SSAW Welded Kav Rau Cov Khoom Siv Dej

SSAW welded kav nrog 3PE coating rau dej xa Txoj hauv kev nrug ntev ntawm kev siv roj, roj lossis roj refined, cov kav dej feem ntau yuav tsum tau faus hauv av. Thaum steel kav lossis yeeb nkab fittings yog nyob rau hauv kev sib cuag nrog cov av thiab dej, peb yuav tsum xav txog nws sab nraud anti-corrosion ...

SSAW welded kav nrog 3PE txheej rau dej xa

Nyob rau hauv ntev kev xa xov ntawm crude roj, natural roj los yog refined roj, lub raj dej feem ntau yuav tsum tau faus nyob hauv av. Thaum cov kav hlau los yog cov yeeb nkab ua rau sib txuas nrog cov av thiab dej, peb yuav tsum xav txog nws qhov kev tiv thaiv kev txhim kho sab nraud kom paub tseeb tias lub neej hauv tsev. Qhov peb txheej polyethylene (3PE / 3LPE) sab nrauv txheej txig ua qhov teeb meem no. Nws muaj kev kawm siab siab fusion ua ke nrog epoxy (FBE) txheej, ib txheej nplaum thiab ib txheej sab nrawm ntawm high-density polyethylene. Qhov peb txheej txheej txheej kuj muaj kev ywjpheej ua haujlwm tsis zoo, hnav, kua qaub, alkali thiab cathodic disbonding, thiab lwm yam.


Tshwj tsis yog hais los ntawm tus neeg yuav khoom, lub 3PE (tseem hu ua 3LPE) txheej yuav raug tsim thiab kuaj xyuas raws li EN EN DIN 30670: Polyethylene coatings rau steel kav thiab fittings.



Cov yeeb nkab muaj 3 txheej PE anticorrosion: Thawj txheej nrog epoxy hmoov (FBE> 100um), ob txheej nrog nplaum (ADVERTISEMENT), 170 ~ 250um, txheej txheej thib 3 nrog polyethylene (PE) 2.5 ~ 3.7 hli. 3PE anti-corrosion yog feem ntau siv cov txheej txheem los tiv thaiv corrosion, ntxiv rau 2PE, 2PP, 3PP, lawv cov txheej txheem tsim yog comparable tiam sis txawv cov khoom nyoos, qhov no los tiv thaiv corrosion yam ntxwv ntawm cov ntaub ntawv yooj yim, pheej yig yeeb nkab ua khoom lag luam niaj zaus concur tias deterioration

3PE anticorrosive steel yeeb nkab yam ntxwv:

1, kev ceev nruj heev, uas muaj peev xwm ua kom txuag tau hluav taws xob, txo cov nuj nqis, tiv thaiv lub chaw ua haujlwm ntev.

2, muaj zog corrosion ua hauj, kev kho sab tsuas ceev, qhov kev pab lub neej yuav muaj li 30-50 xyoo.

3, nrog rau txoj hauj lwm tsis zoo los ntawm kev deterioration thiab cov nyhuv, tsis haum dej, PE (tsawg dua 0,01%) thaum tsis sov.

4, siab zog epoxy, PE absorbent thiab kub yaj nplaum nplaum nplaum, thiab lwm yam., Muaj muaj siab corrosion reliability
