PVC pipe hpe hka hte hka lim ai, wan n-gun, hkai lu hkai sha ai, hkai lu hkai sha ai, hte kaga hkai sun ni hta grai lang ai majaw, n-gun n law ai, n-gun n law ai, manu n law ai, n-gun n law ai. Raitim, n kaja ai hku jung nna gram lajang ai lam gaw, hka lim ai lam, n-gun n rawng ai lam ni, system hkrat sum ai lam ni pyi byin chye ai. Ndai laika buk gaw PVC pipe hpe htum hkra, matut mahkai na matu, matut mahkai na, pat da ai, shani shagu gram lajang na matu, PVC pipe hpe atsawm sha, shim lum ai hku jai lang lu na matu, hkrak tup tsun dan na re.
I . PVC Pipe hpe galai shai ai ladat ni
PVC pipe hpe cut galaw ai gaw shawng nnan na lahkam rai nna, cut a quality gaw hpang na matut mahkai lam ni a n-gun hpe hkrak hkra hkra machyi shangun ai. Lahta na arung arai ni hte ladat ni hpe hpaji jaw da ai:
. Dai hpe htu ai shaloi, pipe axis hta n-gun n rawng hkra galaw nna, pipe a jahtum hpe n shinggrup na matu, loi loi hte maren sha shamu shamawt u. Dai hpang, hka htung (sh) sandpaper hpe lang nna, sealing arung arai ni hpe n hkra hkra, burr ni hpe shaw kau u.
. Dai ni hpe lang na matu loi ai, raitim, n-gun rawng ai cut surface hpe galaw u.
. Nbungli n-gun n-gun n-rawng hkra, shim lum ai myi man ni hpe bu hpun u.
Myit yu na lam: Cut ngut ai hpang, pipe jahtum ni hpe n-gun n rawng ai kun ngu yu u. N-gun n rawng ai (sh) oval deformations ni nga yang, flaring tool hte bai gram lajang (sh) gram lajang u.
II. PVC Pipe matut mahkai ladat ni
PVC pipe matut mahkai ladat ni hta madung hku nna hparan ladat matut mahkai ai lam, elastic sealing ring matut mahkai lam (socket-type, hte threaded matut mahkai lam ni lawm ai. Laksan lata ai lam gaw, masat da ai masa hpe madung tawn ra ai:
.
• Lahkam ni:
• Fitting hte pipe a matut mahkai ai lam ni hpe jasan jaseng u, dai hku nna sau hte nhpu n lawm hkra galaw u.
• Glue adhesion hpe grau kaja hkra galaw na matu, n-gun n rawng ai sandpaper hte matut mahkai ai shara hpe loi mi san seng hkra galaw u.
• Pipe hte htap htuk ai shara de (PVC- hte seng ai hka lim ai cement zawn re ai) hpe bang nna, kalang ta bang nna, shawng nnan hta shim lum ai aten du hkra, second 15-30 laman 1/4 turn hpe shinggrup da u.
• Hka (sh) n-gun hpe n bang shi yang, hkying hkum 24 tup tsap na matu ahkang jaw u.
• Key Points: Dai glue gaw PVC arung arai ni hte htap htuk ra ai (ga shadawn, CPVC pipe gaw laksan tsaw ai- aten ladaw glue ra ai). Grai law hkra jai lang ai gaw glue overflow byin shangun nna, hkrang hpe hkra machyi shangun na re.
.
• Lahkam ni:
• Hka htung kata de bang na matu sau htu ai hka (sau hka zawn re ai ni) hpe koi u.
• Pipe hpe fitting a socket hte shingdaw nna, masat da ai line (galaw majaw gaw fit a kata bunghku ntsa e tawn da ai ring langai mi).
• Dai shara hpe loi mi gram lajang nna, pat da ai ring hpe shara kaw tawn da na matu minit 5 daram dung shangun u.
• Akyu: Glue n ra ai, garan ginhka ai lam hte mai byin ai lam ni hpe gram lajang ai lam ni, ayan galai shai ra ai bungli masing ni a matu htuk manu ai.
