The Multi-Flex CIPP Packer/Carriers from Petersen Products are available for virtually any diameter and length using ambient, hot water and steam cure. There are standard items; and the company also makes many custom configurations. They are available with or without a flow-through bypass. A fixed, inflated diameter — independent of the pipeline — bridges across broken sections of pipe, allowing for a continuous, smooth repair. The small-deflated diameter, light weight, and flexibility makes for easier installation and removal through a small opening and confined or manhole spaces. 800-769-4973; www.petersenproducts.com.
