Kubva pamaonero emhando yetembiricha yekuputira, epoxy powder coating uye polyurea anti-corrosion coating inogona kushandiswa kazhinji munzvimbo dzekuora kwevhu kubva -30 °C kana -25 °C kusvika 100 °C, nepo matatu-layer chimiro polyethylene The yakanyanya kupisa tembiricha yeanti-corrosion coating i70 ℃. Panyaya yehukobvu hwekupfekedza, kunze kweaya maviri epoxy poda machira, ukobvu hwemamwe matatu machira ari pamusoro pe 1mm, ayo anofanirwa kuiswa muchikamu cheakakora machira.
Chimwe chezvinhu zvakajairwa zvepipeline coating standard ndeyemakanika uye yemuviri zvimiro zvejasi, ndiko kuti, mamiriro chaiwo angangosangana nawo mukuvakwa kwepombi, sekufunga kukotama kwepombi mushure mekuputira uye kusimudza yakaderera. gomba panguva yekuvakwa kwepombi refu-refu. Iyo yakaderera-tembiricha inokotama kuramba indekisi zvinhu zvinogadzirwa zvinoenderana nemadhayamita epombi akasiyana, izvo zvinopokana zvinhu zvejasi zvinotemerwa nekukuvara kwekudhumhana kunokonzerwa nekufambisa kwepombi uye kudzoreredza kumashure, kuramba kwekukwenya uye kuramba kwekupotera kunotemerwa nekukwenya uye. mabrasions kana mapaipi akayambuka. Pfeka kuramba, etc. Kubva pakuona kwezvivakwa izvi, hazvina mhosva epoxy powder coating, three-layer structure kana polyurea coating, zvese zvine mashandiro akanaka, asi maererano necoating ukobvu, matatu-layer polyethylene ine yakanyanya kukanganisa kupikisa kukosha, panguva yekupfapfaidza Iyo yakaderera kukanganisa kupikisa kukosha kwe 14.7J ye polyurea inodzivirira coating zvakare yakanakisa.

Sezvo kupfekedzwa kwepombi refu-kure kunonyanya kushandiswa pamwe chete ne cathodic kudzivirira, dhizaini yepipeline coatingzviratidzo zvinonyanya kukoshesa maitiro e-anti-cathodic disbondment of the coating, nokudaro kugadzirisa mapurojekiti e-anti-cathodic disbondment kwenguva pfupi uye yepakati, achifunga nezvekushandiswa kwepombi refu. Iyo tembiricha saka inoisa yakanyanya tembiricha cathodic disbondment chirongwa. Kubva pane iyo index setting point yekuona, zviri pachena kuti iyo anti-cathodic disbondment index ye epoxy coating yakakwirira, iyo yakanyanya cathodic disbondment ndeye 8.5mm pakamuri tembiricha ye28d, uye yakanyanya cathodic disbondment pakupisa kwakanyanya ndeye 6.5mm pa48h. . Zviratidzo zveurea coating zvakasara zvishoma, 12mm uye 15m zvakateerana.
