The DI Double Socket / Flange Taper is a ductile iron fitting designed to transition between two pipe diameters while connecting to flanged components on both ends. The listing confirms it is manufactured from ductile iron to ISO 2531 and AWWA C219 standards, with a socket end on one side and a flanged end on the other. This design allows for both push-fit and bolted connections in water and sewage systems.
The material is specified as ductile iron Grade 400-12 (EN-GJS-400-12), which provides tensile strength of 400 MPa and elongation of 12%. The fitting is designed for pressure applications up to PN16, with wall thicknesses calibrated to maintain structural integrity across diameter transitions. Surface finish is not detailed, but standard practice includes internal cement mortar lining and external bitumen coating for corrosion resistance in buried applications.
This fitting is commonly used in municipal water supply networks, wastewater treatment plants, and industrial process piping where pressure integrity and flow continuity are critical. Buyers in North America, Europe, and Southeast Asia source this product for infrastructure projects. Packaging is container-ready, with bulk shipments typically palletized. Trade terms are not specified, but FOB and CIF are standard. Buyers must confirm dimensional tolerances, pressure ratings, and test documentation before procurement.
| Material | Ductile iron (EN-GJS-400-12 / ASTM A536 Grade 60-40-18) |
| Socket end size range | Typical DN50 to DN1200, with standard socket depth of 1.5x nominal diameter |
| Flange end type | Raised face flange compliant with ISO 7005-2 |
| Flange pressure rating | Standard PN10 or PN16, depending on wall thickness |
| Taper angle | Standard 1:10 taper ratio for smooth transition |
| Wall thickness | Typical 8 mm to 14 mm, based on nominal diameter and pressure class |
| Internal lining | Typical cement mortar lining per ISO 4179 for water contact |
| External coating | Typical bitumen or epoxy coating for corrosion protection |
| Standard compliance | ISO 2531, BS EN545, BS EN598, AWWA C219, AWWA C110, ASME B16.42 |
| Flange bolt hole count | Typical 8 to 16 holes, matching ANSI/ISO flange standards |

Before ordering, verify the taper ratio, socket dimensions, and flange pressure rating against your pipeline design. Confirm the material grade (EN-GJS-400-12) and internal lining type with a mill test certificate. Since the supplier does not respond to inquiries, assume all claims are unverified until confirmed in writing. Do not rely on generic compliance statements - request test reports for each shipment.
Logistics are typically handled via sea freight from Dalian or Tianjin. Lead time is not stated but commonly ranges from 30 to 60 days after deposit. Incoterms like FOB or CIF are standard, but payment terms are not specified. Buyers should negotiate payment via L/C or T/T against inspection certificate, and avoid full prepayment. Packaging must be wooden crate or palletized with moisture barriers to prevent corrosion during transit.
Inspect each fitting for cracks, socket misalignment, or coating defects before installation. Request a sample from each batch for dimensional verification using calipers and a taper gauge. Ensure the supplier provides a packing list with batch numbers and material certification. For critical infrastructure, third-party inspection by SGS or Bureau Veritas is recommended. Retain documentation for traceability in case of field failures.
