Aluminosilicate fiber rope in pipe insulation work
Rope fills the gaps that rigid insulation cannot: expansion joints, penetrations and irregular cavities on hot equipment and pipework.
Aluminosilicate fiber rope, also called ceramic fiber rope, is used in power, heat supply and chemical plant for insulation and for sealing cavities on high-temperature equipment and pipework. It is made from aluminosilicate fiber, works up to about 1000 C continuously, and has low thermal conductivity and good thermal stability. Product performance follows GB/T 16400.
The installation standards that sit around it are GB/T 4272 for general technique, GB/T 8175 for design, GB 50126 for construction and GB 50185 for acceptance, with DL/T 5210.2 covering power construction quality.
Where rope earns its place
Rope is a packing material, not a substitute for a blanket. It goes into expansion joints, around penetrations, behind refractory linings and into irregular cavities where a board or blanket cannot be cut to fit. Compression recovery decides whether it keeps sealing after the joint moves.
