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.
Key Features: ASME B16.5/EN 1092-1 certified | Carbon steel/Stainless steel/Duplex options | High-pressure sealing performance
Common Uses: Oil & gas storage tanks | Water treatment systems | Industrial equipment inspection ports
SO flanges offer quick installation and budget-friendly performance for low-to-medium pressure pipelines.
Key Features: Dual-welded design for stability | Easy pipe alignment | Reduced labor costs
Common Uses: HVAC systems | Food-grade piping | Low-pressure steam lines
Engineered for high-temperature and high-pressure environments, weld neck flanges ensure superior stress distribution and durability.
Key Features: Tapered hub welding technology | Fatigue-resistant design | API 6A/ASME B16.25 compliance
Common Uses: Subsea oil pipelines | Power plant boilers | Chemical processing reactors
✅ Global Certifications: ISO 9001, PED 2014/68/EU, and API Q1 compliant
✅ Custom Solutions: Tailored dimensions, materials (Inconel, Titanium), and face types (RF, FF, RTJ)
✅ Fast Shipping: 20,000+ in-stock flanges | 48-hour expedited delivery for urgent orders
