Kev siv cov yas coated steel yeeb nkab

Yas-coated steel yeeb nkab, tseem hu ua yas-coated yeeb nkab, steel-yas composite yeeb nkab, yas-coated composite steel yeeb nkab, yog raws li cov yeeb nkab steel, los ntawm kev txau, dov, dipping,

Suction thiab lwm yam txheej txheem weld ib txheej ntawm cov yas los tiv thaiv corrosion txheej nyob rau hauv lub puab nto ntawm cov yeeb nkab steel los yog steel-yas composite steel yeeb nkab nrog ib tug yas anti-corrosion txheej welded rau sab hauv thiab sab nrauv.

Cov yas-coated steel yeeb nkab muaj zoo heev corrosion kuj thiab tsis muaj kev sib txhuam tsis kam.Epoxy resin coated steel yeeb nkab yog tsim rau cov dej thiab cov dej ntws, dej hiav txwv,

Kev thauj mus los ntawm cov dej sov, roj, roj thiab lwm yam xov xwm, PVC yas-coated steel yeeb nkab yog tsim rau kev thauj mus los ntawm cov dej ntws, dej hiav txwv, roj, roj thiab lwm yam xov xwm.

xa.

1,Scope ntawm kev siv:

1. Nws yog siv nyob rau hauv tshuaj lom neeg kev thauj mus los.

2. faus cov kav dej thiab cov kav dej ntawm cov xov hlau thiab cov kab.

3. Cov kav dej ua pa, dej thiab cov kav dej ntawm cov mines thiab cov mines.

4. Siv rau cov kav dej phwj hauv nroog.

5. Ntau hom kev siv dej ntws (xws li cov dej ntws hauv pej xeem, cov dej muaj dej), cov kav dej yas coated steel muaj cov khoom zoo heev los tiv thaiv corrosion.

Kev ua tau zoo, lub sijhawm tiv thaiv corrosion tuaj yeem ncav cuag 50 xyoo.

6, siv nyob rau hauv hluav taws pipeline dej system.

7. Kev xa dej thiab kev thauj mus los ntawm ntau lub tsev (tsim rau cov dej txias thiab dej kub hauv cov tsev so, tsev so, thiab cov chaw nyob hauv high-end).

2,Txheej txheem khiav:

1. Cov xim nkag mus rau hauv lub Hoobkas thiab ncaj qha nkag mus rau electrostatic txau tom qab dhau qhov kev tshuaj xyuas zoo, thiab rov qab mus rau cov chaw tsim khoom yog tias nws ua tsis tiav;

2. Tom qab cov yeeb nkab steel nkag mus rau hauv lub Hoobkas thiab dhau qhov kev soj ntsuam zoo, lub nozzle yog ua tiav.Ua ntej, lub nozzle burr thiab vuam seam yog hauv av (qhov siab ntawm qhov vuam bar tsis tuaj yeem tshaj

0.5 hli);

3. Tom qab lub nozzle tiav lawm, mus rau hauv pickling (qhov concentration ntawm pickling yuav tsum tsis txhob ntau tshaj 30% hydrochloric acid, tsau nyob rau hauv lub pickling tank rau ntau tshaj 3 feeb), thiab sandblasting thiab xeb tshem tawm yuav nqa tawm rau lub me me txoj kab uas hla;

4. Tom qab lub pickling tiav lawm, nws yuav nkag mus rau hauv phosphating.Nws yog ib qho tsim nyog yuav tsum muab cov yeeb nkab steel tom qab lub pickling rau hauv lub tank phosphating tam sim ntawd thiab tsau nws horizontally, thiab tom qab ntawd tshem tawm cov phosphating tank.Lub hom phiaj Nws yog los tsim ib txheej ntawm phosphating zaj duab xis rau saum npoo ntawm cov yeeb nkab steel, uas tsis tuaj yeem yooj yim oxidized nyob rau lub sijhawm luv luv thiab tsis txhob xeb dua.
