Boagaz tubes




Stainless steel corrugated pipes

BOAGAZ gas pipes are available as rolls in sizes ranging from DN15 up to DN50 and are authorised for use in Europe for indoor gas installations for pressures up to 500 mbar. The particular characteristic of our pipes is that they are triple heat-treated and hence free from residual stress and inherently stable. This also renders them flexible. The pliability of the pipes means that the bending required during installation can be performed easily by hand. This can be done in a matter of seconds dispensing with the need for elbow joints, thus enhancing the safety of the entire gas installation.

With BOAGAZ you can undertake connectionless installations over long stretches. In the best case scenario only two connection points are required – one at the beginning and another one at the end of the installation. In any case, by using BOAGAZ you can keep connection points to a minimum, thus saving time and money.

Materials & Technology

We only use high-quality stainless steel of grade 1.4404 for our pipes, which are heat-treated. This heat treatment gives the pipe its special characteristics in terms of dimensional stability and freedom from residual stress. Each pipe is then checked for leaks using helium and a PE lining of yellow corrosion protection is applied. Our pipes are placed in cardboard boxes or wound onto wooden reels and distributed as rolled products. The pipes are checked within the system for compliance with EN 15266 and are accompanied by numerous country-specific certifications and tests.
