COATED PIPE
Les coated pipe, also called Insulated Pipe, is a group of metal pipes with anti-corrosion coatings. These pipe coatings are commonly utilized to preserve the steel pipe used in the building of pipelines, reinforcing steel, and a broad variety of piping connections.
Oil and gas coating pipe can be classified into two types, each with its own set of unique and stringent requirements: revêtement interne des tuyaux et les tuyaux à revêtement extérieur.
With TUSPIPE’s own coating technology and production lines, you can customise your pipe coating to meet your production requirements. Whether it’s internal coating pipe or external coating pipe, we always put quality first!

INTERNAL COATED PIPES
Revêtement interne des tuyaux
The internal pipe coating increases their resistance to corrosion, enhances their flow, and reduces the creation of deposits. There are a variety of interior coatings for pipes, including Fusion Bonded Epoxy (FBE) Coating and Glass flake Coatings.
Pipe coatings are very common and are generally categorized into two types: internal and external coatings. According to the type of coating, it can be divided into: coal tar enamel, cement slurry sand, epoxy resin, polyurethane, FEB/LPE/LPP and so on.
Below is a description of the types of coatings that TUSPIPE Steel Pipe Factory can offer you to help the health of your piping system.
External coated Pipe types
External pipelines coating are an important part of the oil and gas industry. They provide a barrier between the metal of the pipe and the environment, protecting the pipe from corrosion and other damage. Coatings also help to resist bacteria and chemicals that can be harmful to the pipeline. In addition, they can help to regulate temperature and protect the pipe from mechanical damage. The type of coating that is used depends on the specific needs of the pipeline. However, all coatings play an important role in protecting the pipeline from damage and ensuring its safe operation.
External Coated Pipes types
The Fusion Bonded Epoxy (FBE) coating prevents corrosion on pipe surfaces. Double or triple layers of FBE may even improve friction and abrasion resistance. In 3-layer PE/PP coating systems, FBE coating is also employed as the priming layer.
At temperatures ranging from 220 to 235°C, the electrostatic epoxy powder is sprayed onto a pipe. When the epoxy powder reaches the hot pipe surface, it melts and forms a uniform layer of epoxy coating on the pipe.
Dual-layer FBE is used for a variety of service applications, including directional drilling, anti-abrasion for road and river crossings, and oil, gas, and waterworks pipes. This coating, like single layer FBE (above), can be applied on a wide range of outer diameter (OD) sizes, from 3.5″ to 48″. In most situations, the top layer of abrasion resistance protects against erosion.
2LPE Coating is a two-layer polyethylene coating system that provides excellent protection for steel pipelines from corrosion, chemical attack, and abrasion. The first layer is a high-density polyethylene (HDPE) liner that is applied to the steel surface. The second layer is a co-polymer adhesive that bonds the HDPE liner to the steel surface. This two-layer system provides outstanding resistance to a wide range of chemicals and temperatures. 2LPE Coating is an ideal solution for protecting steel pipelines in a wide range of environments.
2LPP Coating is a steel pipeline coating that consists of a two-layer system. The first layer is a fusion-bonded epoxy (FBE) which provides corrosion and chemical resistance. The second layer is a polyethylene copolymer that provides mechanical protection and resistance to abrasion and cathodic disbondment. This type of coating is often used in high temperature environments, as it can withstand temperatures up to 120 degrees Celsius. 2LPP Coating is an effective way to protect steel pipelines from corrosion, chemical attack, and abrasion.
The three-layer polyethylene coating system offers superior protection against corrosion compared to traditional epoxy powder and two-layer PE coatings. The FBE layer provides an effective barrier against corrosion, while the PE layer resists water penetration and mechanical damage. This coating system can withstand temperatures of up to 50°C (low and medium density polyethylene) or 70°C (high-density polyethylene), making it an ideal choice for a wide range of applications.
3PP coating is a three-layer polypropylène anticorrosive coating that is primarily used as an anticorrosive pipeline layer for conveying high-temperature mediums and as an anticorrosive pipeline layer in desert areas with high surface temperatures and long periods of sunshine. The 3PP coating consists of a base layer of epoxy powder, an intermediate layer of binder, and an outer layer of polypropylene (PP) jacket. The 3PP coating takes all of the benefits of the 3PE coating and improves its operating temperature performance significantly. The improved operating temperature performance of the 3PP coating makes it an excellent choice for use in high-temperature environments and desert conditions.
