The full name of PP-BHM corrugated pipe is Buried Drainage High Modulus Copolymer Polypropylene (PP-BHM) pipe, which has high stiffness, high impact strength (especially in low temperature conditions), good long-term performance and excellent chemical resistance. At the same time, based on the above characteristics, PP-BHM also expands its application field to other non-pressure systems, especially soil and wastewater pipeline systems and power cable protection systems.

the emergence of high modulus, block, copolymer, polypropylene (PP-BHM) pipelines will also solve many existing old problems, major problems and problems in the field of municipal buried drainage and sewage treatment, wastewater treatment and new rural construction. It provides an economical, reliable and lasting solution, which will bring great economic and social benefits to our country, our province and our city.

Compared with developed countries, China is still relatively backward in municipal utilities. There are many types of large-diameter pipelines currently used in buried drainage and sewage, and each has its own defects. Such as PVC-U double-wall corrugated pipe, low temperature brittleness is poor, the product diameter is limited to 600mm; PE double-wall corrugated pipe has low stiffness, variable type, large backfill engineering, and is easy to cause road collapse; concrete pipe has short service life, easy corrosion and leakage, and large installation and transportation engineering; steel pipe has high cost, easy corrosion, and large installation and transportation engineering.
