A- GENERAL TECHNİCAL DATA
1- Quality certifications:
1.1 Tanks have been designed according to AD-MERKBLATT (AD 2000 CODE) and in
case of request; according to ASME .Design calculations and projects have been
inspected and approved by BUREAU VERITAS.
1.2 Our manufacturers has the quality system certification “ISO 9001:2000” as
well as the “CE” and “Π” marking. The third part inspections for all of our
products are done by BUREAU VERITAS.
2- General material quality and the tests:
2.1 The material that will be used in production has been described in the
design. This material is stainless steel which is suitable for using at pressure
vessels in cold service. The material for the shell and heads are defined below:
P 355 GH ( EN 10028-2 )
S 355 J2G3 ( DIN EN 10025 )
P 355 NH ( EN 10028-3 ),
EN 1.4307 (304 L) (EN 10028-3) (For cryogenic tanks)
P440 NJ4
P460NJ2
Selection of this material has been approved with the design and is in
accordance with German DIN and AD 2000 CODE.
2.2 Material purchases are being performed with manufacturer certificates as per
the requirements of 3.1 C. Product numbers are cold stamped on the material and
prior to processing both the production numbers and the certificates are
controlled by the BUREAU VERITAS.
The tests of the tanks are done in our factory by the BUREAU VERITAS. After the
montage onsite, the second test is not being carried out by our company.
3- Fabrication
3.1 Shell plates are being processed by the pre-rolled rolling machine. Special
tools are being used in order to obtain perfect fitting of the heads, so that
circumference is guaranteed.
3.2 Below 10 m³ tanks, head diameters are standardized in between 1000, 1200 and
1600
mm. Heads have been formed in sensitive double effect press equipment and have
been heat treated, so that all heads are standardized, by been produced at the
same dimensions and with regular thickness. Tanks above 10 m3 have the diameters
of 2200 mm to 3500 mm which are produced via special methods and the total
tension is eliminated in special ovens by heat treatment. Page 1
3.4 Welders and welding operators have been tested and certified by the BUREAU
VERITAS.
3.5 Welding procedures, welding wire, and flux have been inspected and approved
by the BUREAU VERITAS.
3.6 After the fabrication and hydro-test, the tanks surfaces are being cleaned
at least
SA 2 ½ surface cleaning standards.
3.7 Surface protection for the above ground tanks up to 10.000 lt, is being done
by means of 40 micron zinc injection and 80 micron of white final coat. All
underground tanks are being coated by means of TAR-U-POX (DYO or equivalent) or
COALTAR EPOXY (MARSHALL or equivalent) with total film thickness is 400 micron.
3.7 The production, documentation and the tests of tanks are being inspected and
certified by BUREAU VERITAS.
