What is the insulation effect of aluminum silicate needle punched blanket in the petroleum industry

These are two of our recent customers, one from Japan and one from Canada. They both gave good feedback about our delivery and goods quality.

"400 adiabatic board made of xonotlite, a high-temperature resistant composite board with high density", "Xonotlite" typically refers to high-density, high-strength calcium silicate insulation products, with xonotlite as its main crystalline phase. High-density xonotlite itself is characterized by high density, which brings better compressive strength and dimensional stability, but with a slightly higher thermal conductivity. Its density is usually between 200–300 kg/m³ or even higher (compared to about 150–220 kg/m³ for ordinary calcium silicate boards).

How to construct and apply rock wool roll felt with wire mesh as insulation material for power plants? In the insulation engineering of pipelines and equipment in power plants, there is a standard process for the construction of rock wool roll felt with wire mesh (also known as steel wire mesh rock wool joint felt). Its biggest feature is that the outer wire mesh is like a "steel skeleton", which can tightly wrap around the internal rock wool, especially suitable for parts with high vibration and high requirements for the integrity of the insulation layer such as power plant boilers and large-diameter hot air pipelines.
