Designed for butt welding pipe connections with superior structural strength, capable of withstanding high temperature and pressure conditions. Features reliable sealing performance with concave-convex sealing surfaces for nominal pressures of 0.25-2.5Mpa.
Suitable for carbon steel pipe connections up to 2.5Mpa nominal pressure. Available in smooth, concave-convex, and tongue-groove sealing surfaces. Cost-effective solution for mild service conditions.
Commonly used in pipelines with PN≤10.0Mpa and DN≤40 diameters.
Ideal for corrosive media applications where the flange contact area uses corrosion-resistant materials while the outer ring utilizes cost-effective carbon steel.
