DELIVERY PROGRAM HEAVY PLATE - Dillinger Hütte GTS

XXXXXX Integrated Management System (IMS)
The individual production operations, the subsequent inspections, and their results, are
documented step-by-step in our IT systems, and validated against specified requirements.
The status of implementation of an order is therefore known and traceable at all times.
At Dillinger Hütte GTS, all processes and products are thus subject, from the initial
enquiry up to and including final shipment, to a comprehensive QM system that assures
quality all the way through to handover to the customer.
Certificates and approvals
In addition to the system certificates for the standards and accreditations incorporated
within the IMS, Dillinger Hütte GTS also possesses numerous other certificates and
approvals based on specific codes and standards. These include, for example, approvals
from all known classification societies, such as ABS, BV, DNV, LR, GL, and approval in
accordance with the European Pressure Equipment Directive (97/23/EC).
The Heavy Fabrication Division additionally possesses the ASME S, U and U2 certificates
(stamps) for boilers and pressure vessels.
Quality Assurance
Steels made at Dillinger Hütte GTS are constantly checked for adherence to the characteristics
and properties set down in the respective codes, standards, materials codes and
customer specifications.
Non-destructive testing methods performed on the plate itself during production, and
destructive testing performed in the inspection laboratory on plate samples are available
for inspection purposes. Where no other conditions have been agreed, inspection
of surface quality is performed in accordance with the conditions defined by EN 10163
and checking of geometry and dimensions in accordance with EN 10029.
Ultrasonic inspection
The internal quality of Dillinger Hütte GTS plates, i.e., their freedom from impermissible
material segregations and inclusions, is assessed using ultrasound. Ultrasonic (US)
inspections can be performed manually, using US inspection systems, or on an automat ed
ultrasonic heavy-plate inspection machine. Ultrasonic inspection can be performed in
accordance with German, European and international standards, where specified in the
order; these include:
■ EN 10160
■ ASTM A 435, ASME SA 435
■ ASTM A 578, ASME SA 578
and upon agreement all other standards and customer specifications.
All classes of surface and sub-surface zone, and all combinations of classes, are possible.
The scope of inspection specified in the standard is routinely implemented; other scopes
of inspection for the surface and the sub-surface zone are also possible on request.
The inspection staff are qualified and certified in accordance with SNT TC 1A and/or
EN 473.
