How to choose ductile iron pipe

1. The selection of ductile iron pipes should be based on the specific conditions of the installation site, and the interface between the straight pipe and the pipe fittings should be selected. 2. The rubber ring is usually made of NBR, SBR, EPDM and other materials. 3. The choice of coating: Choose a suitable coating according to the internal and external conditions during use. The existing internal coatings include epoxy resin, polyurethane internal and external coatings, PE film coatings and other new products of ductile iron pipes. The performance should be understood in detail when choosing. 4. Theoretical weight table of ductile iron management: nominal diameter DN (mm), outer diameter DE (mm), wall thickness T (mm), approximate weight of the socket convex (kg). Weight per meter (kg) and total mass (kg) of the linear part (standard working length 6000mm). Total weight (kg) (standard working length 5000 mm).
