The flanged face incorporates precision concentric sealing grooves that grip full-face EPDM elastomeric gaskets, preventing gasket extrusion and guaranteeing leak-tight hydrostatic performance up to 16 Bar water pressure under heavy hydraulic thrust forces.\n\nThe companion backing rings are manufactured from high-tensile ductile iron (EN-GJS-450-10) or structural carbon steel (ASTM A105 / S235JR) with hot-dip galvanized or fusion-bonded epoxy protective coatings (minimum 250 microns). Drilled strictly to international flange standards including EN 1092-2 (PN10, PN16, PN25) and ANSI B16.5 Class 150, the backing ring bore features a radius chamfer that seats uniformly against the HDPE stub shoulder, distributing bolt clamping forces evenly without localized stress concentrations.\n\nIn severe Iraqi soil environments, where subsoil moisture and high salt concentrations attack metallic infrastructure, the fusion-bonded epoxy coating protects the backing rings against electrochemical corrosion.

Governed by ISO 4427-3, EN 12201-3, and DIN 16963 standards, these stub ends are molded from virgin PE100 resin. The flanged face incorporates precision concentric sealing grooves that grip full-face EPDM elastomeric gaskets, preventing gasket extrusion and guaranteeing leak-tight hydrostatic performance up to 16 Bar water pressure under heavy hydraulic thrust forces.\n\nThe companion backing rings are manufactured from high-tensile ductile iron (EN-GJS-450-10) or structural carbon steel (ASTM A105 / S235JR) with hot-dip galvanized or fusion-bonded epoxy protective coatings (minimum 250 microns). Drilled strictly to international flange standards including EN 1092-2 (PN10, PN16, PN25) and ANSI B16.5 Class 150, the backing ring bore features a radius chamfer that seats uniformly against the HDPE stub shoulder, distributing bolt clamping forces evenly without localized stress concentrations.\n\nIn severe Iraqi soil environments, where subsoil moisture and high salt concentrations attack metallic infrastructure, the fusion-bonded epoxy coating protects the backing rings against electrochemical corrosion. Staged in our Erbil Heavy Plant Yard, Baghdad Central Logistics Depot, and Basra Port Hub, Indus supplies complete flanged transition packages including high-tensile hot-dip galvanized Grade 8.8 bolts, nuts, and steel-reinforced EPDM gaskets.", "image": [ "https://indusiraq.com/assets/images/indus_logo.png" ], "datePublished": "2026-09-11T22:40:48+03:00", "dateModified": "2026-11-08T02:35:55+03:00", "author": { "@type": "Organization", "@id": "https://indusiraq.com/division/water-wastewater#directorate", "name": "Indus Division 01: Water & Wastewater Engineering Directorate" }, "publisher": { "@type": "Corporation", "@id": "https://indusiraq.com/#corporation", "name": "Indus Industrial Group - Iraq", "logo": { "@type": "ImageObject", "url": "https://indusiraq.com/assets/images/indus_logo.png" } }, "inLanguage": "en", "about": { "@id": "https://indusiraq.com/product/hdpe-flange-adaptors-stub-ends-dn50-dn1200#product" } }, { "@type": "FAQPage", "@id": "https://indusiraq.com/product/hdpe-flange-adaptors-stub-ends-dn50-dn1200#faq", "mainEntity": [ { "@type": "Question", "name": "What is the correct bolt torque procedure for HDPE stub ends in Iraq?", "acceptedAnswer": { "@type": "Answer", "text": "HDPE stub ends require cross-pattern torque tightening in incremental steps (30%, 60%, 100%) using a calibrated torque wrench.
