Specialised Alloy Steel Engineering

Teralba Industries’ qualified fabricators work with a range of stainless alloys in the manufacturing process, including the common nickel-based alloys, duplex steels and titanium.

The unique values provided by stainless steel make it a powerful candidate in material selection. It is essentially a low carbon steel which contains chromium, along with additional elements such as nickel, molybdenum, titanium and niobium.

The “stainless” characteristic is obtained by the natural formation of an invisible and adherent chromium-rich oxide surface film that has the ability to heal itself in the presence of oxygen. It is these elements that give it its unique corrosion-resistant properties.

Premium Properties

Along with its corrosion resistance, other benefits of stainless steel include:

  • Strength: Its make-up provides a hardening property that results in a significant strengthening of the material, allowing it to function at and resist high temperatures and those that are far below freezing.
  • Hygienic: Easy to clean, it is the first choice for strict hygiene conditions and requirements. This makes Teralba stainless steel pressure vessels and hydrocyclones ideal for use in critical applications within the food, dairy, beverage, chemical and pharmaceutical industries.
  • Aesthetic Appearance: Its bright and easily-maintained surface provides a modern and attractive appearance.
  • Fire and Heat Resistance: Chromium and nickel alloyed components allow it to resist scaling and the ability to retain its strength at high temperatures.
  • Long Term Value: A long-lasting material and when the total life cycle costs are considered, it is also often the least expensive material option.
  • Ease of Fabrication: Modern manufacturing techniques mean that it can be cut, welded, formed, machined and fabricated as readily as traditional steels.
  • Versatility: It withstands many liquids, chemicals and gases without rusting or discolouring.

Teralba Industries Hydrocyclone

What is a Hydrocyclone?

A hydrocyclone is a static device that applies centrifugal force to a liquid mixture so as to promote the separation of heavy and light components.

The hydrocyclone is a closed vessel designed to convert incoming liquid velocity into rotary motion. It does this by directing inflow tangentially near the top of a vertical cylinder. This spins the entire contents of the cylinder, creating centrifugal force in the liquid. Heavy components move outward toward the wall of the cylinder where they agglomerate and spiral down the wall to the outlet at the bottom of the vessel. Light components move toward the axis of the hydrocyclone where they move up toward the outlet at the top of the vessel.

A hydrocyclone is most often used to separate heavy particulates from a liquid mixture originating at a centrifugal pump or some other continuous source of pressurized liquid. A hydrocyclone is most likely to be the right choice for processes where light particulates are the greater part of the mixture and where the heavy particulates settle fairly easily.

Generally, hydrocyclones are used in continuous flow systems so that the instantaneous liquid inflow to the hydrocyclone is equal to the total instantaneous outflow of light particulates plus heavy particulates. In cases where heavy particulates are a very small part of the whole liquid, it is sometimes advantageous to accumulate them in the bottom of the hydrocyclone for batchwise removal.

Teralba hydrocyclones can be configured for high volume flow situations by setting units in parallel. The stainless steel Teralba hydrocyclone is often utilised in conjunction with other separator technologies to effectively protect this equipment from oversize particle damage.
