Quality Assurance

Excellence in quality testing and assurance is a hallmark of the tubular production at OSTP.


OSTP is approved according to PED 2014/68/EU, demonstrating that our quality systems are suitable for the manufacturing of pressure equipment components and for manufacturing components.

Our EHSQ Management Systems are certified by TÜV NORD CERT in accordance with the ISO 9001 (Quality), ISO 14001 (Environment) and EN ISO 45001 (Health & Safety) Standards.

OSTP is certified according to AD2000-W0 by TÜV NORD Systems GmbH and is also approved by most of the common notified bodies.




The production units of OSTP use a wide range of up-to-date inspection and testing techniques, both in production and during final inspection.

All tests are carried out on calibrated and certified equipment and our non-destructive testing (NDT-) operators are qualified and certified according to international standards.

In addition to the recognised international tests, we are able to carry customer-specific test requirements, by agreement.
