Anti-}corrosion Steel Pipe hpe jai lang na matu sadi maja ai lam ni hpe hkum tsup ai hku sawk sagawn ai lam
Dai majaw, n-gun ja ai n-gun hpe ninghkap lu ai atsam grai kaja ai majaw, anti-corrosion steel pipe hpe wan sau, tsi mawan, shingra wan, hka jaw ai bungli ni hta grai lang ma ai. Raitim, jai lang ai shaloi ahkyak ai sadi maja lam ni hpe n yu lanu lahku ai gaw, anti-corrosion coating hpe n lu galaw ai, pipe a asak hpe kadun shangun ai hte shimlam hte seng ai hkala nba ni hpe pyi byin shangun chye ai. Lahta na lam ni gaw, anti-corrosion steel pipe hpe jai lang na matu sadi maja ai lam ni hpe, lam mali kaw na, lam mali kaw na jai lang na matu sadi maja ra ai.
I. Hkamja lam: Hkum hkrang n hkru n kaja ai lam hpe koi gam na
Anti{0}}corrosion coating a anti-corrosion steel pipe (3PE, epoxy powder, etc.) hpe htaw sa ai shaloi loi loi hte hkra machyi shangun ai. Dai majaw chyeju hte sadi u:
Htap htuk ai lam: N-gang pipe hpe ngang ngang jum tek da na matu hte n-gun ja ai arung arai ni hte hkrak matut mahkai ai lam hpe koi lu na matu, ap nawng ai madi shadaw ai lam ni (sh) soft cushioning hpe lang u. Coating hpe n-gun n rawng hkra, gyit da ai shaloi pyi, n-gun dat bang u.
Hka hte hka lim ai hpe makawp maga ai: htawt sit ai shaloi hka n shang ai tarpaulin hte ka-up u, grau nna epoxy-corrosion coatings ni a matu, hka hte matut mahkai ai lam gaw shanhte a n-gun hpe shayawm ya lu ai.
Lift hte shara hte rau shara: Lifting galaw ai shaloi ap nawng ai sling ni hpe lang nna, wire sumri hte pipe lapran hkrak matut mahkai ai lam hpe koi gam u. Lifting point ni gaw, coating hta welds (sh) n-gun kya ai shara ni hpe koi ra ai.
II. Installation galaw ai lam: Damage hpe shayawm kau ai
Installation gaw anti{1}}}corrosion hpe hkra machyi shangun na matu tsaw ai{0}}risk stage re. Lahta na lam ni hpe laksan myit maju jung u:
Pipe End Protection: N-gun n-jaw shi yang, n-gun n-jaw shi yang, wan hkru ai wan n-gun n-htum hkra, pipe htum ni hta anti{0}}corrosion coating hpe pat da u.
Welding Ra ai lam ni:{-}site welding hta ra ai rai yang, weld seam hte n-gun shayawm ai n-gun lapran 10-15cm gap hpe tawn da na. Welding ngut ai hpang coating hpe bai bang dat u. 85% jan marang htu ai, hka lim ai, hka lim ai shara ni hta bungli galaw ai hpe pat hkum da ai.
Lata hte galaw ai lam ni: Lata n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-rawng hkra, lata hte galaw ai. Mechanical handling galaw ai shaloi, pipe a n-gun n-gun hte n-gun n-rawng hkra roller spacing hpe gram lajang u.
III. Operation Phase: Hkringmang hte makawp maga ai lam hpe hkang ai
Anti-corrosion steel pipe a galu kaba ai lam gaw, bungli galaw ai makau grup yin hte grai ni htep ai hku matut mahkai nga ai:
Media hta htuk manu ai lam: Hkau hkai ai lam (ga shadawn, acidic hte alkaline ntsin ni, tsaw ai- n-gun) gaw anti-}corrosion coating amyu hte bung ai hpe kam hpa ai. Ga shadawn, epoxy powder gaw acid- hpe n-gun ja ai raitim, n-gun ja ai hka n-gun ni hpe n hkam sharang lu ai.
Hkringhtawng hte Pressure n law ai: Design parameters ni hpe ngang ngang jum da ai. Grai katsi ai majaw, n-gun yawm mat nna, hkrat sum mat chye ai, n-gun kaba ai majaw, myit ru myit tsang lam ni hpe loi loi hte n-gun yawm shangun chye ai. Cathodic Protection Coordination: Wan wut ai pipeline ni gaw, n-gun n rawng ai n-gun n rawng ai shara ni hta wan n-gun makawp maga lam hpe hkam la lu na matu, cathodic makawp maga ai atsam hpe ayan chyam dinglik ra ai (galaw majaw-05V kaw nna -1.2V) hpe n-gun n rawng ai shara ni hta wan n-gun makawp maga ai lam hpe hkam la lu na matu re.
IV. Hkamja lam hte jep joi ai lam: N kaja ai hku gram lajang ai lam
Aten tup gram lajang ai lam gaw, anti-corrosion steel pipe ni a asak hpe kalang lang jat ya lu ai:
Hkrang shapraw ai lam hpe jep sagawn ai lam: Bubbling, n-gun n rawng ai, shing nrai, n law htum shaning shagu n-gun n rawng ai, n-gun n rawng ai shara ni hpe madung tawn nna, n-gun n rawng ai shara ni hpe madung tawn nna jep yu u.
Electro-spark chyam dinglik ai lam: Hka lim ai pipeline ni hpe 2-33 ning shagu electro{1}}spark tester lang nna, coating kata na pinholes ni a matu jep joi ra na re. Leak ni hpe n-gun n rawng ai nsam (sh) katsi ai shrink tape hte gram lajang ra ai.
Hkringmang daju a shingra tara hpe jasan jaseng ai lam: Pipeline grup yin hta nli tum ni hte n-gun n rawng ai nhprang dat ni hpe shaw kau na matu (MIC).
Daw dan lam
Anti{0}}}corrosion steel pipe ni a bungli galaw ai lam hta akyu nga ai gaw, hkum tsup ai hte madang masat da ai hparan hpareng ai lam hta madung nga ai. Lahta na sadi maja ai lam ni hpe n-gun ja ai hku hkan sa ai lam gaw, mawdaw lam kaw nna kabai kau ai du hkra, anti{2}}corrosion effect hpring tup hpe madi shadaw ya nna, dai masa hpe shim lum ai hte ngang grin ai hku galaw lu na matu mung rai nga ai. Laksan bungli masa ni a matu (deep sea hte n-gun ja ai acid makau grup yin zawn re ai ni a matu) gaw, galaw shapraw ai wa hpe laksan hparan ladat ni hpe san yu nna, myi nmu ai sha bungli n galaw na matu hpaji jaw da ai.
