Product Description

ZRD INDUSTRY ROCK WOOL PIPE

The rock wool fiber is rolled with a mold and formed by high temperature and solidification. For the convenience of installation, a unilateral slit is made along the axial direction of the shell, which is convenient for construction and can ensure that the shell is closely matched with the pipe that needs to be insulated. The outer surface of the shell can be polished according to customer requirements to ensure accurate and consistent insulation thickness. Hydrophobic and low-chlorine products can be produced according to requirements, and aluminum foil glass fiber cloth (ALGC) and other veneer materials can also be added to the surface.

Product Highlights

1. Superior Thermal & Energy Efficiency
Excellent Insulation: Features a low thermal conductivity (≤0.039 W/m·K at 50°C), effectively reducing heat loss and energy consumption.

High-Temperature Stability: With a maximum operating temperature up to 650°C, it is suitable for high-heat industrial environments.

2. Safety & Fire Protection
Non-Combustible: Achieves A1 non-flammability rating with smoke density <25.

Eco-Friendly: Asbestos-free and free of CFCs, HCFCs, and HFCs, ensuring environmental safety.

3. Durability & Corrosion Resistance
Anti-Corrosion: Specifically designed with low chloride content (≤10 PPM) to prevent corrosion of stainless steel pipes (per ASTM C795).

Hydrophobic: Offers a hydrophobic rate of 99%, effectively resisting moisture absorption (≤0.02 vol%) and preventing condensation.

4. Precise & Easy Installation
Customizable Fit: Manufactured using molds to ensure accurate and consistent insulation thickness.

Convenient Design: Features a unilateral slit for easy installation, ensuring a close fit with the pipe surface.

Application

IPS series products are mainly used for thermal insulation of power plants or small-diameter cold and hot pipelines to protect personal safety, reduce or avoid condensation, and reduce noise.

 
The vertical seams of adjacent IPS series products need to be staggered. The vertical and horizontal seams of two-layer IPS series products need to be staggered, and the distance between the staggered seams is recommended to be greater than 150mm;
Each IPS series product is fixed on the pipe by two steel bars at both ends, and the steel bars at both ends are more than 100mm away from the edge of the pipe shell;

Company Profile

Nanjing Zhongrunda distributes first-line rock wool brands at home and abroad, such as: Rockwool Rock Wool, Owens Corning Rock Wool, ABM Rock Wool, Kaihua Rock Wool, Tongtian Rock Wool, Dragon Brand Rock Wool, Jinyu rock wool, etc. Rock wool products have the characteristics of green environmental protection, low thermal conductivity, high temperature resistance, heat insulation, sound insulation, flame retardant, and antifreeze. Thermal insulation and sound insulation projects in construction, transportation, shipbuilding and other industries. Nanjing Zhongrunda has always been adhering to the core purpose of "doing our best to provide customers with high-quality rock wool products", promoting the high-quality sustainable development of environmental protection and energy-saving materials in the new era of society, and striving to provide what it can for a low-carbon society and socialism with Chinese characteristics in the new era. shelp.

Company Vision: To become a high-end rock wool integrated service provider in China and to be a pioneer in the field of new building materials in China.

The company's core values: quality, service, efficiency, responsibility, innovation.

In recent years, in order to open up the international market, Nanjing Zhongrunda has determined the core goal of international market development of "subdividing the vertical field of rock wool and broadening the new field of thermal insulation materials". Subdividing the vertical field of rock wool is mainly to segment the market. In the vertical subdivision fields such as rock wool shell, rock wool felt, and agricultural rock wool, we will dig deep into the target customers. Our rock wool felt rolls, rock wool pipe shells, and agricultural rock wool are exported to Southeast Asia, North America, South America, and the Middle East. Especially the Southeast Asian market is the core market of Nanjing Zhongrunda New Materials, and is deeply loved and trusted by customers from the Philippines, Vietnam and other countries.

ZRD rock mineral wool products are made from natural rock such as basalt and dolomite.The natural rock are melted into melts in cupola at a high temperature about 1500°C.And the melts lava is then pour to high speed spinners through which the melts get into fibers.After that fibers are collected together to form the original wool mat through negative pressure resulted from suction. The original wool mats then pass through pendulum, crimping and pressing process, get into the curing oven through which the wool mats are cured and shape up to different kinds of products such as rock mineral wool board, rock mineral wool blanket, rock mineral wool strip and rock mineral wool pipe section etc with different usage.
