一般社団法人日本ダクタイル鉄管協会 List of Products and Services

The Japan Ductile Iron Pipe Association, a general incorporated association, handles the "GX type ductile iron pipe," which achieves an ultra-long lifespan of pipelines by adopting an external corrosion-resistant coating that dramatically enhances corrosion protection through traditional synthetic resin painting. By improving the existing joint structure, it enables connections with a narrower excavation width compared to the conventional NS type joints. Additionally, it offers advantages that can reduce overall construction costs compared to NS type joints, achieving pipeline installation costs comparable to K type. 【Features】 ■ Reduction in pipeline installation costs ■ External corrosion-resistant coating that enables ultra-long lifespan ■ Improved workability makes it easier to construct earthquake-resistant pipelines *For more details, please download the PDF or feel free to contact us.
