ASME Flange B16.5 Flange Threaded Flanges are also known as screwed flange, have a thread inside the flange bore which fits on the pipe to match male thread on the pipe.
This type of joint connection is Speedy and simple but not suitable for high presser and temperature applications. Threaded Flanges are mostly used in utility services such as air and water.
Threaded (Screwed) flange is similar to the Slip-On flange, but the bore is threaded. it can be assembled withour welding.
The industrial processes come into die forging,and machining,we can provide a wide range of BS4504 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. BS4504 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.
