This product is supplied in 3 or 6 meter straight length in the half hard condition, an ideal temper for cold bending and forming max can be easily bent on an appropriate bending machine or for 6 to 22 mm o.d. sizes, with a bending spring.its ease of manipulating and relatively light weight, combine with its ability to withstand high internal pressure makes the ideal products for Hot and Cold water, central heating, gas services, hot and installation. These are the general purpose copper tube for above ground services. Ideal for drinking water, central heating, gas services and cold water, gas various engineering .


 


Also as per BS EN 1057-R220 (Previous Designation BS 2871; Part 1 : Table Y) supplied as either 6m long half or annealed 25M or 23m long coils. With wall thickness aproximately 1.5 times thicker than Max, it is the ideal product for underground application. The extra wall thickness also allows its use on certain pressurized stem installations with maximum working temperature of 205C.


 


These copper tubes are recommended for use on underground services and also suitable for Drinking water, Central Heating, Sanitation Gas and various engineering application.
