It is not generally realised how great an effect small obstructions can have on the flow pattern of water in a pipe-work system and the extent to which they can induce turbulence and cause corrosion-erosion. For example, it is most important, as far as possible, to ensure that copper tubes cut with a tube cutter are deburred before making the ...
About 20 pinhole leaks have been fixed to date on that section, and work continues to locate and repair others. Why pinhole leaks cause pesky problems for the Quemahoning's 66-inch diameter steel ...
Pipes are often marked to show the insertion depth, so if you cut at a mark, then insert the pipe up to the next mark, you will have a good connection. Hepworth pipe has always had this feature, for example. Making a mark before insertion is advised on pipe that is not pre-marked (e.g. copper pipe). Hepworth supply an insert with bulges on the end.
Edwards's research in the mid-1990s focused on an increasing incidence of pinhole leaks in copper water pipes. Homeowners contacted him about the leaks, some of which were occurring 18 months after installation. [2] After a century of using copper for water pipes, the expectation is that they will last for 50 years in residential applications. [2]
If your pipes are exposed, we recommend using a hair dryer, heating pad, or space heater to help thaw your pipes and get water moving again. (Note: Never leave the latter two methods unsupervised.)
Copper and its alloys, mild steel, and in some cases small diameter stainless steel pipes are most commonly reamed with hand tools. [ 15 ] Copper is perfectly machinable, a quality tool successfully performs wall deformation, the surface remains smooth, the wall thickness is almost the same, and the material retains a homogeneous structure.
