Yeeb Nkab Spools Fabrication

Qhov sib koom ua ke yog tsim los ntawm bolting ob txoj kev pluag rau ib leeg thiab sib khi lawv los ntawm kev siv ntau gaskets. Flanges feem ntau yog ua los ntawm txhuas, tooj dag, tooj dag lossis cov hlau. Cov khoom nyiam tshaj plaws rau cov ntawv thov flange dav yog cov tshuaj pleev cov pa roj carbon hlau. Ntxiv mus, flanges tuaj yeem foiled sab hauv nrog sib txawv hom ntaub. Feem ntau, cov khoom siv flange yog xaiv raws li cov khoom siv nrog cov yeeb nkab cov ntaub ntawv. Qhov kev xaiv xaiv no tau ua los tiv thaiv cov kev pheej hmoo galvanic tau. Cov khoom siv tsim nyog rau cov flanges yog txiav txim siab raws li ASTM A-182 tus qauv.

Qhov (socket) welded Tees yog tsim vim yog ATM ASME B16.11 tus qauv. Cov qauv kev ua kom zoo thiab txiav txim siab kom muaj qhov ntsuas kom muaj qhov kom muaj kub thiab kub thiab cov tshuab hluav taws xob thiab cov ntaub ntawv uas xav tau rau kev tsim cov Tees. Tsis tas li ntawd, B16.11 tus qauv tsuas yog pub rau cov carbon thiab cov hlau loj tagnrho. Lub qhov (socket) welded tees tuaj yeem tsim mus rau hauv peb pawg siab uas yog; Chav Kawm 3000, Chav Kawm 6000 thiab Chav Kawm 9000.

Cov cylindrical bulge tau muab tso rau qhov siv flange hauv huab cua zoo xws li; nce kub lossis siab nias cov cua nab. Cov flanges no yog welded rau cov kav dej lossis cov fittings los ntawm kev siv pob tw-vuam uas ua rau muaj tag nrho cov kev kho lub cev. Npleem-ntawm flanges kuj yog ntau yam siv vim lawv tus nqi qis. They do not require excessive surface finishing as weld necked flanges.

Flanges are the components that work as a connector between main pipes, valves or pumps. Qhov txiaj ntsig zoo tshaj plaws ntawm Flange siv yooj yim qhov yooj yim ntawm kev tu thiab tshuaj xyuas ntawm thaj chaw sib txuas los ntawm cov flanges. Flanges are usually produced by utilizing welding or screwing methods. Flange systems make a joint between different components.

Yog li no, kev txhim kho ntawm cov npleem-ntawm cov flanges yog qhov yooj yim dua. Txawm li cas los xij, lub zog ntawm cov flanges-ntawm flanges yog ob-feem peb ntawm weld necked flanges, hauv qab kev ntxhov siab vim ntws. Another disadvantage of the slip-on flanges is that it¡¯s impossible to fix a flange to the elbow or fix a flange to the tee because the end surface of the slip-on fittings is not straight. Qhov thib peb flange pab pawg yog lub qhov (socket) weld flanges. Cov flanges no tau siv rau cov kav dej me uas yuav tsum tau cog lus siab. Lub zog ntawm lub qhov (socket) weld flanges tawm tsam kev ntxhov siab sab hauv yog sib npaug ntawm cov flanges.

Qhov tshwj xeeb ntawm Flange hom yog ua tiav ntawm ASME B16.5 cov qauv. Yog li flanges tau raug cais raws li; weld neck, slip-on, socket weld, lap-joint, threaded blind. The weld necked flanges are easy to recognize. A cylindrical bulge with a gradually increasing radius is connected to the main hollow part.
