Materials

The equipment we manufacture is very often operated under difficult conditions – high temperatures and high pressure, or in contact with corrosive media. The use of appropriate materials for manufacturing pressure equipment is one of the key conditions for their flawless operation and high performance.

We pick the materials which work best with the operating medium, guarantee safety and demonstrate resistance to external conditions, while meeting our client’s device service life requirements. In the design process we take into account both normal and transitory operating conditions, which might occur during manufacturing, testing, transport and operation. At the client’s request we can perform tests of the material in contact with the medium.

Purchasing large amounts of non-standard materials requires an insight into the global market, while their processing and welding cannot be properly done without experience, appropriate authorisations and technologies.

The materials we process work with the following media: oxygen, hydrogen, nitrogen, carbon dioxide, benzene, oil, steam, water, nitric acid, ammonia, phosphoric acid, sulphuric acid, hydrochloric acid, hydrofluoric acid, monochloroacetic acid, isobutane, propane, butane, chlorine complexes, sulphur, potassium hydroxide (caustic potash), cyclohexanone, natural gas, diesel oil, kerosene, paraffin, nitrous gases, resin, hydrogen sulphide gas, amines and many other temporary process operating media.
