Tests, acceptance and approval

We ensure the full traceability of all protective tubesfrom our company, via batch and serial numbers, as well as drawing and article number.
Postmarking certificates as well as supporting documents for tests and material proofing are part of our standard documentation.


We perform the following tests:

■ Hydrostatic pressure tests up to 1000 bar internal + external pressure testing
■ Ultrasonic examination (UT testing)
■ PT (FE) test (color penetration testing)
■ Magnetic powder test (MT testing)
■ Leak testing (LT testing helium / leak testing)
■ X-ray examination / transmission test (RT test / X-Ray)
■ PMI (Positive Material Identification) testing (Material Interchange Test)
■ Visual examination / endoscopy (VT examination)
■ Hardness test according to Brinell, Vickers or Rockwell


We are certified for:

■ QM system acc. EN ISO 9001
■ Welding compartment operation acc. EN 729-1
■ Pressure equipment approval acc. DGRL AD 2000 HP0
■ Manufacturer approval acc. DGRL Cat .: II – Module A2
■ Weighing technology approval acc. DIN 2303
■ Transfer authorization according to EN 10204 3.1
■ ASME Code Section VIII Div. 1 / U – Stamp – currently still in the auditing phase *


The following certificates can be obtained from us:

■ WAZ EN 10204 3.1
■ WAZ EN 10204 3.2 (TÜV / Lloyds, LRS, Germanischer Lloyds etc.)
■ Restamping certificate
■ Pressure test certificate acc. EN or ASME
■ X-ray reports acc. EN or ASME
■ Certificates acc. NACE MR0175, etc.
■ Test certificates on all the test methods referred to
■ Certificates / documentation on WPS, WPQR, WPQS, etc.




* The auditing and approval of the ASME (American Society of Mechanical Engineers) acc. Section VIII, Div. 1, 2 and 3 has been proposed and planned for September 2017. After successful completion, we then, as one of very few manufacturers, have the right to design and manufacture pressure vessels and pressure-conducting pipeline parts according to this standard, and to stamp them with the corresponding U-stamp: U or U2.
