Threaded flanges are threaded in the bore to match an external thread on the pipe. The threads are tapered to create a seal between the flange and pipe as the tapers approach the same diameter. These flanges are normally designed for low pressure, non-cyclic applications.
Cangzhou Hangsheng Flange & Pipeline Equipment Co.,Ltd has been a international manufacturer of flanges and precision machining in carbon steel, stainless steel and the alloys since 2002. We also manufacture DIN/JIS/BS (Metric) flanges, orifice unions, galvanized flanges, long weld necks, pad flanges / studding outlets, special facings and custom flanges.
Orifice flanges may be provided in one of three types of flanges: Welding Neck, Slip-On and Threaded. Each flange is provided with a pair of pressure taps for measurement of pressure drop in the flow through the orifice plate.
