Large diameter flanges supplier in UAE

ASME B16.47 flange manufacturer in Dubai


ASME B16.47 Flange

How do you solve the manufacturing problems associated with an ASME B16.47 flange?

This American standard covers flanges from NPS 26 to 60 and states materials, dimensions, marking, testing, etc. Our company is an ASME B16.47 series B flange supplier in UAE with stringent quality control to enforce compliance and a custom portfolio.

We source products per tolerance norms to optimise the series B weld neck flange performance. The gasket thickness gets measured across the metallic region, excluding fillers.

How does the size of an ASME B16.47 series B flange affect its pressure rating?

Industrial clients acquire these flanges to handle ratings of 75 to 900. An ASME B16.47 Series B slip on flange should use the stated number of bolts and specified diameters.

Note: As the rating increases, the thickness, diameters, and bolting requirements go up.

No need to pay extra, when you can buy ASME B16.47 lap joint flange stockist with exact sizes

How does the installation of bolts affect the performance of an ASME B16.47 series A flange?

These flanges are heftier and take more load without leaks. An ASME B16.47 series A flange has larger bolt circle diameters than Series B. So, for instance, you need 28 bolts of 11/4” diameter for a 30-inch flange for ANSI B16.47 series A class 150 flanges.

What types of gaskets are used with ASME B16.47 series B slip on flange?

Often used in refurbished systems, an ASME B16.47 series B slip on flange has a smaller bolt circle diameter. It reduces post-installation movement. Generally, these compact flanges get preferred for lower criticality.

Customers can use spiral wound or jacketed gaskets. The manufacturer must use appropriate tolerances for the outside/inside diameters and the centering ring. For example, for NPS 26 to 34, the level for the inner diameter is ±0.03”. Notably, ring type joints are unavailable for Series B.

What is the recommended procedure for inspecting a B16.47 series B blind flange?

Blind flanges can seal piping sections for repair and maintenance actions. A B16.47 series B blind flange is usually not subject to non-destructive inspection, or NDI. The standard procedure is only a precautionary measure of the thickness.

How are large diameter flanges tested and certified for use in various applications?

Integrated testing of large diameter flanges ensures leaks, defects, contamination, corrosion, etc., are absent. Manufacturers perform radiography and ultrasonic testing to ascertain the quality. They also assess the mechanical properties via tension and hardness tests.

Customers should verify the quality through the MTC and Raw Materials Certificate or issue a third-party examination.
