Implementation cryogenic projects

At the client's facilities and production sites, the company carries out project engineering and technical equipment for gasification or liquid phase supply with air separation products (oxygen, argon, nitrogen, air) and welding mixtures, corresponding to certain technical characteristics:

  • required pressure,
  • required temperature,
  • required flow,
  • Required percentage of the components of the mixture

Other technical characteristics of equipment and installations: 

  • the presence of telemetry, 
  • pressure and flow measurement, 
  • smoothing consumption peaks,
  • others, depending on the wishes and needs of the customer. 

The full cycle of engineering support of the company includes works that the company provides and accompanies until the equipment is functioning properly at the client’s production site, namely:

The entire scope of work included in the period of time between pre-contractual negotiations and the transfer of serviceable equipment into operation to the client.

Site Inspection

Visiting the client's site and checking the possibility of installing equipment, taking into account the following requirements:

Customer sites

  • Transport accessibility for a cryogenic semi-trailer (delivery, the ability to turn around on the site, the ability to drive to the drain point),
  • The possibility of installing equipment on site, taking into account the distance to engineering networks and communications (sewerage, natural gas, water supply, buildings)
  • Possibility of laying pipelines from cryogenic tanks to consumption points
  • No other obstacles to construction
  • Preliminary negotiations with the client
  • Verification of customer's existing equipment to ensure refueling in accordance with Air Products requirements
  • Modernization of the client's existing equipment to provide refueling in accordance with the requirements of Air Products

Contractor sites

  • Checking the ability of contractors to fulfill contractual obligations to the client
  • Checking the availability of premises, production facilities, certified personnel, engineering services

Engineering calculations and drawings

The company carries out the whole range of engineering calculations and makes sketches and drawings for the installation of equipment, prepares and sends technical specifications to the customer's procurement service, equipment suppliers. We are also engaged in budget planning and carefully monitor the project budget at each stage of implementation.


  • Dimensions of cryogenic tanks to meet the needs of the client with the product and the possibility of filling the tanks, taking into account the limitations of logistics and remoteness from the production site
  • Standard sizes of production evaporators to ensure the required amount of product, avoid freezing in winter
  • Pressure boosting units and pressure boosting evaporators,
  • Safety valves to protect the pipeline of installations and to protect the pipeline of the customer
  • Safety temperature devices,
  • Pressure drops on the way of the product to the customer,
  • Pumps for increasing and maintaining pressure on the customer's side,
  • Other more rare calculations not included in the list, but related to the specifics of the implementation of a particular gasification installation
  • Compliance of the above calculations with standards and requirements


  • Placement of equipment at the client's site,
  • Installation P&ID,
  • In some cases, an isometric diagram
  • Compliance of the above sketches with standards and requirements

Terms of Reference

  • Development of documentation for technical re-equipment,

  • Production of pressure boosting evaporators,
  • Procurement of pressure regulators, temperature protection units, flow meters,
  • Production of automation and control cabinets,
  • Carrying out geological surveys,
  • Foundation and civil works,
  • Installation of equipment on the site,
  • Welding, x-ray, pressure testing,

budget planning

  • Calculation of the cost of performing the entire cycle of work and the purchase of equipment,
  • Calculation of a reasonable safety stock, taking into account possible risks,
  • Keeping track of project budgets
  • Notification of the owner of the budget in case of deviation from the implementation of the budget for one reason or another

We are close at every stage of work

At each stage of the work, we accompany the client, consult and give recommendations on various aspects of the work on the current project, including the stage of putting the equipment into operation and commissioning:


  • Conducting technical negotiations with contractors, agreeing on changes, sending initial data
  • Monitoring on a regular basis the timing of work by contractors (checking at several stages of equipment production the possibility of producing equipment on time)
  • Checking technical documentation at the design stage, sending comments and correcting incorrect sections
  • Collection and transfer of the necessary documentation and information to the regional bodies of Rostekhnadzor, re-sending documents, correction of comments on the list of documents RTN
  • Coordination of the terms of dispatch of equipment, coordination of acceptance of equipment, arrival at the site for unloading and acceptance of overall equipment in critical cases, loading and dispatch of equipment in critical cases
  • Arrival at the supplier's production site at the final stage of production (in the case of cryogenic tanks). Acceptance and quality control of work performance
  • Writing claims and return of defective equipment or equipment produced with inadequate quality


  • Maintenance of installation works
  • Acceptance of installed equipment at the client's site
  • Start-up and adjustment works in the process of equipment commissioning
  • Negotiations, correction of comments, customer support during the warranty period of equipment operation
