IBR Approved Flanges and IBR Blind/ Slip On/ WNRF Flange manufacturer

ASME B16.5 Class 150 IBR Flanges manufacturer In India And supplier In Mumbai, India

Flanges made up of various standards and grades are available with us the ones manufactured as per Indian Boiling standards are known as IBR Approved Flanges. These flanges can be used in high temperature and high pressure environments. IBR Flanges manufacturer In India produces these flanges in various shapes such as socket weld, neck weld, and so on. AWWA C207 IBR Approved Blind Flanges can be made up of various materials such as stainless steel, carbon steel, alloy steel, and mild steel. Moreover, these EN 1092-1 IBR Pipe Flanges can be used under high wear and tear conditions.

BS 4504 IBR Carbon Steel Slip On Flanges can easily be slid over the pipes and if required they can be welded as well. The ones that are forged are formed by the use of mechanical and thermal energy. Schedule 40 IBR Plate Flange is commonly used in reducing connections. These flanges come in a pressure rating of 2000-6000. They can also be coated if required by the customer. Class 300 IBR Approved Lap Joint Flanges are available in the flat face or the raised face and are available in ½ inch to 24 inches. They are mostly available in 4, 8, 12, 16, 20, 24, bolts.

DIN 86029 PN10 IBR Stainless Steel Flanges offer flawless performance and long service life. Most of the time the lap joint flanges are used in tandem with the stud end this is because they are not produced with a raised face. EN 1092-2 PN16 IBR Approved Socket Weld Flanges and the stub ends that are used are held together due to the pressure of the bolt. They also have a good load bearing capacity. MSS SP-44 IBR Weld Neck Flange has the freedom to swivel around the pipe, which assists in alignment with the bolts. carbon steel can be used due to lack of contact between the flange and the fluid in the pipe. Furthermore, it can be salvaged for reuse.
