High Light 4 inch alloy steel blind flangeDN150 ASME B16.5 flangeA182 F91 blind flange

4 Inch DN150 A182 F91 Alloy Steel Blind Flange ASME B16.5 Standard

 

This blind flange is a premium industrial pipeline fitting, strictly manufactured in accordance with ASME B16.5 standard, made of high-performance A182 F91 alloy steel, with specifications of DN150 and 4 inches. It is specially designed to seal the end of pipelines, effectively preventing fluid leakage and ensuring the safe, stable operation of industrial pipeline systems.
 
A182 F91 alloy steel is a high-chromium-molybdenum alloy steel, featuring excellent high-temperature strength, creep resistance and corrosion resistance, which can withstand long-term operation under high temperature and high pressure conditions—ideal for harsh industrial environments. The blind flange is processed by precision forging and machining, with a smooth sealing surface, precise dimensional accuracy and compact structure, ensuring tight fit with pipeline ends and reliable sealing performance. It is easy to install and disassemble, facilitating pipeline maintenance, inspection and later modification.
 
Widely applied in petroleum refining, chemical industry, power plants, boilers, heat exchangers and other high-temperature, high-pressure pipeline systems, suitable for both temporary and permanent pipeline end sealing. Strict quality inspection (including material composition analysis, pressure testing, dimensional detection and surface quality inspection) ensures full compliance with ASME B16.5 standards and international industrial requirements. With outstanding durability, good interchangeability and stable performance, it provides a cost-effective and reliable sealing solution for industrial pipeline projects.
