Skyland Metal & Alloys Inc. are a well known ASME B16.5 Class 150 Flange manufacturers & suppliers of Slip On Flanges Class 150 in india in the steel market. We specialise in manufacturing a comprehensive range of Class 150 Weld Neck Material, Slip On Flanges Class 150. Check ASME B16.5 Class 150 Flange Dimensions. ASME B16.5 Flanges 150 lb come in following types- slip on flanges class 150, ANSI b16.5 class 150 forged flanges and ANSI b16.5 class 150 lap joint flanges, ANSI b16.5 class 150 threaded flanges, class 150 blind flanges and class 150 pipe flanges. According to ANSI b16.5 class 150 welding neck flanges are made of seven primary Pressure Classes. One class’s flange can handle more pressure than another class flange, because it is constructed with more metal and can withstand more pressure. Number of factors can impact the pressure capability of a flange.
The ANSI B16.5 class 150 flange pressure temperature rating or Pressure Class for flange are given in pounds (lb). Different naming conventions are used to indicate a Pressure Class such as ansi b16 5 150 Lbs or 150lb or Class 150 or 150#, all are means the same. Flange can withstand different pressures at different temperatures. standard class 150 flanges covers size NPS ½” to 24” Flanged Fittings and Pipe Flanges. Additional factors are that Welding neck flange asme b16 5 class 150, Socket weld flange and MSS-SP-114 Threaded & class 150 pipe flanges can be constructed from different materials, such as cast and ductile iron, stainless steel, carbon steel, alloy steel etc.

The American National Standards Institute or the ANSI Class 150 Flange is a system of standards with regards to the dimensions for 150 lb steel flange dimensions like - slip-on, weld neck, threaded, socket weld, lap joint, and blind flanges. The 150 lb raised face flange dimensions for facing, studs and bolts are also included in the ANSI Class. 150 lb flange dimensions are covered in ASME B16.5. The 150 lb flange dimensions metric is known to cover Pipe Flanges in addition to Weld neck 10 150 lb flange dimensions Fittings for size NPS ½ inch to 24 inch for above NPS 26 inch to 60 inch it should be as per ASME B16.47.
We have large inventory of different types of stainless steel class 150 flanges, ASME B16.5 Class 150 Flange, class 150 weld neck flange materials, rf class 150 flanges are supplied in cities such as Ahmedabad, Bangalore, Ludhiana, Delhi, Chennai, Bhosari, Ghaziabad, Rajkot, Pune, Vadodara. We Also class 150 flange material, ANSI b16.5 class 150 blind flanges supply minimun quantity of class 150 flange types, carbon steel flanges and stainless steel flanges & Alloy steel flanges - asme/ANSI class 150, ANSI b16.5 class 150 forged flanges, ANSI b16.5 class 150 lap joint flanges in countries like, Finland, Netherlands, France, China, Sweden, Germany, Canada, Italy.
What is Class 150 Flange?

Steel flanges are classified as per ASME B16.5 standard & ANSI B16.5 standard. The pressure rating of flange (Stainless, Carbon, Alloy) ranges from 150# to 2500#. The term "lb" (Flanges 150 lb), "class (Class 150 Flange)" and "# (150# flange)" are used interchangeably to designate the pressure rating of the flange. 150 lb has no relation to 150 psi and so does the 300 or 600 lb does not correlate to 300 or 600 psi pressure rating. Pressure rating of the flange depends on the material (A105, nickel alloy, stainless etc.), the heat treat condition and pressure "class". All dimensions are provided in both mm and inch units Like class 150 flange dimensions in mm and ansi 150 flange dimensions in inch. The two most important unit system shall be used respectively and exclusively. The Flanges of ASME B16.5 Class 150 flanges can be furnished by Flange with pipe flanges.
