NET4GAS operates pipelines for the international transit and national transmission of natural gas with a total length of more than 3,800 km, with nominal diameters ranging from DN 80 to DN 1400 and nominal pressures ranging from 4.0 to 8.4 MPa.
The required gas pressure in the pipelines is provided by compressor stations located at Kralice nad Oslavou, Kouřim, Břeclav and Veselí nad Lužicí. The total installed power of the compressor stations is 243 MW.
Natural gas is accepted and delivered upon the entry into and exit from the Czech Republic, i.e. its volume and quality are measured at border transfer stations – between the Czech Republic and Slovakia at Lanžhot, between the Czech Republic and Germany at Hora Svaté Kateřiny, Olbernhau, Brandov and Waidhaus. Between the Czech Republic and Poland, gas is measured at Cieszyn on the Polish side.
