Seamless copper tube manufactured to ASTM B75 – Standard Specification for Seamless Copper Tube may be either round, square, or rectangular and is suitable for general engineering applications.

Tubes meeting this standard may be furnished in any of several tempers (H55, H58, H80, O60, or O50), ranging from light drawn (usually limited to round tubes) to light annealed.

It is the responsibility of the purchaser, when ordering, to provide the requirements for:

Alloy (UNS number)

Temper

Dimensions (diameter, wall thickness, or distance between parallel surfaces)

Form (straight lengths or coils)

Total length or number of pieces of any particular size

This requirement means this tube is typically a special order item rather than a standard stocked material. We mainly provide this alloy where no corrosion resistance is necessary and high heat transfer is required.

We maintain an inventory of this alloy for faster delivery to our customers. C12200 DHP copper is very easy to work with and is used in a variety of industries, from commercial and plumbing applications to industrial and heat transfer tubes.

Chiller applications: C12200 DHP copper is also used in chiller applications where tubes are finned or other surface enhancements are applied. (This is also done with C70600 copper nickel 90/10; however, the majority of chiller tubes are made from C12200 DHP copper.)

We are experienced in analyzing your tubing needs whether in copper, nickel, steel, or otherwise. Our professionals have over 20 years of combined experience in copper alloys and will guide you through the tube selection process.

While many suppliers around the world supply copper tubes for a variety of applications, we focus on those high-touch applications where quality, tolerances, traceability, and special requests are needed.

We provide C12200 DHP copper according to the following standards:

ASTM B75

ASME SB111

ASTM B111

MIL-T-24107B

Q1: What does DHP stand for in C12200 DHP copper?
A: DHP stands for "Deoxidized High Phosphorus." It indicates that the copper has been deoxidized with a higher phosphorus content (typically 0.015-0.040%) to prevent hydrogen embrittlement during welding and brazing.

Q2: What is the difference between ASTM B75 and ASTM B111 for C12200 tube?
A: ASTM B75 is a general specification for seamless copper tube for engineering applications. ASTM B111 is specifically for seamless condenser and heat exchanger tubes. B111 has tighter dimensional tolerances and additional testing requirements for heat transfer service. B75 is suitable for plumbing and general use.

Q3: Is C12200 suitable for heat exchanger applications?
A: Yes. C12200 is widely used in heat exchangers for fresh water, HVAC, and refrigeration service. Its high thermal conductivity (approximately 340-360 W/m·K) makes it an excellent choice for heat transfer. However, for seawater service, other alloys such as C70600 or C71500 are recommended.

Q4: What is NSF-61 certification and why does it matter?
A: NSF-61 is a standard for drinking water system components. It certifies that materials do not leach harmful contaminants into potable water. NSF-61 certification is required for plumbing tubes used in residential and commercial drinking water systems in many jurisdictions.

Q5: What tempers are available for C12200 tube?
A: Common tempers include: H55 (light drawn), H58 (light drawn for plumbing), H80 (hard drawn), O60 (soft annealed), and O50 (light annealed). Annealed tempers (O60, O50) are recommended for bending and tube expansion. Hard drawn (H80) is used where higher strength is required.

Q6: Can C12200 be used for finned tubes?
A: Yes. C12200 is commonly used for finned tubes in chillers and other heat exchanger applications. Its good ductility allows it to be formed into integral fins or have external fins attached.

Q7: What is the difference between C12200 and C12200 DHP?
A: They are the same alloy. C12200 is the UNS designation. DHP (Deoxidized High Phosphorus) describes the manufacturing method and phosphorus content range. The terms are used interchangeably.

Q8: What is the maximum temperature for C12200 in continuous service?
A: For continuous service, C12200 is typically limited to 200°C (400°F). Above this temperature, strength decreases significantly and oxidation accelerates. Short-term exposure to higher temperatures may be acceptable depending on the application and stress levels.

Q9: How does C12200 compare to C70600 (90/10 copper-nickel) for chiller tubes?
A: C12200 has higher thermal conductivity (approx. 360 vs 45 W/m·K) and lower cost. C70600 has better corrosion resistance, especially in seawater or brackish water. The majority of chiller tubes are made from C12200 because fresh water or treated water is typically used in closed-loop chiller systems.

Q10: Do you supply C12200 tube in small quantities for repair work?
A: Please contact us directly with your dimensional requirements and quantity. We support both small repair orders and large production quantities depending on stock availability and current mill lead times.
