ASTM B163/ASME SB163 Nickel Alloy Pipe/Tube

• Nickel alloys tube under ASTM B163 can meet the High Strength and corrosion resistance in a range of media including sea water, hydrofluoric acid, sulphuric acid, and alkalies.

• ASTM A163 Coiled Tubing is highly resistant to corrosion in different environments. This tubing enables the speed of the operation to be fast at the same time, it is very safe and easy to run. ASTM B 163 Tubing is used in applications for drilling, logging, fracturing, perforating, and production operations. These tubings have a lower environmental impact.

1. Impact of Pipe Thickness

Pressure Resistance: Thicker pipes can handle higher pressures without failing, making them suitable for high-pressure systems like oil pipelines and heat exchangers.

Strength: Thicker walls give the pipe more strength to resist bending, impacts, and external forces, which is important in demanding environments (e.g., industrial settings).

Thermal Insulation: Thicker pipes better retain heat, which is useful in high-temperature applications, but they can be more expensive and harder to work with.

Corrosion Resistance: Thicker walls provide more protection against corrosion, especially in harsh environments like seawater or chemical plants.

2. Impact of Pipe Diameter

Flow Capacity: Larger diameter pipes can carry more fluid, which is essential for systems with high flow rates (like cooling systems).

Structural Considerations: Larger pipes are heavier and can be more prone to deformation, so they need stronger support structures.

Flexibility: Larger pipes are harder to bend, making them more challenging to install in tight spaces.

Weight: Larger and thicker pipes are heavier, which can increase installation and transportation costs.

3. Combined Effect of Thickness and Diameter

Pressure and Flow: For high-pressure or high-temperature systems, both thicker walls and larger diameters are needed. Thicker walls resist pressure, while larger diameters allow more fluid to flow.

Cost vs. Benefit: Both thickness and diameter increase costs. Thicker pipes offer more durability and resistance to failure, while larger pipes boost flow capacity but are more expensive to produce and install.

Fatigue Resistance: Larger diameter pipes are more prone to stress from pressure changes, but thicker walls help resist this stress.

• Material grade: Choose the appropriate copper alloy (C10200, C68700, etc.) based on the application.

• Pipe dimensions: Ensure the pipe diameter and wall thickness meet the pressure and flow requirements of the system.

• Corrosion resistance: For applications in harsh environments (e.g., marine or chemical industries), ensure the alloy provides adequate corrosion resistance.

• Temperature tolerance: Verify that the pipes can withstand the operating temperatures of the system.

• Weldability: Consider whether welding or other fabrication processes will be required during installation.

ASTM B163 / ASME SB163 pipes, made from copper alloys, generally offer better corrosion resistance and are less prone to rust or degradation in harsh environments compared to carbon steel pipes. While carbon steel may be more cost-effective for some applications, copper alloys have a longer lifespan in environments with high humidity, saltwater, or chemical exposure, which ultimately reduces maintenance costs.
