Ductile Iron pipes IS 8329

About Ductile Iron pipes IS 8329

S 8329 is the Indian Standard specification by the Bureau of Indian Standards (BIS) for centrifugally cast (spun) ductile iron pressure pipes used for water, gas, and sewage. These pipes feature high tensile strength, impact resistance, and corrosion protection, spanning nominal diameters from 80 mm to 2000 mm in pressure classes like K7, K9

Core Specifications & Classes

• Standard Scope: Covers buried and above-ground pipelines carrying pressurized fluids or gases.
• Material Composition: Utilizes spheroidal graphite/ductile iron meeting strict mechanical elongation and tensile criteria.
• Wall Thickness Classes: Commonly produced in K7, K9, and K12 wall thickness grades depending on structural and pressure demands.
• Coatings & Linings: Features external zinc coatings with finishing layers and internal cement mortar linings for longevity.
• Regulatory Compliance: Mandatory ISI certification applies to all manufacturers producing these items for the Indian market.
