Flange Supplier UAE

When industrial piping systems require reliable connections between pipes, valves, equipment, and other components, the correct flange specification is essential. Flanges must match the required pipe size, pressure class, material, facing, dimensions, and applicable standards.

JSS Pipes is a flange supplier in UAE providing industrial flanges for oil & gas, petrochemical, EPC, refinery, power generation, marine, and other industrial applications. Flanges can be supplied according to project specifications, applicable standards, material requirements, and required quantities.

For projects requiring high-strength connections, JSS Pipes also supplies forged fittings and flanges manufactured according to applicable industry standards.

Flange supplier in UAE providing ASME B16.5 industrial pipe flanges

ASME B16.5 Flanges

ASME B16.5 is a widely referenced standard for pipe flanges and flanged fittings. It covers requirements related to dimensions, pressure-temperature ratings, materials, marking, tolerances, testing, and other relevant characteristics for applicable flange products.

For projects specifying ASME B16.5, the required flange should be selected according to the specified nominal size, pressure class, material, facing, and other project requirements.

JSS Pipes can support requirements for ASME B16.5 flanges based on the specifications provided by the customer or project.

Types of Industrial Flanges

Different piping applications require different flange configurations. The appropriate type depends on the piping design, connection method, pressure requirements, accessibility, and project specification.

Weld Neck Flanges

Weld neck flanges are designed to be butt-welded to the pipe. Their configuration provides a continuous connection between the pipe and flange and makes them suitable for demanding piping applications where the project specification requires this connection type.

Slip-On Flanges

Slip-on flanges are fitted over the pipe and are typically welded in position. They can be used where the piping design and applicable specifications permit this type of connection.

Blind Flanges

Blind flanges are used to close the end of a piping system or equipment connection. They can also provide access for future modifications while maintaining a sealed connection when properly installed.

Socket Weld Flanges

Socket weld flanges are designed for insertion of the pipe into the flange before welding. They can be specified for certain smaller-diameter piping applications according to project requirements.

Threaded Flanges

Threaded flanges connect to pipes using internal threads rather than welding. They may be selected for applications where welding is not suitable or where the project specification specifically calls for a threaded connection.

Lap Joint Flanges

Lap joint flanges are used with stub ends and allow the flange to rotate around the pipe. This can be useful in applications where frequent dismantling or alignment is required.

Along with flanges, we work with contractors looking for reliable pipe fittings suppliers in UAE for complete industrial piping requirements.

ASME B16.5 Flange Classes

Pressure class is an important consideration when selecting an industrial flange. ASME B16.5 flange requirements include different pressure classes that are selected according to the applicable material, temperature, pressure, and project specification.

Common classes encountered in industrial piping include:

  • Class 150
  • Class 300
  • Class 600
  • Class 900
  • Class 1500
  • Class 2500

A higher class number does not simply represent a universal pressure value. The applicable pressure-temperature rating depends on factors including material and operating temperature.

For this reason, flange selection should always be based on the project’s approved piping specification and operating conditions.

ASME B16.5 Flange Dimensions

Flange dimensions need to match the piping system and the applicable standard. Depending on the flange type and size, dimensional requirements can include:

  • Outside diameter
  • Bolt circle diameter
  • Number and size of bolt holes
  • Flange thickness
  • Bore diameter
  • Overall dimensions
  • Facing dimensions

For ASME B16.5 flange dimensions, the exact requirements depend on the nominal pipe size, flange type, pressure class, material, and facing configuration.

Project drawings and technical specifications should therefore be checked before ordering.

Flange Materials

The material selected for a flange depends on the piping service and project requirements. Industrial projects may specify materials such as carbon steel, stainless steel, alloy steel, or other suitable grades.

Material selection can depend on:

  • Fluid service
  • Operating temperature
  • Operating pressure
  • Corrosion conditions
  • Mechanical requirements
  • Compatibility with connected piping
  • Applicable standards

The flange material should be compatible with the piping system and should meet the project’s specified material grade.
