Insulating materials for steam pipes

[boybi]

meron ba kayong alam na supplier na mura lang magbenta? and baka meron kayong alam na mga alternative material na mas economical, yung kadalasan kasing ginagamit yung parang styrofoam na makapal. baka meron ibang klaseng material na mas mura pero ok naman ang insulating property.

[yebo]

may mga factors na dapat i-consider dyan pards...

temperature of steam - decides what type of insulation to use
allowable heat loss (temp at supply point - temp at point of use) and length of piping - decides the thickness of your insulation.
vibration - baka need ng cladding yung insulation pag sobra vibration

kliyente namin gamit fiberglass insulation sa kanilang mga steam pipes covered wiht GI cladding. di ko alam na pwede styrofoam sa steam. we use polyurethane sa malalamig na linya of course with metal cladding(usually SS). sabi nga yebo depende sa design na gusto mo maachieve.

ang problema, hindi namin namemeasure yung temp. basta makapagdeliver ng steam at the end of the pipe pwede na. meron din heat exchanger for drying, pero bihira ito gamitin.

niwde11, hindi pwde styro, matutunaw agad. yung appearance lang ang mukhang styro.

what about ung material na silver on one side and parang styrofoam material on the other? ung tipong ginagamit sa roof ng warehouses e.g. ung sa PCX Shaw....

pang bubong lang talaga yun. matutunaw agad yung styro sa init ng steam pipes (more than 100 degrees C )

I think standard na ang fiberglass insulation pag high temp...

yung dito sa 'min, ayon sa ming design engineer, styrofoam pwede daw for 60°C and below. meron din yung tawag perlite or silicalite - para syang refractory material na porous - para syang pre-formed plaster of paris na nakakorte ng pang wrap sa steam pipes. for high temp applications fiberglass daw pero di raw advisable fiberglass kung exposed sa sunlight + rain yung pipes unless it is well clad and covered with aluminum sheets and sometimes, asphaltic material. corrosive daw fiberglass pag nabasa at nagco-collapse daw. so take your pick.

hth ;)

heard before vermiculite insulation? which contains asbestos that resists high temp..

[niwde11]

fiberglass talaga gamit sa steam kaso kailangan talaga sa indoor lang. kung open baka pwede suggest ni rsnald.
boybi, pm mo sakin kung kailangan mo pa. last price na tanong ko sa kanila is around P530 for a 1"dia pipe(forgot the thickness of the insulation and the length maybe standard 4 feet). pm ko sayo number kung interested ka.
