So far the best material for PEX tubing in the world recognized as “cross-linked” polyethylene (PEX). However, the material on roads, our sales network is not available, and installation of water, due to some complexities are best left to professionals.
The material of choice for domestic handmade now – it polypropylene-Rand (Type 3) and PVC. How do they differ? PVC pipes more “hard”, ie less elastic than polypropylene, so their installation in the open more aesthetic (not to be “curves” pipe), the more they are less afraid of sunlight. Bonding in hard to reach places easier than welding (PVC connected to the adhesive, and polypropylene welded special apparatus). However, unlike polypropylene, PVC pipes expensive. Fittings of metal usually PVC, which requires caution when installing. For the same reason, the radiator PVC pipes must be connected through metal reducers. A variety of fittings, combination of threaded adapters “on metal”, valves and fittings for polypropylene pipes produced much more than for PVC. Price welding machine for polypropylene – from 100 to 300 $.
The second lesson will focus on ways to connect plastic pipes. The author would be grateful for any comments and additions on the article.
