Sand Casting Flange, Connecting Cage & Flange
The Sand Casting Flange, Connecting Cage & Flange assembly is a cast iron component designed for high‑pressure industrial piping systems. It is offered by Qingdao World Wide Machinery Co., Ltd. and produced from Ductile Iron GGG 50, which conforms to the EN‑GJS‑500‑7 standard. The assembly integrates a flange with a connecting cage, allowing secure attachment to pipe sections and facilitating alignment in complex pipelines. The casting process uses green sand moulds to capture the intricate geometry required for fluid transport applications.
GGG 50 ductile iron provides a tensile strength of approximately 500 MPa and excellent impact resistance, typical for pipe fittings that must endure cyclic loading. The material’s nodular graphite structure reduces brittleness compared to gray iron, a standard advantage in water treatment, oil and gas, and chemical processing plants. In the casting industry, such flanges are commonly supplied in standard pressure classes PN10‑PN40, with typical dimensions ranging from 150 mm to 600 mm nominal diameter. Surface finish after green‑sand casting usually meets a roughness of Ra 1.6‑3.2 µm, suitable for subsequent machining or coating.
Primary customers include pipeline manufacturers, plant engineers and maintenance contractors needing reliable junctions for high‑capacity systems. The supplier indicates that the product can be fabricated to client‑provided drawings, allowing custom bolt patterns or flange rating adjustments. Trade conditions such as MOQ, packaging size and Incoterms are not listed and should be confirmed directly with Qingdao World Wide Machinery. Prospective buyers are encouraged to request a material test certificate and dimensional inspection report before finalising the purchase.

Sourcing Sand Casting Flange, Connecting Cage & Flange from Qingdao World Wide Machinery Co., Ltd. - China Import Guide
Importers should first confirm the exact flange dimensions, pressure rating and bolt hole pattern required for their pipeline. Request the supplier’s latest casting drawing and a material test certificate that verifies compliance with EN‑GJS‑500‑7. It is also advisable to obtain a dimensional inspection report confirming the nominal diameter and wall thickness before finalising the order.
Shipping is normally arranged in heavy‑duty wooden crates or on steel pallets, suitable for handling by sea freight forwarders. Buyers need to agree on the Incoterm - FOB Qingdao is common - and clarify the expected lead time after drawing approval. Payment terms are typically negotiated on a TT or L/C basis, and a pro‑forma invoice should detail these conditions.
A third‑party factory audit or pre‑shipment inspection is recommended to check casting integrity, surface finish and dimensional accuracy. Ensure the inspection includes hardness testing and verification of the pressure class marking on the flange. Upon receipt, conduct a receiving inspection to compare the part against the approved specifications and accompanying certificates.
