Astm Standard St37 Hollow Tube Square 2.5 Nti Galvanized Steel Tubing
Galvanized square yeeb nkab, tseem hu ua galvanized steel yeeb nkab, muab faib ua kub dip galvanized thiab hluav taws xob galvanized ob, kub dip galvanized galvanized txheej tuab, nrog txheej txheej, muaj zog adhesion, kev pab lub neej ntev thiab lwm yam zoo. Tus nqi ntawm electrogalvanizing yog tsawg, qhov saum npoo tsis du heev, thiab nws cov corrosion kuj yog qhov phem dua li cov kav dej kub-dip galvanized.
Cov yeeb nkab txias galvanized: galvanized yeeb nkab txias galvanized yog hluav taws xob galvanized, galvanized tus nqi tsawg heev, tsuas yog 10-50 grams ib square meter, nws tus kheej corrosion kuj txawv ntau dua kub galvanized yeeb nkab. Tsis tu ncua galvanized yeeb nkab ntau lawm nroj tsuag, kom zoo, feem ntau tsis siv hluav taws xob galvanizing (txias plating). Tsuas yog cov lag luam me nrog cov khoom siv tsis siv neeg siv hluav taws xob galvanizing, tau kawg, tus nqi kuj pheej yig.
Kub-dip galvanized yeeb nkab
Cov hlau molten reacts nrog cov hlau matrix los tsim cov txheej txheem alloy, kom cov matrix thiab txheej sib xyaw ua ke. Kub dip galvanizing yog ua ntej pickling cov yeeb nkab steel, thiaj li yuav tshem tawm cov hlau oxide nyob rau saum npoo ntawm cov yeeb nkab steel, tom qab pickling, los ntawm ammonium chloride los yog zinc chloride aqueous tov los yog ammonium chloride thiab zinc chloride tov aqueous tov tank rau tu, thiab ces mus rau hauv lub kub dip plating tank. Kub dip galvanizing muaj qhov zoo ntawm txheej txheej, muaj zog adhesion thiab lub neej ua haujlwm ntev. Feem ntau ntawm cov txheej txheem nyob rau sab qaum teb tau txais cov txheej txheem zinc ntxiv ntawm galvanized siv ncaj coil yeeb nkab.
Cold galvanized yeeb nkab
Txias galvanized yog hluav taws xob galvanized, galvanized tus nqi tsawg heev, tsuas yog 10-50g / m2, nws tus kheej corrosion kuj txawv ntau dua kub galvanized yeeb nkab. Tsis tu ncua galvanized yeeb nkab manufacturers, thiaj li yuav ua kom zoo, feem ntau tsis siv hluav taws xob galvanizing (txias plating). Tsuas yog cov lag luam me nrog cov khoom siv tsis siv neeg siv hluav taws xob galvanizing, tau kawg, lawv cov nqi kuj pheej yig. Yav tom ntej, cov kav dej txias galvanized tsis pub siv los ua cov kav dej thiab cov kav dej.
Kub-dip galvanized steel yeeb nkab
Cov kev cuam tshuam ntawm lub cev thiab tshuaj lom neeg tshwm sim ntawm cov hlau raj substrate thiab molten da dej los tsim cov zinc-hlau alloy txheej nruj nrog corrosion kuj. Cov txheej txheej alloy yog kev sib xyaw nrog cov zinc txheej ntshiab thiab cov yeeb nkab steel matrix. Yog li ntawd, nws cov corrosion kuj muaj zog.
Tom qab txoj kev loj hlob ntawm kub galvanized steel yeeb nkab nyob rau hauv lub 1960s mus rau 1970s, cov khoom zoo tau zoo heev txhim kho, 1981 txog 1989 tau muab tsub lub metallurgical Ministry ntawm high-zoo khoom thiab lub teb chaws nyiaj puav pheej, ntau lawm kuj nce ntau xyoo, 1993 cov zis ntau tshaj 400,000 tons, ntau tshaj exported Asia, ntau tshaj 19090 tons, exported Asia. Teb chaws Africa, Tebchaws Asmeskas, Nyiv, Lub Tebchaws Yelemees thiab cheeb tsam. Cov kav dej kub-dip galvanized feem ntau yog siv los ua cov kav dej thiab cov kav dej, thiab cov kev qhia tshwj xeeb yog + 12.5 ~ + 102 hli. Tom qab xyoo 1990, vim lub xeev tau mloog zoo rau kev tiv thaiv ib puag ncig, kev tswj hwm kev lag luam muaj kuab paug ntau dua thiab nruj dua, "peb cov khib nyiab" tsim los ntawm kev tsim cov kav dej kub-dip galvanized yog qhov nyuaj los daws, ua ke nrog kev txhim kho sai ntawm stainless hlau welded kav, PVC kav thiab cov kav dej sib xyaw, nrog rau cov ntaub ntawv siv cov yeeb nkab hauv lub xeev. txwv tsis pub, ua rau txoj kev loj hlob ntawm kub-dip galvanized welded kav dej tau zoo heev cuam tshuam Beam thiab txwv, kub dip galvanized welded yeeb nkab tom qab tsim maj mam.
Cold galvanized steel yeeb nkab
Cov txheej zinc yog txheej txheej hluav taws xob, thiab cov zinc txheej yog nws tus kheej txheej nrog cov yeeb nkab steel matrix. Cov zinc txheej yog nyias, thiab cov zinc txheej tsuas yog txuas nrog cov hlau raj matrix thiab yooj yim rau poob. Yog li ntawd, nws cov corrosion kuj tsis zoo. Hauv cov tsev nyob tshiab, nws raug txwv tsis pub siv cov kav dej txias galvanized ua cov kav dej.
Daim ntawv thov
Vim tias galvanized square yeeb nkab yog galvanized ntawm cov yeeb nkab square, yog li daim ntawv thov ntau yam ntawm galvanized square yeeb nkab tau nthuav dav heev dua li cov yeeb nkab square. Nws yog tsuas yog siv nyob rau hauv daim ntaub thaiv phab ntsa, kev tsim kho, machinery manufacturing, steel siv tej yaam num, shipbuilding, hnub ci zog tiam bracket, steel qauv engineering, fais fab engineering, fais fab nroj tsuag, kev ua liaj ua teb thiab tshuaj machinery, iav kab hlau rhuav phab ntsa, tsheb chassis, tshav dav hlau thiab hais txog.
