Product Description

ASTM B111 UNS C12200 / TP2 Alloy Seamless Tube DHP Copper Tube Heat Exchanger Tube

ASTM B111 UNS C12200 Seamless Red Copper Tube (DHP / TP2) is the industry standard for heat exchanger tubes requiring high thermal conductivity, excellent weldability, and superior resistance to corrosion in water environments. Its deoxidized chemistry ensures reliability during brazing and welding operations commonly performed during heat exchanger fabrication.

Key Properties of ASTM B111 UNS C12200 Seamless Red Copper Tube DHP Copper Tube

Weldability: Excellent. The deoxidized nature of C12200 allows it to be welded (gas, arc, resistance, brazing) without the risk of hydrogen embrittlement (which plagues oxygen-bearing coppers like C11000).
Corrosion Resistance: Excellent resistance to non-oxidizing acids, fresh water, and seawater. It is widely used in plumbing and marine applications.
Conductivity:
- Electrical Conductivity: Approximately 85% IACS (International Annealed Copper Standard).
- Thermal Conductivity: Very high (approx. 339–380 W/(m·K)), making it ideal for heat exchangers.
Formability: Excellent ductility; it can be easily bent, flared, and expanded.

Selection Criteria Matrix (for Tubing / Heat Exchangers)

Requirement	Recommended Grades	Reason
Fresh water, steam, HVAC	C12200 (DHP)	Good corrosion resistance, excellent thermal conductivity, easy to braze/weld, cost‑effective.
Seawater, brackish water	C70600 (90/10 Cu‑Ni)	Superior resistance to pitting, crevice corrosion, and erosion. C71500 for higher velocity (>3 m/s) or polluted seawater.
High‑velocity seawater with moderate chlorides	C68700 (Al brass)	Lower cost than Cu‑Ni; good for once‑through cooling where velocities are controlled (1.5–2.5 m/s).
Welding / brazing required	C12200, C10100, C10200, Cu‑Ni alloys	Deoxidized or oxygen‑free grades avoid hydrogen embrittlement.
High electrical conductivity	C10200 (OFHC) or C11000	But note: C11000 cannot be welded.
Ammonia / ammonium compounds	Avoid brasses (dezincification risk); use Cu‑Ni or C12200	Ammonia attacks brasses (stress corrosion cracking).
High temperature (>250°C) in reducing atmosphere	C12200 or Cu‑Ni	Oxygen‑bearing copper (C11000) fails due to hydrogen embrittlement.

Application

Heat Exchangers: Shell and tube heat exchangers.
Condensers: Steam condensers in power plants and marine vessels (shipbuilding).
Evaporators: HVAC and refrigeration systems.
Hydraulic Lines: Oil cooler tubes.
Plumbing: Though B111 covers heat exchangers, the same material (C12200) is also the standard for water service lines and HVAC refrigerant lines (ACR tubing) under other standards like ASTM B280.

Tube ends were clean, dimensions consistent. Our crew didn't run into fit-up issues.

Using these in mining cooling equipment under pretty rough conditions. They’ve been running for a month now and are super stable.

No leaks, no fin damage, performance consistent. Heat transfer hasn't dropped, so fouling doesn't seem to be a problem yet.
