00:00Welcome to our channel. Today we'll learn about the seven main types of flanges used in piping
00:05systems, their structure purpose and where each type is used in real world industries.
00:11Weld Neck Flange. This flange has a long tapered neck, providing excellent stress distribution.
00:16It's but welded to the pipe, making it perfect for high pressure and high temperature applications
00:20such as in refineries, chemical plants and power stations. Slip on flange. The pipe slips into the
00:26flange bore before welding. It's welded on both sides, inside and outside. Slip on flanges are
00:32easy to align and mostly used in low pressure systems like cooling water or firefighting lines.
00:38Three Threaded Flange. This type is screwed directly onto a threaded pipe. No welding required. It's
00:43used for small diameter and low pressure applications, often where welding is risky or
00:48not possible, like gas lines. Lap Joint Flange. This flange works with a stub end. The flange itself
00:54doesn't contact the fluid and it can rotate freely, making alignment and dismantling very easy.
01:00Ring Type Joint. RDJ. Flange. Ideal for corrosive environments and food processing plants. This high
01:06integrity flange has a machined groove that holds a metal ring gasket. When tightened, it forms a strong
01:12leak-proof seal. RDJ flanges are used in oil and gas pipelines, offshore platforms and high pressure
01:19steam systems. Orifice Flange. This flange is used with an orifice plate to measure the flow rate of
01:25liquids or gases. It has pressure tap holes for instruments. You'll find these in refineries and
01:30chemical process lines. Glit Flange. Socket Weld Type. In this flange, the pipe slips into a socket and
01:36is welded around the hub. It's compact, strong and used for small bow. High pressure systems such as
01:42hydraulic or steam lines. So, each flange type has a unique role depending on the system's pressure,
01:48temperature and maintenance needs. Choosing the right flange ensures safety, durability and efficiency.
