Industrial Flange Solutions: Comprehensive Guide to Blind Flanges, SO Flanges & Weld Neck Flanges
Selecting the right flange is critical for pipeline system safety and efficiency. This guide explores three essential flange types—Blind Flanges, SO Flanges (Slip-On Flanges), and Weld Neck Flanges—detailing their technical specifications, applications, and industry standards to help you optimize your projects.
Blind flanges are designed to seal pipe ends permanently or temporarily, ideal for pressure testing, maintenance isolation, or future system expansion.
