Fabrication of HP piping for Urea plants

Bending and welding of pipe classes according to Uhde HPT Standards PN-200, PN-325 und PN-500
All piping must be corrosion-resistant and should also satisfy the particularly stringent requirements dictated by the location in the urea plant and by the process licenser.
Uhde supplies completely prefabricated and tested isometrics and spools. The high demands on the scope of tests carried out and on the fabrication process can only be satisfied by a comprehensive quality system and properly qualified personnel. This means, for example, that each weld has to be X-rayed several times and that corrosion resistance has to be tested according to the instructions prevailing for each combination of welding filler metal, piping and fitting material.
Controlling aggressive fluids
The standard method of testing stainless steel used for urea plants is the Huey test, however, depending on the materials, the Streicher test or Strauss test can also be applied.
Isometrics
Verification of the geometry (by laser measurement)
Pressure test
Leakage test
