High Temperature resistant fire sleeve widely serves in petrochemical industry
In our daily life, we will use various kinds of hoses. While most of them are plastic hose and rubber hose. In some cases, we use them to transfer water. Some rubber hose is ideal for water transfer. But is plastic hose suitable for water? In fact, whether plastic is safe or not depends on many factors.
First, material type
Different types of plastic water pipes have different safety. For example, PVC water pipe is safe if it is fully polymerized and contain no harmful additives. However, it may degrade and produce harmful substances under high temp or long-term UV. The PPR water pipe itself is non-toxic. But it lacks self-cleaning function. Long-term use may cause bacteria to grow on the inner wall. Then it will affect the water quality.
Production quality
Plastic water pipes produced by regular manufacturers should comply with national and international quality standards. Make sure the material is pure and free of impurities. And no chemicals such as toxic plasticizers are added during the production process.
Conditions of Use
Different plastic pipes are suitable for various temp and pressure conditions. Normal temp water pipes such as PE and PB are safe under common conditions. When used for hot water pipes, you should choose a material with good heat resistance. Otherwise, harmful substances may precipitate at high temp.
Maintenance
After a long time, the plastic hose may age or get damaged. Thus properly maintain and regularly replace can reduce the risk of water pollution.
In a word, a qualified plastic water pipes is safe under normal use. However, for hot water supply, you need a hose which is more stable and durable. What’s more, it should not release harmful substances. Such as stainless steel hose or other advanced composite materials.
