Cover Your Pigs: Urethane pigs should not be exposed to sunlight or other ultraviolet lighting.  Keep Urethane covered with a dark wrap, such as black shrink wrap. Storing pigs outside exposed to the elements is NOT RECOMMENDED.  If left outside, cover pigs with a dark covering such as a tarp and preferably in a shaded area.

Keep Your Pigs Cool & Dry: High humidity will also break down urethane over a period of time. Urethane should be left inside a building if possible.

Cycle Your Pig Inventory: Do you know that urethane pigs have a “shelf life”? Urethane pigs can be stored up to 1 year if stored properly.

Check Your Pigs Regularly: Urethane Pigs are a normal wear item in a pigging system. They need to be inspected periodically and replaced as needed.  It is recommended that pigs be inspected once a month and replaced as necessary. Keep in mind that the number of times a pig runs in a day, week or month varies widely depending on the project/user. Using common sense as to the time frame for checking pigs based on your operation schedule will go a long way. As pig wiper discs approach a factor of 1.005x of the pipe ID, or show signs of tearing, cracking, etc., they should be replaced immediately.
