Plasma purified products for oxygen applications

Oxygen applications

Certain safety and accident prevention regulations must be observed when handling oxygen (O2). Oxygen as a medium itself is not flammable, but in combination with a flammable substance, e.g. oil or grease, it can self-ignite due to frictional heat, electrostatic discharge or spark over.

Oil and grease-free

Under the aspect of quality assurance, SUCO pays attention to the provision of oil and grease-free individual parts and their further processing when selecting its suppliers. However, it cannot be ruled out that isolated minute quantities of lubricating oil may adhere to a workpiece.

Since even the slightest oil or grease residue is sufficient to cause a fire or explosion when handling oxygen, SUCO recommends that only plasma-cleaned components be used when handling oxygen or other flammable air-gas mixtures.

Plasma cleaned products

The cleaning process through the plasma cleaning system ensures that no more than 20 mg of organic hydrocarbon compounds are detectable per m². The maximum purity level of 20 mg/m² corresponds to level B based on ASTM G93-3:2004.

As a sealing material, SUCO recommends the use of EPDM seals for oxygen applications, the burnout resistance of which has been certified by the German Federal Office for Materials Testing (BAM).

LABS-free

The acronym LABS refers to "paint wetting impairment substances" such as lubricants, oils, greases or silicones. During the painting process, LABS can cause contamination and coating defects on the paint film.

With a longer process time and the use of LABS-free gloves and PE bags, SUCO's new plasma cleaning system can also achieve LABS compliance according to the VDMA 24364 standard sheet.
