The Flange Socket for UPVC Pipe is a ductile iron fitting designed to create a secure mechanical connection between UPVC pipelines and flanged equipment such as valves, pumps, and meters. Manufactured from GJS-400-15 or GJS-450-10 ductile iron, it meets BSEN545 and ISO2531 standards for pressure-rated pipe systems. The socket end is internally molded to accept standard UPVC pipe diameters, while the flange face is drilled for bolted attachment.
Ductile iron in this application provides superior tensile strength and impact resistance compared to gray iron, making it suitable for buried and high-pressure water systems. The GJS-400-15 grade offers a minimum tensile strength of 400 MPa and 15% elongation, while GJS-450-10 provides higher strength for demanding applications. The internal socket is typically lined with a rubber gasket to ensure a watertight seal with UPVC pipe, though the listing does not specify gasket material.
This fitting is widely used in municipal water distribution, agricultural irrigation, and industrial fluid transfer systems across Asia, Africa, and Latin America. Buyers typically source it for infrastructure projects requiring durable, corrosion-resistant connections. Packaging is in bulk cartons or wooden crates, with standard export packaging. Incoterms are not listed, but FOB Qingdao is common for this supplier.

Before ordering, verify the exact socket diameter matches your UPVC pipe's outer diameter and that the flange bolt pattern aligns with your valves or pumps. Request a material test report confirming GJS-400-15 or GJS-450-10 grade and tensile elongation values. Confirm the gasket material is suitable for your fluid type and temperature range, as this is not stated in the listing.
Lead time is not specified but typically ranges from 25 to 45 days for bulk orders from China. Incoterms are likely FOB Qingdao or CIF destination port. Payment terms are commonly 30% advance, 70% against BL copy. Confirm whether the supplier handles export documentation, including COO and compliance certificates. Request a sample shipment to assess packaging and transit protection.
Perform dimensional checks on received batches using calipers and gauges. Test hydrostatic pressure on sample fittings per ISO2531 Annex C. Inspect the flange face for machining defects and verify coating integrity if specified. Ensure all documentation includes batch numbers for traceability. For critical infrastructure, consider third-party inspection at origin before shipment.
