Methods and importance of degreasing and cleaning of oxygen valves and pipelines

Oxygen valves play a critical role in industrial processes, and their cleanliness is paramount for safety and efficiency. During manufacturing, transportation, storage, and installation, oxygen valves can accumulate contaminants such as welding slag, rust, grease, and dirt. These impurities pose significant safety risks and can lead to various operational challenges. For example, sparks caused by impurities might ignite explosions, and contamination can damage instruments, clog pipelines, or degrade product quality and production efficiency. Therefore, it is essential to degrease and clean oxygen valves and oxygen pipelines before use to ensure they meet the required cleanliness standards.

Oxygen Valves and Pipelines

Why Degrease Oxygen Valves?

Contaminants like oil residues, rust, and mechanical debris on oxygen valves can result in:

Fire Hazards: The presence of grease or oil in an oxygen-enriched environment increases the risk of combustion or explosions.

Equipment Damage: Impurities can clog instruments and measuring devices, reducing their precision or causing permanent damage.

Operational Disruptions: Blockages in the pipeline can impede flow and disrupt processes.

Quality and Efficiency Loss: Impurities can negatively affect the quality and quantity of the output.

Proper degreasing ensures safe and efficient operation by creating an optimal environment for production processes.

Methods of Degreasing Oxygen Valves

1.Degreasing Materials

Different materials can be used for degreasing oxygen valves:

Organic Solvents:

Examples include dichloroethane, trichloroethylene, and carbon tetrachloride. While effective, these solvents are rarely used due to their environmental and health risks. However, they may still be employed for wiping small valve parts.

Industrial Alcohol: Typically used for preliminary degreasing.

Acetone: Effective but highly flammable and volatile, making it hazardous and restricted for general use.

Water-Based Degreasing Agents:

Acidic or alkaline water-based degreasers are widely used due to their environmental friendliness, ease of waste treatment, and suitability for recirculating cleaning processes.

Other Agents:

Steam: Used where steam is readily available.

Quartz or Steel Sand: Employed for rust removal and initial degreasing but requires oil-free compressed air.

2.Degreasing Methods

Wiping Degreasing:

Suitable for small valve components, where contaminants are removed using solvents or cleaning agents with cloths.

Soaking Degreasing:

Ideal for parts or equipment that cannot undergo circulating cleaning. Soaking is often used for preliminary degreasing before assembly.

Circulating Degreasing:

The most effective method, combining degreasing with processes like pickling or passivation. This technique employs organic solvents or water-based agents to achieve superior cleaning results.

Other Requirements

In addition to degreasing, oxygen pipelines must meet the following conditions:

Oil-Free Surface: The surface must comply with oil content limits.

Rust-Free and Particle-Free: Ensure the pipeline is free from rust and mechanical particles.

Dryness: Pipelines should be dry and free of moisture. For systems with specific dew point requirements, they must be dried to the required level.

Passivation: If required by the client, both carbon steel and stainless steel pipelines must undergo passivation to enhance corrosion resistance.

The degreasing and cleaning of oxygen valves and pipelines are critical steps in ensuring safety and operational efficiency. By selecting appropriate degreasing materials and methods, and meeting cleanliness requirements, industries can minimize safety hazards, enhance equipment performance, and optimize production processes. These practices create a clean and secure environment for high-efficiency operations.
