Introduction
Steel forms the essential part of Pakistan’s oil, gas, and pipeline infrastructure, helping to power industrial progress and supply energy. Pipeline construction, refinery building, and other facilities can’t do without its high strength, durability, and adaptability. This article talks about the role of steel in Pakistan’s energy sector, discusses the problems therein, and celebrates the remarkable achievements of Kamran Steel.
1. The Strategic Importance of Steel in Pakistan’s Energy Sector
Steel is widely used in Pakistan’s energy sector owing to its strength and flexibility. Pipelines made from steel carry oil and gas from mountainous territories to cities all over the country. Because of its ability to withstand pressure and high temperature, it is fit for these uses.
To give an example, the SSGC operates about 2,942 km of welded steel pipelines made of grades like API 5LX-42 to API 5LX-60, which are capable of managing up to 1,298 psig.
2. Major Pipeline Projects Utilizing Steel
a. White Oil Pipeline (WOP)
The pipeline linking Port Qasim and PARCO in Multan is a clear sign that steel is crucial for Pakistan’s energy needs. In 2000, the construction of this pipeline allowed for easier movement of imported oil throughout Mexico.
b. Iran-Pakistan (IP) Gas Pipeline
This pipeline, also known as the Peace Pipeline, is meant to bring natural gas from Iran to Pakistan. The project was delayed because of the international sanctions that were in place. In 2024, Pakistan greenlighted the construction of an 80 km long section of the pipeline within its country, stressing that steel is the best choice for such initiatives.
c. Gwadar–Kashgar Crude Oil Pipeline
This plan is meant to connect Gwadar in Pakistan to Kashgar in China for daily shipping up to a million barrels of oil. This project is significant as it supports regional growth by using steel to construct energy corridors.
3. Challenges in Steel Pipeline Infrastructure in Pakistan
Water, gas, and sewage in Pakistan are moved through the country with the help of steel pipelines. Although these reactors provide safer containment, high strength, and the ability to withstand pressure, they still face a variety of operational and environmental obstacles in developing countries such as Pakistan.
Major Challenges
1. Corrosion
Corrosion poses the greatest and longest-lasting threat to steel pipelines. In such areas, when sewage, water, and gas pipes are located together without sufficient protection, it is difficult to manage. As the soil contains moisture, salts, and chemicals, it rapidly leads to corrosion, pitting, rusting, and sometimes to leaks and bursts. This can lead to:
- Continual leaks and broken pipelines
- Polluted water is used for drinking.
- The risk of explosions is present in gas pipelines.
- High prices to maintain and replace.
2. High maintenance and Repair costs
It is necessary to watch over steel pipelines all the time, especially after several years, or if they are covered up. Performing inspection, cathodic protection testing, recoating, welding, and replacing segments requires a lot of resources and employees. The challenges that can occur are:
- Shortage of skilled workers in rural areas.
- Relying on old systems for monitoring.
- It costs a lot to buy spare parts and welding materials.
- Delays in handling emergencies arise because of poor infrastructure.
3. Influence of the Environment and Climate
There is a wide difference in weather in Pakistan, with hot and wet conditions on the coast and cold and freezing weather in the north. Such conditions may lead to:
- Cracks or fatigue in steel may result from temperature changes
- Earthquakes and other soil activity can cause movements that harm underground pipelines.
- Rainfall and humidity can cause metal to rust from both inside and outside.
4. Aging Infrastructure
The main pipelines in Pakistan were put in place back in the past decades. A lot of pipes have exceeded their expected lifespan and were not manufactured with modern materials or protection. Pressure is more likely to break down deteriorated joints and welds.
5. Lack of Proper Installation.
Due to budget shortfalls or mismanagement, some places use quick-fix installations that are not standard. This includes:
- The pipeline is poorly bedded or surrounded by backfill.
- Unsafe or improper ways of welding.
- The failure to add any protective coatings.
- People who are not specialists are completing essential jobs.
6. Third-party Damage
Often, urban development leads to the disturbance of underground pipelines. Due to digging by construction companies, municipal projects, or private developers, some items may be accidentally found.
- Line ruptures
- Gas leaks
- Interruptions in providing emergency services
Methods for Handling and Reducing the Issue
Different engineering, operational, and policy changes have been introduced by the industry and government to tackle these issues in Pakistan. This is a fuller explanation:
1. High-end Protective Coatings
Corrosion-resistant coatings are applied to modern pipelines before they are set up. Popular systems available are:
- 3-Layer Polyethylene (3LPE): A coat with an epoxy base, an adhesive layer, and a polyethylene outside layer that fights corrosion.
- Fusion-Bonded Epoxy (FBE) can withstand both high pressure and high temperatures.
- Bitumen and coal tar enamel coatings: Were widely used in the past but continue to be relevant now in some places.
2. Cathodic Protection
Steel pipes in this electrochemical system are protected from corrosion through the use of sacrificial anodes or impressed current. This rule applies to long-distance gas pipelines across Pakistan.
Types:
- For sacrificial anodes, CP is used in short pipelines or isolated systems.
- The newer version has improved its current capacity for long and important projects that require extra power.
3. Intelligent Monitoring Systems
With SCADA systems, companies can monitor their pipelines for integrity in real time. Features include:
- Leak sensors.
- Anomalies in pressure are detected.
- Managing valves over a distance.
- Analyzing information from the past.
4. Pipeline Inspection and Maintenance Equipment
Using the latest inspection procedures allows for early detection of weak areas. Common tools to use are:
- Pigs are smart tools that listen for corrosion, dents, and mistakes in welding activities.
- Ultrasonic Testing and Magnetic Flux Leakage make it possible to find hidden corrosion accurately.
- Above-ground pipelines are inspected using drones, and aerial areas are monitored from the air.
5. Adopting Alternative Materials
To prevent corrosion, more homes are using PE, PVC, and HDPE pipes for water and gas. These materials:
- Are non-corrosive
- Requires less money to set up.
- Can stretch, avoiding damage from soil shifting.
- It is efficient as it needs much less maintenance.
6. Building Zoning and Urban Planning Guidelines
The coordination of city planners, pipeline companies, and contractors should be improved to ensure:
- Place animals far enough away from the utility lines.
- Record the existence of underground networks properly.
- Get a sign and permit for the work to protect the property from outsiders.
7. Training and workforce development
Preparing the local workforce with technical certification through:
- Pipelines are welded and produced in various stages.
- Non-destructive testing (NDT) is used.
- The process of installing corrosion protection systems.
- Risk management guidelines and response to emergencies.
8. The government and its watchdogs.
WASO regulators, including OGRA (Oil and Gas Authority) and WASA (Water and Sanitation Agency), are in charge of implementation.
- Industry-specific engineering requirements (ASTM, API)
- Installation codes
- Inspection frequencies
- Required documents and auditing.
9. Saving emergency kits and building stockpiles.
Because of possible pipeline failures, urban centers are being equipped with replacement sleeves, emergency clamps, and mobile welding tools to minimize disruption.
10. Public Alert and Reporting Methods
Setting up hotlines and making mobile apps for people to use while reporting:
- Gas has a noticeable smell or release.
- The earth is soft around the lines due to water seepage.
- Excavation or digging activities aren’t permitted.
- With this, people can avoid hazards and help support the safe use of infrastructure.
