水道管や家庭用温水管には、従来より鉄管、真鍮管等の金属製の管材が使用されてきたが、これらの金属製管材の内面は、時間の経過とともに発錆し、生じた錆が飲み水等に混入することが問題となっている。そこで、近年は樹脂を内面にコートした金属管を採用する方法が行われるようになったが、この方法でも金属管の内面の発錆の問題を完全に解決することはできない。このため、最近、給水・給湯配管用に発錆の問題がない合成樹脂製の管を採用する動きが高まっている。Conventionally, metal pipes such as iron pipes and brass pipes have been used for water pipes and domestic hot water pipes, but the inner surface of these metal pipes rusts with the passage of time, and the resulting rust is reduced. There is a problem that it is mixed into drinking water. Therefore, in recent years, a method of using a metal tube coated on the inner surface with a resin has been used, but even this method cannot completely solve the problem of rust on the inner surface of the metal tube. For this reason, recently, there has been an increasing movement to adopt a synthetic resin pipe having no problem of rusting for water supply / hot water supply pipe.
