At present, environmental pollution has been increased for leakage water of sewage or waste. Our company, based on technologies

and experiences to develop double wall PE Pipe facility for sewage and waste water, and connection pipe, has manufactured

facilities having high productivity and reliance. Since facilities have manufactured with minute design, rigidly selected parts and rigid

quality control,they have high reliance. With safe processes, it has high pipe stiffness, safety in weight per meter, dimensional safety,

and productivity. We will present technological assistance for various products, construction technologies in connection pipe

manufacture, surrounding facilities, new product development technologies.
