Copper Plain Coil

Plain

Product Information

Copper coils (micro-bore) made to EN 1057. Classified as table W in previous versions.
They are particularly suitable where joints and fittings are not preferred.
They are offered in longer lengths than standard straight copper tubes.

Expansion of copper tube

Copper has a coefficient of linear expansion of 17 x 10-6oC. for example, a 10 metre length of copper tube carrying hot water at 600C will increase in length by almost 7mm when heated from 200C. Assuming that temperature cycling of the system is 200C, thaere will be a continuous cycle of expansion and contration of 3.4mm. Refer to table below.
