Multi-Flex CIPP Packers from Petersen Products are available for virtually any diameter and length using ambient, hot water and steam cure. They are available as standard items and many custom configurations, with or without a flow-through bypass. Since they have fixed inflated diameter independent of the pipeline, they bridge across broken sections of pipe for a continuous, smooth pipe I.D. The small deflated diameter, lightweight and flexibility allow easier installation and removal through a small opening and confined or manhole spaces. 800-769-4973; www.petersenproducts.com.
