Product Advantages
Standard Compliance & High Reliability
Manufactured per ASME B16.5, the blind flange ensures precise dimensions, stable mechanical properties, and zero-leakage closure, meeting the strict sealing and pressure resistance requirements of diverse industrial scenarios.
Diverse Material Options
The blind flange offers rich material selections (carbon steel, stainless steel, alloy steel) to adapt to various media (oil, gas, water, steam, corrosive liquids) and harsh working conditions (high temperature, high pressure, corrosion).
Superior Processing & Durability
The forged blind flange features higher density, strength, and toughness than cast alternatives, enabling long-term, reliable operation in harsh industrial environments.
Main Applications
Petroleum & Natural Gas
The blind flange seals and isolates wellhead, gathering, compressor, and valve station pipelines, ensuring high-pressure oil and gas system safety.
01
Chemical & Power
The blind flange isolates reactors, heat exchangers, and boilers, enabling safe maintenance of high-temperature, corrosive pipelines.
02
Shipbuilding & Marine
The blind flange resists seawater corrosion in ballast, fuel, and fire systems, securing marine pipeline operations.
03
Municipal & Civil
The blind flange isolates water, heating, gas, and fire pipelines for maintenance, supporting stable public facility operation.
