Corrosion-inhibitor injection
Continuous controlled-volume dosing into pipelines and process systems, with materials and pressure rating selected for the complete duty.
Petrox EngineeringHigh-pressure controlled-volume injection
API 675 Chemical Injection Pumps for Oil & Gas
Petrox Engineering supports specified chemical-injection duties with VK Pumps selection, datasheet review, package coordination, inspection documentation and commissioning assistance.
Applications
Where Petrox supports oil and gas
Scale-inhibitor dosing
Low-flow injection packages configured for stable output, suitable turndown and the required process connection pressure.
Demulsifier and process-additive injection
Metering systems for approved production chemicals, designed around chemical compatibility, viscosity and control requirements.
High-pressure injection
Plunger or hydraulic-diaphragm technologies evaluated against containment, maximum differential pressure, fluid properties and project specifications.
Multi-head and multiplex arrangements
Common-drive or coordinated pump arrangements for multiple injection points, capacity expansion or project-specific redundancy.
Packaged chemical injection skids
Tanks, pumps, valves, pulsation control, instruments and local controls supplied within clearly defined battery limits.

Frequently asked questions
Technical questions from project teams
Does every oil-and-gas chemical injection pump need API 675?
The purchaser and project specification determine the applicable standard. Where API 675 is required, the complete offered pump, package, testing, documentation and deviations must be reviewed.
Can Petrox coordinate inspection documentation?
Yes. The agreed scope can include datasheets, drawings, quality plans, inspection notifications, test records and final documentation.
