1. More information about Hastelloy B2

 

Hastelloy B2 is a nickel-base wrought alloy with excellent resistance to hydrochloric acid at all concentrations and temperatures. Therefore, it has great resistance to stress-corrosion cracking and pitting. Hastelloy B-2 also features hydrochloric acid resistance at all concentrations and temperatures.

Available forms of Hastelloy B-2® are seamless pipe, welded pipe, seamless tube, welded tube, bar, wire, sheet, plate, forgings, pipe fittings and flanges.

Hastelloy B-2 Applications

Hastelloy B-2 has many different industrial applications, some of which include:

  • Chemical process applications
  • Vacuum furnaces
  • Mechanical components in reducing environments

2. Hastelloy B2 spectacle blind

Spectacle Blinds are generally applied to permanently separating pipesystems, or just to connect with each other. A Spectacle Blind is a steel plate cut into two discs of a certain thickness.
The two discs are attached to each other by section of steel similar to the nose piece of a pair of glasses. One of the discs is a solid plate, and the other is a ring, whose inside diameter is equal to that of a flange.

Spectacle Blinds be applied in systems, which regularly need to be separated from other installations. Normally, a Spectacle Blind is mounted in the "open" position so that flow through the pipe is possible. If the Spectacle Blind in the "close" position is rotated, the pipe is blanked off and no flow is possible.

Maintenance on a pipesystem can be a reason to rotate the spectacle in the "close" position. This run will take place through the hole, that is drilled in the connection piece. By loosening of all bolts, and partial removal of their, the Spectacle Blind can be rotated. After replacing the gaskets (new gaskets are to recommend), the bolts can be re-assembled and tightened.

3. Hastelloy B2 Spades and Ring Spacers

SPADES

Spades and Ring Spacers are basically the same as Spectacle Blinds, except that both are not attached to each other.

Spades and Spacers be applied in systems where maintenance is often not necessary, or in applications with large pipe sizes. Depending on the flange size and the Pressure Class, Spades can weigh hundreds of pounds. To prevent unnecessary weight to a flange connections, usually will be chosen not for a Spectacle Blind, but for 2 separate parts.

RING SPACER

So as for the Spectacle Blind already described, maintenance on a pipesystem can be a reason to temporarily replace a Ring Spacer for a Spade. By loosening of all bolts, and half of the bolts temporarily remove, the Spade or Spacer can be placed. After replacing the gaskets (new gaskets are to recommend), the bolts can be re-assembled and tightened.

A small problem is that we basically can not see, or a Spade or a Spacer mounted between the flanges. Therefore the handles are often specially marked, or both have a different design; a customer often provides its own specification.

What should never lack is, that in the handle, the diameter and the Pressure Class of a Spade or Spacer is engraved; this applies also for the Spectacle Blind.
