Quality testing

TW couplings at LMC are regularly tested. As the TW locking ring is mostly affected by falling, extra testing is done to ensure our customers a high quality product.

The test levels are:

  •  mechanical resistance
  •  material composition
  •  manufacturing process
  •  dimensions
  •  design
