Detailed Information

Prashaant Steel & Alloys is known as the pinnacle in the world of metal market for the best quality Threadolets production in India. The Orifice Flanges with the stub end assembly is normally used in piping systems which require regular dismantling for inspection and cleaning. These flanges slip over the pipe, and are not welded or otherwise fastened to it. Bolting pressure is transmitted to the gasket by the pressure of the flange against the back of the pipe lap (Stub End). Orifice Flanges are similar to other types of industrial flanges, but it does not have a raised face. Orifice Flanges are used in conjunction with “Orifice Flanges”.

Orifice Flanges are generally manufactured from stainless steel bar stock. Stainless Steel Orifice Flange plate is not interchangeable. Which means that the orifice plate of the water line cannot be used into the hydrocarbon line. Orifice Flanges generally come with either Raised Faces or RTJ (Ring Type Joint) facings. Orifice flanges 150 lbs tend to be butt-welded into the pipeline. The inside diameter also referred to as the bore diameter of the pipe must be specified when ordering these Stainless Steel Orifice Flange.

Orifice Flanges are utilized with orifice meters to gauge the flow rate of either fluids or gases in the separate pipeline. They are, for all concentrated purposes, equivalent to weld neck and slip-on ribs with extra machining. Orifice flanges might be given in one of three kinds of ribs: Welding Neck, Slip-On, and Threaded. When two Orifice Flange Jis 16k are used together, they are known as an orifice flange union.

Orifice flange accompanies a pipe tap for estimating the pressing factor drop of the course through a hole plate. This makes a different Orifice transporter or tapping in the pipe divider pointless. Orifice plates don’t accompany the flanges and are measured dependent on the prerequisites of the interaction. One/Two jack screws are utilized to spread the spines separated to change the Orifice plate. Orifice Flanges are presented in a straight run of the pipe to avoid roughness at the plate.
