Borsig GmbH
high quality, reliability and
optimum technical
that´s what our name stands for


All BORSIG products are synonymous with top quality, reliability and optimum technical implementation. Our products are individually designed according to customer requirements. Therefore the BORSIG Group has complete in-house engineering facilities.

BORSIG Process Heat Exchanger GmbH

BORSIG Process Heat Exchanger GmbH has complete in-house engineering facilities. Thermal layout of heat exchangers and special heat transfer calculations are performed and checked with computer programs developed in-house. For highly complex tasks, the gas flow and heat transfer are calculated by means of three-dimensional CFD models (computational fluid dynamics).

The pressure vessels and heat exchangers are calculated with computer programs developed in-house and commercial software PROBAD or PVElite according to all national and international design standards:

ASME CODE Sections I and VIII (Div.1 & Div.2), ASME B31.1 and B31.3, AD-2000, TRD, EN 13445, PD 5500, CODAP, RTOD, IBR, JIS, Australian Standards, Russian Standards, China SQL and GB 150.

In the case of critical parts, Finite Element Analyses are carried out.


  • Software: ANSYS
  • Modelling in 2-D and 3-D
  • Temperature distribution calculation
  • Stress calculation for mechanical and thermal loads (elastic and elastic-plastic)
  • Classification of stresses in primary, secondary and peak parts 
  • Stress and fatigues evaluation acc. to international design codes
  • Contact simulation
  • Stability analysis
  • Modal analysis (calculation of natural frequencies and mode shapes)

The flexibility of the tube systems, the resulting support loads and forces are calculated by a special software.  


  • Software: ROHR 2
  • Modelling of complex piping systems
  • Stress calculations for mechanical and thermal loads
  • Consideration of wind and seismic loads
  • Valuation of calculated stresses acc. to international piping codes
  • Determination of the support loads
  • Rating of spring hangers and supports

The performances of piping engineering include:

  • Material orders
  • Collision check
  • Flexibility calculations
  • Isometrics for the 3-dimensional bending of tubes
  • Construction and commissioning

BORSIG ZM Compression GmbH

BORSIG ZM Compression GmbH manufactures tailor-made reciprocating and integrally geared centrifugal compressor units. The complete process - from the first calculation to the compressor design and systems engineering, right through to manufacturing, delivery, commissioning and after-sales support - is implemented internally.

We also carry out feasibility studies and verification and  revamp studies. The precise design and modernisation of the parts or components is also part of our portfolio. We can even realise the accurate replication and re-engineering of parts, components and entire compressors.

Our design work complies with the following regulations and standards:

DIN, ISO 8011 and 8012, API 614, 617, 618, 672, API-11P and other API recommendations, NACE regulations, ASME regulations

Our engineers use the following software to ensure the optimum planning, calculation and design of the compressors:

Pro-Engineer (3D), Inventor, COMOS, ANSYS, CONCEPTS NREC, XLROTOR as well as extensive calculation and design programs, most of which are developed in-house and are modified to satisfy the existing regulations and standards

BORSIG Membrane Technology GmbH

The BORSIG Membrane GmbH engineering team comprises experienced, highly qualified engineers and technicians who combine their years of experience with the latest engineering tools and programmes. This begins with process simulation using advanced process simulation software and continues with the construction of individualised equipment resulting in a final 3D model of the system.

Our staff consistently furthers their training making us an up-to-date, competent partner in the areas of process technology, construction, and measurement and control technology, and for specialised topics such as explosion protection.

In addition to the design and supply of complete systems, we also offer our customers individual engineering services for both new and existing systems.

BORSIG Service GmbH

BORSIG Service GmbH provides all customers of the power industry a wide range of engineering services in addition to general services for pressure parts and vessels. We focus on redesign and revision of existing systems and components as per customer requirements and in accordance with applicable current codes and standards.

We offer our expertise to our customers in any event of fault or damage. We inspect affected components, analyse damage symptoms and determine respective causes, including adjacent components. We then develop suggestions for improvement and conversion options.

Our innovative assembly concepts allow us to carry out even extensive disassembly and assembly work. Performing within the shortest possible time, professionally and in compliance with all required safety requirements leads to full customer satisfaction.

Among others, our engineers work in the following areas for the successful implementation of your projects:

Generating 2D and 3D CAD models, strength calculations according to applicable boiler and pressure vessel codes and standards, FEM analysis with ANSYS, pipe static calculations with ROHR 2, thermal calculation of natural and forced circulation steam boiler systems, HD and LP heat exchangers, steam cycle calculation including process and component design, static proof of steel construction for support and mounting.
