DESIGN AND DOCUMENTATION

DESIGN

You provide the idea, we do all that is needed to make it reality!

Design and development – the link between sales and manufacturing – are among the ISO-9001 certified functions carried out by our company.

In our company these activities also include preparation of:

• Drawings

• Calculations

• Parts lists

• Risk assessments regarding machine safety

• Operating instructions

We carry out design of your products in-house or in conjunction with expert engineering consultants in accordance with the circumstances at hand.

Utilising all required resources and know-how, we realise optimum technical solutions which are custom-designed to your specific project requirements.

DOCUMENTATION

We carry out comprehensive documentation for all manufacturing operations:

• Pipe systems

• Machine systems

• Auxiliary / mounting structures

You receive all important documentation for your products including:

• Material certificates

• Welding seam lists, test methods and reports

• Certificates and certifications

• Shipping documents

Manufacturing and shipping documentation are

provided separately wherever possible for the sake

of clarity and convenience.

The Benefits We maintain and provide documentation beyond the extent required by legal regulations.


This reflects the high quality of the products we supply, keeps pace with ever-stricter operational safety legislation and provides other advantages as well:

• Accelerated inspections by approval agencies and third-party supervisory organisations (TÜV, DNV GL Group, etc.)

• Potential for reduced insurance premiums

WELDING

We are certified welding specialists for black steel and stainless steel in compliance with a wide variety of national and international standards

and codes. Our compliance is assessed and confirmed by independent supervisory

agencies including DNV GL and TÜV.


Our capability to satisfy your exacting requirements is documented by our certifications to :

• AD2000HP0

• Pressure Equipment Directive 97/23/EC, Category II, Module A

• DIN EN ISO 3834-3

• EN 1090-2

and other codes as well.

All of our welders have - as a matter of course - valid test certification for the welding processes carried out. Our welders regularly take part in continuing education courses which keep them updated on state-of-the-art technologies and procedures. 

Our fabrication facility is divided in two separate processing buildings, one for non-stainless and one for stainless steel.
This prevents airborne particle contamination, ensuring 100 % material purity at all times.
