The experimental test

HDPE double corrugated large-diameter drainage) pipe is high density polyethylene as the main raw material, by inside and outside the common extrusion molding, extrusion machine inner surface level off is smooth, the outer wall terraces fluid lines, with annular outer wall structure, and have measured layer between the internal and external wall.

Confidence comes from quality and quality.

The company has built three manufacturing bases of steel belt reinforced polyethylene spiral corrugated pipe and MPP, PE pipe production area, hot dip plastic steel pipe and composite pipe production area and glass pipe production area. 

Do the company in line with, do strong, do big goal of pipeline industry, adhere to the tenet of "quality first, customer supreme", the high-quality goods production to meet customer needs is our basic work, bring tangible benefits for customers is our pursuit of the ultimate goal.
