Redrawn tubes

Consistent with traditionally perfectionist Swiss manufacturing tradition, ZM takes the greatest of care during the manufacture of their high precision redrawn and stainless steel tubes in order to guarantee exceptional characteristics:

Incredibly strict dimensional tolerances

Ultra smooth state of surfaces

Specific mechanical values

Manufacture of very short of pieces

With this product, a very wide range is possible (diameter range between 5 and 70 mm). “Customer is king” - Whatever your requirements are, we will suggest a perfectly adapted tube, which bares in mind all of your production constraints.

Our tubes can be delivered in lengths varying from ‘very long’ to very small, even just a few millimetres.

As with the welded tube range, a large pallet of tests are possible.

Stainless Steel

Through serious investment over the years, ZM Tubes has established itself as specialist in stainless steel tubes. We are capable meeting the highest and most varied of requirements. Here are some types of stainless steel used:

Austenitic
304/304L/316/316L/316SL/316TI/321/317L/317LN

Super Austenitic
904L/254SMO/N08926/N08800/AL6XN®

Duplex
S32101/S32304/S32205/S31803/S32750/S32760
Ferritic
S44100/S44400/S43035 High Nickel Alloy
600/601/625/602/825

Refractory
310S/321H/304H

Nickel is a determining metal in the composition of stainless steels. Depending on its content levels, the cost of tube materials is strongly influenced. You can consult nickel rates on the Link.

Welded tubes

The characteristics of these products are highly appreciated by boilermakers and prime chemical contractors, by petro-chemists, energy and food processing companies.

Our production methods confer strong resistance to corrosion, excellent resistance, a longer life span, as well as perfect seal. These characteristics are assured by a large variety of tests.

Tubes welded by ZM Tubes in Switzerland are carefully examined in connection with thermal variations, as can be found in heat exchangers, condensers, evaporators, steam generators, boilers, heaters, dryers, etc.

The range of welded tube dimensions are the following:

diameter: 15.88 - 63.5 mm

thickness: 0.5 - 3 mm

length: up to over 30 m
