seamless copper tubes

Tubes like as wires are manufactured to standard sizes. Sizes and dimensions of pipes and tubes, and their fittings - inside and outside diameter, weight and more.

bs en copper tubes and pipes standard

Table 1 shows BS EN standards’ titles, categorised by product type, and the BS standards that are replaced. Late in the standardisation process but before national implementation, an EN number is allocated; at this stage drafts are identified with the prefix ‘pr’. In due course, the BS EN implementation uses the same number.

Table 2 shows BS historic standard numbers in numerical order and their replacement BS EN standards.
