API 5L X42 and X52 line pipes are known for their strength, durability, and ability to transport oil, gas and other fluids in high–stress environments. The pipes are manufactured to the standard of the American Petroleum Institute (API) 5L specification and are synonymous with quality and conformity. Riyaarth Overseas manufactures high–quality API 5L X42/X52 line pipes for the Petroleum, Natural Gas and Petrochemical industries.
Key Features of API 5L X42/X52 Line Pipes
Seamless and Welded Construction:
- They are available in seamless and welded types, allowing for a variety of applications.
- Seamless pipes remove weak points for high-pressure applications.
High Strength and Durability:
- API 5L X42 has a minimum yield point of 42,000 psi (290 MPa) and X52 has a 52,000 psi (360 MPa) minimum yield strength.
- They have excellent tensile strengths of 60,000 psi (415 MPa) and 66,000 psi (455 MPa) respectively.
Corrosion Resistance:
- They are built for use in harsh environments and exposure to corrosive fluids and gases.
- They accept external coatings such as Fusion Bonded Epoxy (FBE) and 3LPE.
Versatile Compatibility:
- Appropriate for pipelines conveying oil, gas, water, and other fluids.
- Commonly utilized in industries including oil refineries, petrochemical facilities, electricity generation and offshore drilling.

Manufacturing Process
API 5L X42/X52 line pipes are manufactured using modern processes, so they provide superior quality:
- Steel Preparation: High-quality raw materials can be melted via basic oxygen or electric furnace processes.
- Hot Rolling: Billets or plates are heated and then shaped into pipes.
- Cold Drawing (if necessary): Achieves precise dimensional tolerances and improves mechanical properties.
- Heat Treatment: Boosts ductility and toughness.
- Testing & Inspection: Ensures compliance with API standards.
Common Applications
Oil and Gas Industry:
- Utilized in pipelines to transport crude oil and natural gas, along with refined products. They display excellent corrosion resistance, which ensures reliability over the long term.
- Can be used on offshore platforms; they provide high strength and corrosion resistance. They have durability for well into the deep sea or extreme environments.
Petrochemical Facilities:
- Used to transport chemicals that will be under extreme pressure and temperature. The resistance allows for efficient roofing while withstanding harsh chemicals.
- Provides durability and safety in aggressive industrial conditions. Reduces leakage risks and protects employees and equipment.
Power Plants:
- Appropriate for steam piping and cooling water systems in thermal power plants. Due to their thermal characteristics, they conduct heat effectively, resulting in minimal heat loss when transferring heat.
- Used in nuclear power plants for improved resistance to both heat and radiation. They also possess mechanical properties that provide mechanical support to high-pressure steam, with minimal risk of unstable conditions.
Construction & Infrastructure:
- Used in structural applications such as piling and support for heavy loads. Their mechanical properties also afford high loading capacities to maintain structural integrity in bridges and buildings.
- Provide durability and reliability for long-term periods after being exposed to harsh environmental conditions. Therefore, they can withstand severe weather, making them great options for both urban and coastal structures.

Testing and Quality Standards
To ensure they can be relied upon in critical applications, specific standards of testing must be adhered to:
- Hydrostatic Testing: Ensures their ability to withstand pressures.
- Non-Destructive Testing (NDT): The use of ultrasonic testing or radiographic testing.
- Chemical Analysis: Ensures the pipe complies with the known analysis of chemical composition.
- Mechanical Testing: Provides the tensile strength of the material, hardness, and resistance to impact.
Surface Finish and Coatings
To enhance durability:
- The standard finishes are black cured paint or varnish coatings, etc.
- Optional coatings include Fusion Bonded Epoxy (FBE), Three-Layer Polyethylene (3LPE) or Polypropylene (3LPP), etc.
Quality Assurance & Packaging
