Scope of application

This technical code applies to the welding of panels made of high-density polyethylene (PE-HD) for the sealing of concrete structures in the field of ground water protection and for corrosion protection.

In detail, this technical code deals with sealing measures for the following areas of application:

- installations for the storage, filling, manufacture and treatment of water-endangering substances as well as installations for the use of water-endangering substances in the industrial sector and in the field of public facilities (Paragraph 1, Section 19g of the Water Resources Act)

- installations for the transfer of water-endangering substances (Paragraph 2, Section 19g of the Water Resources Act)

- installations for the transport, storage and treatment of waste water and of contaminated seepage water

- installations for the storage of strongly oxidizing media

This technical code is intended to give the responsible authorities, the customers, the executing companies and the responsible people in the quality assurance field instructions for the execution of the welding work and of the weld tests and inspections on the building site.

In particular, the technical code takes account of the stringent requirements which, in the case of these applications, must be set on the quality of the welded joint and thus on the proper execution of the welding work in a way suitable for the material. In particular, it provides remarks for the structural designing of welded joints between the various semi-finished products made of PE-HD.
