Our Gas Pipeline Services
A City Gas Distribution (CGD) pipeline is a network of pipelines designed to supply natural gas to residential, commercial, and industrial consumers within a city or region. It delivers piped natural gas (PNG) for homes and industries, as well as compressed natural gas (CNG) for vehicles. The CGD network ensures a safe, reliable, and efficient supply of natural gas, adhering to strict safety and regulatory standards to prevent leaks, maintain pressure control, and protect public health.
Trenching for gas pipelines demands meticulous planning to protect the environment and ensure the pipeline’s safety and durability. The process also requires strict adherence to regulatory standards and safety protocols.
Gas pipeline welding is a vital part of constructing natural gas transportation systems. It uses specialized welding techniques to join pipeline sections, ensuring strong, secure, and leak-free connections.
Gas pipeline testing is a crucial step to verify the integrity, safety, and reliability of a pipeline before it becomes operational. It includes hydrostatic testing, leak detection, non-destructive testing, and visual inspections to ensure complete safety.
Trenchless Pipeline Installation
We offer advanced trenchless pipeline solutions for the oil and gas industry. Our expertise ensures minimal surface disruption, faster project completion, and cost-effective installations even in challenging terrains. From crossing rivers and highways to navigating environmentally sensitive areas, we deliver reliable, sustainable solutions tailored to your specific needs.
What is Trenchless Technology?
Trenchless technology enables the installation, repair, or replacement of pipelines without extensive surface excavation. This innovative method reduces environmental impact and is especially suited for urban, offshore, and environmentally sensitive areas.

Trenchless Technology Process
Trenchless Technology is a modern method of installing, repairing, or replacing underground pipelines and utilities without the need for large-scale surface excavation. Instead of digging long trenches, advanced techniques like horizontal directional drilling (HDD), microtunneling, and pipe jacking are used
Horizontal Directional Drilling (HDD)
- Proven method for pipeline installation under rivers, roads, and urban areas
- Supports various pipeline diameters and materials
- Minimal surface disruption
- Precise installation over long distances
- Reduced environmental footprint
Microtunneling
- A trenchless technique that uses a remotely controlled tunneling machine to install pipelines.
- Perfect for small-diameter pipelines in areas with limited access
- Offers high precision, unaffected by surface conditions
- Minimizes soil disruption and waste, protecting surrounding ecosystems
- Though initial setup costs can be higher, it often proves more cost-effective over time, especially in urban settings
Pipe Jacking and Auger Boring
- A method of installing pipelines by pushing them through pre-drilled tunnels.
- Minimizes surface disruption, ideal under roads and rivers
- Best suited for short-distance projects in stable soils
- Ensures precise pipeline alignment
- Cost-effective and faster, especially for small to medium pipelines in urban areas with limited access
Direct Pipe Installation
- Combines microtunneling and horizontal directional drilling (HDD) for single-pass pipeline installation.
- Ideal for crossing water bodies and highways with minimal surface disruption
- Provides precise control over alignment and depth for efficient pipeline placement
- Suitable for diverse soil conditions and challenging environments, including urban areas

Pipeline Testing & Commissioning Solutions
Hydrostatic Testing
The pipeline is filled with water and pressurized to check for leaks and structural strength. Pressure levels are then monitored over a set period to confirm the pipeline’s integrity and reliability.
Pneumatic Testing
For pipelines operating in extreme environments, we provide safe and precise air or inert gas pressure testing. Our team follows strict safety protocols to minimize risks and ensure reliable results throughout the process.
Drying and Dewatering
Residual water and moisture are eliminated using advanced techniques such as vacuum drying or super-heated air, ensuring the pipeline is clean, dry, and ready for operation.
Purging and Inerting Testing
Oxygen is replaced with inert gases such as nitrogen to eliminate combustion risks, ensuring the pipeline is safely prepared for operation.
Valve and Component Testing
All valves, pressure relief systems, and fittings are thoroughly tested to confirm functionality and ensure seamless integration with the pipeline’s operational system.
Final Commissioning Test
We integrate and calibrate SCADA systems to enable real-time monitoring and control. Flow, pressure, and temperature are thoroughly tested to ensure smooth and efficient pipeline operation.
