Second, adiabatic insulation properties Rock wool products have a small thermal conductivity, about 25 ° C under normal temperature conditions, thermal conductivity between 0.035 ~ 0.044W / (mk), light weight, non-toxic soft and easy to process. It is widely used in metallurgy and chemical construction.
Third, sound absorption performance:
Rockwool products have excellent sound insulation and sound absorbing properties. The sound absorbing mechanism is the porosity of the products, and the pores can penetrate each other and most of them are not sealed, thus forming a flow resistance. When the sound wave passes through this time, friction is generated due to the action of the flow resistance, and a part of the acoustic energy is changed into heat energy to be lost or absorbed by the fiber, which is widely used in auditoriums, shopping malls, theaters, subways, stations, airports, hotels, and high-end residences.
A Blind flange is round plate which has all of the relevant boltholes but no center hole, and because of this feature this flange is used to close off the ends of a piping systems and pressure vessel openings. It also permits easy access to the interior of a line or vessel once it has been sealed and must be reopened.
The blind flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. This blind flange is available in various sizes and materials and is used to provide positive closer on the ends of pipes, valves or equipment nozzles. This flange helps in easy access to a line once it has been sealed. The blind flange is sometimes custom made or machined to accept a nominal sized pipe to which reduction is being made.
