Orifice Flange

Orifice flanges are essential for measuring fluid flow in pipelines using flow nozzles. They feature pressure tappings, eliminating the need for separate wall tapings. This assembly includes flanges, an orifice plate, bolts, nuts, gaskets, jacking screws, and plugs for easy element removal. When assembled during pipeline connections, it’s called an orifice flange amalgamation, mainly used for metering gas or liquid flow. Emcor Engineering offers customizable orifice flanges in various sizes and specifications, all provided with test certificates, and competitively priced.

SPECIFICATIONS

Orifice flanges are placed in a straight pipe section to minimize turbulence near the plate. Typically, they require ten pipe diameters upstream and five downstream for optimal performance. Orifice flanges are commonly paired with orifice meters for precise fluid flow measurement, especially for oil and gas pipelines. Standard assembly components include gaskets, nuts, bolts, plugs, plates, flanges, and jacking screws, simplifying the removal of the primary flow element. Emcor Engineering is a leading manufacturer and exporter of these components.

Lapped Joint Flange

Emcor Engineering offers a range of lap joint pipe flanges in various materials and sizes to suit client needs. These flanges feature a two-piece design, requiring butt welding of the stub end to the pipe using a backing flange. This design is ideal for space-constrained systems and those requiring frequent maintenance. Materials include Carbon Steel, Alloy Steel, Stainless Steel, Hastelloy, Inconel, Monel, and duplex Steel. Lap Joint Flanges share common dimensions with other flanges but lack a raised face. They closely resemble Slip On flanges with a bore intersection radius for the Stub End. However, their pressure-holding capability is similar to Slip On flanges, and the assembly’s fatigue life is one-tenth that of Welding Neck flanges.

SPECIFICATIONS

The lap joint is a versatile flanged joint used in various industries. It employs a separate flange for bolting and axial load application. Lap joint connections are ideal for exotic or costly piping materials, allowing for economical use of a carbon steel flange with only the lap joint stub end in the line material. This type of flange finds extensive applications in chemical, oil & gas, paper & pulp, power generation, food processing, structural piping, and various process industries.

LONG WELDNECK FLANGE

Emcor Engineering is a renowned manufacturer and exporter of Long Weld Neck Flanges in India and across the globe. We are dedicated to delivering cost-effective, reliable, and top-quality flanges to our valued customers. Long Weld Neck Flanges (LWN flanges) are specifically employed in high-pressure scenarios, with integral hub weld neck flanges being utilized for elevated pressure applications. In such situations, the welds are strategically positioned away from the flange’s ring to prevent the amalgamation of bending and weld stresses.

The design of the Long Weld Neck Flange serves as a substitute for a Weld Neck Flange and a piece of pipe in a bolt-up connection to the vessel. This innovative design minimizes stress on the flange neck by transferring it to the base, where it connects with the vessel. Among the various self-reinforced nozzle designs, the Long Weld Neck Flange is the most commonly used, with two distinct types available: the heavy barrel featuring a long weld neck and the equal long weld neck barrel, which comes in a variety of shapes.

SPECIFICATIONS

This type of flange, commonly known as a long weld neck flange, serves to effectively manage variations in pressure and temperature within the liquid flowing through a pipeline. Long weld neck flanges are frequently employed as secure anchors in water mains due to their capacity to endure elevated pressures. They are also suitable for connecting extensive networks of pipes, such as those within industrial facilities. Long weld neck flanges can play a crucial role in expansion bends, as well as in extending or reducing pipe sizes. They become essential components in vessels requiring extended necks or hubs to extend their functionality. These flanges find extensive applications in industries like chemical, petroleum, and oil & gas, where they must withstand substantial stress and temperature fluctuations. Emcor Engineering is a notable manufacturer and exporter of such fittings.

Slipon Flange

Emcor Engineering is a prominent manufacturer and exporter of high-quality Slip-on Flanges, essential for pipe joint disassembly. These flanges come in various sizes to accommodate high-flow systems, with a simple match to the pipe’s outer diameter. Installation involves fillet welding on both sides to securely attach the flange to the pipe. A Slip-on Flange connects via two fillet welds, one inside and one outside the flange cavity. The flange’s bore size is larger than the pipe’s outside diameter, allowing it to slide inside for welding. Known as “Hubbed Flanges,” they are compact and available in materials like Alloy Steel, Carbon Steel, Stainless Steel, and more. 

SPECIFICATIONS

Emcor Engineering manufactures slip-on flanges using various methods like forging, steel cutting, and casting. Among these, forging offers the highest quality but comes at a higher price. When purchasing slip-on flanges, consider the specific application, typically for non-corrosive, moderate-pressure environments. These flanges are essentially rings that slide onto the pipe end, extending beyond it for welding. The outer diameter of slip-on flanges is also welded on the backside. They are cost-effective and easier to align than weld neck flanges and can serve as lap joint flanges when paired with Type B or Type C stub ends.

Socketweld Flange

Socket-weld flanges are ideal for smaller pipes in low-temperature, low-pressure situations. They feature a simple installation process where the pipe is inserted into the flange and secured with a multi-pass fillet weld. These flanges have a recessed area serving as a pipe depth guide. Initially designed for high-pressure small diameter piping, they offer 50% more fatigue strength than slip-on flanges. A space is left between the flange and pipe to ensure proper bore dimension. In socket weld flanges, a pipe is inserted into a socket and secured with a single fillet weld on the flange’s exterior. Emcor Engineering is a leading manufacturer and exporter of these fittings.

SPECIFICATIONS

Socket weld flanges are primarily used for small pipe sizes (½ to 2 inches) and offer mechanical strength comparable to slip-on flanges but with only one weld. They have the same static strength as slip-on flanges but 50% greater fatigue strength than double-welded slip-on flanges. These flanges connect to the pipe with a single fillet weld on the outside of the flange, requiring no weld preparation, reducing construction costs, and avoiding penetration of the flange bore. Emcor Engineering is a prominent manufacturer and exporter of these socket weld flanges.

Weldneck Flange

Emcor Engineering offers weld neck flanges in a range of materials, including stainless steel, alloy steel, carbon and LTCS, copper & nickel alloys, Super Duplex, Nickel, Monel, Inconel, Hastelloy, Aluminium, etc. These flanges require butt welding for installation, providing exceptional integrity and performance in high-pressure and high-temperature systems with multiple bends. Weld neck flanges, also known as tapered hub flanges, distribute stress to pipes, reducing stress concentration. There are two designs: one for pipes and another for process plants. Made through forging, these round fittings extend beyond the circumference rim and are welded to pipes.
