Our polyethylene lining technology (DHF-COAT-PE) produces corrosion-resistant pipes lined with low-density polyethylene resin materials originally developed by DHF.

For over a half century since this technology was first commercialized in 1961, we have delivered many products to be installed in various industrial fields and have thus earned a high level of trust from our customers. DHF conducts three types of lining processes (“internal,” “external” and “internal & external”) in response to diverse customer needs.
