What is BS4504 Flange?
The BS4504 flange is a British standard circular flange. The flanges are designed in sizes 15 NB to 1200 NB or DN 10 to DN5000. These flanges have excellent corrosion resistance properties and can be easily threaded or welded. The BS4504 flanges are designed in standard flanges of class 150 lbs to class 2500 lbs. They are available in raised, flat, and ring-type joint faces. These flanges can be forged, heat-treated, and machined in the system.

BS4504 PN16 vs BS4504 PN25
The BS4504 PN16 and BS4504 PN25 are pressure classes of respective flanges. Both these flange types can be differentiated on key features.

The BS4504 PN16 is designed to work in pressurized grades up to 16 bar. A BS4504 PN25 grade works well in pressurized grade up to 25 bar.
The BS4504 PN25 grade has slightly higher pressure-holding capacity compared to the PN 16 grade.

Difference between BS4504 PN10, PN40 and PN64
PN 10, 40, and 64 are the three pressure classes that are seen in different conditions. A BS4504 PN10 grade is designed to work in a pressure class of 10 bar, while the PN 40 grade works well in a pressure class up to 40 bar. The PN 64 grade works at slightly higher pressures and can withhold a pressure class up to 64 bar.

What is the difference between British Standard BS4504 and ASTM?
The BS4504 is designed in the British standard that covers products of tubes, pipes, and other equipment suited to meet these standards. The ASTM or American Society for Testing and Materials are manufactured from American standards of products of pipes and equipment of these standards.
