En 1092-1 flange

En 1092-1 Flange

EN is an European standard that concerns pipes and flanges. They establish the requirements for steel flanges based on their nominal pressure (PN) and Dimension (DN). En 1092-1 defines different types of flanges and their sealing surface, along with tolerance, threading, and labeling. There are different types of Bs en 1092 flanges which can be customized according to the requirements given by the client. The En 1092 standard flanges can be used in industries such as oil and gas, petrochemicals, and allied industries. There are different types of flanges in the En 1092 flanges standard and they come in different shapes, sizes, and used for different types of applications.

Before you buy EN 1092-1 weld neck flange in Dubai, check the manufacturing origin, view UNI EN 1092-1 plate flange advantages and disadvantages

The En 1092-1 Flanges dimension and size are dependent on various factors, like:

  • The outer diameter of the body
  • The diameter of the bolt circle
  • Bolt hole diameter
  • Bolt hole alignment
  • The blind thickness
