Product Descriptions
1.Product description
WF-HQ550 Vapor Phase Corrosion Inhibitor is mainly composed of low-boiling heterocyclic amides with good dispersibility in both gas and liquid phases. It provides excellent anti-corrosion performance against comprehensive gas-liquid two-phase corrosion caused by H₂S and the liquid-phase H2S-H2O system formed by dissolved hydrogen sulfide in water. With effective chemical concentration maintained,the corrosion inhibition rate can reach ≥95%,and localized corrosion can be effectively controlled.This product is especially suitable for corrosion protection of water and high H 2S-containing natural gas gathering and transmission trunk lines,compressor stations,and oil and gas wells.
- Product Characteristics
- Good corrosion inhibition performance
- Excellent thermal and chemical stability
- Good dispersibility in both gas and liquid phases

Indexes Properties
Appearance Liquid
pH value (1%aqueous solution) 5-9
Solubility Soluble in alcohols,dispersible in water
4.Method of application
WF-HQ550 Vapor Phase Corrosion Inhibitor is generally diluted with low-carbon alcohols,then injected into pipeline systems via metering pumps or directly added to gas well casings.
The dosage shall be adjusted according to on-site H2S concentration and corrosion severity. Normally,200~500 ppm of this gas corrosion inhibitor is dosed based on the condensate water content in natural gas.
For newly commissioned gathering transmission and wastewater treatment systems, pre-filming treatment is required at a pre-filming concentration of 500 mg/L.
5.Packaging,storage and precautions
Packing:25kg,200kg ,1000kg or negotiated packing.
Store tightly sealed in a cool,dark place.Avoid long-term exposure to extremely high or low
temperatures.
The shelf life of the product is 1 year.
