Insulated steel pipe ni gaw, pipeline htaw sa ai atsam ni hpe, n-gun rawng ai n-gun rawng ai hpaji masa ni hte kayau kaya galaw ai, n-gun rawng ai pipe system ni rai nga ai. Dai ni hpe wan sau, tsi mawan, ginwang hka ja ai, hka n-gun shayawm ai, bungli galaw ai shara ni hta n-gun shayawm ai bungli ni hta grai lang ma ai. Shanhte a madung manu gaw shanhte a laklai ai hkrang masa hta nga ai, dai gaw nbung katsi ai lam hpe shayawm kau ya ai sha n-ga, n-gun n-gun hpe ninghkap lu ai atsam hte n-gun n-gun hpe ninghkap lu ai zawn re ai engineering ra kadawn ai lam ni hpe hkan sa lu ai.
I. Insulated Steel Pipes ni a madung hkrang shapraw ai lam ni
Insulated steel pipe ni hpe langai sha re ai arung arai langai kaw na n galaw ai sha, bungli galaw ai n-gang pipe, insulation layer, makawp maga ai shinggan n-gup magap langai mi hte hpaw da ai. Nkau design ni hta, leak alarm line zawn re ai karum shingtau ai lam ni hpe mung bang da ai.
1. Magam bungli galaw ai ladat (inner Pipe)
Bungli galaw ai n-gang pipe ni gaw, htaw sa ai hka n-gun (hka n-gun, hka n-gun, shing nrai sau zawn re ai) hpe hkrak sha htaw ai rai nga ai. Dai ni gaw, n-gun n rawng ai n-gang pipe, spiral weld galaw ai pipe, shing nrai, dingyang n-gun n rawng ai shingnip ni hte galaw da ai. Dai arung arai hpe, carbon n-gang, n-gup n-gu n rawng ai n-gang, shing nrai, alloy steel zawn re ai, n-gun n-gun a arawn alai ni hpe madung tawn nna lata la ai. Dai kata na bunghku gaw, n-gun n rawng ai hte tsaw ai- pressure hpe ninghkap lu ai atsam ni hpe hkan sa ra ai, shinggan bunghku hpe insulation layer hte ngang ngang jum da ra ai.
2. Insulation Layer (kalang lang Insulation Layer)
Insulation layer gaw insulated steel pipe a core technical layer rai nga ai, shi a madung bungli gaw katsi ai hpe pat shingdang na matu re. Masha law law lang ai insulation arung arai ni hta:
Polyurethane foam (PUF): thermal n-gun n law ai (0.024 W/m·K), pat da ai n-gun kaba ai-cell n-gun, n-gun kaba ai n-gun atsam ni. Ya aten hta grau nna n-gun rawng ai insulation arung arai rai nna, bungli galaw ai shara ni hta n-gun n-gun n-gun (sh) shawng nnan e nga ai.
Rock wool/glass wool: Tsaw ai wa a- aten ladaw a matu hkan sa mai ai (ga shadawn, 500℃jan ), raitim, n-gun ja ai hte n-gun ja ai hygroscopicity nga ai.
Airgel composite layer: ultra- nhtoi grai n law ai thermal conductivity (<0.018 W/m·K), but it is more expensive and is primarily used in specialized, high-end projects.
Insulation layer a galu kaba ai lam hpe, nbung katsi ai lam, grup yin nbung n bung ai lam, sut masa lam ni hpe madung tawn nna, 30 kaw nna 150 mm du hkra rai nga ai.
3. Makawp maga ai Shell (Outer Sheath)
Makawp maga ai shell gaw, jak hte hkra machyi ai, UV radiation, ga nhpu ni hpe hkra machyi shangun ai kaw na insulation layer hpe makawp maga ya ai. Masha law malawng lang ai arung arai ni hta:
High{0}endsity polyethylene (HDPE): N-gun n rawng ai hte hka n shang lu ai, ga kata kaw jung na matu htuk manu ai, katsi ai-melt welding hte hpaw da ai.
