PIPING

2.28 CHAPTER TWO

Cast Copper Alloy
Fittings of this material can be used with any copper or brass pipe. They are available with
solder ends only. These fittings should conform to the following standards:
1. ANSI B 16.18: Cast Copper Solder Joint Pressure Fittings
2. ANSI B 16.23: Solder Joint Drainage Fittings
3. ANSI B 16.26: Cast Copper Alloy Flared Fittings

Wrought Copper and Copper Alloy
Fittings of this material can be used with any copper or brass pipe. They are available with
solder ends only. These fittings should conform to the following standards:
1. ANSI B 16.22: Wrought Copper and Copper Alloy Solder Joint Pressure Fittings
2. ANSI B 16.29: Solder Joint DWV Drainage Fittings

Acid-Resistant Cl

Acid-resistant fittings are of the same material as the pipe and conform to the same standards.

Glass
Glass fittings are of the same material as the pipe and conform to the same standards.

Stainless Steel
Stainless steel fittings are of the same material as the pipe and conform to the same standards.

Bronze

Cast bronze fittings shall conform to ANSI/ASME B 16.15 and are available in class 150
and class 250 threaded ends. Flanges conforming to ANSI B 16.24 are available in sizes
2 1/2 in (65 mm) and larger.

Dielectric
Dielectric fittings are actually adapters used to connect any pipe containing copper with any
pipe containing iron to prevent the galvanic action between these dissimilar metals from
causing corrosion failure. The fitting itself is constructed so that insulation prevents either
connecting pipe from coming into direct contact with the other.

Plastic Fittings

Plastic fittings can only be used with the individual plastic pipe materials from which they
are made. Nationally recognized standards are not available for many plastic fitting materials
