A welding neck flange (WN) features a long tapered hub that can be welded with a pipe. This flange type is used, normally, in high-pressure and high/low temperatures applications that require an unrestricted flow of the fluid conveyed by the piping system (the bore of the flange matches with the bore of the pipe). The absence of pressure drops prevents negative effects as turbulence and erosion/corrosion of the metals in the proximity of the flanged joints. The tapered hub allows a smooth distribution of the mechanical stress between the pipe and the weld neck flange and facilitates the execution of radiographic inspections to detect possible leakages and welding defects. The dimension of the flange (NPS and the pipe schedule) shall match the dimension of the connecting pipe.
Blind Pipe Flange is used whenever a line must be capped off at a flange. It is good practice to install blind pipe flange at the end od header or at location where future tie-ins are anticipated. Blind pipe flanges are also used extensively for manways, in which case a davit is recommended for ease in handling the unbolted manway cover. Blind pipe flange is specified by ANSI B16.47. We offers blind pipe flange in A105, A105N, SS316, SS304, A20, High Yield & Nickel Alloys.
A split flange is a type of flange that can be easily installed on pre-existing piping. It is made up of two interlocking pieces that fit securely together using nuts and bolts or welding it into place. Because it is made of two parts, split flanges are used to reinforce weakened areas of piping, or to add an attachment in places conventional flanges cannot. Split-flange fittings use rubber O-rings to seal joints and contain pressurized fluid. The O-ring sits in a groove on the flange, and then mates with a port's flat surface. The flange is then attached to the port with four mounting bolts. The bolts tighten downward onto the clamps of the flange, thereby eliminating the need for large wrenches to connect the components of large-diameter tubing.
Screwed flange are often used for small diameter, high pressure requirements. Screwed flanges with a hub have published specifications that range from 1/2 thru 24. Pressure class: Class 150 to Class 2,500, PN 2.5 to PN 250 and Facing: RF / RTJ. Screwed flanges are threaded in the bore which match an external thread on the pipe. Screwed flanges are used with pipes that have external threads. The benefit of these flanges is that it can be attached without welding.
A pipe flange connects piping and components in a piping system by use of bolted connections and gaskets. Most commonly used flanges are weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange and lap joint flange (RTJ Flange). This type of connection in a pipe flange allows for ease of disassembly and separation for repair and regular maintenance. Most common specification for carbon steel and stainless steel flange is ANSI B16.5 / ASME B16.5.
Long weld neck flanges (LWN) are similar to weld neck flanges, with the exception that the neck (tapered hub) is extended and acts like a boring extension. Long weld neck flanges are generally used on vessels, columns or barrels. These flange types are available also in the heavy barrel (HB) and equal barrel (E) types
Ensures a watertight seal where pipes pass through the walls of any structure below groundwater level. Puddle Flanges are used to seal around the outside of pipes that are required to pass through concrete structures. They are installed during construction. Pipes passing through concrete will not bond to the concrete and water can pass along the external surface of the pipe. Puddle Flanges act as a barrier to this flow. The seal is clamped onto the pipes and stops this direct route. The seal body is compressed during the pouring process and should the concrete shrink during curing the rubber relaxes and maintains a seal against this flow path. Puddle Flanges provide an effective solution against water penetration along the external surface of pipes that pass through concrete structures such as tanks, manhole chambers, shafts, floor slabs and basements.
