Valves for oil refineries

Refineries are among the most demanding valve buyers. Flammable media, high temperatures, hydrogen sulphide and strict quality control shape every line item.

Main valve types

Steel wedge gate valves to API 600 or GOST, globe valves, check valves and fire-safe ball valves. High-temperature units use alloy steels.

Sour service

Feedstocks and products containing hydrogen sulphide cause sulphide stress cracking. Materials are selected to NACE MR0175 / ISO 15156 with hardness control.

Emissions and fire safety

Stem packing must limit fugitive emissions, and flammable service requires fire-safe performance proven by testing.

Quality and documents

Material certificates, test records, frequent third-party inspection and a manufacturer’s data book. TAZ supplies general-purpose steel valves for utilities and discusses special designs project by project.
