AOC Plastic Piping Products
AOC has aggressively been responding to the needs of the times from a global perspective as a piping materials manufacturer.
Asahi AV "Asahi" Valve in AOC is a leading worldwide brand in PVC valves but, due to the nature of the product, it is not often that it is exposed to the public eye. For example, behind an aquarium that uses large volumes of seawater, PVC pipe and fittings, Asahi AV "Asahi" valves are used to form a critical lifeline for the fish to survive. Valves manufactured by AOC play critical roles in the chemical solution lines in large factories that are not frequented by the general public. In the area of fresh water, Asahi AV "Asahi" valves play a leading role underground as gate valves in water supply agricultural irrigation water applications.
AsahiAV
Asahi AV piping materials are products that have long history and are trusted yet full of fresh ideas and technology. Asahi AV piping material products began to be manufactured and sold in 1952 as PVC valve (Asahi AV Valve).
Since that time efforts toward quality improvement and quality enhancements were made and enable AOC to maintain its leading share. Further, by aggressively developing new products, plastic piping material technologies and making improvements to existing products, AOC has expanded into peripheral areas while meeting the requirements of customers.
Asahi AV piping materials made of plastic excel in heat resistance, cold resistance, corrosion resistance, chemical resistance and abrasion resistance and are strong yet light and have been widely used as components supporting the foundations of plumbing facilities and have become indispensable in factories, buildings, water and sewage (underground), agricultural irrigation equipment, fish farming facilities, amusement facilities and the like.
AOC as the leading manufacturer offer multiple product lines of differing materials and sizes within one product series and are equipped to respond to specialized orders able to meet any piping material needs.

Product-Related Information
Engineering
AOC engages in the design and installation of the piping line using our products.
A long and successful track record has been established in the chemical piping for steel and chemical plants, aquarium equipment, water and sewage and agricultural irrigation facilities. In addition, the company has established a reputation in the laying of pure water line pipes that demand sophisticated construction expertise.
Product sale is conducted with the manufacturing of processed products using resins and construction utilizing valves with various functions, as well as piping materials that emit miniscule amounts of dissolved impurities in semiconductor and chemical plants.
Moreover, the company offers sludge reduction equipment, deodorization and desalination equipment that applies the company's engineering technology and environment related technology. In each case, chemicals are not used, and equipment utilizes the power of nature to the best extent possible.
AOC engineering business is active, not only in Japan, but also around the world including the rapidly expanding Asian countries.
Plant Piping Design & Equipment Construction
AOC undertakes design and construction utilizing its own products (Valves, Pipes, Fittings, etc) for a variety of applications.
Examples:
- High Purity Water Piping, Drain Piping & PVC Ducts for Semiconductor Plants
- Piping for Aquariums
- Piping for Steel and Chemical Plants
Design and Production of Devices
Asahi Humans Reactor "Osiris"
Design and Production of Liquid Phase Deodorization Systems
Desalination Equipment
AOC designs and constructs desalination equipment using a desalination device, ACILYZER. Desalination device uses an ion exchange membrane to remove salt from water containing large amounts of salt to make it suitable for drinking water.
- Produce Drinking Water from Salt Water
- Removal of Nitrate Nitrogen from Drinking Water Source
- Reduction of Electrical Conductivity in Ground Water and Creek Water
Note: ACILYZER is a registered trademark of desalination device manufactured by Asahi Kasei Corporation
Foam Separator
It is a device that, using a self-feeding aerating device, creates tiny bubbles in the water continuously forcing out and discharging the pollutants.
It is used in maintenance of water quality in such facilities as aquariums.
Due to the simplicity in the structure, it is easily maintained, has wide applicability and is a device that is expected to gain installation base in sewage treatment.
AV Pipes and Prefabricated Products
The company engages in the manufacturing of pipe & fittings using FRP reinforced PVC pipe and production of prefabricated products. The company is also engaged in dispatch of Engineers to supervise installations.
