Box Loading Test System

The box loading test system from SCITEQ  can perform two methods of testing pipes and fittings or joints for their resistance to deformation and leakage, when subjected to sustained external loading in conjunction with the passage of hot/cold water according to ISO 13 260.

Product highlights:

  • high accuracy temperature control
  • user-friendly operation
  • suitable for  pipe sizes  Ø110-510mm
  • easy-to-use touch panel PLC
  • easy access to box loader container


A pipe/fitting sample is placed on a gravel bed and covered with gravel. A constant vertical load is applied via the gravel and temperature cycling is performed. Vertical deflection of the test piece is measured. A further feature is the optional conveyor system that eases gravel handling in terms of filling and emptying the box. The system uses tanks containing hot and cold water supplies depending on test method.  

The box loading system comprises three main parts; the box loader itself with compression plate, adjustable sides and pipe/fitting inlet/outlet, the tank system and the control cabinet combined with a chiller (chiller only needed for method A). Additional optional parts are the gravel conveyor system and the gravel storage container.

SCITEQ’s system may be configured to perform method A, B or both. The BLT is suitable for pipe sizes Ø110-510mm.

A highly durable solution

The box loader itself is heavy-duty and constructed in a way to allow a high degree of flexibility in terms of size adjustability depending on the actual pipe dimension and composition (straight pipe or assembly) to be  tested. The gravel will cause severe wear of the inner box and thus the inner box has been constructed in wood which is easily replaceable.

The box is accessible in more ways for instance to allow tamping of the gravel, to position the test piece, to load and unload gravel etc.


The tank system in stainless steel consists of two water tanks (depending of test method). Return water is lead back to the correct water tank thus saving energy. Continuously circulation in the tanks ensures consistent temperature.

Control cabinet

The control cabinet contains high quality components carefully chosen for their compatibility worldwide. The state-of-the art touch panel is very service friendly and offers excellent functionality.

Touch panel

The box loader is operated from a user-friendly control touch panel PC offering:

  • Accessible for remote support
  • Instant overview of test progress and alarms
  • Convenient control in manual operation
  • Easy extraction of excel test report via USB
