Line Pipe for Gas & Oil Service

Overview

In the rapidly evolving energy sector, our line pipes stand out as a pivotal element in the transportation of gas and oil. Designed to meet the stringent API SPEC 5L standards, our pipes are manufactured with a focus on quality and reliability, serving the oil and natural gas industries effectively. With state-of-the-art processing methods, including cold drawing, hot rolling, and hot expanding, our pipes meet diverse project needs.

Specifications

Our line pipes come in a variety of specifications tailored for optimal performance in harsh environments:

• Outer Diameter (O.D.): Ranging from 1/2" to 28" (21.3mm to 711mm)
• Wall Thickness (W.T.): From 0.078" to 2.362" (2mm to 60mm)
• Length Options: Maximum length of 13,000mm, with fixed lengths of 5.8M, 6M, 11.8M, and double random lengths (DRL)

These specifications ensure that our line pipes can accommodate various project demands, whether for new installations or replacements.

Applications

Our line pipes are primarily used for:

• Transporting gas, water, and petroleum across extensive pipeline networks
• Serving critical functions in both the oil and natural gas industries

These applications highlight the essential role our pipes play in ensuring energy supply, safety, and operational efficiency.

Chemical Composition and Mechanical Properties

We offer a range of steel grades, each with specific chemical compositions to enhance performance in unique environments. This ensures optimal durability and strength under pressure. Below are the key grades:

1. Grade A or L210

   • C: ≤0.22%
   • Mn: ≤0.90%
   • P: ≤0.030%
   • S: ≤0.030%
   • Ti: ≤0.25%

2. Grade B or L245

   • C: ≤0.28%
   • Mn: ≤1.20%
   • P: ≤0.030%
   • S: ≤0.030%
   • Ti: ≤0.25%

3. X42, X46, X52, X56, X60 Grades

   • Varying manganese content enhancing range from ≤1.30% to ≤1.40%, suitable for higher strength applications.

4. Special Grades (e.g., X42R, X42N)

   • Enhanced compositions with lower sulfur and phosphorus levels, ideal for specific environmental requirements.

Each grade is designed for optimal toughness, with additional properties to withstand corrosive environments, high temperatures, and pressures.

Manufacturing Process

Our manufacturing processes are tailored to maintain the integrity of the pipes at every stage:

• Cold Drawing: Increases strength and hardness while maintaining precise dimensions.
• Hot Rolling: Ensures a fine microstructure and superior mechanical properties.
• Hot Expanding: Provides increased size without compromising material quality.

These advanced techniques result in line pipes that are not only reliable but also environmentally sustainable, adhering to modern energy requirements.

Quality Assurance

Quality assurance is critical in our manufacturing process. Rigorous testing is conducted at various stages to ensure compliance with international standards. This includes:

• Hydrostatic testing to verify pressure capacity
• Non-destructive testing (NDT) to detect any internal or surface defects
• Mechanical testing to guarantee the desired strength and ductility

By adhering to strict monitoring and testing protocols, we ensure that our products consistently meet the rigorous demands of the oil and gas industries.
