SYSTEMS
K7 DUCTILE IRON PIPE
Supra's K7 blog positions K7 ductile iron pipe as a strong solution for water supply, sewage and industrial pipeline
applications. It discusses strength, impact resistance, corrosion protection and flexible jointing. The blog states that
K7 can typically resist internal pressure up to 16 bar; final selection must follow the applicable standard and project
design.
Parameter K7 K9
IS:8329 class K7 K9
DN100 thickness example 5.0 mm 6.0 mm
DN600 thickness example 7.7 mm 9.9 mm
DN1000 thickness example 12.0 mm 13.5 mm
Selection principle Use when design/specification permits Use where design/specification calls for K9
DOUBLE-FLANGE / FLANGED PIPE
The specified double-flange blog explains the value of flange connections and puddle arrangements where a pipe
penetrates walls, slabs or other structures. The flanged-pipe page describes gasketed flange connections and
applications such as pump houses, treatment plants, vertical and exposed installations.
