Numerous industrial applications require perfect welds in order to comply with standards, norms and regulations.
But in many cases this criteria is not achieved without a specific preparation of the tube before welding, especially if the cutting of the tube has not been done in a professional way, obtaining a perfect burr-free surface quality.
In this case, the squaring of the tube is mandatory.
Why is tube squaring important ?
In “high purity” industries such as pharmaceutical or food, no welding fault can be allowed. Errors in the installation can create favorable conditions for dirt and bacteria contaminations. This is also valid for micro-chemical applications, such as the semiconductor industry and many more. Generally, these installations are set up by an approved subcontractor, equipped with adapted cutting machines and orbital welding equipment, ensuring a perfect fault free result.
In case of maintenance, partial adjustments or for original equipment installation, the person responsible for the production site has to ensure that the preparation of the tubes and fittings is carried out correctly, maintaining the highest level of quality.

The replacement of orbital cutting machines by squaring machines is sometimes mandatory
Orbital cutting machines guarantee a perfect cut result but in some cases – according to the place where repair work must be done – the use of such equipment is not possible due to a lack of accessibility.
The use of metal cutting saws or other tools should be avoided as they create particles or chips that must not be admitted in any circumstances. Some techniques even modify the material characteristics of the metal due to the heat input…
There is one and only solution: the tubes have to be squared. In this case you can use a portable, lightweight machine, which can be used in any situation for thin walled tubes.
