About 304L (UNS S30403)

Type 304L is a lower carbon variant of Grade 304 – the steel can be welded without the resulting issue of carbon precipitation (precipitation of chromium carbide as heat is applied during the welding process which depletes the chromium element of the steel thus reducing its anti-corrosive/oxidation effectiveness).

As a result, Type 304L stainless steel is a sought after material for use in severely corrosive conditions. Weld annealing is only necessary in applications where stress loads are excessive.

This steel Grade is found in a variety of commercial sectors, particularly in the chemical industry.

About: A182 ANSI B16.48 F53 Spectacle Blind Flange

The spectacle blind flanges have three types:spacer,spade(paddle flange),spectacle blind flange.A spectacle blind flange is a combination of a spade and a spacer.

All these three types of spectacle flanges are used in piping systems or pressure vessels where the flow needs to be interrupted from time to time.They are installed between one pair of pipe flanges and able to rotate or ‘swing’ into and out of position to interrupt or allow the flow,they are used in the piping system as “Open” and “Closed” function.

Maintenance on a pipe system 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,the bolts can be re-assembled and tightened.It is necessary that the pipeline should be valved off and pressure relieved before loosening the flange bolts.

To prevent unnecessary weight to a flange connections,designer usually will choose the seperated two parts (spacer and spade) instead of the spectacle blind flange.
