As the name suggests, stainless steel flanges are flanges made of an alloy called stainless steel. Here is why stainless steel flanges are worth your investment: Corrosion resistance : Corrosion is a major problem for clients using flanges due to chemicals and environmental factors. Therefore, it is ideal to choose stainless steel flanges that can withstand these conditions. Stainless steel is a great choice as it is highly resistant to corrosion. Durability: Stainless steel is one of the most durable alloys and can withstand harsh environmental conditions. Tolerance to extreme temperatures: Flanges made of stainless steel can withstand high temperatures. Some grades can withstand scaling and can maintain their strength even at very high temperatures, while others show excellent durability at extremely low temperatures. Aesthetics: Stainless steel flanges are available in a variety of surface finishes which gives them an aesthetic look. It is easy to clean and maintain, resulting in high quality, attractive appearance. Stainless steel flanges are available in a wide variety of grades of stainless steel. Each grade differs in chemical composition and has different properties. There are various grades of stainless steel flanges available to suit the client's requirements. One must put its intended applications into consideration when choosing the grade of stainless steel flange to use. For example liquids, gases, etc.)

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.

A slip-on flange is connected to the pipe or the fittings by two fillet welds, one executed inside and one outside the cavity of the flange. The bore size of a slip-on flange is larger than the outside diameter of the connecting pipe, as the pipe has to slide inside the flange to be connected by the execution of a fillet weld. Slip-on flanges are also defined Hubbed Flanges and they are easy to recognize due to their slim and compact shape.

Threaded flanges are joined to pipes by screwing the pipe (which has a male thread, generally NPT per ASME B1.20.1) onto the flange, without seam welds (in certain cases, though, small welds are applied to increase the strength of the connection). Threaded flanges are available in sizes up to 4 inches and multiple pressure ratings, however, they are used, mostly, small size piping in low pressure and low-temperature applications, like water and air utility services. Threaded flanges are also a mandatory requirement in explosive areas, such as gas stations and plants, as the execution of welded connections in such environments would be dangerous.

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.

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.

ANSI flanges facilitate the alignment of the bolt holes between the two mating flanges, a feature that is helpful in many circumstances, such as the installation of large diameter pipelines, subsea and offshore pipelines, pipe works in shallow waters and similar environments. ANSI flanges suit oil, gas, hydrocarbons, water, chemical and other demanding fluids in petrochemical and water management applications. In the case of a large diameter pipeline, for instance, the pipe is fitted, at one end, with a standard welding neck flange, and with a swivel flange at the other end: by simply rotating the swivel flange on the pipe, the operators can achieve a perfect alignment of the bolt holes in a way easier and faster way

Reducing flanges, otherwise called reducer flanges, have an opposite function than expander flanges seen above, i.e. they are used to decrease the bore of a pipeline. The bore of the run pipe can be safely reduced by only 1 or 2 sizes (otherwise a solution based on the combination of a butt weld reducer and a standard flange has to be used). Reducing flanges are available in most sizes and material grades, and are not generally available from stock. Reducing flanges follow the same considerations in terms of specifications, sizes and material grades as expander flanges.

Orifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. Pairs of pressure Tappings, mostly on 2 sides, directly opposite each other, are machined into the orifice flange. Orifice Flange Unions are designed &; manufactured to AGA, ASME, and ISA recommendations. We are manufacturing wide array of the following types- Raised Face weld neck orifice flanges Slip on threaded ring joint corner tap weld neck orifice flanges Raised Face slip-on orifice flange Ring-Type joint weld neck orifice flanges Corner tap orifice flanges

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.

Standard Forged Flanges (Weld-neck, Slip-on, Socket-weld, Lap-joint, Blind and Screwed Types) are manufactured by us to specifications of ASME B16.5, ASME B16.47, ASME B16.48, BS EN 1092, BS 4504, API-605, API-590, MSSSP44, DIN 2632 to 2638, DIN 2576, 2642, 2527, 2566. Flanges cover a full range of pressure ratings of these specifications (150 â?? 2500 psi for ASME & PN6-PN400 for DIN / EN flanges). Non-standard flanges are made upto a diameter of 4500 mm and the weight not exceeding 5,000 kgs.

A flange connector is a device that allows the connection of many types of hoses and fittings onto a flanged pipeline. Typically manufactured from stainless or high-carbon steel, a flange connector is connected to a flanged pipe with bolts, and a gasket is sandwiched between the pipe flange and the connector. Common in manufacturing facilities, a flange connector is often used to allow a smaller and more manageable hose to be split off from a large feeder pipeline. A flange-type connector can also be used to block off a pipeline. Flange connector provides safe and easy connections between process lines and instruments. It provides Hy-Lok tube connection ends by a lap joint pipe flange to ANSI B 16.5 or BS 1560. Both "smooth" and "serrated" surface finishes are available. For identification of serrated surface finish, groove is provided.
