Polyvinyl Chloride is commonly known as PVC. The attractive property of PVC makes it an ideal choice in food industry. It is the third-most widely used plastic after polypropylene and polyethylene. It is used in construction because it is cheaper and stronger than the traditional alternatives like ductile iron or copper. It can be molded and made softer by adding plasticizers. The most common ones being phthalates, therefore it is used in upholstery, clothing, electrical cable, inflatable products, insulation and in various other applications.
PVC in its purest form without any plasticizer is a brittle and white solid. It is insoluble in alcohol and slightly soluble in tetrahydrofuran. They are widely used in various industries and available in various sizes and colors. These include citrus/juices, beer, wine, potable water, grain and flour. PVC hose is used for bulk transfer of food products with the help of suction or pneumatic systems. They are exclusively manufactured to preserve the quality of food and prevent its contamination from foreign elements.
Such pipes are extensively used in food manufacturing units and to carry out production in hygienic and safe environment. Some of the common wet dry applications include bulk food processing, load cell connections, process transfer, pump vibration damping, wash down station and others. In general flexible hose are is used to supply wine, beer, water, milk, soft drinks, fish and flour.
To maintain its flexible characteristic food hose pipes are made up PVC. However, they also have an internal stainless steel wire coupled with a helical structure to provide durability and strength. It is much different from fuel hose or other suction pipes. Since they are non-metallic in nature they avoid contamination of food due metal corrosion. Food hose pipes are made up of non-toxic compound which is chemical resistant. It is also colorless and odorless which helps to preserve the actual taste of the product. Lastly, it is durable and can sustain high pressure supply which is important for beer and wine industries.
