6 Best Materials Ideal for Pressure Vessel Applications

March 28, 2018

Pressure vessels are among the most vital equipment in most industries. These are basically special containers that are designed in a way to hold liquids and gases at a pressure, which is extremely different from the ambient pressure. Therefore, the material used to manufacture these pressure vessels need to be strong enough to withstand high pressure, and prevent the container from exploding. There are special materials required for this job. What are these materials? What properties make them ideal for this application? Are you interested to know? Please read the following post, which discusses the different materials used for pressure vessels and their properties.

What are the Different Materials Used for Manufacturing Pressure Vessels?

The materials used for pressure vessels go a long way into deciding its reliability and safe operation. Therefore, it is very important to make the right choice in selecting the perfect material for these containers. Here are some capable materials, which qualify for use in manufacturing high pressure vessels:

1. Titanium: There are several properties of this material, which make it ideal for pressure vessel application. These properties are as follows:

  • Capability of retaining its structural properties
  • Extremely resistant to corrosion
  • Requires very little maintenance
  • Excellent tensile strength ranging from 30,000 psi to 200,000 psi (210-1380 MPa)
  • Higher melting point compared to steel and aluminum materials
  • Great biocompatibility
  • Non-toxic in nature

2. Nickel Alloys: The following properties of the nickel alloys are the strong points, which make the material suitable for use in this application:

  • Provides excellent protection from thermal expansion
  • Offers great resistance to corrosion
  • Suitable for use in harsh environments
  • Extremely reliable, and capable of lasting for several years
  • Good resistance to oxidation and carburization

3. Stainless Steel: Pressure containers require robust construction, and this requirement is fulfilled by using different types of stainless steel. The following properties of this material are the reasons for using it for these containers:

  • Extremely resistant to chemicals
  • Has a high resistance to corrosion
  • 304L stainless steel has a great weldability
  • Capability of withstanding humid conditions, sunlight, or high temperatures

4. Carbon Steel: Pressure vessel manufacturers uses this material on large scale. Here are the reasons for choosing this material:

  • Capable of retaining strength, even at minimal thicknesses
  • Excellent tensile strength
  • Resists vibrations and shock
  • Can be recycled easily

5. Aluminum: This is yet another material, which is most commonly used in these vessels, for the following set of its properties:

  • Capable of maintaining high tensile strength between 70 and 700 MPa
  • Easier and more cost-effective to machine compared to stainless steel
  • Has a larger coefficient of expansion compared to other metals

6. Hastelloy: If you are going to use pressure vessels in oil and gas, petrochemical, or chemical applications, then this is a well-suited material, for the following reasons:

  • Has a good resistance to corrosion
  • Capability to last for several years
  • Has an excellent resistance to cracking
  • Comes in a wide range of types, such as C276, S, C, B2, and more for use in several applications
