Di Pipe Fittings, Double Flanged Bend.
Double flanged bend fittings made from ductile iron (DI), also known as spheroidal graphite iron (SGI), are engineered for high-pressure fluid transport in municipal and industrial systems. These fittings from Jilin Senfeng Pipe Co., Ltd. comply with ISO 2531, BS EN545, BS EN598, AWWA C110, and ASME B16.42 standards, ensuring structural integrity under dynamic loads. The material grade is either 400-15 or 500-7, providing tensile strength of at least 400 MPa and elongation of 15% or more, critical for resisting brittle fracture in buried applications.
Internal linings include cement mortar, sulphuric resistance cement, or a combination with epoxy, chosen based on the aggressiveness of the conveyed medium. External coatings range from zinc and bitumen to metallic zinc with dual epoxy layers, offering corrosion resistance in soils with high chloride or sulphate content. These are not generic fittings; they are manufactured to withstand operating temperatures from -40°C to 125°C, making them suitable for both cold climate water networks and industrial steam systems. Packaging is plastic film over wooden pallets, designed for sea freight and repeated handling without damage.
These fittings are primarily purchased by civil engineering contractors, municipal water authorities, and industrial plant operators in regions with aging infrastructure or expanding sewage systems. Buyers require certified compliance with international standards and consistent dimensional tolerances for flange alignment. Trade terms are typically FOB Qingdao or CIF destination, with minimum order quantities negotiated per project volume. Lead times are generally 30 to 45 days after deposit, depending on production scheduling and coating curing cycles.

Double Flanged Bend fittings manufactured from high-strength ductile iron are critical components in water transmission, sewage, and irrigation pipeline systems. Compliant with ISO 2531, BS EN545, BS EN598, AWWA C110, and ASME B16.42 standards, these fittings feature internal cement mortar or sulphuric resistance cement lining for enhanced corrosion protection in aggressive soil and water conditions. Widely sourced from global DI pipe fitting exporters, they are essential for municipal infrastructure, industrial water networks, and fire protection systems requiring reliable flanged connections at directional changes.

Sourcing Di Pipe Fittings, Double Flanged Bend from Jilin Senfeng Pipe Co., Ltd. - China Import Guide
Before placing an order, verify the material grade (400-15 or 500-7) with a certified test report for tensile strength and elongation. Confirm the internal lining type matches the fluid medium - sulphuric resistance cement for acidic or saline conditions, standard mortar for potable water. Request a coating thickness report and ensure it meets the specified layers, especially if the pipeline runs through corrosive soils. Do not accept generic compliance statements without batch-specific documentation.
Confirm Incoterms with the supplier: FOB Qingdao is standard, but CIF terms may be negotiable. Lead time typically ranges from 30 to 45 days, depending on coating curing cycles and production backlog. Payment is usually 30% deposit with balance against shipping documents. Ensure the packing list matches the pallet count and that each pallet is labeled with product ID, batch number, and coating type. Request a container loading inspection if shipping large volumes.
Conduct a pre-shipment inspection focusing on flange face flatness, bolt hole alignment, and lining integrity. Use a profilometer to check internal roughness if the system is sensitive to flow loss. Verify the external coating has no cracks or blistering, especially at weld seams. Request copies of the material test reports, coating adhesion tests, and hydrostatic pressure test records. Ensure the supplier provides a certificate of conformity matching each shipment, referencing the applicable standards and batch numbers.
