Valves play a key role in the oil and gas industry, and their applications cover the whole industry chain from oil and gas extraction, transportation to processing. Due to the complex working conditions of the oil and gas industry (high pressure, high temperature, corrosive media, etc.), valves must have high reliability, resistance to extreme environments, leak-proof design and long life.

 

Applications of valves in the oil industry

 

I. Upstream Exploration and Production

a. Wellhead Control

- Applications: switch control, pressure regulation, blowout prevention (BOP system) of oil and gas wells.

 

b. Subsea Production System

- Applications: pipeline control and emergency cutoff of deep-sea oil and gas fields.

 

II. Midstream Transportation and Storage

a. Long-distance Pipeline

- Applications: trunk transportation of crude oil and natural gas, and pressure control of distribution stations.

 

b. Storage Tanks & Terminals

- Applications: import and export control of storage tanks, safe pressure relief.

 

III. Downstream Processing and Refining

a. Refinery

- Applications: medium control of high-temperature and high-pressure reactors and fractionation towers.

 

b. Petrochemical Plant

- Applications: ethylene cracking, hydroprocessing, and catalyst transportation.

 

IV. Special working conditions

a. High sulfur oil and gas fields (Sour Gas)

 

b.Shale gas/coalbed methane extraction

- Applications: fracturing fluid (hydraulic fracturing) injection control, return fluid treatment.

 

c.Liquefied natural gas (LNG)

- Applications: LNG liquefaction, storage, gasification.
