The production of elbows takes place both with cold forming, in the Tecninox plant (Piacenza) and in Tecninox do Brasil (Brazil), and by hot forming in Petrol Raccord (Piacenza).
The wide range of materials we offer – from austenitic stainless steel, to super austenitics, to Titanium, to Nickel alloys, etc. – meets the demands of the most critical applications, from the chemical industry, to petrochemicals, offshore platforms, shipbuilding, energy production.
All our elbows are produced in accordance with quality and current technical standards (ASTM / ASME / ANSI) and are available in a wide range of thicknesses, grades and sizes (from ½” to 56″).
Our deep-rooted experience as manufacturers allows us to offer standard elbows, but also tailor-made ones, to customer’s drawing.
