FAQs

What Are the Internally Lined and Externally Coated Pipes?

Internally lined and externally coated pipes are steel pipes that have been treated with protective coatings both inside and outside. The internal lining, often an epoxy or other polymer, prevents corrosion and reduces friction within the pipe. The external coating, such as 3LPE (three-layer polyethylene), provides an additional barrier against external environmental factors and physical damage.

What Are the Benefits of Using Special Lined and Coated Pipes?

  • Enhanced Corrosion Resistance: Protection against internal and external corrosion significantly extends the pipe’s lifespan.
  • Improved Flow Efficiency: Internal linings reduce friction, enhancing the flow of fluids and gases.
  • Lower Maintenance Costs: Reduced risk of corrosion and damage decreases the need for frequent maintenance and repairs.
  • Versatility: Suitable for various environments, including harsh and corrosive conditions.

What Are the Applications of Internally Lined and Externally Coated Line Pipes?

  • Oil and Gas Industry: Used for transporting crude oil, natural gas, and other petroleum products.
  • Water and Wastewater Treatment: Applied in pipelines for potable water and sewage systems.
  • Chemical Processing: Used in transporting corrosive chemicals and other hazardous materials.
  • Marine Applications: Suitable for offshore and subsea pipelines exposed to seawater.
  • Industrial Infrastructure: Used in various industrial applications requiring robust and reliable piping solutions.

How Many Types of Both Internally Lined and Externally Coated Pipes?

There are several types of internal linings and external coatings:

  • Internal Linings:
    • Epoxy
    • Cement mortar
    • Polyurethane
    • Fusion-bonded epoxy (FBE)
  • External Coatings:
    • 3LPE (Three-layer polyethylene)
    • 3LPP (Three-layer polypropylene)
    • Fusion-bonded epoxy (FBE)
    • Coal tar enamel

Is the Ext. 3LPE Coated & Int. Antistatic Epoxy Primer Lined Pipe Suitable for Jet A-1 Fuel Pipeline?

Yes, the external 3LPE coated and internal antistatic epoxy primer lined pipe is suitable for Jet A-1 fuel pipelines. The 3LPE coating offers robust external protection against physical damage and corrosion, while the antistatic epoxy lining prevents static charge buildup and provides internal corrosion resistance, ensuring safe and efficient fuel transportation.

Is the Ext. 3LPE Coated & Int. Friction-Reducing Epoxy Primer Lined Pipe Suitable for Noncorrosive Gas Transmission?

Yes. The external 3LPE coated and internal friction-reducing epoxy primer lined pipe is suitable for noncorrosive gas transmission. The 3LPE coating protects the pipe from external environmental factors. At the same time, the friction-reducing epoxy lining enhances flow efficiency and reduces pressure loss, making it an excellent choice for gas transmission pipelines.
