PVC Plastic Manufacturers: Applications, color code and innovations
Polyvinyl Chloride (PVC) piping is the most widely used plastic piping material. PVC piping systems are:
•Provide long service life.
•Easy to install and handle.
•Widely accepted by codes.
PVC plastic pipe is manufactured by extrusion in a variety of sizes and dimensions and generally sold in 10' and 20' lengths. PVC pipe is available in both solid wall and cellular core construction. Cellular core construction involves the simultaneous extrusion of at least three layers of material into the pipe wall: a solid outer layer, a cellular core intermediate layer, and a solid inner layer. PVC pipe is made to conform to various ASTM standards for both pressure and non-pressure applications.
PVC piping is used for:
•Water service lines.
•Various industrial installations.
It can be used under ground or above ground in buildings. It can also be used outdoors if the pipe contains stabilizers and UV inhibitors to shield against ultraviolet radiation and it is painted with a water-based latex paint.
PVC materials are resistant to many ordinary chemicals such as acids, bases, salts and oxidants.
Because PVC piping system components can be manufactured in a variety of colors, identification of application is easy. A common color scheme (although not universal) is:
•White for DWV and some low pressure applications.
•White, blue, and dark gray for cold water piping.
•Green for sewer service.
•Dark gray for industrial pressure applications.
This color scheme has an exception in that much of the white PVC pipe is dual rated for DWV and pressure applications.
PVC piping systems should not be used to store and/or convey compressed air or other gases. PVC piping systems should not be tested with compressed air or other gases either.
PVC piping is recognized as acceptable material for DWV, sewers, and potable water services and distribution in all model plumbing codes. These Codes normally identify acceptable products for specific uses based on the ASTM Standard designation.
Meeting the highest quality standard:
Systematic quality planning in the development of processes and products, quality assurance in the selection and procurement of raw materials, use of latest testing equipments and comprehensive quality control in production, processes etc. ensures consistently superior quality PVC plastic manufacturing and makes them highly dependable.
