Quality
from start to finish
We demand top quality andoutstanding service from our-selves and our suppliers withthe aim of keeping our custo-mers satisfied in every respect.When selecting our suppliers,we take particular care to en-sure that they are flexible anddependable.
Key to partnering us is the abi-lity to meet the most exactingquality requirements. But even after we have madeour selection, we constantlycheck on the efficiency andquality of our suppliers.
And we apply these same highquality standards to our ownoperations.
Continuous quality control fromincoming goods to storage tooutgoing goods is a matter ofcourse. Our established qualityassurance procedures guaran-tee our customers the depend-ability they have come toexpect from us.
Our EN ISO 9001 quality
management system has beencertified by an internationallyaccredited inspection companyand is subjected to regularinternal and external audits.
The right product for everyrequirement
To ensure that every seamlessor welded steel pipe/tube
meets the requirements placedon it, selecting the right materialquality for the job is essential.Each material has its own spe-cific properties that make itparticularly suitable for itsintended use.
The various materials havebeen classified in groups in linewith their general applicationareas.
In the following, we present theindividual product groups withthe applicable standards andindicate the materials allocatedto each type of pipe/tube.

Our special service
Processing at a glance
We not only supply the gradesand dimensions of your choice,we also ensure rapid and flexibledeployment on site with ourbroad processing offering. Thishelps you save time and
money as time-consuming pre-paration work on site is elimi-nated. The pipes/tubes aredelivered ready-cut for yourproject and can be immediatelyinstalled at the constructionsite.
Cutting
Our cutting center is designedto meet any requirement. Wecut fixed lengths in many differ-ent dimensions up to 850 mmoutside diameter (OD). We canalso produce miter cuts andspecial end shapes in accor-dance with your specificationsand bills of materials.
Weld seam preparation Our comprehensive servicesalso include weld seam prepa-ration.
With our profile milling
machines we can produce adiverse range of joint geome-tries in all dimensions in accor-dance with customer wishes.Even the beveling of miter cutsis no problem for us.
In this way we create the prere-quisites for good and securejoints.
Preserving
Following preliminary treat-ment, the material is blastedwith grade SA 1, 2, 21/2 and 3steel grit in accordance withDIN 55928 Part 4. We thencoat the material either with ashop primer for short-term corrosion protection or with acoating material suitable for
long-term corrosion protection.A further temporary corrosionprotection option for steelpipes/tubes is oiling.
Tube flame-cutting machineThis machine enables a widevariety of processing optionsfor pipe/tube ends and the cut-ting of holes in round
pipes/tubes. We can solve con-tour problems with the tubeflame-cutting machine: Contours are possible forpipes/tubes with outside dia-meters of 30 to 800 mm, wallthicknesses of 3 to 100 mm and pipe/tube lengths of 300to 14,000 mm.
Grinding
On request we can carry outsurface grinding in particular ofprecision steel pipes/tubes. Thechoice of grain is based on therequired surface fineness forthe pipes/tubes.

Material testing/Inspection certificates
Material testing
We can carry out all commontests for you. These include:· Non-destructive testing, e.g. ultrasound tests and surface crack tests.· Destructive testing, e.g. chemical analyses, tear tests, hardness tests, notched bar impact tests.· Technological testing,
e.g. flattening tests, bending tests, ring flaring tests, drift expanding tests and flanging tests.
We work together with yourinspectors or the inspectioncompanies specified by you,e.g. the German TechnicalInspection Agency (TÜV),Lloyd’s Register of Shipping(LRS), Det Norske Veritas(DNV), Germanischer Lloyd(GL), Bureau Veritas (BV),American Bureau of Shipping(ABS).
Certification in accordancewith EN 10204
We offer our customers certi-fied safety. On request, yourdelivery can be made with thecertification you require inaccordance with EN 10204.Please define the type of certi-fication when placing the order. The various certifications inaccordance with the latest edition of EN 10204 (January2005 version) are listed in theabove table.
