Cov Txheej Txheem Ntau Lawm Ntawm 3PE Anti-corrosion Yeeb Nkab

Raws li cov qauv tsim ntawm cov kav xa dej los tiv thaiv corrosion, kev tiv thaiv corrosion ntawm cov kav hlau feem ntau siv cov txheej txheem tsim khoom ntawm kev ua haujlwm ntawm kev sib xyaw ua ke.
Tom qab txhua tus txheej txheem tau npaj tiav, raws li qhov yuav tsum tau muaj ntawm peb qhov sib txawv los tiv thaiv corrosion txheej rau kev tiv thaiv corrosion thickness nyob rau hauv cov kav dej los tiv thaiv corrosion, preheating kub ntawm cov yeeb nkab steel txheej thiab txheej txheej thickness ntawm txhua txheej ntawm anti-corrosion. corrosion txheej yuav tsum tau kho nyob rau hauv lem ntawm cov kab ntau lawm nrog rau cov yeeb nkab xeem seem. Kev tsim khoom tsuas yog ua tau tom qab tag nrho cov kev ntsuas ua tau raws li qhov yuav tsum tau ua.

• Kev tshuaj xyuas cov yeeb nkab steel

1. Ua ntej ua tiav, cov tsos ntawm cov yeeb nkab steel yuav tsum pom kev pom los ntawm cov neeg ua haujlwm txawj kom pom tias cov kav hlau steel puas muaj kev puas tsuaj loj, tawv tawv, tawg, dents thiab lwm yam tsis xws luag. Cov kav hlau tsis tsim nyog siv tsis tau, thiab cov tsis tsim nyog tau raug cim thiab xa rov qab.
2. Yog hais tias lub qhov ncauj ntawm cov yeeb nkab threaded yog tiaj tus, nws yuav tsum tau muab sib dhos thiab kho raws sijhawm. Yog tias kho tsis tau, nws yuav tsum tau ua pauj.

• Kev tshem tawm xeb ntawm cov yeeb nkab fittings

1. Ua ntej, siv cov yeeb nkab grabber los thauj cov yeeb nkab steel uas yuav tsum tau tiv thaiv corrosion mus rau sab saum toj yeeb nkab platform ntawm cov kab ntau lawm, thiab siv lub tshuab hluav taws xob hluav taws xob los preheat rau sab nrauv ntawm cov yeeb nkab steel kom tshem tawm cov dej noo, roj. , impurities, thiab lwm yam nyob rau saum npoo ntawm cov yeeb nkab steel, uas yog qhov tsim nyog rau kev txhim kho cov xeb tshem tawm zoo ntawm cov yeeb nkab steel nto.
2. Cov yeeb nkab steel yuav tsum tau xeb los ntawm PW-380 steel yeeb nkab tua blasting tshuab. Ua ntej cov yeeb nkab steel nkag mus rau hauv chav tua blasting, cov yeeb nkab taub hau plugs ua los ntawm cov roj hmab los yog cov sponges tuab yog ntsaws rau ntawm ob qho kawg ntawm cov yeeb nkab steel qhov ncauj.
3. Tom qab ua tiav qhov pretreatment, tag nrho cov xeb, roj, oxide nplai, thiab lwm yam yuav tsum tau muab tshem tawm.
4. Txheeb xyuas qhov chaw sab nrauv ntawm txhua cov yeeb nkab steel, thiab siv cov txheej txheem tsim nyog los polish qhov chaw tsis xws luag uas yuav ua rau cov ntsiab lus to coating. Lub thickness ntawm phab ntsa tom qab sib tsoo yuav tsum tsis txhob tsawg tshaj li tus nqi teev. Tshem tawm lossis kho cov kav hlau uas muaj qhov tsis xws luag.
5. Rau cov kav hlau uas tsis tsim nyog rau kev tshem tawm xeb, lawv yuav tsum tau muab tshem tawm ntawm txoj kab hauv lub sijhawm, cov khoom parabolic hauv cov yeeb nkab yuav tsum tau muab tshem tawm, thiab rov qab mus rau cov kab ntau lawm kom tshem tawm xeb dua.

• Kev kho plua plav ntawm qhov chaw ntawm cov yeeb nkab steel

1. Tom qab cov yeeb nkab steel raug tua blasted thiab xeb-tshem tawm, cov khoom siv kho plua plav yog siv los ua kev kho mob theem nrab ntawm cov yeeb nkab steel ua ntej cov txheej txheem tom ntej ntawm epoxy hmoov high-voltage electrostatic txau kom tshem tawm cov hmoov xeb thiab hmoov av nyob rau sab nrauv ntawm cov yeeb nkab steel.
Siv epoxy hmoov txheej hauv 4 teev. Yog tias nws dhau 2 teev lossis xeb tshwm rau ntawm cov yeeb nkab steel, qhov kev kho saum npoo yuav tsum rov ua dua.
2. Ntxuav cov plua plav hauv lub tshuab nqus tsev twj tso kua mis tsis tu ncua kom tsis txhob muaj ntau dhau thiab cuam tshuam rau cov plua plav tshem tawm.
3. Tom qab pib lub tshuab tshem tawm cov plua plav, xyuas cov kev ua haujlwm ntawm cov kiv cua induced tsis tu ncua.
4. Lub tshuab tshem tawm plua plav yuav tsum tau khaws cia raws sijhawm kom ntseeg tau tias kev ua haujlwm zoo li qub.
5. Ua ntej los tiv thaiv corrosion, xyuas cov plua plav kho ntawm cov yeeb nkab steel yam tsawg ib teev ib zaug.

• Preheating ntawm steel yeeb nkab

1. Cov yeeb nkab steel tom qab kev kho plua plav yuav tsum tau preheated ua ntej epoxy hmoov txheej.
2. Txheeb xyuas cov dej theem nruab nrab ntawm lub pas dej ua ke
3. Raws li kev pub noj ceev ntawm cov kav hlau steel ntawm qhov sib txawv diameters thiab cov cua sov predetermined stability, cov zis fais fab nqi ntawm qhov nruab nrab zaus cua sov thaum lub sij hawm tsim khoom yog txiav txim siab.
4. Siv cov ntsuas kub siab tshaj plaws los ntsuas qhov kub ntawm cov yeeb nkab steel thaum lub sij hawm preheating los txhim kho qhov tseeb ntawm qhov ntsuas.

• Epoxy hmoov dov los yog txau

• Adhesive txheej thiab polyethylene winding

1. Cov txheej txheem ntawm cov nplaum yuav tsum tau nqa tawm thaum lub sij hawm epoxy hmoov gelling txheej txheem.
2. Thaum siv cov txheej txheem sab winding, xyuas kom meej tias cov polyethylene ntawm qhov sib tshooj thiab cov polyethylene ntawm ob sab ntawm lub vuam yog dov thiab compacted, thiab tiv thaiv cov polyethylene nto los ntawm crushed.
Tom qab cov txheej txheem tiv thaiv corrosion ntawm cov dej txias txias steel yeeb nkab ua tiav, nws yuav tsum tau txias thiab kho raws sijhawm. Qhov saum npoo ntawm txheej tiv thaiv corrosion ntawm cov yeeb nkab los tiv thaiv corrosion tuaj yeem ua kom txias hauv chav dej txheej txheej. Kev ua kom txias yog nqa tawm hauv theem.
