Steel spiral Pipe hpe

Double- maga de na hka kata de bang da ai Arc Welding spiral Steel Pipe
Double- maga de na Submedged Arc Welding Spiral Steel Pipe gaw n-gang n-gang kaw na galaw ai n-gang pipe langai mi re. Shi gaw spiral- hkrang shapraw ai jak langai mi hta hkrang shapraw nna, lahkawng lang-} maga de na hka kata de shang ai arc welding hpaji hpe lang nna matut manoi shinggrup da ai.

Pipe a matu Spiral Steel Pipe hpe
Spiral steel pipe a matu Piling pipe a matu, laksan hku nna SSAW (Spiral Submered Arc Welded) pipe hpe, n-gun atsam, n-gun n-gun, manu jahpu-}eeffectness a majaw, gap na matu, gap na matu, law malawng lang ma ai. Dai hpe steel strips ni spiral hku nna galaw shapraw ai majaw, diameter kaba ni hte hkrak hkra galaw lu ai.

Dredge Spiral Steel Pipe hpe
Dredge spiral steel pipe ngu ai gaw, hka lim ai bungli ni hta law malawng lang nna, hka lim ai nlung, nlung, hte nhprang arai ni hpe htaw sa na matu lang ai steel pipe ni hpe tsun mayu ai. Ndai pipe ni gaw shanhte a n-gun, ngang grin ai lam, n-gun n-gun hpe ninghkap lu ai atsam ni a majaw chye ai majaw, grai sawng ai panglai makau grup yin ni a matu htuk manu ai.

Diameter kaba ai Spiral welded Steel Pipe hpe
Large-}}diameter spiral pipe kaba ai gaw 1 metre hta grau kaba ai spiral steel pipe amyu langai mi re. Dai hpe hpaga lam hte npawt nhpang gawgap bungli amyu myu hta lang ma ai. Shi a arawn alai ni hta, hka lwi ai atsam kaba ai, n-gun kaba ai, n-gun n-gun n-gun, spiral weld structure ni lawm ai.

Core pipe:Hka htung hpe htaw sa na matu lang ai bungli galaw ai n-gang pipe langai. Core tube a arung arai ni a hkrang shapraw ai lam, shinggan diameter, dimensional hkam sharang ai lam, n law htum bunghku galu ai lam ni gaw, dai hte seng ai mungdan (sh) hpaga lam a madang ni hte maren rai nna, core tube a ntsa hpe kaga n san seng ai, sau, hka zawn re ai kaga n san seng ai arung arai ni kaw na shaw kau ai.

Makawp maga ai cushion:Core tube hpe n-gun n rawng hkra galaw ai majaw, core tube hte insulation layer lapran na interlayer hpe makawp maga na matu. Core pipe gaw spiral welded steel pipe hpe hkap la nna, inorganic insulation layer hpe n-gun ja ai arung arai ni hte galaw da ai shaloi, makawp maga ai cushion hpe jaw ya ai. Ndai makawp maga ai cushion layer hpe aluminum silicate felt hte madung hku nna galaw da ai, 192kg/m3 hta grau nna n-gun n-gun (sh) dai hte maren sha rai nga ai, nta kata na nbung katsi ai shara hta 0.056w/(m·k) hta grau nna n-gun n-gun (thermal conductivity), 4% hta grau ai (sh) dai hte maren sha n-gun rawng ai wire ni a n-gun yawm ai lam hpe shayawm ya ai.

Organic insulation layer:Organic insulation arung arai ni hte galaw da ai insulation layer. Dai gaw, n-gun ja ai polyurethan foam, density 55-65kg/m3, compressive n-gun 0.2MPa hta grau kaba ai (sh) maren sha rai nga ai, thermal conductivity 0.027w/(mji) hta grau ai (sh) maren sha rai nga ai, hka hkap la ai hta n-gun n law ai (sh) 3% hta n-gun n law ai, 140℃hta jai lang mai ai nbung katsi ai lam n law ai (sh) dai hte maren sha rai nga ai.

Inorganic insulation layer:Insulation layer hpe nbung katsi ai hpe n-gun ja ai inorganic insulation arung arai ni hte galaw da ai. Nta kata na nbung katsi ai shara hta thermal conductivity gaw 0.055w (m•k) hta grau ai (sh) maren sha re.

Shinggan makawp maga ai hka htung:Insulation layer hpe ga kata na hka n-gun yawm mat ai kaw na makawp maga ya ai shinggan makawp maga ai layer gaw, core tube hpe madi shadaw ya nna, n-gun langai ngai hpe hkam sharang lu ai.
