HDPE Production Line of Corrugated Pipe for Pre-Stress Cement:
HDPE production line of corrugated pipe for pre-stress cement. When the hole material is destroyed, the cement is the last safety serene of pre-stress steel in the pre-stress concrete structure. As a new type hole material, compared with mental corrugated pipe the tube has the following advantages: the raw material of SBG(B) plastic corrugation pipe is HDPE. Its corrosion resistance is far superior to mental with acid and alkali corrosion, and it can protect pre-stress tendon from corrosion effectively. Many pre-stress structures stand severe influence in external world, such as deice salt or brine. The pre-stress tendon may be eroded when post-tensioned member becomes a failure due to collapse of waterproof layer, micro-fissure leakage and obstruction of drain equipment.
