About us
Schulte Gewindefittings GmbH, based in Kirchhundem-Würdinghausen (Siegerland), manufactures steel and stainless steel pipe connections, pressure vessel components and fittings such as sockets, pipe nipples, welding nipples, reducers, plugs, caps, nuts and hose tails in sizes from G 1/8" to 4" as well as sockets and nuts with metric threads M 6 to M 120. Production takes place on CNC lathes, with the company offering primarily custom versions and small series to drawing, among other things for pressure vessel construction with TÜV acceptance. Materials processed include seamless boiler tubes, thick-walled tubes, threaded tubes, welded steel tubes, precision steel tubes, bar and hexagonal steel as well as stainless steels such as 1.4301, 1.4541 and 1.4571. The product range also includes special turned parts (sleeves, bushes, adapters) with diameters from 12 to 160 mm and thread types such as G, R, NPT/NPTF per ANSI/ASME as well as UNC/UNF. Customers come from vessel construction, pressure vessel construction, apparatus engineering, shipbuilding, plant and mechanical engineering and pipeline construction, with a traditional focus on vessel manufacturers in the chemical industry in the Siegerland region. The company looks back on more than 50 years of family tradition since its founding in 1962.
