With the expansion of production and urban development, pipelines for conveying heat, air conditioning, and other utilities are growing increasingly longer. As a key component in minimizing heat loss from insulated pipelines, the thermal insulation and heat-shielding properties of pipe supports have garnered significant attention. To eliminate thermal bridges and achieve energy conservation, thermal materials for pipe supports continue to evolve. Vermiculite, with its superior insulation properties, has entered the field of pipeline engineering. Through years of production, research, and practical application, expanded vermiculite has been developed as the primary skeletal material for pipe supports. Combined with auxiliary materials and processed through rigorous steps—including precise blending, mixing, static pressing, molding, drying, and inspection—vermiculite pipe supports are manufactured. These supports offer excellent fire resistance, thermal insulation, high compressive strength, strong bonding, extended service life, and soundproofing properties. They effectively eliminate thermal bridges, achieving energy-saving insulation goals. Upon entering the market, they gained widespread acceptance, with their application areas steadily expanding.
The primary raw material used in vermiculite pipe hanger production is expanded vermiculite, an inorganic material with excellent thermal insulation properties. A mixture of 80% expanded vermiculite, 15% high-temperature resistant adhesive, and 5% other additives is thoroughly blended. The resulting mixture forms into balls with a moisture content that allows it to be kneaded by hand without sticking. This mixture is placed into molds and subjected to high-temperature compression for approximately two hours. After removal from the molds, the product cools naturally. Vermiculite pipe supports can be custom-produced to fit various pipe dimensions and user requirements. They offer significant advantages in application, including non-combustibility, thermal insulation, soundproofing, long service life, easy installation, and energy efficiency with environmental benefits.
As a Class A1 non-combustible inorganic material, vermiculite pipe supports exhibit excellent flame retardancy with a fire resistance rating exceeding 3 hours. They release no toxic gases under high temperatures or fire conditions. Their lightweight nature, low thermal conductivity, and minimal water absorption make them ideal for thermal insulation, cold preservation, and heat shielding applications. Vermiculite pipe supports maintain dimensional stability even under extreme conditions—from sub-zero temperatures (below -163°C) to high heat. Their high compressive strength and bending resistance, combined with the porous nature of expanded vermiculite, make them an effective acoustic barrier. They significantly reduce operational noise from pipelines, enhancing living environments. Vermiculite pipe supports boast a long service life, matching the lifespan of buildings. Installation is straightforward with short construction cycles, offering energy efficiency and environmental benefits. The material can be crushed and reused as filler, causing no environmental pollution and enabling sustainable production.
Due to the aforementioned advantages of vermiculite pipe supports, they have gained widespread recognition and application not only domestically but also globally. Their application scope is extensive, typically suitable for various pipeline systems requiring thermal insulation and flame retardancy, such as heating, petroleum, chemical, power, and metallurgical industries. They are also widely used in locations needing support for thermal insulation, including pipe brackets, pipe seats, and suspension hangers. As awareness of vermiculite pipe supports continues to grow, this highly advantageous product will find its way into even more fields.
