What is the variation among Class 150 Flange, Class 300 Flange & Class 600 Flange?
Bhansali Metalloys Inc supply a good vary of Flanges, which has a number of outstanding options like dependable, well tested, safe usage, durable, low maintenance, ranked material, etc. we tend to procure and provide wide assortment of those Stainless-Steel Flanges that are factory-made from qualitative raw material by our trusted experts. The inputs used in the fabrication of these products are purchased from certified suppliers of the industry after severely examining their quality and sturdiness.
Steel Flanges are categorized as per ASME B16.5 standard. The pressure rating of flange scale from Class 150 to Class 2500. The label “lb”, “class” and “#” are used equivalently to identify the pressure rating of the flange. The truth is that 150 lb has no connection to 150 psi and so does the 300 or 600 lb does not correspond to 300 or 600 psi pressure rating. Pressure rating of the flange turn on the material (A105, stainless, nickel alloy etc.), the heat treats condition and pressure “class”. Here we will use the phrase “class” to NOT confuse it with pressure “rating”. So, what is class 150 flange or ASME B16.5 class 150 flange, as the question raised by many buyers.
Let’s define the pressure rating of steel pipe flange. The table below shows the pressure and temperature rating of ASTM A105 Carbon Steel Flange:
