Do plastic flanges comply with ANSI 150lbs steel flange dimensions?

Yes
No
Only for larger sizes
Only partially

The correct answer is: Yes

Plastic flanges can indeed be manufactured to comply with the dimensions specified for ANSI 150lb steel flanges. This compliance means that a plastic flange can be designed to fit and mate with existing ANSI 150lb steel piping systems without issues related to size or connection methods. The ANSI (American National Standards Institute) defines specific dimensional requirements for flanges, including bolt hole spacing, flange thickness, and overall size for different pressure ratings. When plastic flanges are made to conform to these standards, they ensure proper sealing and connectivity when used in conjunction with steel flanges. This is particularly important in maintaining the integrity of the piping system and avoiding leaks. While there are considerations for the materials used, such as temperature limitations and chemical compatibility, the primary focus of this question is on dimensional compliance, and as long as the plastic flanges are made according to ANSI specifications, they will fit the dimensions of the 150lb steel flanges correctly.
