Butt welding elbows are produced by extrusion pressing. The semi-finished product is rolled seamlesssteel tubes. Butt-welds are mainly used as part of the construction of pipelines, energy engineering and mining industry.
Steel for butt welding elbows The elbows are made of steel, which is located above in the survey table and is divided according to purpose of use. The elbows meet the requirements of NACE MR 0175.
Heat treatment, delivery condition The elbows produced by hot forming are available without heat treatment, annealing is included in the normalized forming. Upon agreement the outer surface can be machined by blasting.
Dimensions of butt welding elbows Dimensions are given in tables according to EN standards and in accordance with ASME standards.
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.
