line pipe supplier

Line pipe is a type of steel pipe used primarily in the oil and gas industry for transporting oil and gas from the wellhead to storage facilities or refineries.


Line pipe is a type of steel pipe used primarily in the oil and gas industry for transporting oil and gas from the wellhead to storage facilities or refineries. Here’s a detailed description covering its specifications, applications, and advantages:


  1. Material: Typically made from carbon steel or alloy steel, though some variants may use stainless steel for specific applications.
  2. Diameter and Thickness: Comes in a variety of sizes, usually ranging from 2 inches to 48 inches in diameter. The wall thickness can vary depending on the pressure requirements.
  3. Coating and Lining: Often coated externally to protect against corrosion. Internal linings may be used to reduce friction or protect the pipe from the fluids being transported.
  4. Standards and Grades: Conforms to international standards like API (American Petroleum Institute) 5L, which specifies requirements for the manufacture of two product specification levels (PSL1 and PSL2) of seamless and welded steel pipes.
  5. Length: Typically available in lengths of 40 feet, but can be manufactured in longer lengths to meet specific project requirements.


  1. Oil and Gas Transportation: Primarily used for transporting crude oil and natural gas from extraction sites to refineries and storage facilities.
  2. Water Transport: In some cases, used for transporting water, particularly in oilfield water injection systems.
  3. Chemical Industries: Employed in the chemical industry for the safe transport of hazardous chemicals.
  4. Construction: Used in the construction industry, especially for structural purposes and in the foundation pilings.


  1. Durability: Highly durable and able to withstand high pressures and harsh environments, making it ideal for underground and underwater pipelines.
  2. Corrosion Resistance: With appropriate coatings, it offers excellent resistance to corrosion, which is essential in harsh chemical or saline environments.
  3. Flexibility in Size and Strength: Available in a wide range of sizes and strengths, making it suitable for various applications and pressure requirements.
  4. Cost-Effective: Provides a cost-effective solution for long-distance transportation of oil, gas, and other fluids.
  5. Safety and Reliability: Designed to meet stringent safety standards, ensuring reliable transport of fluids without leaks or ruptures.

This combination of specifications, applications, and advantages makes line pipe a critical component in the infrastructure of the energy, chemical, and construction industries.
