SS400 ERW Tube

 

SS400 kuj welded yeeb nkab yog Japanese txheem carbon structural steel yeeb nkab, sib npaug rau Suav tus qauv Q235B, nrog lub zog tensile txog li 400 MPa. Vim nws cov ntsiab lus carbon tsawg, nws muaj lub zog nruab nrab, zoo plasticity, thiab toughness, nrog rau cov yam ntxwv uas ua rau nws yooj yim rau txheej txheem thiab vuam. Nws yog dav siv nyob rau hauv ntau lub tsev tsim thiab engineering manufacturing vim cov yam ntxwv.

Anti-corrosion Coatings Rau Ss400 Resistance Welded Pipes

1. Petroleum Asphalt Anti-corrosion Txheej

Petroleum asphalt txheej muaj cov roj av asphalt txheej, cov ntaub iav siv dua tshiab, thiab cov ntaub thaiv sab nrauv PVC. Nws muaj kev ua tau zoo ntawm cov dej tsis zoo, yog tus nqi-zoo, muaj huab cua tsis zoo, thiab ua raws li ntau qhov chaw. Nws daim ntawv thov yog yooj yim, thev naus laus zis yog paub tab, thiab nws yog dav siv rau kev tiv thaiv hlau corrosion. Txawm li cas los xij, cov roj av asphalt coatings muaj qhov tseem ceeb ntawm qhov kub thiab txias: lawv soften ntawm qhov kub thiab txias, yaj yooj yim, ua nkig ntawm qhov kub thiab txias, tawg yooj yim nyob rau hauv kev cuam tshuam, muaj hnub nyoog sai, muaj kev cuam tshuam rau cov kab mob corrosion, thiab muaj kev ua haujlwm siab thiab ib puag ncig tus nqi thaum tsim khoom thiab faus. , txwv tsis pub lawv siv nyob rau hauv cov nroog uas muaj neeg coob coob.

2. Epoxy Coal Tar Anti-corrosion Txheej

Epoxy thee tar muaj epoxy resin thiab thee tar asphalt, rhuab thiab tov nrog cov kuab tshuaj, xeb inhibitors, muab tub lim, thiab cov tshuaj tua kab mob. Nws muaj cov dej tsis zoo, tshuaj tiv thaiv, tiv thaiv corrosion, thiab zoo adhesion zog, mechanical zog, thiab rwb thaiv tsev zog. Nws tuaj yeem siv rau ob qho tib si ambient thiab txias txias, ua rau nws yooj yim dua los tsim piv rau roj av asphalt thiab thee tar asphalt. Txawm li cas los xij, epoxy coal tar coatings yuav tsum tau kho lub sijhawm ntev dua tom qab thov kom ua tiav qhov kev thauj khoom tsawg kawg nkaus. Thaum lub sij hawm kho, cua, nag, thiab Frost tuaj yeem cuam tshuam rau saum npoo ntawm cov txheej tiv thaiv corrosion, ua rau nws tsis tuaj yeem siv rau qhov kub thiab txias.

3. Epoxy Resin Powder Anti-corrosion Txheej

Epoxy hmoov anti-corrosion txheej yog siv los ntawm electrostatic spraying mus rau pre-kho thiab pre-rhuab yeeb nkab nto, qhov uas nws undergoes ib tug curing cov tshuaj tiv thaiv los tsim ib tug ntom anti-corrosion txheej. Cov txheej no muaj kev tiv thaiv corrosion zoo heev, ib puag ncig muaj kuab paug tsawg, thiab ntau qhov zoo: (1) nws ua haujlwm nyob rau hauv qhov kub ntawm 100 degree rau -60 degree, dav dua PE; (2) nws adheres zoo rau cov yeeb nkab thiab muaj zoo cathodic disbondment kuj; (3) nws muaj kev cuam tshuam zoo, toughness, thiab kub tsis kam, nrog kev puas tsuaj tsawg heev thaum vuam; (4) nws muab cov dej tsis zoo thiab hluav taws xob rwb thaiv tsev; (5) kev puas tsuaj yog yooj yim nrhiav thiab kho. Txawm li cas los xij, cov teeb meem tseem ceeb suav nrog cov yeeb yaj kiab nyias nyias, ua rau muaj kev puas tsuaj rau sab nraud xws li pinholes, cov khoom siv thev naus laus zis siab, cov cuab yeej nyuaj, thiab cov teeb meem hauv kev tswj xyuas kev tsim kho.

4. Polyethylene Anti-corrosion Txheej

Polyethylene (PE) muaj cov khoom zoo ntawm lub cev thiab cov khoom siv xws li kev cuam tshuam thiab kev ua haujlwm siab. Nws kuj muaj ntau yam kub ntawm daim ntawv thov (nplaum hom: 60 degree rau -40 degree; shrink type: 80 degree rau -45 degree ). PE txheej yog siv dav hauv cov kav dej hauv thaj chaw txias xws li Western Europe. PE txheej yuav extrusion ntawm molten polyethylene mus rau steel yeeb nkab nto los tsim ib lub plhaub yas, muab kev tiv thaiv corrosion. Nws tseem hu ua polyethylene thermoplastic txheej los yog jacketing.
