Class 300 6in Swivel Flanges RTJ

Swivel flanges are becoming more and more popular now, it includes a heavy forged welding hub and a rotating Forged Ring that serves as a mating flange to a Weld Neck.These versatile flanges are utilized in many applications and are used extensively in offshore piping where they solve the issues associated with the alignment of bolt holes during subsea flange installation.

The pressure-temperature ratings and basic dimensions in Class 150 through Class 2500, are identical to ASME/ANSI B16.5 and MSS-SP44 Flanges and will readily mate to a standard Weld Neck Flange .

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.

About Our Company:
