Reducer is one of the chemical industrial Pipe Fittings. It is used in connecting two pipes with different diameters via welding. It usually adopts diameter reduction pressing, diameter expansion pressing or diameter reduction and expansion pressing. Stamping is treated in some reducers. The reducers were divided into Concentric Reducer and Eccentric Reducer.

1. Appearance quality: The surface is flat, and there must be no scratches or stains that impede practical use.
2. Combustion performance: non-combustible.
3. Thermal load shrinkage temperature: 643 degrees.
4. Hygroscopicity: 3.9%.
5. Organic matter content: 2.9%.
Performance fire prevention: The surface material and insulation material of the color composite sandwich panel are non-combustible materials, which can fully meet the requirements of fire protection specifications.
Durability: Various studies have shown that it has been widely used in foreign countries for more than 40 years. The color steel plate treated by special coating has a shelf life of 10-15 years, and then sprays anticorrosive paint every 10 years. The life of the plate can reach more than 35 years.
Aesthetic: The clear lines of the profiled steel plate are as many as dozens of colors, which can meet the needs of any style building and achieve satisfactory results.
High strength: High-strength steel plate is used as the substrate (tensile strength 5600KG/CM). With the most advanced design and roll forming, it has excellent structural characteristics.
Insulation: The commonly used insulation materials for this composite board are: rock wool, glass fiber cotton, polyethylene, polyurethane, etc., with low thermal conductivity and good thermal insulation effect.
Basic parameter material: color steel plate, rock wool http://news.chinawj.com.cn
