Safe transport routes for liquids and gases

The demands regarding modern pipes are constantly increasing. Pipelines in extreme sea depth require robust and safe pipes. The future use of gas pipelines as pressure tanks requires larger diameters, thicker walls and the use of high-strength steels.

In order to maintain technological leadership in such an environment, pipe manufacturers must consistently optimise their joining processes and put them to the test from time to time. It is a good thing to have a partner who has profound know-how of almost all welding processes and extensive experience in pipeline construction.

Optimising joining processes

Sometimes just a few modifications to the welding parameters and the monitoring of the welding process are sufficient to increase process reliability. This is particularly important in pipeline construction, because defective joining processes often lead to expensive reworking measures or even complaints.

We have the necessary experience to systematically analyse and optimise the joining processes used in pipeline construction. Significant improvements can be achieved in both the longitudinal and radial weld seams.

Introducing new procedures

Optimising the previous welding process will not always lead to the intended objective. We then check whether another joining process is suitable for the steels to be joined and whether the process fulfills your requirements for economic efficiency and process reliability. We provide specific proposals for the selection of the joining process and support the pre-investment phase for new systems. We then accompany you during the implementation of the joining process in your production.

Joining nickel-based alloys

Because of their excellent resistance to corrosion and high temperature, nickel-based alloys are increasingly being used in pipeline construction for power stations or in the chemical industry. When welding these alloys, the challenge is to avoid hot crack formation in these materials and to deliver pipes for the most demanding tasks without defects.

For this purpose, for example, we offer a submerged arc cold wire process developed at the ISF which is suitable for welding nickel-based alloys in several layers without hot cracking.

Finding individual solutions

Every joining task is different. Pipes have to fulfill various requirements depending on the application, which also has an effect on the welding process.

That is why we approach each task individually. We analyse systematically, carry out tests and, subsequently, derive measures thereof. Afterwards, we assist you in introducing new parameters or processes into your production.

Our aim is not only to introduce a perfectly coordinated process into your production. When working together, we always transfer know-how to your staff and thereby increase their comprehension of the processes. This will enable your staff to adapt the applied process to the task of your next project.
