Steam Generator

Apex , Well Testing has developed its own set of fabrication specifications to ensure that equipment used by Apex Petroleum Services, Well Testing meets or exceeds all local requirements. Apex Petroleum Services, Well Testing specifications are primarily based on the following worldwide recognised specifications:

Equipment Design and Fabrication Specifications

  • API Spec 6A – Specification for Valves and Wellhead Equipment
  • ASME VIII For construction of pressure vessels , Div 1&2
  • API RP 14C – Recommended Practice for Analysis, Design, Installation, and Testing of Basic Surface Safety Systems on Offshore Production Platforms
  • NACE MR-01-75
  • Product Specification Level (PSL) 3
  • Material Class DD
  • Temperature Class P&X (-20° F to +350° F)

Steam Generator

Steam Generators are used to supply steam to parts of the surface test package such as Steam Heat Exchanger, Tank heating coils, etc.
The steam is used to heat the process fluid to raise fluid temperature, aid separation, and prevent the formation of hydrates. The process fluid is passed through coils or tubes, and the steam is passed around the outer surface of the coils or tubes. The heat is transferred through the surface area of metal exposed to the steam. The larger the surface area contact between the steam and the process fluid, the greater the heat transfer.
The steam condenses in the equipment, and the hot water can be returned to the steam generator or discharged.
The steam generator is connected to the equipment via high-temperature rubber hoses. The steam inlet to the equipment is also fitted with double check valves to prevent flow back of hydrocarbons in the event of coil rupture in the equipment.
The steam generators can be either ‘Safe Area’ or ‘Zoned’ units, giving flexibility to either position them away from the well test equipment or have it sited in the test area.

Features and Benefits


• Use of multiple units allows flexibility in the system
• Units can be built into skids for ease of transportation and handling
• Available in various sizes and configurations
