2012年10月4日 · I have a 1meter roll of 10mm copper microbore pipe that is rolled. I need to straighten a 50cm stretch so that can get it through a wall and solder a elbow to keep it flush against the wall. However, unlike the plastic pipe the copper is rigid so unrolling it seems like it might kink or puncture the pipe.

2011年6月20日 · Hi, Can anyone recommend a good way of bending 10mm pipe? I only need to bend it through 90 deg. Are mini pipe benders any good? The bend will be below the point at which it rises to the rad. many thanks...

2013年10月20日 · The warranty cannot be invalidated by using two pipe materials. The only bit that will cause polypipe concern is the transition points, and they make great claims for compatability with other eg: copper systems. The new layflat Speedfit is much easier to use, Im doing 350m tomorrow. Radiators off manifolds, no underfloor joints.

2012年5月14日 · Once caught an instrument technician (well that's what he was calling himself) straightening 1/4" copper tubing, in the days of 3-15psi controls, using a turfor chain block to stretch out the kinks. What started life as non-straight …

2009年2月28日 · I wouldn't use Speedfit or Hep have been to numerous failures of fittings on both Speedsh*t - fittings go brittle after a few years, discolour (go brown) and then fall to pieces HepPooO - the green grip rings have a nasty habit of splitting and or not gripping the pipe then pipe even with inserts just pops out of the fitting you have been warned

2014年12月19日 · It happens when force is removed from the pipe bender, then re-applied. i.e the plumber bends a 90 degree bend then once he lets go there is spring in pipe trying to straighten out, so he bends it some more. If he's good with a bender, he'll over-bend it by just the right amount so once it springs back it's as he wants it.

2007年11月9日 · Just use chrome pipe to towel rail, i use this as it looks much better than copper and is already coated. You will soon learn that tilers are not good at listening to instructions given by plumbers, in fact , this may upset them but they have caused me so many problems its unreal.

2010年5月6日 · 1. Normally accepted maximum bend radius is 4 x pipe diameter, so a minimum radius of 60 mm for 15 mm pipe. 2. You can bend 180 degrees with a spring. It can be awkward to get the spring out afterwards, but grease it a bit before use, then twist it to "tighten" the spring usually works. 3. The difficulty will be getting a smooth curve.

2007年7月6日 · I'm now left with two 1 inch copper pipes (15mm) sticking out of our bathroom wall. The problem I have is the pipes are no longer 'round', either through my removing the old shower or maybe when it was installed they got squashed, either way my new shower will no not fit …

2005年11月16日 · Go to a plumbing merchants and ask for a leadlock, Its a special compression fitting to join lead to copper but you will need to know the size of the lead pipe. This is sometimes hard to tell until you cut the pipe so buy a couple of different size leadlocks if your not certain You can always take back what you don't use and get a refund.
