Dingxiang Changkai Flanges Trade Co., Ltd. supplies flanges in standard and custom sizes, designed for compatibility with diverse piping systems in oil and gas, construction, and manufacturing. The product range includes weld neck, slip-on, blind, and threaded flanges, manufactured to meet international standards. Dimensions and pressure ratings are aligned with ANSI B16.5, though specific class availability is not listed in the source data.
Flanges are produced from carbon steel, stainless steel, and alloy steel, with common grades including A105, A182 F304, and A182 F316. Surface finishes include mill finish and raised face options, suitable for gasket sealing. The supplier mentions precision engineering for leak prevention, suggesting attention to machining tolerances, but no data is provided on hardness, tensile strength, or heat treatment processes. Material sourcing is not specified beyond general claims of premium quality.
These flanges are typically used in industrial piping where system integrity is critical. Buyers in construction, water treatment, and light manufacturing sectors source them for new installations or maintenance. Trade terms include FOB and CIF, with flexible minimum order quantities based on project needs. Buyers should request documentation confirming compliance with ANSI standards and verify material traceability before acceptance.

Verify the flange material grade and pressure class match your system’s operating conditions. Request material test reports (MTRs) showing chemical composition and mechanical properties. Confirm that the flange face type and finish are compatible with your gasket material. Do not accept flanges without dimensional inspection records, particularly for bolt hole alignment and bore size.
Confirm Incoterms with the supplier - FOB is standard, but CIF may be offered for consolidated shipments. Lead time is typically 30 to 50 days after order confirmation, depending on customization and quantity. Payment terms are commonly 30% advance, 70% against shipping documents. Clarify the port of loading and ensure the supplier provides export documentation including bill of lading and certificate of origin.
Perform pre-shipment inspection focusing on surface finish, dimensional accuracy, and absence of casting or forging defects. Use calipers to verify bolt hole spacing and flange thickness. For stainless steel flanges, check for surface contamination using a chloride test kit. Retain samples for future reference and ensure all documentation matches the purchase order and technical specification.
