Our Piping Engineering group represents a core competency in MegChem’s portfolio of engineering expertise. This group currently consists of some 70 Piping Designers, as well as 16 Piping Engineers, located in Secunda and Sasolburg.

The group’s expertise centers around design and layout of high pressure, high temperature piping, as is typically encountered in the oil and gas, power generation and related industries. Although most of our designs conform to the ASME codes as per client specification, we are capable and experienced in most international codes (e.g. DIN, BS, EN, AS etc.). All our piping designs also conforms to all local regulations and laws, and specifically complies with the newly promulgated Pressure Equipment Regulations (PER) of the OHS Act.

In order to ensure quality and to comply with all standards and client specifications, MegChem has developed a rigorous Quality Management System (Certified to IS0 9001:200). This quality system, together with our highly experienced engineers and designers, enable MegChem to produce engineering designs that may be used with confidence by project managers, clients and construction teams.

A wide range of state-of-the art software is being used; amongst others this includes MicroStation or AutoCAD together with Cadworx for 3D modelling. We are also well experienced in the SmartPlant Suite (3D and P&ID) from Intergraph, and recent projects have shown significant increase in productivity through utilization of this integrative software platform. Integrity of piping and compliance to design codes is ensured by using dedicated piping flexibility analysis software, including Caesar II and AutoPipe.

Although a major part of our work is being performed as part of an integrated multi-disciplinary engineering team under guidance of a project manager, we are also well suited to do piping design work for clients on a single discipline basis, as is typically required by Owner-Operators in maintenance related work or for small design changes on existing plants.

MegChem also has significant expertise in regenerating statutory documentation of existing plants. Amongst others, this documentation includes “as-is” P&ID’s and piping isometric drawings. Over the years, many plant owner-operators find that their statutory documentation becomes outdated, and does not reflect the current status of the plant. In order to regenerate such documentation, MegChem employs high definition laser scanning of the existing plant. 3D modelling of the plant may then be done based on these scanned plant images. 3D modelling may be done either in AutoCAD or SmartPlant, depending of specific client requirements.

Engineering Analysis is the division of MegChem that specializes in using numerical techniques to solve static, dynamic and transient problems in the fields of structural and fluid mechanics. The division consists of qualified engineers specializing in a wide variety of analysis disciplines.

MegChem’s Engineering Analysis team integrates its experience in engineering analysis in the fields of Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD) and experimental analysis to provide engineering solutions to the industry by using state-of-the art computer hardware and software technology.


Common Areas of Application

Detail Design: The experience and tools available to MegChem enables us to perform accurate designs on virtually any equipment or part. Using online measuring techniques, applied loads and temperatures can be accurately determined. In flow applications, Computational Fluid Dynamics (CFD) analysis can be used to quantify pressure and temperature boundary conditions. Using finite element analysis a detail stress distribution can be calculated. Stresses can be evaluated statically or dynamically. Afterwards, online measuring can be used to verify results.

Design Optimisation: By means of computer simulation the duration of design cycles are drastically reduced compared to physical prototypes. In addition to being excellent design tools, FEA and Computational Fluid Dynamics (CFD) can be highly cost-effective when used to optimise a design to reduce cost of manufacture or operation or to increase the operational efficiency. Accurately quantifying operational loads by means of online measuring could also result in a more optimised design by decreasing design safety factors.

Failure Analysis: The cause of failure of a component can often be determined after determining the operational loads and using these as input for a detailed stress analysis. Very often, cyclic loading can be a cause of unexpected failure. MegChem has the ability to perform advanced fatigue analyses on components. Using a combination of online measuring and finite element analysis, a stress history during an operational cycle is obtained. In-house developed software is then used for stress cycle counting and fatigue damage assessment. The method is also used for real-time fatigue damage assessment of components during operation. A fracture mechanics analysis can also be used to determine growth rate and severity of defects.

Problem Tracing: By measuring the boundary conditions and simulating the operation of a part or process by means of FEA or CFD, a good basic understanding of the principles of operation can be formed. This invariably leads to an understanding of problems that are being experienced with the equipment and the formulation of likely solutions. Proposed solutions to the problem can be evaluated with FEA or CFD to reduce the risk of failure to acceptable levels.


The tools

Structural analysis: We use software developed and marketed by MSC.Software (, one of the leading providers of Computer Aided Engineering (CAE) software, most commonly used:

Computational Fluid Dynamics (CFD) Analysis: We use CFX developed by ANSYS Inc. (
