Flange Types

Threaded Flanges  Flanges Threaded Flanges are also known as screwed flange, and it is having a thread inside the flange bore which fits on the pipe with matching male thread on the pipe.
Socket-Weld Flanges  Flanges Socket-Weld Flanges has a female socket in which pipe is fitted. Fillet welding is done from outside on the pipe.
Slip-On Flanges  Flanges Slip-On flange has a hole with matching outside diameter of pipe from which pipe can pass. The flange is placed on pipe and fillet welded from both inside and outside.
Lap Joint Flanges  Flanges Lap flange is having two components, a stub end, and a loose backing flange. Stub end is butt welded to the pipe and Backing flange freely move over the pipe.
Weld Neck Flanges  Flanges Weld neck flange are most widely used flanged in process piping. It gives the highest level of joint integrity due to Butt-welded with a pipe.
Blind Flanges Flanges The blind flange is a blank disc with bolt hole. These types of flanges are used with another type of flange to isolate the piping system
Screwed Flange Flanges 3Screwed Flange is used to connect other components in non-critical applications, low-pressure in which no welding is required.
Reducing Flange Flanges A reducing flange consists of a flange with one specific diameter having different bore and smaller diameter. It s used to change the diameters in piping system.
Forged Flange Flanges They are designed by using corrosion free substance and using an advanced technology. Our team of experts identify each and every product to ensure the best quality and flawless of these products available at suitable rates
Orifice Flange Flanges Orifice Flange helps to measure the flow of liquids and gases using orifice meters located on the outside diameter of the flanges. The main purpose of the orifice flange identifies the flow rate of either liquid or gas in the pipeline system.
Spectacle Flange Flanges A spectacle flange is a specialty flange made of two metal discs attached in the middle by a small section of steel. Spectable flanges get their name because they look like a pair of reading glasses, or spectacles.
