Stainless Steel Blind Flanges<\/h1>\t\t\t\t<\/div>\n\t\t\t\t

As a specialist manufacturer<\/b>, Sunhy engineers high-integrity stainless steel blind flanges<\/a><\/b> for the critical, high-stress task of sealing and isolating<\/b> piping systems.<\/p>

Unlike flanges designed for flow, a blind flange is a solid, non-bored disc that must safely absorb the full internal pressure<\/b> of a line (acting as a high-stress mechanical seal). Our flanges are forged from premium SS316L<\/b> and SS304L<\/b> (per ASTM A182<\/b>) to provide absolute containment in high-pressure, corrosive, or hygienic applications.<\/p>

We manufacture to all relevant standards, including ASME B16.5<\/b> (up to 24″) and ASME B16.47<\/b> (for large diameters), ensuring every flange is delivered with a full EN 10204 3.1 MTR<\/b> for guaranteed compliance and traceability.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
