Thick copper cable-15mm
Assuming it is 15mm. Buy 2 15mm couplers (compression, push fit, pre-soldered or end feed) and a length of 15mm copper pipe. Chop the copper pipe that needs replacing and connect as necessary. If you need any more help just ask.Ans 2 - If you're not familiar working with copper pipe, then it's much easier to get a length of PEX and two 'Sharkbite' or similar push fittings. This generally gives you more flexibilty and allows coverage over areas of the copper pipe that look faulty ( greenish spots) This will cost about the same but is an easier and more reliable repair for the amateur.
15mm beads is =- to how many gm?
15mm = 0.000015km
15mm (millimeters) is about 0.6 inch.
15mm is the same as about 0.6 inches.
If you mean that 15mm is the diameter, then the circumference will be 47.1mm
15mm is 1.5cm (divide mm by 10).
3 x 5 x m x m = 15mm
15mm=1.5cm. 1.5cm=0.015m So, 15mm = 0.015m
% rate = 15mm/10mm * 100% = 150%
