ASTM F3390 Standard
Recently, ASTM International announced that F3390 is the new standard for 3 through 24-inch lined, flexible, corrugated pipe used for land drainage applications. This specification covers all requirements and test methods. The importance of our products exceeding expectations and regulations is forefront in our minds. That’s why FlexCorr has always exceeded this standard. The requirements are intended for all manufacturers to provide non-pressure, or gravity flow, lined flexible annular corrugated polyethylene pipe for subsurface land drainage systems. This news is of great benefit to contractors and customers in the agriculture and construction industries.
