Long Welding Neck

Welding neck flange are distinguished from other types by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe. The long tapered hub provides an important reinforcement of the flange proper from the standpoint of strength and resistance to dishing.
The Welding Neck Flanges are normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange. The welding neck flange is the best designed butt-welded flange of those currently avaliable because of its inherent structural value. It is expensive because of the design.
The industrial processes come into die forging,and machining,we can provide a wide range of flanges,following on standards like ASME B16.5 Flange , ASME B16.47 Flange, DIN 2573 Slip On Flange, DIN 2631 Welding Neck flange, JIS Flange 5K SOP Flange and JIS Flange 10K SOH Flange.

ASME Flange include ASME B16.5 Flange, ASME B16.47-A Flange, ASME B16.47-B Flange, this standard system include slip on flange, blind flange, welded neck flange, Threaded Flange, lapped joint flange (loose flange), socket welded flange, B16.36 Orifice Flange, long Weld Neck Flange and Special Flange, sizes from 1/2 inch to 60 inch, class 150, class 300, class 600, class 900, class 1500, class 2500.