3. Myit sawn sumru ai matut mahkai lam (Auxiliary Method)
Hpri n-gun hpe n-gun n-gun hte matut mahkai ai shaloi, threaded adapter hpe lang u. Shinggan na thread hpe PTFE tape hte shinggrup da nna, seal hpe grau kaja hkra galaw u.
III. Sealing hte Leak hpe makawp maga ai lam
Matut mahkai lam teng ai rai yang pyi, galu kaba ai- aten masat da ai hpe lu la na matu, jat nna galaw ra ai lam ni hpe naw galaw ra ai:
• Solvent- hta na n-gun n rawng ai majaw byin pru wa ai n-gun n rawng ai lam hpe koi lu na matu, n-gun n rawng ai ni (H&K (USA) hte ThreeBond (Japan) zawn re ai) hpe ra sharawng ai.
• Lahkawng ngu na sealing: Ahkyak ai n-gup magap ni a matu ( pump outlet zawn re ai), hka n shang ai tape hpe shinggrup da na (sh) adhesive cures ngut ai hpang silicone sealant hpe bang na.
• Pressure testing: Install galaw ngut ai hpang, hka hpe pipe hku nna hka dat nna, design value hta na htam 1.5 daram n-gun hpe loi loi hte jat bang u. Minit 30 daram yu nna, hka lim ai lam n nga ai hpe yu u. Pipe hpe hkap la mai ai ngu sawn la ai.
IV. Shani shagu na gram lajang ai lam hte PVC Pipes ni hpe gram lajang ai lam
1. Ma lajang ai lam ni
• External Damage hpe koi gam na: Hka lim ai pipe ni hpe backfill a n-gun rawng ai (30cm hta grau kaba ai (sh) dai hte maren sha re ai) hte shinggrup da ra ai. Exposed pipe ni hpe makawp maga ai palawng ni hte bang na matu hpaji jaw da ai.
• Anti{{0} +UV Aging: PVC pipe ni gaw shinggan de aten galu lang ai gaw UV- hpe ninghkap lu ai (sh) jan n-gun n-gun hte shinggrup nna, htum mat ai hte n-gun yawm mat ai hpe shayawm lu na matu rai ra ai.
• Temperature Limit: PVC pipe gaw madung hku nna 60℃hta n-gun n rawng ai nbung katsi ai hpe ninghkap lu ai. Tsaw ai- ai aten hta hka n-gun (hka n-gun zawn re ai) a matu CPVC pipe hpe lang ra ai (sh) insulation hpe bang ra ai.
2. Manghkang byin shangun ai manghkang ni
• Minor Cracks: Pipe a grup yin a 1/4 hta n-pu rai yang, PVC patching glue (sh) epoxy resin hpe lang nna aten kadun laman gram lajang mai ai. Grai hkra machyi ai lam gaw pipe daw ting hpe galai ra ai.
• Loose Joints: Sealing ring hpe shara htawt na matu jep yu nna, sau hpe bai bang nna, bang ai sung ai shara hpe gram lajang u.
• Blockages: N-gun n rawng hkra galaw na matu pipe hpe ayan shinggrup u. Blockage byin wa ai rai yang, pipe cleaner (sh) tsaw ai- pressure hka jet hpe lang nna jasan jaseng u.
PVC pipe hpe jung da ai hte gram lajang ai lam gaw, atsawm sha myit yu ra ai, hpa majaw nga yang, yawng mayawng gaw, hkrak ai lam kaw nna, matut mahkai ladat ni du hkra, system a asak hpe hkrak hkra hkra machyi shangun ai. Ndai ladat ni hpe sharin ya ai gaw, n-gun rawng ai lam hpe grau kaja hkra galaw ya ai sha n-ga, hka lim ai hte hka lim ai zawn re ai manghkang ni hpe mung atsawm sha pat shingdang ya lu na re. Grai sawng ai bungli masing ni a matu, hpaga lam a madang ni hpe hkan sa na matu, hpaji ninghkring langai hte bawngban na matu (sh) hpaji ninghkring langai hte bawngban na matu hpaji jaw da ai (GB/T 10002 (sh) ASTM D1785 zawn re ai). PVC pipe hpe hkrak jai lang ai gaw, manu jahpu a lahkawng lang akyu hkam sha lu ai-}}}ra lapran na akyu ni hpe grau law hkra jai lang lu ai.
