A-41 Studies on Stainless Steel Piping System with High Durability : (Part.4) Investigation of Durability of Collect Synthetic Rubbers Used Joints.

Abstract

By this report, a result investigated used synthetic rubber about the factor that let confirmation and deterioration of the deterioration situation go as a sample is shown. 1) The durability of synthetic rubber used for water supply system was around from ten to twenty years. If manufacturer improvers the combination of the synthetic rubber that this, it is hoped that durability becomes longer. 2) The deterioration of synthetic rubber used for a hot water supply system is intense. 3) The antioxidants included in synthetic rubber decrease remarkably in early period of beginning to use. 4) In the synthetic rubber which dose not contact with water, the antioxidants do not decrease.
