Tsanangudzo:

Sour services simbi pombi inoisirwa mapaipi munzvimbo inoora.

Izvo zvinokonzeresa kuvuza kwepombi yeoiri uye gasi, zvimwe zviitiko kunyange kuputika.Pipe corrosion ine njodzi huru kune kuchengetedzeka kwemunhu uye kusvibiswa kwezvakatipoteredza, saka kugadzirwa kwepombi yevhisi yakakosha kwakakosha.

Sour sevhisi pombi inonyanya kushandiswa munzvimbo yeH2S.Nepo H2S ikemikari inokuvadza iyo kazhinji iri nyore kugadzira iyo corrosion.

Kana kudzvinyirirwa kwechikamu cheH2S kunosvika 300 pa, mapaipi emutsara anoshandiswa achange aine anti-acid corrosion performance.Sour service pipe inosanganisira NACE pipe.

Maitiro ekusvira sevhisi pombi yakagadzirwa:

API Spec 5L, iyo pombi simbi inoshandiswa kune yakavava sevhisi pombi ndeyekuchena-yakaurayiwa simbi.

Izvo zvichacherechedzwa kuti, iyo yakakwirira kuchena kwesimbi inogona kuvimbisa yakaderera S, P uye kumwe kusvibiswa.

Chiyero chekutonga uye chekuongorora chekubatanidza chimiro chepipeline simbi yepombi yevhisi yevhisi inodiwa nekuti iyo hydrogen inokonzerwa nekuputika kunokonzerwa nekubatanidzwa kunotanga kutsanangurwa muchimiro chayo.

Chemical properties:

Izvo zviri mukati meC, P, S uye kabhoni yakaenzana mumakemikari ekuumbwa kwepombi yevhisi sevhisi yakaderera pane yakajairwa mutsara mapaipi, iine kunyatso kudzora zvinodiwa.

Kunyanya kune zvirimo S, chinhu chinokuvadza zvakanyanya munzvimbo dzekuora, saka kune inovava sevhisi pombi inofanirwa kudzora S yakakura 0.002.
