A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.

We, Jaydeep Impex are largest exporters of FLANGES We buy FLANGES from JAPAN, USA, EUROPE and supply to Middle East, Europe, South America with Third Party Inspected from Lloyds, SGS, Bureau Veritas & TUV. Our FLANGES dimensions and material grades are according to ASTM, ANSI/ASME, MSS-SP, DIN, BS, EN and EEMUA standards and are provided with material test certificates according to EN10204-3.1.

Flanges are not a one-type-fits-all sort of solution. Sizing aside, matching the ideal flange design to your piping system and intended usage will help to ensure reliable operation, a long service life, and optimal pricing.

Materials for Flanges

Pipe flanges are manufactured in all the different materials like stainless steel, cast iron, aluminum, brass, bronze, plastic etc. but the most used material is forged carbon steel and have machined surfaces.

In addition, flanges, like fittings and pipes, for specific purposes sometimes internally equipped with layers of materials of a completely different quality as the flanges themselves, which are “lined flanges”.

The material of a flange, is basically set during the choice of the pipe, in most cases, a flange is of the same material as the pipe.

All flanges, discussed on this website fall under the ASME en ASTM standards, unless otherwise indicated. ASME B16.5 describes dimensions, dimensional tolerances etc. and ASTM the different material qualities.

Bolted Flange connections

A bolted flange connection is a complex combination of many factors (Flange, Bolts, Gaskets, Process, Temperature, Pressure, Medium). All these various elements are interrelated and depend upon one another to achieve a successful result.
The reliability of the flanged joint depends critically upon competent control of the joint making process.

MAKING THE CONNECTION: FLANGE FACING TYPES

Flange design is only the start when considering the ideal flange for your piping system. Face types are another characteristic that will have a major impact on the final performance and service life of your flanges.

Facing types determine both the gaskets needed to install the flange and characteristics related to the seal created.

Common face types include:

• Flat Face (FF): As the name suggests, flat face flanges feature a flat, even surface combined with a full face gasket that contacts most of the flange surface.
• Raised Face (RF): These flanges feature a small raised section around the bore with an inside bore circle gasket.
• Ring Joint Face (RTJ): Used in high-pressure and high-temperature processes, this face type features a groove in which a metal gasket sits to maintain the seal.
• Tongue and Groove (T&G): These flanges feature matching grooves and raised sections. This aids in installation as the design helps the flanges to self-align and provides a reservoir for gasket adhesive.
• Male & Female (M&F): Similar to tongue and groove flanges, these flanges use a matching pair of grooves and raised sections to secure the gasket. However, unlike tongue and groove flanges, these retain the gasket on the female face, providing more accurate placement and increased gasket material options.

Many face types also offer one of two finishes: serrated or smooth.

Choosing between the options is important as they will determine the optimal gasket for a reliable seal.

In general, smooth faces work best with metallic gaskets while serrated faces help to create stronger seals with soft material gaskets.

THE PROPER FIT: A LOOK AT FLANGE DIMENSIONS

Apart from the functional design of a flange, flange dimensions are the most likely factor to impact flange choices when designing, maintaining, or updating a piping system.

However, you must consider how the flange interfaces with the pipe and the gaskets in use to ensure proper sizing.

Common considerations include:

• Outside diameter: The distance between two opposing edges of the flange face
• Thickness: A measure of the thickness of the outer attaching rim
• Bolt circle diameter: The distance between opposing bolt holes when measured from centre to centre
• Pipe size: A designation of the pipe size with which the flange corresponds
• Nominal bore size: A measurement of the flange connectors inner diameter

Common classifications include:

• 150#
• 300#
• 600#
• 900#
• 1500#
• 2500#

Exact pressure and temperature tolerances will vary by materials used, flange design, and flange size. The only constant is that in all cases, pressure ratings decrease as temperatures rise.

FLANGE STANDARDS AND MARKINGS

To help make comparison easier, flanges fall under global standards established by the American Society of Mechanical Engineers (ASME) — ASME B16.5 & B16.47.

If you’re attempting to replace or verify existing parts, all flanges must include markers — typically on their outer perimeter — to aid in the process.

These markers also follow a strict order:

• Manufacturer logo or code
• ASTM material code
• Material Grade
• Service rating (Pressure-temperature Class)
• Size
• Thickness (Schedule)
• Heat Number
• Special designations, if any — for example, QT for Quenched and tempered or W for repair by welding
