QUALITY CONTROL
Batching and mixing operations in the industry’s premier plants have been upgraded over the past 10 years. Characteristics of this operation of the pipe production process normally include:
Computer controlled weighing and proportioning systems
Computer controlled mixing systems
Automated recording systems
Absorption testing
The American Concrete Pipe Association offers an on-going quality assurance program called the “Quality Cast” Plant Certification Program.
This 124-point audit-inspection program covers the inspection of materials, finished products and handling/storage procedures, as well as performance testing and quality control documentation. Plants are certified to provide storm sewer and culvert pipe or under a combined sanitary sewer, storm sewer, and culvert pipe program.
