Title (EN) ANT NEST CORROSION-RESISTANT COPPER PIPE
(FR) TUBE DE CUIVRE RÉSISTANT À LA CORROSION DE TYPE FOURMILIÈRE
(JA) 耐蟻の巣状腐食性銅管
Abstract:
(EN) The purpose of the present invention is to provide a copper pipe, which is capable of exhibiting higher corrosion resistance to ant nest corrosion over long periods, can be used suitably as heat transfer pipes, coolant piping, etc. in air conditioning equipment and refrigeration equipment and has excellent anti-corrosion properties, and to advantageously improve the service life of equipment configured using said copper pipe. The present invention uses a copper pipe made from a Cu alloy containing P (phosphorus) in a proportion of 0.15-0.50 mass% and containing elemental Ti (titanium) and/or Sb (antimony) in a total amount of 0.01-3.0 mass%.
(FR) La présente invention concerne un tube de cuivre, qui est apte à présenter une résistance supérieure à la corrosion de type fourmilière sur de longues périodes, peut être utilisé de façon appropriée en tant que tube de transfert de chaleur, tuyauterie de fluide de refroidissement, etc. dans un équipement de climatisation et un équipement de réfrigération et présente d'excellentes propriétés anti-corrosion. Ainsi l'invention permet d'améliorer avantageusement la durée de vie d'un équipement configuré à l'aide dudit tube de cuivre. Plus précisément, l'invention met en œuvre un tube de cuivre constitué d'un alliage de Cu contenant du P (phosphore) dans une proportion de 0,15 à 0,50 % en masse et contenant du Ti élémentaire (titane) et/ou du Sb (antimoine) dans une quantité totale de 0,01 à 3,0 % en masse.
(JA) 蟻の巣状腐食に対して、より一層高い耐食性を長期間に亘って発揮することが出来る、空調機器や冷凍機器における伝熱管や冷媒配管等として好適に用いられ得る、防食性に優れた銅管を提供し、また、そのような銅管を用いて構成される機器の寿命を有利に向上せしめること。 P(りん)を0.15~0.50質量%の割合で含有すると共に、Ti(チタン)及びSb(アンチモン)のうちの少なくとも何れか一つの元素を、合計量で、0.01~3.0質量%含有するCu合金からなる銅管を用いることとした。
