Steel reducers

Butt welding reducers are produced by pressing. The semi-finished product is rolled seamless tubes. Reducers are mainly used as part of pipelines in the construction, energy engineering and mining industry. Dimensions of tube reducers are: outside diameter of 26.9 -114, 3 mm, wall thickness from 2.3 to 3.6 mm, NPS 3/4 - 4

Steel for butt welding reducers

Reducers are made from carbon and low alloy steels, which are presented in table.

Dimensions and dimensional tolerances of welding reducers

Dimensions of delivered reducers are shown in dimensional table; dimensional tolerances are in accordance with relevant standards.

Heat treatment, condition of delivery and surface

The input tubes used for production of reducers are heat treated. Reductions are delivered with the inner and outer surface descaled not preserved, without surface protection or with surface treated by blasting.

Ends customization of the reducers

Upon agreement it is possible to supply reducers with a wall thickness of more than 3 mm with adjustment for a weld according to DIN 2559 standard

Testing of weld reducers

The input tubes and ready made reducers are tested according to requirements and the appropriate standards.

Marking of the weld reducers

Reducers are marked as required by standards or agreement. Marking is done usually by stamping the agreed data.

Packaging of weld reducers

Reducers are packaged in cardboard boxes or metal pallets.

Certificates for weld reducers

Certificates are issued according to either DIN 50 049 or EN 10 204 standards.
