All-in-one Manufacturing

SEIKO is using “Solid works” for engineering which includes comprehensive 3D graphics, scale 1:1, collision warning and weight calculation.


Over 1500 tons ASME & EN materials are available in stock, including pipes, flanges & solid bars up to 24” for fast deliveries.


Mechanical fabrication is done with a wide range of CNC machinery including saws, plasma cutting, lathes & special lathes and milling machines.


Our welding department is qualified to EN and ASME standards and holds an impressive number of personal welding performance and welding procedure certifications.

Post weld heat treatment for meterruns up to 10m length can be done in our electrical heated temperature controlled ovens.

All non destructive tests can be done in-house including positive material identification (PMI).

Pressure tests up to 700 bar will be executed in the new pressure test rig for flow elements and pipes for a length of max. 10,5m.

Surface preparation and conservation of equipment for corrosion protection e.g. by application of paint or preservative oils and other rust inhibitors.

In our final assembly meterruns are mounted together with shut off valves for tappings, cleaned and prepared for packing.
