U‑shape open bolt slots – Bolt holes open to the outer edge; flange can be removed by loosening bolts without full bolt extraction
Fast maintenance – Drastically reduces downtime for cleaning, gasket replacement, or line access – improves plant efficiency
Ideal for confined spaces – Easy operation where bolts cannot be fully pulled out due to limited clearance
Multiple pressure ratings – Customizable from Class 150 to Class 900, suitable for medium and low pressure systems
Full material selection – Carbon steel, stainless steel, alloy steel, duplex, etc., for corrosive, sanitary, or high‑temperature services
Compatible with standard flanges – Bolt circle diameter and slot dimensions can match ASME/EN standard mating flanges and bolts

Socket weld design – Pipe end inserts into the socket, self‑aligning, simple and reliable welding
For high‑pressure duty – Pressure rating up to Class 2500, primarily for NPS 2″ and smaller lines
Smooth bore – Minimal internal weld protrusion reduces turbulence and pressure loss
Wide material choice – Carbon steel, stainless steel, alloy steel for corrosive, high‑temp or low‑temp services
Full standard compliance – Manufactured to ASME B16.11 / ASME B16.5 and GB/T 9116
Multiple facing types – RF, FF, RTJ, MFM, etc. for various gaskets

Weld‑free design – Internal threads (NPT / BSPT / BSPP) machined into the flange; directly screws onto threaded pipe – no welding equipment needed
Ideal for hazardous areas – Perfect for oil fields, chemical plants, gas lines where open flame or hot work is prohibited
Small‑bore, high‑pressure capability – Typically used for NPS 2" and below; pressure rating up to Class 1500
Easy disassembly – Threaded connection allows quick removal for system modification, maintenance or replacement
Full material selection – Carbon steel, stainless steel, alloy steel for corrosive, high‑temp or low‑temp services
Multiple facing types – RF, FF, RTJ, etc.; manufactured to ASME B16.5 / B16.47 or EN 1092‑1

Long tapered hub – Hub thickness gradually transitions to pipe wall, significantly reducing stress concentration at the flange root
Butt weld connection – Flange welded to pipe with beveled ends; weld can be radiographed, strength equals that of base material
Excellent sealing performance – High rigidity, minimal flange rotation under bolting force, ideal for high pressure, high temperature and cyclic conditions
Full‑bore flow path – Flange bore matches pipe I.D. – no turbulence, no dead space, reduces pressure drop and erosion/corrosion
Wide pressure coverage – From Class 150 to Class 2500, sizes NPS 1/2″ up to 48″ and above
Full material & standard range – Carbon steel, stainless steel, alloy steel; ASME B16.5 / B16.47, EN 1092‑1, GB/T 9115, etc.
