2- and 3-way valves for melt pipe diameters up to 90 mm (others on request)
Melt pipes with electrical-, oil- or vapour heating
Including insulation and instrumentation (melt pressure, melt temperature)
Incl. static mixers if required
Melt pipe length without flanges up to 4 m, flanges also oil- or vapour heated
Design according to pressure vessel codes if required (AD2000, ASME)
