Weldtron

THE UNIVERSAL PRODUCT FOR THE TRANSPORT OF LIQUIDS.

Weldtron is the dockweiler universal product for the transport of liquids. The pipes and fittings are available in metallic or electropolished versions. They comply with the hygiene classes H3 to HE3 according to DIN 11866/11865/11864.

For optimum weldability, Weldtron attaches particular importance to the composition of the enamel. This is proven by welding tests and guaranteed.

After the inner surfaces have been cleaned, the pipes and fittings are capped and welded in sturdy foil.
