Flanges yog qhov yooj yim yooj yim cov twj uas tau siv ua tiav rau cov ntawv thov kev siab siab piping siab. Lawv tau to taub zoo, txhim khu kev qha, raug nqi, thiab npaj tau los ntawm ntau yam khoom siv. Tsis tas li ntawd, lub sijhawm-nqa lub peev xwm ntawm flanges yog qhov tseem ceeb piv rau lwm cov tshuab txuas tshuab. Qhov no yog qhov tseem ceeb rau cov kab ke uas muaj kev siv yeeb nkab-taug kev los yog tom qab kev kub thiab siab hloov chaw). Flanges tuaj yeem tsim los ua kom tau raws li ntau yam ntawm cov ntawv thov yuav tsum muaj xws li high-kub thiab corrosion tsis kam.

Kev phais

Yeeb nkab flanges tau yaug lossis cov chaw tiaj uas sib txuas rau cov yeeb nkab uas lawv xa. Ob qho ntawm cov chaw no muaj kev sib koom ua ke ntawm bolts, collars, nplaum lossis versds.

Feem ntau, flanges yog txuas rau cov kav dej ntawm vuam, brazing, lossis xov.

Vuam koom nrog cov ntaub ntawv los ntawm melting lub workpieces thiab ntxiv cov khoom siv tsav tsheb. Rau cov muaj zog, kev kub siab sib txuas ntawm cov ntaub ntawv zoo sib xws, vuam nyooj yuav yog txoj kev sib txuas zoo ntawm flange. Feem ntau cov yeeb nkab flanges yog tsim kom muaj welded rau kav dej.

Brazing yog siv los koom nrog cov ntaub ntawv los ntawm melting ib tug muab tub lim hlau uas ua rau cov khoom sib txuas. Txoj kev no tsis yaj ua haujlwm los yog ntxias Thermal distortion, cia rau kev ua kom nruj thiab ua ke huv si. Nws tseem tuaj yeem siv los txuas cov khoom siv tsis sib xws li cov hlau thiab cov khoom siv hlau.

Xov tau thov rau flanges thiab cov kav dej kom tso cai rau cov kev sib txuas kom raug ntsia hlau ua ke ua ke nrog cov txiv ntoo kom zoo sib xws los yog bolts.

Thaum cov qauv ntawm kev txuas tuaj yeem yog qhov txawv txav, muaj lwm yam kev txiav txim siab tseem ceeb dua rau cov flange xaiv. Cov ntsiab lus muaj cov neeg yuav khoom yuav tsum xav txog ua ntej yog cov Flange cov specars lub cev, ntaus, khoom siv, tsim nyog feem ntau haum rau daim ntawv thov.
