HDPE-M corrugated pipe

Product Introduction

HDPE-HM drainage pipes are double-wall corrugated pipes manufactured through an extrusion process. They are made from a specialized compound—primarily modified high-density polyethylene (HDPE) blended with specific additives—featuring a closed, corrugated outer wall and a smooth inner wall. These pipes offer high resistance to external pressure, a low coefficient of friction, excellent impact resistance, long service life, and superior wear resistance. They are suitable for the transport of rainwater and sewage in sectors such as municipal engineering, transportation infrastructure, agriculture, and water conservancy.
