawm cov khoom siv kim.

Piping luj tshib yog dab tsi?

PIPING ELBOW, ntawm qhov tod tes, yog ib qho tshwj xeeb, tus qauv, kev tsim kho khoov ua ntej ua ib qho spool piece (raws li ASME B 16.9) thiab tsim los yog screwed, flanged, los yog welded rau cov kav dej nws yog txuam nrog. Lub luj tshib tuaj yeem yog 45 degrees lossis 90 degrees. Kuj tseem muaj peev xwm tsim lub luj tshib, txawm tias feem ntau yog categorized li "luv vojvoog" lossis ntev vojvoog".

Cov yeeb nkab khoov feem ntau muaj qhov tsawg kawg yog khoov vojvoog ntawm 1.5 npaug ntawm cov yeeb nkab vojvoog (R). Yog tias lub vojvoog khoov no tsawg dua 1.5R, nws hu ua Luj tshib. Kev xa mus rau txhua tus qauv thoob ntiaj teb / kev lag luam yuav tsum tau taug qab. 1.5, 3 thiab 4.5 R yog feem ntau bending radii hauv kev lag luam.

Cov yeeb nkab khoov feem ntau ntws zoo dua vim tias tsis muaj qhov tsis sib xws ntawm cov yeeb nkab sab hauv, thiab cov kua dej tsis hloov pauv sai.

Qhov yooj yim sib txawv ntawm lawv yog lub luj tshib luv dua li khoov, R=1D rau 2 D yog lub luj tshib Ntau tshaj 2D yog khoov. Nyob rau hauv cov txheej txheem ntau lawm, khoov txias tuaj yeem siv Bending Tshuab los khoov los ntawm kev npaj ua ncaj ncaj. Ib zaug ua tiav kuj tsis xav tau ob corrosion. Tab sis lub luj tshib xav tau cov neeg tsim khoom ua kom xaj, ua los tiv thaiv corrosion, kev txiav txim lub voj voog ntev. Lub luj tshib tus nqi siab dua li khoov. Tab sis tus nqi kev ua tau zoo yog ntau dua li khoov. Nws yog qhov paub zoo tias khoov tsis muaj cov txheej txheem anticorrosive yog ib qho yooj yim puas, tab sis tus nqi pheej yig yog li siv ntau heev hauv qee qhov kev thov uas tsis siab heev engineering.
