SPT Tanks

Tanks for small power transformers, built in flat wall construction from structural steel plate, cut, formed, welded, coated and tested in-house.

  • Tank weights below 7 tons
  • Flat wall construction
  • S235 · S355 · stainless where specified
  • Leakage & pressure tested

MPT Tanks

Tanks for medium power transformers. As tank size grows, stiffening, lifting and transport requirements grow with it; stiffener layout and wall build-up follow the customer's specification.

  • Tank weights from 7 to 20 tons
  • Customer-spec stiffening
  • S355 · S355NL grades
  • Dimensional control before welding

LPT Tanks

Tanks for large power transformers, the heaviest fabrications in the range. Welding sequence and fit-up are planned to control distortion, so covers and flanges seat correctly on assembly.

  • Tank weights up to 35 tons
  • Distortion-controlled welding
  • Leakage & pressure tested before dispatch
  • Stainless where specified
