FAQ about Hygienic Piping
Do you provide validation reports and testing?
Yes – documentation and validation are always included in the delivery. We produce the documentation needed for the client to demonstrate compliance to authorities (e.g., Fimea/FDA). This includes material certificates, weld logs, pressure tests, and NDT inspection reports.
Which standards is the execution based on?
We always follow the standards required by the specific project. Typically, hygienic piping follows GMP guidelines (Good Manufacturing Practice) and the ASME BPE standard (BioProcessing Equipment), which define cleanliness classes, materials, and surface quality. Additionally, we operate in accordance with the ISO 3834-2 quality management system for welding.
How do you ensure cleanliness?
The chain of cleanliness must not be broken at any stage.
- Storage & Handling: Pipes and components are kept protected and capped until installation.
- Tools: We use tools intended exclusively for stainless steel to avoid ferrous contamination (rust transfer).
- Surface quality: We ensure that the internal surface roughness (Ra value) of the piping remains at the required level after welding.
Purity cannot just be promised – it must be proven
Hygienic piping is in a league of its own. It is not enough for the work to look good – it must be flawless at a microscopic level.
A single carelessly ground joint can cause production downtime or contamination. That is why at PreOne, purity is not just a goal – it is an absolute requirement. We design and deliver hygienic piping in accordance with GMP standards.
We utilize orbital welding to achieve a completely uniform and oxide-free weld – the kind that even process sensors appreciate. All our materials are acid-proof and polished, and every line of welding data is automatically recorded for documentation.
Our work begins with design and ends with validation. We review process requirements, material selection, and flow geometry with the client to ensure the piping is optimal for both hygiene and efficiency.
The result: a piping system that operates without microbial risks and is audit-ready from the moment of commissioning. And although the subject matter is serious, smiling is not forbidden in our team. In the cleanroom, the jokes are just a little shorter – simply because it’s hard to laugh for long behind a mask.
