Cov yam ntxwv ntawm cov khoom

Integrated Flange Tsim:

Ib qho -daim flange nyob rau hauv lub taub hau ntsia liaj qhov rooj muab cov kabmob loj dua, faib lub siab sib npaug ntawm cov flange sib koom ua ke kom tsis txhob deformation thiab to.

Ntau hom khoom xaiv:

Cov pa roj carbon steel variants sib npaug tus nqi thiab lub zog yooj yim; alloy steel (8.8–12.9 qib) muaj siab tensile thiab tawm lub zog rau hnyav-load daim ntaub ntawv; Stainless hlau (304 / A2, 316 / A4) ua kom zoo corrosion kuj nyob rau hauv ib puag ncig hnyav.

Txhim khu kev ruaj ntseg Sealing Support:

Ua hauj lwm nyob rau hauv tandem nrog gaskets (rubber, hlau, PTFE) los ua ib tug nruj seal, haum rau siab -siab, siab - kub, los yog corrosive nruab nrab kis systems.

Ib qho yooj yim installation:

Tshem tawm qhov xav tau ntawm cov tshuab ntxhua khaub ncaws ntxiv, ua kom yooj yim sib dhos thiab txo qhov kev pheej hmoo ntawm cov khoom tsis sib haum.

Daim ntawv thov teb

Piping Systems:

Roj thiab roj pipelines, cov kav dej tshuaj, cov kav dej thiab cov kav dej, cov kav dej cua sov, thiab lwm yam.

Khoom siv:

Flange kev sib txuas hauv cov twj, li qub, compressors, turbines, boilers, thiab cov hlab ntsha siab.

Zog & Lub Zog:

Thermal fais fab nroj tsuag, nuclear fais fab nroj tsuag, cua turbines, thiab hydraulic / pneumatic systems.

Marine & Offshore:

Nkoj hull flanges, offshore platform piping, thiab cov khoom siv kho dej hiav txwv (preoritizing 316 / A4 lossis HDG txheej).

General Machinery:

Kev lag luam tshuab vaj tse, flange-mounted motors, thiab hnyav- cov khoom siv ua haujlwm sib koom ua ke.

Kev siv ceev faj

Kev teeb tsa:

Siv lub torque ciaj ntswj kom nruj bolts nyob rau hauv ib tug crisscross, symmetrical ib theem zuj zus (nyob rau hauv 2-3 theem) los xyuas kom meej zoo preload thiab tsis txhob sib sib zog nqus flange kev nyuaj siab.

Xaiv qhov tsim nyog ntsia liaj qhov rooj ntev: Xyuas kom 1-3 threads ntev tshaj lub txiv ntoo tom qab zawm, tsis txhob muaj kev koom tes tsis txaus los yog ntau tshaj xov protrusion.

Environmental Adaptation:

Rau qhov chaw ntub dej, sab nraum zoov, lossis corrosive ib puag ncig (xws li, tshuaj, marine), xaiv stainless hlau (316/A4) los yog kub-dip galvanized/Dacromet-coated carbon steel los tiv thaiv xeb thiab xeb.

Rau siab - kub (＞ 300 degree) lossis siab - siab (＞10 MPa) cov xwm txheej, xaiv cov hlau alloy steel 10.9/12.9 qib bolts nrog cov cua sov- tiv taus gaskets.

Kev tu:

Tsis tu ncua tshuaj xyuas rau loosening, corrosion, los yog gasket aging; rov kho los yog hloov cov khoom tam sim ntawd kom tsis txhob xau.

Ntxuav cov xov ua ntej kev teeb tsa kom tshem tawm cov roj, xeb, lossis cov khib nyiab uas yuav cuam tshuam rau qhov raug ua ntej.

Tseem ceeb Taboos:

Tsis txhob sib tov bolts ntawm qib sib txawv, cov ntaub ntawv, lossis kev kho saum npoo kom tiv thaiv lub zog tsis sib haum lossis galvanic corrosion.

High- lub zog bolts (10.9 / 12.9 qib) tsis tuaj yeem rov qab siv tau tom qab disassembly - qaug zog puas tuaj yeem cuam tshuam kev nyab xeeb ntawm cov qauv.

FAQ: Qhov txawv ntawm Flange Bolts thiab Standard Hex Bolts

Tus Qauv Tsim:

Flange bolts muaj kev sib xyaw flange (ua - hauv lub tshuab ntxhua khaub ncaws), thaum tus qauv hex bolts xav tau cais cov ntxhua khaub ncaws rau kev faib tawm siab.

Daim ntawv thov Focus:

Flange bolts yog tshwj xeeb rau flange pob qij txha, ua ntej kev sib khi thiab kev faib tawm siab; txheem hex bolts yog dav dav -lub hom phiaj rau tsis yog - flange kev sib txuas.

Sealing Performance:

Flange bolts 'cov kabmob loj dua thiab kev sib raug zoo nrog cov gaskets ua rau lawv tsim nyog rau kev xau- cov ntaub ntawv pov thawj; txheem hex bolts cia siab rau cov tshuab ntxhua khaub ncaws rau kev faib tawm siab.

Bearing Peev Xwm:

Lub flange tsim ntawm flange bolts muab zoo dua load dispersion, txo qhov kev pheej hmoo ntawm kev sib koom deformation piv rau tus qauv hex bolts nrog washers.

Tsim los ntawm 2005, peb lub tuam txhab tau hloov zuj zus tshaj li ob xyoo caum ntawm kev txhim kho txuas ntxiv mus rau hauv kev lag luam hauv cheeb tsam hauv kev lag luam fastener nrog kev ua haujlwm siab kawg -kom- xaus kev tsim khoom. Nrog rau cov txiaj ntsig txhua xyoo tshaj li RMB 130 lab, peb cov khoom lag luam suav nrog ntau hom kev lag luam los ntawm nruab nrab -ntau txog qib siab- kawg thiab tau muab faib thoob ntiaj teb
