PipeMech Engineering is a South African design office for the oil, gas, petrochemical and chemical industries. Professional engineering registered with ECSA, full 3D design, and an AI-assisted office that drafts, checks and tracks every deliverable before an engineer signs it.
Metallic and non-metallic process equipment, pressure piping and the plant around it. We take feasibility studies, basic and detailed engineering, fabrication drawings and compliance through to the record set, with the same team at every stage.
Pressure vessels, storage tanks, heat exchangers and process equipment, designed to code with datasheets, calculations and fabrication drawings.
Plant layout, 3D piping, isometrics and line classes, with flexibility and stress analysis on every line that needs it.
Categorisation and conformity under SANS 347 and the Pressure Equipment Regulations, and the engineering behind keeping equipment in service.
Everything modelled in 3D before a drawing is cut, clash-checked against the existing plant and extracted as a complete drawing set.
Also: feasibility studies, technology sourcing, structural steel for factories and warehousing, owner's engineer reviews and documentation audits.
We have rebuilt how a design office works. Discipline agents trained on our codes, standards and procedures draft the calculations, datasheets, registers and drawings. The office then checks the work the way a design squad would, and a registered professional engineer reviews and signs what goes out. Clients get first drafts in hours, not weeks, with the same accountability as before.
A vessel, piping, materials, HSE or document-control agent takes the design basis and produces the deliverable in our templates, to the code it names.
Every drawing and calculation is checked against the design basis, the code and the rest of the package before an engineer sees it. Holds are listed, not hidden.
Nothing leaves as anything other than a draft until a professional engineer has reviewed it. Document control then numbers, registers and transmits it to your system.
Every output of the AI office is stamped as a draft for engineer review. It is never issued, certified or signed by software. The professional engineer who signs the Certificate of Design has checked the work, as the Engineering Profession Act and the Pressure Equipment Regulations require.
PipeMech Office is the AI design office as a web app. Sign in with your work email, ask a question or drop a datasheet in, and the right desk answers in our templates, with the code clause it used. Chats and projects are shared with the engineers working on your job, so nothing is lost between a question and the deliverable.
No password. A one-time code is sent to your email through Cloudflare Access.
Chats, attachments and drafts live in projects the whole team can see.
Every answer is stamped for engineer review. The engineer issues and signs.

Prommac.app puts turnaround and project dashboards in front of the whole team: scope, schedule and site readiness updated from the same schedule and scope register the planners use. PipeMech's digital team develops and maintains it for Prommac and its clients.
Access to each board is granted per site, by invitation from Prommac. The same platform can be set up for your plant, turnaround or capital project.
Our work sits in process plants where the equipment is registered, the downtime is expensive and the regulator is involved. That shapes how we design, document and hand over.
Separators, storage, pipelines and the piping between them.
Synfuels and chemicals complexes, brownfield tie-ins and revamps.
Corrosive services in metallic, GRP, FRP and thermoplastic materials.
Air separation and hydrogen plants, turnaround scope and readiness.
Process plant equipment, tanks, structures and piping on site.
Code calculation, stress analysis and 3D plant design, with the model as the single source for every drawing.
PipeMech Engineering (Pty) Ltd is led by Wessel Vosloo, a mechanical engineer registered with the Engineering Council of South Africa, with a drawing office of senior mechanical and piping draughtsmen. Our vision is to be recognised for pioneering engineering of pressure and non-pressure equipment while holding the highest standards of safety, reliability and efficiency.
We work from Vanderbijlpark in Gauteng and on site at our clients' plants in South Africa and abroad, and we build the digital tools our clients and partners use to run their projects.

Risk assessed and planned before it is drawn. Compliance is the floor, not the target.
Quality and precision in the calculation, the drawing and the record set behind them.
Current in the codes and the pressure equipment technology they govern.
New tools adopted when they make the work better, and proven before a client relies on them.
Solutions fit for the plant and the people who run it, built on long relationships.
Transparent, honest and accountable in every commitment, with an engineer's name on the work.
A short description is enough to start. We will come back with questions, a scope and a man-hour estimate.
