Qingdao Ruichang Plastic Machinery Factory is a research and development, production and sales of plastics machinery manufacturing enterprises. Our professional production of prestressed bridge corrugated plastic pipe, prestressed bridge corrugated plastic pipe equipment, plastic spiral prestressed bridge corrugated pipe equipment, corrugated plastic bridge prestressed flat tube equipment, bridges prestressed plastic bamboo corrugated pipe equipment, bridges, pre- stress plastic corrugated pipe machine, plastic corrugated pipe bridge prestressed production equipment, single wall corrugated pipe equipment. Features: low investment, easy operation and high yield. Produce for the bridge construction, anchoring of the plastic corrugated pipe slope (round, flat), is the latest alternative to metal bellows products by our factory technicians hard research, the successful resolution can not be due to the cooling pipe bi thick, resulting in the shortcomings of slow production, to high-quality, high speed, high efficiency. Reduce costs, increase profits. SBG (B) plastic corrugated pipe advantages: material damage as a hole, the slurry is a prestressed concrete structure in the prestressed steel last safety net. Plastic corrugated pipe is a new material into the hole with metal bellows, it has the following advantages: SBG (B) the raw material of plastic corrugated pipe is HDPE. It is far superior corrosion resistance of metal, not afraid of acid and alkali corrosion, which in itself does not corrode, can effectively protect the tendons from corrosion. Many prestressed structure to withstand the severe impact of the outside world, such as deicing salt or salt water. When the post-tensioned structures collapse of the waterproof layer, micro-cracks and drainage facilities, water leakage or failure of the blocking, the tendon will be subject to corrosion. "FIP Construction Guide (1990)" in the "grouting tendons" that no permanent metal pipe corrosion resistance, resistance to water leakage and insufficient to reach the slurry, and tendons. The SBG (B) plastic corrugated pipe can provide a far superior tendon metal bellows barrier protection, to prevent pollution of harmful substances through the pipeline to ensure the post-tensioned structure has better durability; the same conditions, SBG (B) plastic wave tube channel reserved for significantly less than the friction coefficient of metal bellows reserved channel coefficient of friction, tension reduced friction loss of prestressing process. In general, plastic corrugated pipe friction coefficient is 0.14, while the friction coefficient of metal bellows take 0.25; SBG (B) high strength plastic corrugated pipe, not afraid of crushes, difficult to be vibrated holding demolition, the sealing resistance and leakage performance than metal bellows, more suitable for vacuum filling; SBG (B) non-conductive plastic corrugated pipe to prevent stray current corrosion, and metal is good conductor of electricity; SBG (B) plastic corrugated pipe has a better The stamina performance, can greatly increase the ability of anti-fatigue components
