Pressure Vessels & Heat Exchangers: wide choice, specific answers

Allteko deliver a wide range of pressure vessels and equipment built to meet individual customer needs for specific project requirements.


Heat Exchangers

We supply a wide range of heat exchangers in a variety of materials including Carbon steel, Stainless Steel, Duplex and Super Duplex. Tube materials again range from Carbon Steel, Stainless Steel through to exotics such as Titanium and Hastelloy.

Our design teams offer the following services:

  • Process calculation (thermal and flow), strength calculation, technical workshop documentation, technical advisory and consulting.
  • Manufacturing accreditations include ASME, TUV, GOST R, UDT, LLOYD’S and SLV.
  • Quality Assurance System ISO 9001:2002.
  • Technical documentation to the following codes and standards: EN13445, WUDT 2003, AD 2000 Code, ASME, TEMA R, C and API 661. Equipment delivered into the EC market corresponds with PED 97/23/EC.

Petrochemicals

Allteko supply shell and tube heat exchangers to the oil, gas and chemical industries.

The equipment conforms to the following design and technological requirements relevant to these industries:

  • ASME
  • PD 5500
  • GOST
  • TEMA
  • Other World standards

Heat exchangers offered by Allteko cover the full range of construction varieties, in single-pass and multi-pass units.

Power Industry

Allteko supply heat exchangers meeting the requirements of the power industry, and high-pressure (HP type) and low-pressure (LP type) equipment is available including:

  • Regenerative Preheaters
  • Heat Exchangers
  • Water Coolers
  • Oil Coolers

Helically baffled exchangers

Helically baffled exchangers are the latest in shell and tube exchanger design configuration, in which baffles are put along the screw line. Each baffle segment occupies about one quadrant of the cross section. Such a construction creates a medium continuous pluq in the intertube space.

HELIXCHANGERS applications include refineries, petrochemical and power industry as well as in the offshore platforms.

Such exchangers are best suited to applications in which the heat transfer coefficient plays a determining role, or where pressure drop or fouling reduction are important.

Compared to the conventional solution, where baffles are placed perpendicularly to the exchanger axis, heat exchangers with helical baffles offer the following advantages:

  • Increased Heat Exchange Rate
  • Reduced Loss of Pressure
  • Reduced Fouling
  • Reduced Frequency of Periodical Surveys
  • Reduced Vibration Hazards
  • Longer Lifetime of Exchanger
  • Relatively Lower Investment Costs
  • Reduced Maintenance Costs

Vessel Process Apparatus

Allteko supply vessel type process equipment, which is designed and manufactured with ASME U-stamp, TÜV and UDT approvals and we supply equipment built to meet individual customer's specifications.

Demisters

In many process operations the removal of entrained material in vapour flows is essential. Allteko provide a wide range of mist eliminator and/or demister units suitable for any application.

The Mist Eliminating products that we are able to provide rely upon the high quality, versatile, knitted mesh threaded with a vast range of materials, typically including:

  • Stainless Steel: Grades AISI 302, 304, 316L, 321, 309, 314, 310S
  • Super Alloys: Inconel 601, Incoloy DS, Hastaloy, Carpenter 20, Monel
  • Fibrous Filament: ‘E’ Glass, ‘S’ Glass, ‘A’ Glass, Basalt, Ceramic, Silica, Kevlar (para-aramid)
  • Others: Aluminium, Copper, Brass, Mild Steel (plain and galvanised), Polypropylene, Hostaflon, Polyethylene, and any other continuous filament material supplied as a wire or yarn
  • Allteko endeavour to meet any size or any other material you may require.

Our team of technical experts are always available to offer advice and to ensure a Heat Exchange, Pressure Vessel, or Mist Eliminating solution can always be found.
