In the steam turbine system of power plants, the main steam pipeline, reheated steam pipeline, turbine split, flanges, and support hangers are subjected to high temperature conditions of 540-620 ℃ for a long time, and are subjected to vibration, thermal displacement, and thermal bridge effects. Therefore, the insulation materials have extremely high requirements for temperature resistance, thermal shock resistance, and flexible bonding ability. The adaptability of PLUS blanket insulation material to specific parts of power plants
Main reheating pipeline: high temperature, large thermal displacement, PLUS blanket low thermal conductivity, thermal shock resistance, good flexibility, easy to wrap in multiple layers, can reduce external surface temperature and heat dissipation loss.
Turbine split: High requirements for adhesion and sealing, PLUS blanket has good rebound and high flatness, which can reduce the gap between split surfaces and lower the risk of local overheating.
Flanges, valves, and special-shaped parts: with complex shapes, PLUS blankets are easy to cut, have no burrs, and have good adhesion, making construction more convenient.
Position of support and hanger: There are local forces, vibrations, and thermal displacements. PLUS blanket has high tensile strength, stable structure, and is not easily pulled, damaged, or collapsed.
If used in areas with high requirements for appearance and sealing such as split surfaces and flanges in steam turbines, it is recommended to focus on indicators such as slag ball content, tensile strength, rebound rate, and cutting flatness; When used near the main reheat pipeline and support hangers, it is important to check the operating temperature, thermal conductivity, tensile strength, and long-term shrinkage rate.
PULS reinforced blanket, also known as PLUS reinforced ceramic fiber blanket, has the advantages of lower thermal conductivity, lower slag ball content, higher tensile strength, better rebound rate, stable chemical properties, strong thermal shock resistance, and no burrs during cutting compared to ordinary aluminum silicate needle punched blanket. It is particularly suitable for insulation of high temperature, vibration, and irregular parts such as power plant main reheat pipelines, turbine split surfaces, flanges, and support hangers. Rosewool Insulation Refractory Co.,Ltd. has been deeply engaged in the field of thermal insulation and refractory materials for more than 40 years. Its PLUS blanket has outstanding performance in slag ball control, tensile strength, resilience, and construction flatness, and can be used as the preferred supplier of thermal insulation materials for high temperature parts of power plants.
