Type11 Welding Necking PN10, PN16, PN25, PN40 S235 Carbon Steel Flanges

DIN FLANGE Size range: DN15 to DN2000 Design: slip on flange DIN2573,2576,2502,2503, 2543,2545 welding neck falnge DIN2631, 2632,2633,2634,2635 blind flange DIN 2527 PN6, PN10, PN16, PN25, PN40 threaded falnge DIN2565,2566,2567,2567 loose flange DIN 2641,2642,2656,2673 Material: Carbon steel ST37.2/S235JR,C22.8. Stainless steel 1.4301, 1.4404

Size range: 1/2" to 80" DN15 to DN2000 Design: welding neck, slip on, blind, socket welding, threaded, lap-joint Pressure: 150#, 300#, 600#,900#,1500#, 2500# Wall thickness for welding neck flange: STD, SCH40, SCH80, SCH160. SCHXXS Material: Carbon steel A105, Stainless steel 304/304L, 316/316L Coating: black paint, yellow transparent paint, cold and hot dip galvanize Forging process is more expensive than the cast iron process Casting iron can be manufactured to fit different complex profiles Forging process doesn't lead to the manufacture of big or uneven brain Cast iron flange is used exclusively for non-pressure pipelines, while forged Steel Flange is used in higher pressure pipeline

The centrifugal machine is used to manufacture high precision cast iron flange than standard cast flanges Forged Steel can easily be cut, and it can withstand higher tensile strength Overall, forged steel is better than cast iron flanges in terms of performance as it comes with a better shape and also much lower carbon content which leads to less rusting.ANSI B16.5, ASME B16.5/B16.47 FLANGESize range: 1/2" to 80" DN15 to DN2000 Design: welding neck, slip on, blind, socket welding, threaded, lap-joint Pressure: 150#, 300#, 600#,900#,1500#, 2500# Wall thickness for welding neck flange: STD, SCH40, SCH80, SCH160.
