1.) Working pressure is the maximum pressure rating of the joint and is based on its capability to resist thrust due to internal pressure. If higher working pressure is required, check with AMERICAN.
2.) Dimensions subject to change at our option. Check with AMERICAN if smaller or exact dimensions are required.
3.) Intended for Horizontal Directional Drilling (HDD) applications. The tabulated values are based on Pressure Class 350 Pipe thickness. Contact AMERICAN when higher pulling loads are required or when it may be desirable to use lesser pressure class pipe. Flex-Ring pipe may be available for greater pulling loads than indicated in the tabulated values.
4.) Based on weight of empty (full of air) pressure class 350 Flex-Ring joint pipe with standard cement lining immersed in water. Positive numbers indicate such pipe will float.
