Pipes of Tweetop system are produced using PERT - polyethylene with elevated temperature properties. To put it very simply, the structure of this material is similar to balls of wool which are merged mutually with side threads, resulting in a structure that is very tangled but very strong and difficult to break. When it comes to pipes, this translates into high resistance to temperature and pressure, which is so important in plumbing and heating systems.
In our company laboratory, right now most advanced and well-equipped facility of this kind in Poland, we are able to thoroughly check raw materials, fittings and pipes manufactured by us. We conduct all test according to the newest norms and recommended by technical approvals we held (including PN_EN_ISO_21003 norm). Some of the most important tests we conduct:
