High pres­sure fluids

About the product

The pres­sure-trans­mit­ting medi­um will usu­ally be a suit­able liquid, but in some cases it will also be a gas. Most oils solid­i­fy at ambi­ent tem­per­at­ures above around 2,500 bar and are then unus­able as a pres­sure-trans­mit­ting medi­um. The solid­i­fic­a­tion point can, how­ever, be shif­ted to high­er pres­sure val­ues ​​by redu­cing the vis­cos­ity, for example by adding pet­ro­leum. Water from 20 ° C to 25 ° C is still sol­id under 9,000 bar to 10,000 bar. At 10 ° C even at 7,500 bar. A high pres­sure liquid mix­ture of glycol, water and a rust inhib­it­or is often used. There are also a num­ber of syn­thet­ic flu­ids on the mar­ket which, as a rule, have to be mixed with pet­ro­leum or a sim­il­ar medi­um for pres­sures above 7,000 bar. Inert gases can be highly com­pressed without restric­tions. When using oxy­gen, due to the high risk of explo­sion when com­ing into con­tact with oils, the highest pre­cau­tion­ary meas­ures must be taken. The same applies to the use of air and oxy­gen. When design­ing a gas sys­tem, it is import­ant to know that the com­press­ib­il­ity of the gas decreases sharply with increas­ing pres­sure. Liquid-like dens­it­ies are achieved at room tem­per­at­ure even at pres­sures from 1,000 bar.

We offer you a range of high pres­sure media for your application.
