These expansion joint flanges are manufactured from stainless steel, specifically designed to accommodate thermal expansion and vibration in pipeline systems. The flanges feature customizable mounting options, allowing for fixed or loose configurations depending on system requirements. Dimensions and bolt patterns are adaptable to meet ANSI and EN standards, though exact sizes must be confirmed with the supplier.
The material is typically austenitic stainless steel, such as 304 or 316 grade, offering corrosion resistance in humid, chemical, or saline environments. These grades are standard in industrial piping where exposure to moisture or mild acids occurs. The expansion joint component is integrated to absorb axial, lateral, and angular movement, reducing stress transfer to connected equipment.
End users include oil and gas facilities, water treatment plants, and industrial HVAC systems where pipeline integrity under thermal cycling is critical. The product is supplied in bulk quantities with standard packaging in wooden crates or palletized units. Trade terms are negotiable, but lead time and incoterms must be confirmed directly with the supplier before order placement.

Before ordering, verify the exact stainless steel grade, pressure rating, and dimensional tolerances against your piping system. Request material certification (EN 10204 3.1 or equivalent) to confirm composition and mechanical properties. Ensure the flange design matches your pipeline’s expansion requirements, particularly if operating under cyclic thermal loads.
Confirm incoterms, lead time, and payment terms directly with the supplier. Standard shipping is FOB Ningbo or Shanghai, but CIF and DAP are negotiable. Lead time is typically 4 to 6 weeks after order confirmation, though stock availability may vary. Packaging must be specified to prevent corrosion during ocean transit.
Inspection should include visual checks for surface defects, dimensional verification with calipers, and pressure test documentation. Request a copy of the hydrostatic test report and material traceability records. For critical applications, consider third-party inspection at the factory before shipment to ensure compliance with your engineering specifications.
