BL Flange
SDFL
Stainless steel blind flange is an indispensable key component in oil and gas pipeline systems. Oil and gas transportation pipelines are usually in high-pressure, variable temperature and slightly corrosive working conditions, which require pipe fittings with high structural strength and stable sealing performance. Forged stainless steel blind flanges feature dense metal structure, excellent pressure resistance and impact resistance. They are widely used for temporary pipeline closure, branch port blocking, and isolation of idle pipeline sections in oilfield gathering pipelines, natural gas transmission pipelines and refinery process pipelines. Different from ordinary carbon steel blind flanges, 304 and 316L stainless steel materials effectively resist hydrocarbon corrosion and atmospheric oxidation, avoiding flange rusting, deformation and medium leakage during long-term service. All our stainless steel blind flanges are 100% hydrostatic pressure tested, fully compliant with ASME B16.5 industry standards, and perfectly adapt to long-term stable operation of high-pressure oil and gas engineering projects.
