1. Polybutylene pipes. Compared with other polymers polybutylene more elastic and thermal conductivity, can withstand temperatures up to 90oS transported fluid, in connection with what is used for mounting “warm floor.” It is easy curling, transported to the bays. Connection welding.
2. Tubes made of polyethylene. Durable. Stretch. A good insulator. Distinguish polyethylene of high and low density. High density polyethylene is stronger, but less elastic. Suitable for cold water. Ideal for installation of water gardening, because, due to its flexibility, tolerates freezing water without damage to the pipeline. Connection welding. In Europe, most used the PEX plumbing tubing from the so-called “cross-linked” polyethylene (PEX). Suitable for hot and cold water and heating. Connection disassembled fittings and crimping.
3. Pipes made of polyvinyl chloride (PVC). Of all the polymers more rigid. Resistant to ultraviolet rays, aggressive chemical compounds. Small proportion. Low flammability. The bad news – the presence of chlorine in the compound. Connected by gluing.
4. Pipes made of polypropylene. Depending on the label used for hot and cold water, heating and sanitation. Physico-chemical and thermal properties of polypropylenes are close to the sewn polyethylene, but unlike the latter is cheaper and easier to install. Connection welding.
Thus, for the American “average” consumer who wants to do self-assembly, and to focus on price / quality ratio, the most appropriate choice – a tube of polypropylene or polyvinyl chloride.
