Class 1500 Blind Flat Face Flange Dimension
The Class 1500 Blind Flat Face Flange is a forged pipe end closure designed to seal off pipeline sections under high pressure. It is manufactured from ASTM A105 carbon steel or ASTM A182 F316 stainless steel, conforming to ASME B16.5 dimensional standards. The flat face design allows full-face gasket contact, making it suitable for low-pressure sealing applications where alignment is critical.
Forging ensures superior mechanical properties over casting, with better grain flow and impact resistance. The flange’s thickness and bolt hole pattern are determined by the nominal pipe size and pressure class. Typical bolt sizes range from 3/4 inch to 2 inches depending on diameter. The surface finish on the sealing face is typically 125 to 250 microinch Ra to ensure proper gasket compression without damage.
These flanges are used in oil and gas pipelines, petrochemical plants, and power generation systems for isolating equipment or terminating lines. Buyers include pipeline contractors, maintenance teams, and engineering procurement firms. Packaging is in wooden crates with anti-rust paper and plastic wrap. Trade terms are usually FOB Tianjin or Qingdao. Minimum order quantities are not stated and must be confirmed directly with the supplier.

Sourcing Class 1500 Blind Flat Face Flange from Langfang Dingyang Flange Pipe Fitting Co., Ltd. - China Import Guide
Before ordering, verify the material test reports for both body and bolt holes against ASTM A105 or A182 F316. Request a dimensional inspection report against ASME B16.5, especially for bolt circle diameter and flange thickness. Confirm that the flange is marked with the pressure class, material grade, and manufacturer’s name per ASME standards.
Confirm the Incoterms - FOB Tianjin is common, but CIF may be offered. Lead times are typically 4 to 6 weeks after order confirmation. Payment terms are often 30% advance and 70% against copy of shipping documents. Clarify whether the price includes export documentation, port handling, and insurance.
Inspect flanges upon arrival for surface cracks, correct markings, and proper packaging. Check the flange thickness and bolt hole alignment with a caliper and template. Verify the material grade matches the MTR. Retain packaging and documentation for at least 12 months. For critical systems, consider third-party inspection before installation.
