Buy & Import Flanges from Dalian Guangming Pipe Fittings Co., Ltd - Wholesale Supply

Dalian Guangming Pipe Fittings Co., Ltd supplies flanges compliant with ANSI B16.5 and ANSI B16.47 standards, covering sizes from 1/4" to 47". These are manufactured in carbon steel and stainless steel, with pressure classes up to Class 2500. The flanges are designed for high-pressure piping systems and include weld neck, slip-on, and blind variants, each machined to precise dimensional tolerances.

Carbon steel flanges are produced from ASTM A105 material, while stainless steel options include 304 and 316 grades, selected for corrosion resistance in chemical environments. The sealing faces are machined to standard raised face profiles with a serrated finish for improved gasket seating. Tolerances for bolt hole alignment and flange thickness follow ANSI B16.5, with no indication of post-weld heat treatment or impact testing performed.

These flanges are primarily used in oil and gas pipelines, refineries, and water treatment plants where system integrity is critical. Buyers include engineering firms, EPC contractors, and maintenance teams sourcing replacement parts. Packaging is in wooden crates with rust inhibitors, and export is handled via Dalian Port. Trade terms offered are FOB and CIF, with lead time estimated at 30 to 45 days. MOQ is not stated but is typically 100 pieces per size.

Frequently Asked Questions About Flanges from Dalian Guangming Pipe Fittings Co., Ltd
Flanges comply with both ANSI B16.5 for sizes up to 24" and ANSI B16.47 Series A for larger diameters from 26" to 47". Buyers must specify which standard applies to their flange size to ensure correct bolt hole pattern and thickness.

Sourcing Flanges from Dalian Guangming Pipe Fittings Co., Ltd - China Import Guide

Verify the flange standard (ANSI B16.5 or B16.47) and pressure class before ordering. Confirm that the material grade matches your service conditions, especially for stainless steel in corrosive environments. Request material test reports (MTR) with chemical analysis and mechanical properties. Do not rely on generic compliance claims without documentation.

Lead time is typically 30 to 45 days, depending on order volume and production backlog. Shipping is usually FOB Dalian Port, with CIF available. Payment terms are commonly 30% advance, 70% against shipping documents. Confirm incoterms, port of discharge, and container type (20ft or 40ft) in writing to avoid delays at destination.

Upon delivery, inspect flanges for surface cracks, correct markings, and dimensional accuracy using calipers and templates. Check for rust prevention coating and packaging integrity. Retain a sample of each size and grade for future reference. Ensure the packing list includes HS code 7307.21 and matches the commercial invoice. Retain all documentation for customs and quality audits.
