DETAILED INFORMATION

Our company is relatively engaged in manufacturing and offering a wide range of industrial products, and today we are offering the finest quality of Alloy 20 Pipes & Tubes that is available in full range. Due to this, we are able to provide our clients with various specifications, dimensions, sizes, types, shapes, lengths, ends, etc., as well as custom sizes and dimensions based on the product drawings we receive from our clients. The product is designed using the premium quality of Alloy 20 alloy, also called Carpenter 20 alloy. When designing it, we also take several industrial standards into consideration, including ASTM, ASME, and API.

An austenitic alloy containing chrome, nickel, and iron is alloy 20. It was developed to enhance the resistance to acid attack, mainly sulfuric acid. In addition to its excellent general corrosion resistance, this alloy is also resistant to crevice corrosion and pitting in chemical-containing atmospheres. In addition, it contains niobium for stabilization against sensitization, as well as resistance to phosphoric acid and nitric acid. Pipes and tubes of these types come in different sizes and shapes.

Moreover, alloy 20 possesses excellent corrosion resistance along with very high mechanical properties and is designed for use in sulfuric acid-related engineering fields. It has now become the ideal alloy choice for many industries worldwide.

Since Alloy 20 Pipes & Tubes have many good properties, they are recommended for use in typical industrial applications due to their excellent corrosion resistance. As well as good corrosion resistance to sulfuric acid and chloride stress corrosion cracking, it has excellent mechanical and fabricability properties.

There are many industrial applications for Toady Alloy 20 Pipes & Tubes, such as food processing, constructions, chemical industries, petrochemicals, pharmaceuticals, offshore oil drilling, power generation, pulp & paper industries, condensers, heat exchangers, and more.

Pipes and tubes made of alloy 20 are dispatched from our industry only after they have been thoroughly tested and certified. The tests include material identification, pitting corrosion tests, toughness tests, etc.

Alloy 31 Pipes & Tubes packaging-

In order to ensure quality, packaging units, including pallets, wooden packs, and eco-friendly bags for sheets and plates, must be carefully considered.

Applications of Alloy 31 Pipes & Tubes

Typical fields of application for Alloy 31 Pipes & Tubes are:

  • Plant components for flue gas desulfurization (FGD)
  • The wet digestion process is used to produce phosphoric acid
  • Sulfuric acid pipes and heat exchangers contaminated with chlorides
  • Condensers, chillers, and pipes containing ocean and brackish water
  • A sulfuric acid pickling plant as well as a nitric-hydrofluoric acid pickling plant
  • Using waste sulfuric acids for treatment
  • Salt crystallization and evaporation
  • Components for the cellulose and paper industries
  • For the digestion of laterite ores, HIPAL (high-pressure acid leach) plants are used
  • Production and refinement of mineral oil
  • Synthesis of organic acids and esters
  • Chemicals of fine quality
  • Oil and gas transport pipes, slicklines, wirelines, and flowlines that are strain-hardened
  • Diesel scrubber for marine use / marine scrubber for ships
  • Tubes for waste to energy that are longitudinally welded

Test and test certificates-

A rigorous quality control process takes place at Mehta Metals.com during the manufacturing process for all of our materials. Spectroscopy, positive material identification, mechanical testing, tensile testing, micro- and macro-testing, pitting resistance testing, and flaring testing are some of the methods used to test sheets and plates. There are three special tests performed: intergranular corrosion, flattening, and third-party inspection.A rigorous quality control process takes place at Mehta Metals.com during the manufacturing process for all of our materials.
