Description

Submerged-arc welded tubes made of the heat-resistant non-alloy quality steel P235GH are used for steam pressure vessels, tube construction, pressure vessel and apparatus manufacturing mainly in the chemical industry for temperatures up to 200 °C and simultaneous high pressures. The total load and the special scale relationships may decrease or increase the temperature limit.
