Production and Quality Control

Starting from Zero The different market requirements for material quality standards according to ASME®, ASTM® and various European specifications are allready taken into account when the stainless steel is ordered from the steelworks. The material is cut from the original bar into work-pieces before being used to produce valve bodies. The heat number from the original bar is transferred directly to the valve body or recorded with the batch numbers that are engraved on the valve body. This provides full traceability back to the mill certificate for each single unit.

Computerized, Uniform Handling

The bodies are turned in computer-programmed turning lathes to their final shape and the pipes are welded using semi-automatic TIG welding on the outside. This operation guarantees uniform handling and an outstanding result. The valve part is polished manually and, if required, electro-polished according to your requirements to a surface finish of Ra < 0.5 μm, or better. The Millipore quality control program for the valve body is extensive and ensures that only high-quality products are shipped to our customers.
