Class 200 definition

Class 200 means the pipe can withstand a maximum of 200 PSI of internal pressure. Some people will choose this pipe because a residential sprinkler system will never reach 200 PSI, and because it is a cheaper option. However, class 200 pipe is not rated for static pressure conditions, so the 200 PSI limit does not apply in these situations. For this reason, class 200 pipe should not be used for irrigation mainlines that are under constant pressure. Its walls are relatively thin, so it is also more likely to crack if dropped during transport or hit with a shovel. Many times, small cracks in Class 200 pipe are not even discovered until they are in the ground and pressurized.
