About Soyka
Soyka GmbH Rohrverbindungen from Bochum has been a partner for pipe connections and pressure equipment components for over 60 years. The company manufactures flanges to DIN, EN 1092-1, ASME, MSS, BS, API, JIS and GOST as well as special flanges, spectacle blind and spacer plates, fittings such as reducers, tees, long welding necks, caps and nozzles, plus strainers (bucket, T and Y type) from DN50 to DN1000 with CE marking, as well as pressure-bearing plant components such as valve bodies and protective and startup screens. The basis is a raw material stock of approximately 2,000 tonnes consisting of blanks, round bar, rings and plate from certified EU suppliers; around 60 material grades from Alloy and Duplex through titanium to aluminium alloys are permanently in stock. CNC-controlled machining includes turning up to 2,700 mm workpiece diameter, milling and drilling; targeted heat treatment in the company's own furnace quickly sets the required mechanical-technological properties. Together with Mohr Engineering GmbH, Soyka also offers design, calculation, engineering and CE marking of pressure equipment.
