Polyurethane foaming technology is often used for insulation of low-temperature pipelines below 100℃, and then wrapped with two cloths and three oils. The advantage is that the construction is fast and suitable for mass production. The disadvantage is that the insulation quality is uneven and leakage accidents are easy to occur at the interfaces.
Rock wool was first used as the insulation material for high-temperature pipelines below 600℃. Rock wool is generally used as the hot surface insulation material, and then wrapped with two cloths and three oils. The advantage is that the cost of pipeline insulation is low, but the insulation effect Not very ideal;
Large heating companies generally use finished aluminum silicate insulation pipe shells. For thicker insulation, a multi-layer insulation structure of large aluminum silicate pipe shells within small pipe shells can be used. The advantage is that the construction is fast; the disadvantage is that it only has standard specifications, and generally aluminum silicate tube and shell manufacturers produce large quantities of customized products; another major disadvantage is the transportation damage rate and increased costs. Fire Dragon Energy Saving
Experience and application: Overhead pipes are generally insulated with ceramic fiber blankets or removable insulation sleeves. The advantage is that it is suitable for high-temperature pipe insulation of any size.
The advantages and disadvantages of the two applications:
(1) Overhead pipes are generally insulated with fire dragon ceramic fiber blankets.
Advantages (1) It can not only achieve the thermal insulation effect; Advantage (2) It can also meet the fire protection level A1 required for fire protection; Advantage (3) The price is reasonable and relatively low.
Disadvantages: During maintenance or when the life of the metal pipe expires, the fire dragon ceramic fiber blanket insulation layer needs to be replaced after being removed, which can be said to be a one-time use.
(2). At present, the insulation of overhead pipelines is constantly being upgraded, and detachable ones such as detachable insulation sleeves are becoming more and more widely used.
Advantages (1) It is produced at the manufacturer first and then directly packaged for construction. The construction is simple and fast, saving time and the installation cycle is short. Advantages (2) More importantly, it is detachable, reusable, energy-saving, environmentally friendly, and has a long service life.
Disadvantages: The one-time investment cost is relatively high, but the energy saving can recover the cost within a few years. Fire dragon saves energy.
