Industrial piping for the pharmaceutical industry

Industrial piping for pharma and biotech: hygienic, documented, traceable.

For pharma and biotech plants in the Basel region we build stainless steel lines in which every weld, every heat and every spool can be traced. Prefabrication in Pratteln, installation in the shutdown window, documentation according to your form.

What pharma plants get from us

01

Process lines in stainless steel 1.4404 (316L) for product, solvents and cleaning media.

02

Utilities supply

ultrapure water, pure steam, compressed air, nitrogen, cooling and heating media.

03

Waste and exhaust air lines in stainless steel, Hastelloy or PTFE-lined, depending on the medium.

04

Stainless steel equipment

work tables, racks, pipe supports from our metalwork shop.

05

Modification and maintenance of existing plants for product changeovers or extensions.

Hygienically welded stainless steel lines

Hygiene and traceability

Pharma lines are welded by the TIG and orbital processes, with root shielding, so that the inside stays smooth and free of oxide. Where required, we inspect the root by borescope and document it photographically. After welding, the welds are pickled and passivated.

Every spool is given a number. Through it, the material certificate, welder, weld log and test result can be traced. You define on our form, when ordering, which documents you receive at the end, in line with your internal quality requirements.

Working on pharma sites

Our staff know the access, hygiene and safety rules of the pharma sites in the Basel region and complete the site-specific training before work begins. We plan the work so that your shutdown window is kept and areas in operation are not affected.

Step by step

How we work

  1. Step 01

    Clarification

    medium, hygiene class, surface requirement, scope of documentation.

  2. Step 02

    Design

    isometrics, bill of materials, inspection and test plan.

  3. Step 03

    Prefabrication in Pratteln

    welding, testing, pickling and marking the spools.

  4. Step 04

    Installation

    in the shutdown window, with minimal presence in the production area.

  5. Step 05

    Testing and documentation

    pressure test or leak test, handover of the documentation package.

FAQ

Frequently asked questions

Can you prove the origin of the materials?

Yes. On request we supply material certificates to EN 10204 (3.1 or 3.2) and assign spool numbers, so that every pipe section can be traced to its heat, welder and test result. You define the scope when ordering.

How do you keep the downtime of our plant short?

Through prefabrication in our workshop in Pratteln and installation planning that is coordinated with your shutdown window. From Pratteln, our fitters are on your site quickly.

Do you comply with our site regulations and safety rules?

Yes. Our staff have been working on chemical and pharma sites in the Basel region for years and are familiar with access, safety and hygiene requirements. We complete site-specific training before work begins.

Which lines do you build for pharma plants?

Process lines, utilities supply (ultrapure water, steam, compressed air, cooling and heating media) and waste lines in stainless steel, plus pipe supports, walkways and frames from our metalwork shop.
