What are the common specifications for brass tubes?
The common specifications for brass tubes primarily include the following aspects: Outer Diameter (OD)
· General range: 3mm to 250mm. Inner Diameter (ID)
· Variation range: Varies depending on the outer diameter and wall thickness; specific values must be determined based on actual requirements. Wall Thickness (WT)
· General range: 0.5mm to 50mm. Length (L)
· Common types: Generally fixed lengths, with specific lengths determined based on order requirements. Specific specification examples
· Small specifications: e.g., 6mm × 1mm, 10mm × 1.2mm. These specifications are typically used in precision instruments, small refrigeration equipment, or household hot/cold water systems, as they are compact and lightweight, facilitating installation and maintenance.
·Medium-sized specifications: e.g., 20mm × 2mm, 25mm × 2.5mm. These are widely used in building plumbing systems, central air conditioning system condensate pipes, and certain small-scale industrial fluid transmission applications, balancing cost and performance.




·Large specifications: such as 50mm×3mm, 100mm×4mm, and above. These specifications of copper tubing are primarily used in large-scale refrigeration equipment, industrial cooling systems, or special-purpose fluid transmission. Their high strength and excellent corrosion resistance meet the demands of harsh working environments.
Purchase Recommendations
·When selecting copper tubing, specifications should be determined based on actual requirements. For example, smaller piping systems may be more suitable for 35mm or 38mm copper tubing, while larger projects or applications requiring higher flow rates may be more suitable for 40mm to 54mm copper tubing.
In summary, copper tubing comes in a variety of specifications, and selection should be based on specific application scenarios and requirements.
