API-5CT EUE Tubing Pipe

The API external-upset-end (EUE) tubing pipe is broadly used due to the fact that is a good, serviceable interconnection in the majority of wells.

Without the need of modifying the actual thread shape, the joint dimension will increase because of upsetting procedure. The EUE joint features a designed joint strength in tension and pressure strength much higher than that of the pipe overall body and, as a result, is considered a 100% joint effective connection.

To enhance seal efficiency of API EUE tubing in high-pressure system, a grooved coupling, which accepts nonmetallic seal rings, is quite often applied in the coupling (see API Spec. 5CT SR 13).

API EUE joints come in OD sizes of 1.050 to 4.500 inch.

Inspection

Physical properties are checked and each length hydrostatically tested, normally to only 3,000 psi in the plain end (unthreaded) condition. The following are also checked:

Dimensions
Weights
Straightness
Lengths

Part of this inspection is to drift all lengths.
Despite all the American Petroleum Institute (API) specifications and testing, some tubing defects are still found after delivery; thus, some operators do further inspection.

Q: Can steel pipes be used for conveyor systems?: Yes, steel pipes can be used for conveyor systems. Steel pipes are known for their strength, durability, and resistance to wear and tear, making them suitable for handling heavy loads and continuous operation in conveyor systems. Additionally, steel pipes can be easily welded, allowing for customization and flexibility in conveyor designs.

Q: How do steel pipes compare to other types of piping materials?: Steel pipes are widely considered to be one of the most durable and strong types of piping materials available. They offer superior strength, resistance to corrosion, and can withstand high pressure and extreme temperatures. Compared to other materials such as PVC or copper, steel pipes have a longer lifespan and are more suitable for heavy-duty applications. Additionally, steel pipes are highly recyclable, making them an environmentally friendly choice.

Q: How are steel pipes tested for leaks?: Steel pipes are typically tested for leaks using various methods such as hydrostatic testing, pneumatic testing, or advanced technologies like ultrasonic testing. In hydrostatic testing, the pipe is filled with water or another liquid, and pressure is applied to check for any leaks. Pneumatic testing involves using compressed air or gas to pressurize the pipe and identify potential leaks. Ultrasonic testing employs high-frequency sound waves to detect any leaks or flaws in the steel pipes. These testing methods ensure the integrity and quality of steel pipes before they are put into use.

Q: What are the common standards for coating and lining of steel pipes?: The common standards for coating and lining of steel pipes are outlined by various organizations and regulatory bodies to ensure the durability, corrosion resistance, and overall quality of the pipes. Some of the widely recognized and used standards include: 1. American Society for Testing and Materials (ASTM): ASTM has developed numerous standards for coating and lining of steel pipes, such as ASTM A775/A775M for epoxy-coated reinforcing steel, ASTM A1064/A1064M for metallic-coated steel wire, and ASTM A1057/A1057M for fusion-bonded epoxy-coated steel reinforcement. 2. American Water Works Association (AWWA): AWWA has established several standards for coating and lining of steel pipes used in the water industry. Examples include AWWA C210 for liquid epoxy coating systems for the interior and exterior of steel water pipelines, and AWWA C213 for fusion-bonded epoxy coating for the interior and exterior of steel water pipelines. 3. National Association of Corrosion Engineers (NACE): NACE International develops standards and recommended practices for the corrosion control of steel pipes. NACE SP0169 provides guidelines for selection and application of coatings for underground or submerged steel pipelines, while NACE SP0198 offers recommendations for external coatings of steel pipelines. 4. ISO Standards: The International Organization for Standardization (ISO) has developed various standards related to coating and lining of steel pipes. ISO 21809-1 specifies the requirements for external coatings applied to buried or submerged pipelines, while ISO 21809-2 focuses on the internal coating and lining of such pipelines. These standards cover different aspects of the coating and lining process, including surface preparation, application methods, minimum coating thickness, adhesion, and quality control. Adhering to these standards ensures that steel pipes are properly protected against corrosion, abrasion, and other forms of deterioration, leading to longer service life and enhanced performance in various industries such as oil and gas, water supply, and infrastructure.

Q: What are steel pipes?: Steel pipes are cylindrical tubes made of steel that are used for conveying fluids or gases, as well as for structural purposes in various industries.

Q: What are the different standards and specifications for steel pipes?: There are several different standards and specifications for steel pipes, depending on their intended use and application. Some of the commonly used standards include ASTM A53, ASTM A106, ASTM A333, and API 5L. These standards define various aspects such as the chemical composition, mechanical properties, dimensions, and testing requirements for steel pipes. Additionally, specific industries may have their own specifications, such as ASME B36.10 for seamless and welded steel pipes used in piping systems.

Q: How are steel pipes used in geothermal energy systems?: Steel pipes are commonly used in geothermal energy systems to facilitate the transport of fluids, such as water or steam, between the geothermal source and the power plant. These pipes are designed to withstand high temperatures and pressures, ensuring the safe and efficient transfer of geothermal fluids. Additionally, steel pipes are used in the construction of geothermal wells, providing structural support and maintaining the integrity of the wellbore.

Q: Can steel pipes be used for underground gas storage?: Yes, steel pipes can be used for underground gas storage. Steel pipes are commonly used in underground gas storage facilities due to their strength, durability, and resistance to corrosion. They provide a reliable and secure means of storing and transporting gas underground.

Q: Can steel pipes be used for offshore oil and gas platforms?: Offshore oil and gas platforms can utilize steel pipes, as they are known for their durability, strength, and ability to withstand harsh marine conditions. These pipes are typically constructed from high-quality steel alloys, capable of enduring the immense pressures and temperatures of offshore drilling and production activities. Moreover, steel pipes offer versatility and easy welding, facilitating the creation of intricate pipeline networks on offshore platforms. Furthermore, protective coatings like epoxy or anti-corrosion coatings can be applied to steel pipes, bolstering their resistance to corrosion and extending their lifespan in the offshore environment. In summary, steel pipes are a reliable and extensively employed option for transporting oil and gas on offshore platforms.

Q: How are steel pipes repaired if they develop leaks?: Steel pipes can be repaired if they develop leaks through various methods such as welding, clamping, or using epoxy compounds. The specific repair technique depends on the size and location of the leak as well as the type of pipe, and it is typically carried out by trained professionals with the necessary equipment and expertise.
