About us

Long-lasting, secure connections – what the name AVIT-Hochdruck Rohrtechnik has meant for more than 60 years. As a family-owned enterprise, we are now the third generation producing high-quality steel and stainless steel pipeline components for machine and plant construction with high demands on safety. Under the company name ATI GmbH (automotive parts and industrial technology), company founder Ing. August Wasmuth developed a pioneering alternative to conventional cutting ring systems in 1954: the 24° weld nipple with O-ring gasket. The current internationally standard 24° conical seal screw connection has become synonymous with simple and secure pipe connection in heavy machine construction. Its technical advantages are still unbeatable!
