Isimo esingaphezulu sepayipi lensimbi saziwa ngokuthi indawo ezungezile ukuthi lokhu kungenxa yokugqunywa kwepayipi lensimbi elizungezwe inhlabathi, isimo sephayiphi ebusweni sihlukile emavikini amane enhlabathi.Ngakho-ke ungqimba lwamapayipi olulwa nokugqwala luyisithiyo esibalulekile sokuvimbela ukuguguleka komhlabathi.Isazi esaziwayo sangaphandle sabeka phambili "i-3PE france protective layer", kuze kube manje, izindlela zokulwa nokugqwala zisetshenziswa kabanzi.

Imisebenzi eyisisekelo ye-erw pipe coating:

1, okwenza ubuso beERW amapayipi ensimbi ngaphandle kokugqwala kwe-electrochemical of the earth medium, i-physics eyisisekelo yokuvikela ukugqwala kwebhaktheriya.

2, ukumelana nokunyakaza kwengcindezi ephakathi kwenhlabathi, ingcindezi emile kanye nendlela yamandla abrasion kanye nesakhiwo sokuvikela imishini eyisisekelo.

Izimiso eziyisisekelo zokukhethwa kwamapayipi egesi asemadolobheni:

a, izakhiwo ezinhle zokuvikela kanye nemishini;

b, ukumelana kahle nokusebenza kwe-cathodic disbondment;

c, ukumelana kahle namanzi, ukungena kwegesi;

d, ukusebenza kahle kokucwiliswa kwamakhemikhali ukumelana nezakhiwo zokulwa nokuguga;

e, ukumelana nokushisa okuphansi nokusebenza kokushisa okuphezulu;

f, ukulungisa nokulungisa kalula;

g, ngamanani afanelekile.
