Plastic flanges are rated for what service weight?

Plastic flanges, often used in systems that handle lower pressures and specific types of fluids, are typically rated for a service weight of 150 pounds. This rating signifies the maximum weight or pressure that the flange can effectively hold without risking failure or leaks.

In applications where plastic flanges are deployed, it's essential to ensure that they are compatible with the media they will carry, as well as the operating conditions they will face, including temperature and pressure. Ratings like 150 pounds indicate that these flanges can maintain structural integrity under those performance parameters, making them suitable for various plumbing, industrial, and residential applications.
