Kev piav qhia

12-Point flange screws, tseem hu ua Ferry Bolts, yog lub zog siab fasteners qhov twg flange txoj kab uas hla thiab lub taub hau thickness ntawm 12-Point Flange Screw yog sib npaug rau lub taub hau qhov ntev ntawm lub qhov (socket head cap screw), yog li tso cai rau 12-Point Flange Screw los ua ib qho kev hloov rau txhua daim ntawv thov uas hu rau lub qhov (socket head cap screw). Lub 12- taw tes lub taub hau tsim txhais tau hais tias cov ntsia hlau no tuaj yeem nruj nrog 12- lub qhov (socket) ntswj, uas tso cai rau lub zog siab dua los siv piv rau tus qauv sab hauv hex tsav lub taub hau taub hau ntsia hlau. Lub taub hau los yog ciaj ntswj loj yog tib yam li lub cev loj.

Peb 12 Point Flange Screws yog tsim nyob rau hauv nominal diameters li ntawm 1/8 "mus rau 3" (M3 - M80). Peb muab cov fasteners nyob rau hauv ob qho tib si USCS / Imperial thiab metric qhov ntau thiab tsawg. Peb cov fasteners ua tau raws li ASTM, ANSI, ASME, SAE, API, NAS, AN, MS, NACE, ISO, DIN, thiab KS cov qauv.

Nta

Kaum ob-point flange screws yog lwm lub taub hau tsim rau hex socket cap screws. Lub flange txoj kab uas hla thiab lub taub hau qhov siab yog tsim los kom haum rau daim ntaub ntawv thiab counterbored qhov npaj rau txheem hex socket cap screws.
Kaum ob lub ntsiab lus flange screws yog tsim nrog tib lub xov ntev raws li lub qhov (socket head cap screws) (2 npaug ntawm txoj kab uas hla + 1/2" yam tsawg kawg nkaus guaranteed threads).
Lub 12 taw tes lub taub hau tsim yog nruj nrog tus qauv kaum ob lub qhov (socket wrenches). Tus 12- taw tes tsim tso cai rau ntau dua torque los siv rau lub ntsia liaj qhov rooj thiab tshem tawm qhov sib npaug ntawm lub qhov (socket) uas tshwm sim nrog cov qauv hex qhov (socket).
Lub flange txoj kab uas hla thiab lub taub hau thickness ntawm 12 Point Flange Bolt yog sib npaug rau lub taub hau qhov ntev ntawm lub qhov (socket head cap screws). Qhov no tso cai rau Twelve Point Flange Bolt los hloov rau txhua daim ntawv thov tam sim no siv lub qhov (socket head cap) ntsia hlau.
Lub 12 taw tes tsim tso cai rau qhov style bolt kom nruj nrog 12 taw tes socket ciaj ntswj, tso cai rau lub zog siab dua los siv piv rau tus qauv sab hauv hex tsav lub taub hau taub hau ntsia hlau.
Lub zog siab dua thiab cov kabmob loj dua nyob rau hauv lub taub hau ntawm tus qauv tsim no muab cov txiaj ntsig ntxiv rau kev sib dhos dhau tus qauv hex taub hau hau screws. Tsis tas li ntawd, nws yog qhov zoo nkauj dua li tus qauv cap hex lossis lub qhov (socket head cap screws).

Cov khoom siv rau Flange Screws

Hlau
Hlau yog cov khoom siv dav siv rau flange screws vim nws lub zog thiab kav ntev. Nws tuaj yeem tiv taus kev ntxhov siab ntau thiab tiv taus hnav thiab tsim kua muag, ua rau nws zoo tagnrho rau kev siv hnyav.

Carbon Steel
Carbon steel yog hom hlau uas muaj cov ntsiab lus carbon ntau dua li cov hlau tsis tu ncua. Qhov no ua rau nws nyuaj thiab muaj zog dua, tab sis kuj nkig ntau dua. Cov pa roj carbon steel flange screws feem ntau siv rau hauv cov ntawv thov uas xav tau lub zog siab.

Stainless hlau
Stainless hlau yog lwm yam khoom siv rau flange screws. Nws muaj kev tiv thaiv corrosion zoo heev, ua rau nws tsim nyog siv rau hauv ib puag ncig uas cov bolts tuaj yeem raug ya raws lossis tshuaj lom neeg.

