The measurement table serves only as a guideline. Repairs are applied manually and the result may vary depending on the experience of the person applying it. Always use the entire roll. The table is for standard pipe sizes; the actual diameter may vary with pipe type and casing thickness. When repairing a cased pipe, refer to the values given for the next pipe diameter. Application on cased pipes may require additional products.
