Process & Pipeline Services

At Pipeontec, we understand that the backbone of any industrial facility is the integrity of its pipelines and process systems. Whether you’re commissioning a new installation, performing routine maintenance, or preparing for shutdown, your infrastructure needs to operate at peak performance without compromise.

Our Process & Pipeline Services are built to meet the highest safety, reliability, and compliance standards. From hydro testing and leak detection to flushing, purging, and commissioning, we provide end-to-end support that gets your systems running safely and efficiently while minimizing downtime.

Our Services at a Glance

Hydrostatic Pressure Testing

Hydro testing is a non-negotiable part of ensuring your pipes and pressure vessels are leak-free and structurally sound. We use advanced pressurization equipment to fill the system with water and pressurize it to 1.25 to 1.5 times the design pressure or to your exact project specifications.

Every test is conducted with precision, closely monitored using calibrated gauges and digital pressure recorders. Our goal is not just to tick off a checklist but to give you long-term assurance in your system’s strength and safety.

Dewatering & Dry Air Flushing

Post hydro-testing or before commissioning, pipelines must be free of residual moisture to prevent corrosion and contamination. Our dewatering services efficiently remove trapped water or liquids using mechanical or pneumatic methods, followed by dry air flushing to achieve the required dryness levels.

We monitor dew point levels to ensure the pipeline is thoroughly dry ready for product flow, inert gas pressurization, or further testing.

Nitrogen Purging & Preservation

Oxygen and moisture are two of the biggest enemies of metal pipelines. Our nitrogen purging services displace air, oxygen, and other flammable or corrosive gases from the system, creating a stable and inert environment. This is especially critical before introducing hydrocarbons into new systems or when preserving idle lines.

We tailor nitrogen pressure levels based on the system layout and purpose, ensuring safety, preventing corrosion, and complying with your operational protocols.

Controlled Bolting & Flange Management

Loose bolts and misaligned flanges are common culprits behind leaks and failures in pipeline systems. That’s why we offer controlled bolting services using calibrated hydraulic, pneumatic, and electric torque tools. Our expert technicians follow proven torque and tensioning sequences, guaranteeing joint integrity.

With a systematic flange management program, we track, inspect, and document every flange joint ensuring each one meets the torque specifications and alignment requirements.

Nitrogen Helium Leak Detection

When precision matters, we turn to Nitrogen-Helium Leak Testing. Using a 99% nitrogen and 1% helium gas mixture, we detect even microscopic leaks in your system. Helium, with its tiny molecular size and inert properties, can pinpoint leak paths that other gases can’t reach.

A mass spectrometer detects helium presence in real-time, offering unmatched sensitivity and accuracy especially in hydrocarbon systems where safety and compliance are critical. For non-hydrocarbon lines, we also perform pure nitrogen leak tests to verify pressure integrity.

Pipeline Commissioning

Before any system goes live, it must be tested, cleaned, and inspected thoroughly. Our pipeline commissioning services include leak tests, nitrogen purging, drying, and final quality verification ensuring that every joint, valve, and segment is fit for service.

We approach commissioning as the final validation step making sure your pipeline doesn’t just work, but operates at full performance from day one.

Lube Oil Flushing

Clean lubrication systems are essential to prevent damage to high-speed machinery like turbines and compressors. We offer lube oil flushing services, using high-velocity flow to dislodge particles, debris, and varnish from stainless and carbon steel piping systems. We also provide chemical cleaning for carbon steel systems where heavier contamination may be present.

Every flushing job includes cleanliness monitoring typically using ISO 4406 particle counts to verify that your system meets OEM and industry standards.

Pneumatic Pressure Testing

Where hydro testing isn’t suitable due to weight, fluid incompatibility, or system design we offer pneumatic pressure testing. Pressurizing the system with air or inert gas to 1.1 times the design pressure, we identify leaks and verify system integrity with minimum disruption and no water intrusion.

This service is ideal for systems that need to be kept dry or where water-based tests are impractical.
