Weldable 122 Copper Tubes
- Yield Strength: Not Rated
- Hardness: Not Rated
- Temper: H02 (1/2 Hard)
- Heat Treatable: No
- Specifications Met: ASTM B251
The addition of phosphorus makes 122 copper easier to weld and braze than 110 copper. It has excellent resistance to corrosion caused by water, soil, and weather, making it the go-to material for plumbing and underground applications. It’s also used for storage tanks and chemical equipment. It's less electrically conductive than other copper. Each tube fits inside the next larger size for creating telescoping tubes.

Marine-Grade Copper Nickel Tubes
- Yield Strength: 15,000 psi
- Hardness: Not Rated
- Temper Rating: Softened (Annealed)
- Heat Treatable: No
- Specifications Met: ASTM B111, MIL-T-15005
Commonly used in water treatment plants, these tubes withstand salt water and can be used to make shims, ferrules, and washers. Made from an alloy known as cupro nickel, they resist corrosion and stress-cracking from chlorides better than stainless steel. They also resist rusting, withstand humidity, and will not corrode from algae and barnacle build-up. However, these tubes are more likely to develop pits from sulfides than stainless steel. A good choice for cryogenic processing plants, these tubes remain ductile and strong even at freezing temperatures.
Like other copper alloys, these tubes are easy to machine. Spot weld, braze, and solder them to join them with like materials. They conduct electricity and heat, so they are often used in heat exchangers and condensers in HVAC systems and applications where fluids need cooling or heating. When cleaned regularly these tubes resist bacteria, fungi, and viruses, so they can be used in high-touch areas on ships and in healthcare settings.

Copper-Nickel Unthreaded Pipe
- For Use With: Air, Natural Gas, Oil, Water, Salt Water
- Pressure Class : 200
- Specifications Met: MIL-T-16420
- Fittings: Use Class 200 copper-nickel
Designed for salt water applications, this pipe is made of copper-nickel, which has excellent resistance to stress cracking and better corrosion resistance than most stainless steel alloys. Pipe is also known as Pressure Class 200 pipe. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. Pipe is seamless, which provides a smooth interior for unrestricted flow.
