3 Top Sectors to Use Structural Steel Plate

December 14, 2021

The production and subsequent processing of the structural steel plate represent two fundamental phases. Plates can be made of many materials, with a preference for stainless steel. Let's find out more about stainless steel plates.

Structural Steel Plate

For quality structural steel plate which material to choose?

A careful choice of materials for the production of the tubes is essential. To obtain high-level products, therefore, it is essential to prefer a certified stainless steel such as AISI 316.

The AISI - American Iron and Steel Institute, in fact, represents one of the famous and most reliable producer associations for the control of stainless steel.

The structural steel plate prepared in different formats (rectangular or circular section) and in different sizes and lengths.

Why choose certified steel?

Certified stainless steel is ideal for applications where there is a risk of corrosion, such as swimming pools, coastal areas or particularly polluted areas. It is also useful in industrial sectors such as:

  • firstly, chemist
  • secondly, petrochemical
  • Thirdly, food
  • fourthly, pharmaceutical

Furthermore, it is also useful in different contexts such as paper mill production, in the extractive industries and in refineries. And even in nuclear plants.

Stainless structural steel plate: processing and checks.

Given the importance of their functions, stainless structural steel plate subjected to meticulous checks. Furthermore, after production, they are in the need to special processes such as:

  • pickling
  • satin finish
  • scordonatura of the welds

Are you looking for stainless structural steel plate? 

On our site you can find them. One of the countless applications of steel is in the petrochemical (or oil) industry. In fact, in the plants, during the oil or natural gas refining processes, it is necessary to use extremely resistant equipment.

Why the choice of structural steel plate?

Given its multiple properties, steel is one of the materials for structural steel plate with the greatest potential for use.

As mentioned earlier, the petrochemical industry also uses steel in its plants. In practice, petrochemicals produce the starting materials for the production of drugs, dyes, plastics, detergents and much more.

Today, however, the uses of steel have become many: from infrastructures to civil buildings. Let's see together some of the fundamental characteristics of steel:

  • Deformability
  • Good thermal conductivity
  • Hardness
  • Good resistance to
  • tensile failure
  • enervation
  • corrosion (in the case of stainless steels)

Structural steel plate and the petrochemical industry

The conditions of use of steel in the petrochemical industry and for structural steel plate are extremely demanding. This is precisely due to the aggressiveness of the treated fluids and the high operating temperatures.

In the production of the acid, for example, temperatures of 500 ° C are reached. Another case is that of the reactors used for the production of urea, where temperatures of 200 ° C are reached, at a pressure of 240 atm.

Which type of steel to use for structural steel plate?

The most used steel in this sector is stainless steel. Obviously, the choice will be there according to the characteristics necessary for the condition of use. A few examples of Steels:

  • austenitic (if generic corrosion resistance is required)
  • ferritics with a high chromium content (suitable for withstanding highly oxidizing media, in the presence of high temperatures, with limited stresses)
  • martensitics or nitrogen-reinforced austenitics

The production and processing of structural steel plate obtained from sheet metal represent the main activities. It offers a series of large-sized items ideal for satisfying every need in a market that increasingly requires steel.

Why this material is used?

This material, in fact, has characteristics of considerable flexibility. In the sense that it is easy to work with, and at the same time guarantees a long resistance over time.

The structural steel plate obtained from sheet metal, round or square according to customer requests, need to make according to a production process in several stages which includes, among other things:

  • cutting
  • calendering
  • the bevel
  • the finishing of the ends
  • welding (both internal and external)
  • visual and dimensional checks.

What are the common tests for safety purpose?

In fact, to guarantee the safety of this large structural steel plate, specific, non-destructive tests and tests are necessary, such as x-rays and ultrasounds, but also magnetic powders. Often, then, the hydraulic pressure seal test is used.

Among the various tests available, there is also the use of penetrating liquids and eddy currents. Moreover, the leakage currents, in fact, can be exploited for non-destructive tests in order to identify the presence of defects in this kind of structures.

It is evident that all these procedures are not complete without cutting- edge technological equipment. Moreover, with high-level machinery and tools that makes it possible to make the automated manufacturing process safe and stable.

How to obtain the quality the plates?

Furthermore, the quality of the structural steel plate obtained from sheet metal.  It guaranteed a series of certifications (Aisi) by recognized bodies and institutes, which certify their reliability.

Where these plates are applicable?

The plates obtained from sheet metal can be useful in many different contexts, especially in the industrial field:

  • they can therefore be there in companies and plants that deal with energy or chemistry,
  • also in the paper processing industries
  • in companies of mining
  • refineries,
  • nuclear plants
  • even in the agricultural sector

How to produce these structural steel plates?

The production and processing of large diameter plates carried out according to different procedures. It depends on the final destination of the products. In particular, square structural steel plate can be created by:

  • Welding
  • hot rolling

The welding, in turn, can be of different types:

  • electric resistance
  • in submerged arc
  • in submerged helical arc
  • or longitudinal

What we provide to our customers?

We deal with the production of large diameter square and circular section plates. They are useful in numerous fields:

  • from the agricultural sector to the energy sector
  • from the pharmaceutical sector to the chemical sector
  • therefore it is useful in a wide variety of contexts

Also of considerable importance: large steel pipes, in fact, represent a fundamental component of nuclear plants, extraction companies and refineries.

Following production, large structural steel plate is the subject to one processing or several successive processes: satin finishing, polishing, pickling, welding detuning and passivation, just to name the most common.

What are the steps in production process?

The production processes are quite elaborate, and involve numerous stages in succession: among others, it is worth mentioning the

  • caulking of the sheet metal edges, which allows the edges to be ready for welding,
  • the shaping of the barrel, which must give life to a cylindrical shape,
  • the various welds, both internal and external, with different machinery depending on the type
  • Once completed, the weld provide test through an ultrasonic check, which aims to check for any defects or imperfections.
  • X-ray check, in turn useful to identify any corrections.
  • Finally, some specific magnetic powders are there. After the hydraulic seal test, are useful to verify that every detail of the large diameter pipes is perfect.