Galvanized steel/aluminum: Ntsa kaw na pipeline ni (sh) tsaw ai{0}} n-gun kaba ai makau grup yin ni a matu lang ai, dai gaw jak rung n-gun kaba hpe jaw ya nna, shi a magam bungli prat hpe galu kaba wa hkra, anti{1}}}corrosion coating hte kayau kaya galaw mai ai.
Fiberglass hpe n-gun jaw ai plastic (FRP): Nbung laru hpe n-gun n law ai atsam hte 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-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-rawng ai shara ni a matu htuk manu ai.
II. Auxiliary hkrang hte bungli galaw ai lam ni
Nkau mi gaw tsaw ai{0}}end insulated steel pipe system ni gaw lawu na hkrang ni hpe grau nna shinggyin la lu na re:
Leakage alarm wire: Insulation layer hta bang da ai, dai gaw bungli galaw ai steel pipe hta hka lim ai lam byin wa ai shaloi, wan n-gun signal galai shai ai lam hku nna fault point hpe lawan ai hku mu lu ai majaw, shim lum lam hpe grau jat wa shangun ai.
Sliding bracket/support ring: thermal jat galu kaba wa ai myit ru myit tsang lam a majaw byin pru wa ai structural hkra machyi ai lam ni hpe shayawm na matu, galu kaba ai-} kaw na pru wa ai pipeline ni a matu jai lang ai.
Vacuum insulation (lawan and specialized design): Ndai gaw vacuuming hku nna katsi ai hpe grau shayawm ya ai, raitim hpaji masa manu gaw grai law ai.
III. Insulated Steel Pipe ni a hkrang shapraw ai lam ni
Hpa majaw nga yang, n-gun ja ai n-gun hpe n-gun jaw ai lam: Multi{1}}layer structure gaw, shinggyim hkum hkrang hku nna bungli galaw ai majaw, nbung n-gun n-gun yawm wa ai majaw, htunghking pipe ni hta na 1/5 kaw nna 1/10 du hkra katsi ai hpe shayawm ya lu ai.
Long Life: Shinggan na sheath gaw n-gun n rawng ai- gaw, 30 ning kaw nna 50 ning lapran na hkrang shapraw ai asak hkrung lam hpe hkam sharang lu ai.
Loi ai hku gawgap ai lam: Prefabricated direct{0}}}buried insulated pipe ni gaw, madang masat da ai factory galaw shapraw lu ai,- kaw sha nga ai interface hkyen lajang ai hta sha ra ai, gawgap ai aten hpe grai kadun hkra galaw ya ai.
Hkringmang daju gaw, grup yin makawp maga ai lam hte n-gun atsam hpe hkye la ai lam: N-gun n-gun hpe shayawm ya ai, "dual carbon" yaw shada lam ni a npu e, green industrial ra kadawn ai lam ni hpe hkan sa ai.
Daw dan lam
Insulated steel pipe ni a structural design gaw, arung arai hpaji, thermodynamics, hte engineering application ni hpe sung sung shinggyin la lu ai. Kata na bungli galaw ai n-gang pipe kaw nna shinggan makawp maga ai lam ni du hkra, layer langai hte langai gaw shi a bungli a matu grau kaja hkra galaw ya ai, hpang jahtum e "htuk manu ai htawt sit ai lam +{2}} aten galu ai lam + kam mai ai makawp maga lam" ngu ai yaw shada lam law law hpe lu la na matu yaw shada ai lam law law hpe lu la na re. Insulation arung arai nnan ni hpe gyin shalat ai hte (aerogel hte nano{5}inlation coatings zawn re ai), insulated steel pipe ni a hkrang gaw matut nna grau n-gun n rawng ai hte grau hpaji chye wa na re, n-gun nnan hte sung htum ai{6}}}}}}}} ai shara ni zawn re ai rawt jat wa nga ai ginra ni hta shanhte a jai lang mai ai atsam hpe jat wa na re.
