3pe anticorrosive steel pipe is used in different working environments. In order to slow down or prevent the pipeline from being corroded and deteriorated by the chemical or electrochemical action of the external medium or by the metabolic activity of microorganisms, the outer wall of the pipe is coated with 2 or 3 layers. Ethylene (3PE) in order to achieve pipeline anti-corrosion, 3pe anti-corrosion pipe life extension 3-5 times. The middle layer is usually a copolymer adhesive whose main component is polyolefin. Currently, vinyl copolymer adhesives are widely used. The functional groups of the polar part of the copolymer adhesive and the epoxy groups of the fusion epoxy powder coating can react to form hydrogen bonds or chemical bonds, so that the middle layer and the bottom layer can form a good bond; the non-polar vinyl part and the surface layer Polyethylene has a good affinity, so the middle layer and the surface layer also have good bonding properties. The main function of the polyethylene surface layer is to play a mechanical protection and anti-corrosion effect, which has the same effect as the traditional two-layer structure polyethylene anti-corrosion layer.

3PE anticorrosive pipeline structure

One layer of epoxy powder (FBE>100um), the second layer of adhesive (copolymer) 170～250um, and the third layer of polyethylene (PE) 25～37mm. These three materials are closely integrated and firmly combined with the steel pipe to form an excellent anti-corrosion layer. 2PE anticorrosive pipeline: the pipeline has two layers of PE anticorrosion structure, one layer of adhesive (AD), the second layer of polyethylene (PE), the two materials are integrated, and the thickness of each layer is the same as that of the three layers of PE. Three-layer PE anticorrosive structure of the pipeline: one layer of epoxy powder (FBE>100um), the second layer of adhesive (AD) 170～250um, and the third layer of polyethylene (PE) 25～37mm. The three materials are integrated and firmly combined with the steel pipe to form an excellent anti-corrosion layer. The pipe diameter ranges from Φ60 to Φ1420, and the wall thickness ranges from 25-18mm. This is a relatively good anti-corrosion method. Generally, it can increase the service life of 50 years, which not only prolongs the replacement cycle of underground pipeline equipment, but also greatly saves costs. State building has provided a powerful role! 3PE anti-corrosion is the most commonly used anti-corrosion method. In addition, there are 2PE, 2PP, 3PP. Their manufacturing processes are similar, but the raw materials are different. The characteristics of this kind of anti-corrosion are simple production process, good anti-corrosion effect, low price, and it is pipe manufacturing. Anti-corrosion method generally recognized by the industry.

Advantages of 3PE anticorrosive steel pipe

1. PE anticorrosive pipeline has extremely high sealing performance, long-term operation can greatly save energy, reduce costs and protect the environment.

2. Strong corrosion resistance, simple and quick construction, and the service life can reach 30-50 years.

3. It also has good corrosion resistance and impact resistance under low temperature conditions, and the PE water absorption rate is low (less than 0.01%).

4. At the same time, it has high epoxy strength, low water absorption of PE and good softness of hot melt adhesive. It has high anti-corrosion reliability. The disadvantage is that it is expensive compared with the cost of other splicing materials.

Oil country tubulars are an essential component in the oil and gas industry, used for drilling, production, and transportation of crude oil. However, these tubulars are prone to corrosion due to the harsh environmental conditions they encounter during their lifecycle. Corrosion not only reduces their lifespan but also poses a significant risk to safety and increases maintenance costs. To combat this issue, various measures have been introduced for oil country tubular anticorrosion. In this blog post, we will discuss some basic measures that can help prevent corrosion in these crucial components of the oil and gas industry. So buckle up as we delve into the world of 3pe anticorrosive steel pipe!

The problem of corrosion in oil country tubulars

Oil country tubulars are essential components of the oil and gas industry, used in drilling, well completion, and production operations. However, these tubulars are prone to corrosion due to their exposure to harsh environmental conditions such as high temperatures and corrosive fluids.

Corrosion can cause significant damage to oil country tubulars resulting in costly repairs or replacements. It can lead to leaks, loss of product containment, reduced structural integrity and ultimately endanger the safety of personnel and equipment.

Corrosion is often caused by chemical reactions between the metallic surface of the pipe and its surrounding environment. Factors that contribute to corrosion include pH levels, temperature changes, fluid velocity, oxygen concentration among others.

To prevent corrosion in oil country tubulars different anticorrosive measures have been put in place including coating with anti-corrosive materials such as 3pe anticorrosive steel pipe coatings which provide effective protection against rusting.

It is critical for operators in the oil and gas industry to take proactive measures towards preventing corrosion since it leads not only to financial losses but also poses a threat on human life.

Basic measures of oil country tubular anticorrosion

Oil country tubulars are an essential component in the oil and gas industry. However, they are highly susceptible to corrosion due to exposure to harsh environmental conditions such as high temperatures, humidity, and chemical reactions. Corrosion can lead to significant damage resulting in expensive repairs or replacement costs.

Basic measures of oil country tubular anticorrosion involve several techniques that aim at reducing the effects of corrosion. One common method is coating the surfaces with anti-corrosive materials like 3PE (three-layer polyethylene) which provides a protective layer against rust and other corrosive agents.

Another popular measure is cathodic protection which involves applying a low voltage electric current on the surface of the pipe material making it less reactive with its environment. This method not only reduces corrosion but also improves overall durability.

Regular maintenance practices such as cleaning, inspection, and repair should be conducted periodically to ensure optimal performance. These basic measures not only extend the life span of oil country tubulars but also reduce operational costs by minimizing downtime associated with repairs or replacements caused by corrosion-related damages.

Implementing these basic measures for oil country tubular anticorrosion ensures safe operations while maximizing profits for companies in this industry.

Conclusion

To sum it up, oil country tubular anticorrosion measures are essential in the oil and gas industry. The cost of corrosion can be detrimental to the entire operation, causing significant financial losses and safety hazards. Therefore, implementing basic measures such as 3PE anticorrosive steel pipes can prolong the lifespan of equipment while reducing maintenance costs.

It is always important to prioritize quality over convenience when choosing materials for your operations. By selecting high-quality anticorrosive materials, you are investing in a long-term solution that will benefit you in more ways than one.

We hope this article has been informative and helpful for those seeking information on basic measures for oil country tubular anticorrosion. Remember that prevention is key when it comes to corrosion control – by taking simple steps today; you can save yourself from headaches tomorrow!
