|
Heat Exchanger Tubes Pipes |
Serving e.g. refineries(petroleum),chemical and pharmaceutical industries as well as fertilizer production and food industries |
|
Furnace Tubes Pipes |
Industrial furnaces and similar applications demand our heat-, high temperature- and corrosion resistant austenitic steel (usually with high carbon contents) and nickel-based alloys |
|
Nuclear Tubes Pipes |
(Power Gen, Waste treatment, Fuel fabrication) NSSS piping, Heat exchanger tubes (U-bent & straight), In-core instrumentation tubes, Instrumentation tubes for quality class 1, 2, 3 of the nuclear power application |
|
Oil and Gas Tubes Pipes |
OCTG (Oil Country Tubular Goods),Onshore and offshore oil and gas exploration and production need special tubular products to cope with high pressure and/or high temperature conditions as well as with highly aggressive substances |
|
Umbilical Tubes Pipes |
Subsea applications have to withstand aggressive sea water and must be essentially inert to the commonly used fluids transmitted through the tubes |
|
