What Does ASME B16 5 Mean?


ASME B16.5 are components that are used to fit together two pipes or a pipe with other components in a system. They could either be connected by bolt and nut or by welding together. ANSI B16.5 Flanges belong to the standard B16.5. industrial flange have a category that can hold the classes 150 through 2500 and their diameter ranges from ¼ inches to 24 inches. ASA B16.5 Class 600 Flanges belong in the same category but with a higher maximum pressure capacity. industrial pipe flange is a specification of forged flanges. ASME B16.5 pipe flange are preferred by our customers for their durability, corrosion resistance and excellent performance. Their applications and use cases vary. Class 600 Flanges have higher maximum pressure so that they can be applied in heavy duty systems.

What Is ANSI Class 150 Flange?

What Is ANSI Class 150 Flange?

ANSI B16.5 Class 150 Flange is a pressure class that can handle a maximum pressure of 285psi. Flange sizes from 26 inches and above are governed by ASME B16.5 standards. Class 150 Flanges are mutually the same except is heavier and costly with less bolt holes. 150 LB Flanges are commonly used in applications where the piping system is less than 14 inches in diameter.

As the leading ANSI B16.5 Flanges manufacturer in India, we also supply ASME B16.5 Flange which has high corrosion resistance against most oxidizing and reducing media. flange material are used in steel pipe lines where strength is the primary concern. DIN86029 PN10 Flanges can withstand pressure levels up to 10 bars. It is a rating system with Pression Number (PN) which indicates in bars how much pressure the flange can withstand. We also supply Non Standard Flanges and flanges used in oil and gas industry and many other varieties of stainless steel flanges.
