Marking for Oil & Gas Equipment


Manufacturers and suppliers of oilfield equipment are regulated by various organizations including American Petroleum Institute (API), American Gas Association (AGA), International (ISO/IEC), and European standards (CEN/CENELEC). Regulations for these manufacturers and suppliers depend on the type of equipment, where it will be used, and the purpose it will be used for. 

As discussed, GT SCHMIDT designs and supplies marking equipment to Oil & Gas manufacturers. Our machines for this industry include integration heads, portable hand-held devices, and laser marking machines that are able to mark automatic date codes, sequential serial numbers, manufacturing codes, part numbers, logos, and more. For more information on how our machines can assist with your Oil & Gas needs, call to speak to a member of our team today.

Marking on Oil Field and Natural Gas Equipment


  • Instrument tag number 
  • P&ID number
  • Fluid name and nature of fluid
  • Process flow diagrams
  • Pressure and temperature
  • Valve specific requirements
  • Name and date of manufacture
  • Serial numbers and loop numbers
  • Electrical, hydraulic, pneumatic signals
  • Logos, graphics, or any custom marks


Given the extreme temperatures, high pressures, and demanding operating conditions oil field components endure, the tracking identification marks must be permanent and able to withstand harsh environments. Many of these oilfield components also have to pass corrosion and re-certification tests during their lifetime of usage. GT SCHMIDT's laser marking and pin marking machines offer the depth of mark and permanency required to comply with these tough standards and regulations.

  • Tracking and traceability of components
  • Depth of mark and permanency Required
  • Improved processes and quality control
  • Clear specification of workflow process
  • Proof of performance and compliance
  • Tracking for analysis reports
  • Re-certification and inspection approval  


Due to the sensitive usage, product specification requirements must be marked on all oilfield components including, rotary drilling equipment, pumping units, downhole equipment, drilling production equipment, gas pipelines, and more.  Oilfield equipment product specification information is key to tracking the equipment from the time it is manufactured through the life of the parts.
