Recently, a batch of customized calcium silicate pipes and shells was packed and shipped from the Rosewool Insulation Refractory Co.,Ltd. , destined for a high-temperature pipeline insulation project at an aluminum plant. Designed for the complex and demanding high-temperature conditions in electrolysis and melting workshops, this rigid calcium silicate pipe and shell has become the mainstream choice for high-temperature pipeline insulation in the aluminum industry, thanks to its stable thermal insulation performance and high-strength, durable product characteristics.
Calcium silicate pipe shells are asbestos-free Class A1 non-combustible products, capable of withstanding long-term use temperatures up to 650°C. With low thermal conductivity and a microporous structure that locks temperature stability, they effectively reduce heat loss in pipelines, achieving energy savings and consumption reduction. This helps aluminum plants minimize heat loss in steam and flue gas pipelines, lowering workshop energy costs. The product boasts high compressive strength and rigid molding, resisting powderization and cracking. It remains intact under foot traffic in maintenance passageways and wind pressure vibrations, significantly reducing rework and post-construction maintenance costs. Additionally, it features excellent anti-condensation corrosion resistance, tolerating condensation acids and alkalis in flue gas, thereby minimizing corrosion of pipeline base materials beneath insulation layers. This extends pipeline service life, improves high-temperature radiation environments in workshops, mitigates burn risks, and optimizes frontline working conditions.
At the aluminum plant site, calcium silicate pipes are widely used for core components such as hot air ducts for melting furnaces, anode roasting flue gas pipelines, steam networks in electrolysis workshops, and waste heat recovery heat transfer oil pipelines. The inner diameter and thickness can be customized based on different DN sizes. Prefabricated pipe shells offer convenient cutting and assembly, with elbows, tees, and other special-shaped fittings supplied as part of the package, meeting the construction needs of aluminum plants for high-temperature pipelines of various specifications.
As a leading manufacturer, Rosewool Insulation Refractory Co.,Ltd. has been deeply engaged in the production of high-temperature insulation refractory materials for years. All calcium silicate pipe shells undergo rigorous testing for thermal conductivity, strength, shrinkage rate, and other indicators before leaving the factory. The standardized box packaging ensures proper protection, minimizing damage during long-distance transportation. The manufacturer supports customized specifications and bulk supply, offering one-stop services including sample testing, working condition matching, and on-site technical guidance. This eliminates intermediary links, ensuring stable supply and controllable delivery schedules.
