Galvanized seamless yeeb nkab

Cov hauv qab no yog cov kev qhia dav dav rau Galvanized seamless kav, npog lawv cov nta, daim ntawv thov cov txheej txheem tshwj xeeb, kev ua lag luam zoo nkauj:

1.Definition thiab qauv

Galvanized Seamless Steel Kav yog cov kav dej uas ib zinc {}}}}}}}}}}}- dip galvanizing txheej txheem. Nws cov tub ntxhais yog ua los ntawm cov hlau hlau (xws li Q195, Q215, Q235, thiab lwm yam) ove} Corrosion kev ua yeeb yam ntawm cov khaubncaws sab nraud.

2.Core Cov yam ntxwv

• Muaj zog corrosion: lub zinc txheej cais cua, dej thiab lwm yam tshaj tawm, nthuav tawm lub neej pabcuam ntau tshaj 20 xyoo;
• Lub zog siab thiab hnav tsis kam: cov khoom siv hauv paus yog kho los ntawm cov txheej txheem dov lossis txias kos duab, thiab lub zog compressive tau nce ntau zaus.
• High - kub yoog tau: nws tuaj yeem ua haujlwm ruaj khov nyob rau hauv high-} pipelines) thiab tsis muaj feem rau deformation;
• Kev tsim kho yooj yim: du nto, yooj yim txiav, Weld thiab txuas.

1.key kauj ruam

Nto Kho:Pickling yog nqa tawm kom tshem tawm cov oxides thiab roj stains nyob rau saum npoo ntawm cov yeeb nkab steel kom ntseeg tau tias cov nplaum ntawm zinc txheej;

Kub - dip Galvaning

Tswj kub: Qhov ntsuas kub: qhov ntsuas kub ntawm cov kua dej zinc yuav tsum tau ruaj khov ntawm 450-4 qib;

Zinc Kev Tiv Thaiv: Kho raws li tuab ntawm cov yeeb nkab phab ntsa (feem ntau yog 1-5 feeb) kom tsis txhob plam plinc txheej;

Txias thiab teeb tsa: Kho lub zinc txheej los ntawm dej txias lossis cua txias.

2.Process hom

Kub - dip galvanizing hom:Haum rau loj - txoj kab uas hla (txheej uas hla (}} 610 hli), nrog tus nqi qis thiab kev tiv thaiv tsawg;

Kab mob plating txias:Siv rau me me - diam precision leeg, nrog cov khaub ncaws hnav thiab ci ntsa iab.

3.Specification rau Zin Txheej Txheej Thickness

Raws li kev lag luam qauv (xws li ASTM A53).

1.Txoj kev lag luam thiab cov nroog Engineering

Cov qauv txheej txheem kev txhawb nqa (txuas hniav, ntaiv), cov dej ntws hauv av, ru tsev tawm;

Cov kav dej sov (cov kav dej kub (siab - kub ua rau ntau dua lossis sib npaug rau 100 degree).

2.Urgy thiab tshuaj enchering

Roj / roj hloov hluav taws xob pipelines (siab {{0} qib ib puag ncig, siab dua lossis sib npaug rau 20mpa);

Tshuaj lom neeg cov khoom (resistant rau kua qaub thiab alkali corrosion, xws li acid ntxuav tso tsheb hlau luam, reactor pipelines).

3.Mechanical Raug Thiab Tsheb Thauj Mus Los

Lub tsheb chassis, tso pa tawm;

Tsuas yog Machinery txhawb nqa, cov kav dej hauv av.

Cov laj thawj rau kev to taub yuam kev plating:

Cov roj roj stains lossis oxide teev rau saum npoo;

Excessive iron content in the zinc liquid (>0.05%) lossis kub hloov pauv;

Tsis raug cai siv lub kaum sab xis ua rau npuas ua npuas.

Kev daws:

Txhim kho pickling thiab sandblasting pretreatment;

Tsis tu ncua ntsuas cov ntawv sib xyaw ntawm cov xee zinc thiab tswj cov ntsiab lus impurity.

Cov lus tshwj xeeb:

Txheej hauv txoj kab no: 10-720mm (feem ntau 21.3-610mm)

Phab Ntsa Thickness: 1.5-75mm (piv txwv, phab ntsa tuab ntawm DN32 kav ntau dua los yog sib npaug ntawm 2.5mm)

Ntev: Taag ntev 4-12 meters (customizable).

Galvanized Seamless Steel Kav, los ntawm kev sib xyaw ntawm cov khoom siv hluav taws xob thiab zinc tsis yooj yim ntawm kev tsim kho cov khoom siv, thiab tau dhau los ua cov tub ntxhais kev tsim kho, lub zog thiab tshuab. Nws ua tau zoo yog nyob ntawm cov thev naus laus zis raug
