Good on-plastic HDPE double wall corrugated pipe gold low temperature embrittlement temperature impact resistance HDPE double wall corrugated pipe is -70 ℃. In general, low temperature (above -30 ℃) does not have to take special protective measures during construction, winter construction is convenient, and double-wall corrugated pipe, HDPE double wall corrugated pipe has a good impact resistance. Chemical stability, good Since polar molecules do not double-wall corrugated HDPE pipe factory, so excellent chemical stability. Apart from a few strong oxidant double-wall corrugated pipe, most of them can not afford to undermine the role of chemical mediators. Soil general use of the environment, electricity, acid factor will not damage the pipeline, no bacteria, no scaling, its circulation area will not increase over time and reduce run. HDPE double-wall bellows HDPE double wall corrugated pipe introduced double-wall corrugated HDPE pipe can be directly connected via a short pipe and manholes, which directly or pouring concrete brick wall in check, because the pipe outer wall of the annular ribs, with only The role of water back stop. For lots of silt soil or flow of sand soil backfill should make the transition section to ensure the construction quality. Double-wall corrugated pipe _-plastic (certified) _ wall bellows made of gold on Xiongxian-plastic Products Co., Ltd. to provide the gold. Plastic products Limited (www.jinshangtongsj.com) on gold Xiongxian Hebei Baoding, composite pipe leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. On gold-plastic leadership with the staff warmly welcome all inquiries negotiations to create the gold-plastic better future.
