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.
