4. Characteristics Non-Metallic Pintle Chain & Flight Sludge Collector Designed and Fabricated according to ASME All non-metal sludge collectors are designed and fabricated according to ASME ( American Society of Mechanical Engineers) and they are designed, constructed and installed in accordance with the best practices and methods. High Quality and Environment-friendly Product We manufacture high quality products based on strength, fatigue and wear considerations. We use eco-friendly recyclable engineering plastic, which help promoting harmony between human and nature, saving waste treatment cost as well. Long Operating Life and Low Maintenance Cost Chain and Sprockets are made of material which is non-corrosive and abrasion resistance. In addition, they are designed by technology such as double life type sprocket and save rim. This guarantees long operating life and reduces maintenance cost. Compatibility The main parts of our product are designed to be easily replaceable and compatible with products made from other manufacturers. Linkon chain can be used, being mixed with chains from other manufacturers and simple adaptors make it possible that sprockets can be assembled with various sizes of shaft.
