Detailed size range

Pipes:

Outer diameter range covers a wide range, which varies in different standards and application scenarios. For example:

The outer diameter of seamless brass tubes is 30-400mm and the wall thickness is 3-42.5mm (suitable for industrial fields);

In air conditioning, refrigeration and other scenarios, the outer diameter is 4-80mm and the wall thickness is 0.5-3.5mm;

In other standards, the outer diameter can reach 2-914mm and the wall thickness is 0.2-120mm (covering welded and seamless tubes).

The length is generally 1-12 meters, and customization is supported.

International Standards

C24000 copper tubes comply with a number of international standards, including:

American ASTM standards: such as ASTM B75M (seamless copper tubes), ASTM B42 (seamless copper water pipes), ASTM B111 (condenser tubes);

European standards: corresponding to EN 12163-2016, grade CuZn20 (German DIN standard);

Chinese standards: national standard GB/T 1527-2006, grade H80;

Japanese standards: JIS H3300-2006, grade C2400;

ISO standards: such as ISO 9001 quality management system certification.
