Frequently Asked Questions About Flange from Dingxiang Changkai Flanges Trade Co., Ltd.
The bolt circle diameter tolerance is ±1.6 mm for sizes up to 24 inches under ANSI B16.5. This ensures alignment with mating flanges and prevents uneven gasket loading. Buyers should request dimensional inspection reports, especially for large-diameter flanges used in critical systems.

Sourcing Flange from Dingxiang Changkai Flanges Trade Co., Ltd. - China Import Guide

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.
