TDT and WDT Inspections for Tanker Trucks
PHS Magnum prepares tanker trucks for TDT and WDT testing. We service tankers for liquid, chemical and hazardous (ADR) materials.
TDT vs. WDT — What Is the Difference?
In Poland, tankers fall under different supervisory bodies depending on the medium transported:
| Authority | Scope | Inspection frequency |
|---|---|---|
| TDT (Transport Technical Inspection) | Pressure vessels on vehicles — silos, cement tankers, dry bulk pressure tanks | External inspection every 2 years, pressure test every 6 years |
| WDT (Military Technical Inspection) | Liquid tankers, ADR tankers, LPG | Intervals set individually by the authority |
For combination vehicles (e.g. silo trailers with ADR authorisation), both bodies may have jurisdiction. PHS Magnum coordinates the documentation for such cases.
Preparation Scope
- Tank leak test — pneumatic and hydraulic pressure test to applicable standards
- Repair and replacement of armature: drain valves, bottom outlets, safety valves, pressure relief valves
- Tank welding (TIG/MIG) — certified welders, documented to EN ISO 15614
- Inspection and repair of the breathing system (vent valves, dip tubes, breathing valves)
- Internal coating inspection and renewal — relevant for food-grade and chemical tankers
- Documentation: repair protocols, material certificates, welding certificates, coating records
- ADR marking update — orange hazard boards, UN class symbols
Tanker Types Serviced
PHS Magnum prepares the following tanker categories:
- Fuel tankers — ADR class 3, steel with coating or aluminium
