Anti-corrosion steel pipe hman dan tur chiang taka thlirletna kimchang
Corrosion resistance tha tak a neih avangin anti-corrosion steel pipe hi petroleum, chemical, natural gas, leh tui supply industry-ah te hman a ni nasa hle. Mahse, hman chhunga fimkhur lohna pawimawh tak takte chuan anti-corrosion coating a tichhia thei a, pipe dam rei zawng a ti tawi thei a, himna accident pawh a thlen thei a ni. A hnuaia tarlan te hian anti-corrosion steel pipe hman dan tur chu aspect pali atanga hman dan tur a tarlang chiang hle a, chungte chu: Transportation, Installation, Operation, leh Maintenance te an ni.
I. Transportation: Taksa lama chhiatna thleng lo .
Anti-corrosion coating anti-corrosion steel pipe (3PE, epoxy powder, etc. ang chi) te hi an phurh chhuah laiin an inhnaih tawn a, an inhnawh tawn a, an compression hmangin awlsam takin an tichhia thei a ni. Chuvangin, heti hian hre reng ang che:
Loading dik tak: Steel pipe humhim nan dedicated support emaw soft cushioning emaw hmang la, thil harsa tak tak nena direct-a inhnaih loh tur a ni. Coating strangle a nih loh nan khian khirh hunah pawh force la.
Ruah leh tui laka invenna: Transportation laiin waterproof tarpaulin hmangin khuh la, a bik takin epoxy-based anti-corrosion coatings te tan chuan tui nena inhnaih hian an adhesion a tihtlem theih avangin.
Lift leh place with care: Lifting laiin dedicated slings hmang la, wire rope leh pipe inkarah direct contact loh tur a ni. Lifting point-ah chuan coating chhunga weld emaw weak spot emaw a awm loh tur a ni.
II a ni. Installation kalpui dan: Damage tih tlem .
Installation hi -risk stage a ni a, anti-corrosion coating a chhiat theihna tur a ni. A hnuaia thu chiang zawkte hi a bik takin ngaihven rawh:
Pipe End Protection: Cutting emaw welding emaw hmain pipe tawp lama anti-corrosion coating chu tape emaw plastic cap emaw hmangin seal la, chu chuan kangmei a chhuah loh nan.
Welding Requirements: On-site welding a ngai a nih chuan weld seam leh anti-corrosion coating inkarah 10-15cm gap dah la. Welding zawhah coating chu reapply leh rawh. Ruah sur, vur, emaw boruak lum 85% aia tam awmna hmuna hnathawh chu khap tlat a ni.
Handling instructions: Kut chhuak atanga corrosion awm loh nan kutkawr bun laiin kutkawr bun thin ang che. Mechanical handling lai hian pipe bending leh deformation awm loh nan roller spacing chu siamrem tur a ni.
iii a ni. Operation Phase: Environment leh Pressure control dan .
Anti-corrosion steel pipe-a hun rei tak chhunga a thawh dan hi a hnathawh dan nen a inzawm tlat a ni:
Media compatibility: Conveying medium (eg, acidic leh alkaline fluids, high-temperature steam) chu anti-corrosion coating type nen a inmil tih nemnghet rawh. Entirnan, epoxy powder chu acid-resistant mahse solvent chak tak lakah chuan a do thei lo.
Temperature leh pressure limits: Design parameters te chu khauh takin zawm rawh. Temperature tam lutuk chuan a coating chu a ti nem thei a, a tla thei bawk a, pressure sang tak chuan awlsam takin stress cracking a thlen thei bawk. Cathodic Protection Coordination: Pipeline phum tur chuan anti-corrosion coating-a chhiat tawhna hmuna electrochemical protection awm theihna turin cathodic protection potential (a tlangpuiin -0.85V to -1.2V) test reng a ngai a ni.
iv. Enkawlna leh enfiahna: A chhiatna chu rang taka siamthat .
Regular maintenance hian anti-corrosion steel pipe te dam chhung hi vawi tam tak a ti rei thei a:
A lan dan enfiahna: Coating chu kum tin a tlem berah bubbling, cracking, emaw peeling emaw a awm leh awm loh mitin enfiah la, weld leh elbows ang chi stress concentration area-te chu ngaihtuah rawh.
Electro-spark testing: Pipeline phumte chu kum 2-spark tester hmangin kum 2{{1}spark hmangin coating-ah pinhole awm leh awm loh enfiah thin tur a ni. Leak hi anti-corrosion paint emaw heat shrink tape emaw hmanga siamthat tur a ni.
Environment tihfai: Microbiologically influenced corrosion (MIC) venna atan pipeline vel a buh leh buhfai leh corrosive deposit (saline-alkali soil ang chi) te chu paih chhuak rawh.
Tawpna
Anti-corrosion steel pipe te performance advantage chu comprehensive leh standardized management ah a innghat a ni. Stage tina a chunga fimkhurna khauh tak zawm tlat, lirthei atanga paih chhuah thlengin, anti-corrosion effect kimchang leh system him leh nghet taka kalpui a nih theih nan a enkawl a ni. Special working conditions (deep sea leh strong acid environment ang chi) tan chuan a siamtu hnenah customized solutions siam a, mitdel anga thawk lo turin a tha.
