ASTM A350 LF2 is the most common and popular material in our daily flange production, besides this one, A350 LF3 and A350 LF6 is also used for forged flanges, we can produce them all, any need, pls contact.

The below photo is A350 LF6 API 6B 10000psi WNRTJ flanges in plywood packing for delivery.

The industrial processes come into die forging,and machining,we can provide a wide range of slip on weld 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. Slip on flange is a type of flange that extends steel pipes, pipe fittings, etc into the flange and connects with equipment or pipelines through fillet welds. This flanges have short neck, which increases the strength of the flange and improves the bearing capacity of the flange. So it can be used on higher pressure pipelines.

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.
