Thanks Guest. Please register and identify yourself so that I know who i am thanking for this important software which, today i have because of you . Now I can do away with my guess work & practical experience.

Thanks, but I must politely decline registering, I am not sure if you have followed previous threads with my "mystery" answers - but I prefer to remain anonymous.

But, I will leave you my signature smiley

Smiley - You are getting interesting and I like your style to remain anonymous. Your mystery answer threads did pass by but I did not take notice. Now I have a fair feeling of your writing & intellectual style and will recgonise you even if you do not sign as smiley.

Yup - you are onto me, darn ..................... I am going to have to make a conscious effort to change my writing style.

Take an infra red temperature & measure temperature. anywhere between 38c to 42c is a 95% good insulation. Better - just put your palm and if you can stand comfortably, that's a 90% good insulation.

Personal experience: Steam mains upto 15 bar 1/2" to 3" -2" insulation thickness, 32 kg/m3 density & 4" to 12" mains - 4" insulation thickness, 64 kg/m3 density if fibre glass wool blanket 240c.

Now since mostly rockwool with minimum 80 kg/m3 - 2" thickness till 3" main & 4" on 4" main & +.

Thermo oil lines 250c - minimum 100 kg/m3 density 550c.

Above only based on my practical experience. Serves my purpose.

Checkup spec sheets of insulation material & type preferable to you, apply as per desired thickness, density & temperature.Also depends what is locally available.

Another program I just found is located at:

NOTE: I have not downloaded nor tried this program so I can't really vouch for it.

Thanks smiley! I've bookmarked this. I'll buy some of their softwares when I visit USA for they are not that expensive.
