Chemar Pipelines Ltd. is one of the largest plants in Poland producing industrial and technological pipeline components according to individually developed and agreed technical execution conditions with the customer and in compliance with the standard PN-EN 13480, PN-EN 12952 and supervisory regulations WUDT/UC/2003. We have authorizations in the field of manufacturing techniques and a certificate of the Integrated Quality, Environmental and Occupational Health and Safety Management System in accordance with standards PN-EN ISO 9001:2015, PN-EN ISO 14001:2015, PN-EN-45001:2024 guarantee that our customers' requirements are met.
Pipeline fittings manufactured in Chemar Rurociągi Sp. z o.o. are combined into elements ready for assembly on the construction site, the so-called spools.
Curved arches
Bends are made from carbon steel, low-alloy steel, alloy steel, duplex steel, and superduplex steel, seamless or longitudinally welded. Bends are produced on an induction-heated bending machine or on mechanical bending machines.
Bent arches made on an induction-heated bending machine with smooth bending radius adjustment:
Outer diameter of the pipe: Dz= 60.3 mm ÷ 1020 mm
Bending angle: α = 0.5° ÷ 185°
Bending radius: R = 250 mm ÷ max 6000 mm (but R ≥ 2D)
Wall thickness: g = max 100 mm
Bent arches made on mechanical bending machines:
Outer diameter of the pipe: Dz= 10.2 mm ÷ 168 mm
Bending angle: α = 0.5° ÷ 180°
Bending radius: R = 2 D up to 600 mm
Wall thickness: 2.5 mm to 20 mm
Bent arches are made according to the standard PN-EN 13480, PN-EN 12952.
Segmental arches
Segmental bends are made from welded and seamless steel, carbon, low-alloy, alloy, duplex and superduplex steel pipes.
Scope of application:
Diameter range:
seamless steel pipes: 108 mm ÷ 508 mm
with longitudinal seam: 508 mm ÷ 2020 mm