Txoj kev kho deg rau 12 Point Flange Screws

Dub (xiav)
Cov fasteners yuav tsum tau kho nrog dub yog muab tso rau hauv ib tug tov tank (145 ± 5 degree) uas muaj sodium hydroxide (NaOH) thiab sodium nitrite (NaNO2) oxidant, thiab rhuab rau oxidation. Cov txheej txheem no tsim ib txheej ntawm magnetic Fe3O4 (Fe3O4) zaj duab xis nyob rau saum npoo ntawm cov hlau fasteners, nrog ib tug tuab feem ntau xws li ntawm 0.6 mus rau 0.8μm, ua rau ib tug dub los yog xiav-dub. tsos.

Phosphating
Phosphating yog txheej txheem uas tsim cov phosphate tshuaj hloov dua siab tshiab zaj duab xis los ntawm cov tshuaj lom neeg thiab cov tshuaj electrochemical. Cov yeeb yaj kiab no, hu ua phosphating zaj duab xis, lub hom phiaj los muab kev tiv thaiv rau lub hauv paus hlau thiab tiv thaiv corrosion rau qee yam. Nws ua hauj lwm pab raws li ib tug primer ua ntej painting, txhim khu lub adhesion thiab corrosion kuj ntawm cov xim zaj duab xis. Tsis tas li ntawd, nws tuaj yeem siv los txo kev sib txhuam thiab muab lubrication hauv cov txheej txheem hlau ua haujlwm txias.

Kub Dip Galvanizing
Kub dip galvanizing yuav immersing tus neeg hlau, tom qab xeb tshem tawm, mus rau hauv ib tug zinc tov melted ntawm kub kub, kwv yees li 600 degree. Cov txheej txheem no ua rau saum npoo ntawm cov tswv cuab steel raug coated nrog ib txheej ntawm zinc. Lub thickness ntawm zinc txheej yuav tsum tsis pub tsawg tshaj 65μm rau nyias daim hlau tsawg tshaj li 5 hli, thiab tsis tsawg tshaj li 86μm rau tuab daim hlau 5 hli thiab saum toj no, zoo tiv thaiv corrosion.

DACROMET
DACROMET, ib qho tshiab anticorrosive txheej, yog tsim los ntawm zinc hmoov, txhuas hmoov, chromic acid, thiab dej deionized. Nws tsis pom cov teeb meem hydrogen embrittlement thiab muab qhov zoo tshaj plaws torque-preload sib xws.

Hluav taws xob Galvanizing
Kuj hu ua txias galvanizing, electrogalvanizing yuav siv electrolysis los ua ib tug uniform, ntom, thiab zoo-combined hlau los yog alloy deposition txheej ntawm lub workpiece nto. Zinc, vim nws pheej yig thiab yooj yim ntawm txheej, feem ntau yog siv rau electroplating los tiv thaiv steel qhov chaw tiv thaiv atmospheric corrosion thiab rau cov hom phiaj zoo nkauj.

Chrome Plating
Chrome plating feem ntau yog txhawm rau txhim kho qhov tawv tawv, kev zoo nkauj, thiab tiv thaiv xeb. Chromium plating pom zoo tshuaj stability, tiv thaiv alkalis, sulfides, nitric acid, thiab feem ntau cov organic acids. Txawm li cas los xij, nws yog soluble hauv hydrohalic acid (xws li hydrochloric acid) thiab kub sulfuric acid. Chromium plating yog nyiam dua nyiaj thiab npib tsib xee rau nws qhov kev xav tau ntev ntev thiab tsis kam hloov xim.

Zinc Impregnation
Hmoov zincizing thev naus laus zis suav nrog kev tso cov zincizing cov neeg ua haujlwm thiab cov hlau lossis hlau hauv lub qhov cub zincizing thiab cua sov rau li 400 degree. Qhov no ua rau cov zinc atoms nquag nkag mus rau hauv cov hlau lossis hlau los ntawm sab nraud, tsim cov zinc-hlau intermetallic compound lossis zinc txheej rau ntawm qhov chaw ntawm cov hlau. Nyob rau tib lub sijhawm, hlau atoms kis tau los ntawm sab hauv tawm, pab tsim cov txheej txheem.
