What Is Stainless Steel 316 Spiral Wound Gasket?

Stainless steel 316 is an excellent material to manufacture gaskets for general usage. Applications that require temperature and corrosion resistance have the most use of a stainless steel 316 spiral wound gasket. Stainless steel 316 is among the most used grades that are known for its superior temperature rating and corrosion resistance. It is also stronger at elevated temperatures. It is composed of 16-18% chromium, 10-14% nickel, 2-3% molybdenum, and some carbon. It is considered to be significantly more corrosion-resistant than stainless steel 304, because of its higher molybdenum and nickel concentration.

What Is Gasket Spiral Wound Ss316 Pressure Rating?

The pressure rating of a gasket refers to its load-bearing capabilities. For a gasket spiral wound ss316, here are the different pressure classes: 150, 300, 400, 600, 900, 1500, and 2500. The higher numbers indicate an increase in pressure-bearing capabilities. Hence, a gasket with a pressure rating of class 300 can handle higher pressure than a class 150 gasket. The pressure class for gaskets is given in lbs. For instance, 150lb, 150 lbs, 150#, or class 150 – are all equivalent and mean the same thing. The pressure class is among the important factors that determine gasket selection.

What Is The Difference Between 316 SS Spiral Wound Gasket Inner Ring And Outer Ring?

The inner ring and outer ring of a 316 ss spiral wound gasket are among their important parts. While there are differences between the two, both play important roles in gasket sealing and performance. The inner ring ensures windings do not buckle inside the pipe. Thus preventing the situation commonly known as “bird’s nest” that happens where parts of the gasket get sucked in. The inner ring and the winding material are the same, which in this case is 316 stainless steel. The outer ring in an ASTM A182 ss 316 spiral wound style CG gasket, for example, is usually carbon steel. It also acts as the centering ring and is often known as the guide ring.

How are SS 316 Spiral Wound Graphite Filled Gasket manufactured?

When ordering an ss 316 spiral wound graphite filled gasket, one may choose any of the reliable manufacturers. As long as they follow the ASME B16.20 standards and use suitable equipment, you have a product that you can trust. Now, these gaskets are manufactured by winding together an alternate combination of preformed metal strips, and filler material. The filler, in this case, is graphite that creates a strong seal upon compression. Specialized equipment is used for manufacturing Werkstoff Nr. 1.4401 spiral wound style R gasket or any of the other types.

Where are 316 Stainless Steel Outer Ring Spiral Wound Gasket Used?

A 316 stainless steel outer ring spiral wound gasket has multiple uses in diverse applications. It is mostly regarded for its high temperature and pressure resistance, and its ability to fight corrosion.

Some of the industries that use these gaskets are:

  • Automobile industry (as exhaust manifold)
  • Paper and pulp industry
  • Marine applications
  • Valve and pump parts and so on.

A stainless steel 316 spiral wound style RIR gasket also has uses where chemical applications (especially acidic) are involved. It can be used with acids like sulfuric, hydrochloric, acetic tartaric acids, and so on.

316 SS Inner Ring Thickness Available

There are ASTM guidelines regarding the various aspects of a UNS S31600 spiral sound style CGI gasket. And the same goes for the inner ring thickness of a gasket. Now the 316 SS inner ring thickness can be from 2.97 mm to 3.33 mm (0.117 in. to 0.131 in.). Also, it has to be the same as the thickness of the outer ring. While the manufacturer has control over the filler material thickness, they cannot control that of the inner ring. However, some manufacturers may provide slightly thicker or thinner inner rings in spiral wound gaskets.
