Black painting flange looks more seriously than other colors, it is needed in the markets of south east and mild east of Asia.

Slip on weld fange can be slid onto a pipe and then welded in place. It is made of carbon steel, alloy steel, and stainless steel. 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.  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.
