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: How do you inspect steel pipes for defects?
Inspecting steel pipes for defects involves a systematic approach that combines visual inspection, non-destructive testing (NDT) techniques, and specialized equipment. Here are the steps typically followed to inspect steel pipes for defects: 1. Visual Inspection: Start by visually examining the external surface of the pipe, looking for any visible signs of defects such as cracks, dents, or corrosion. Pay close attention to welds, joints, and areas susceptible to stress or damage. 2. Ultrasonic Testing (UT): Ultrasonic testing is commonly used to detect internal defects in steel pipes. It involves using ultrasonic waves that are sent into the pipe and then interpreted based on the echoes received. Any irregularities in the internal structure, like cracks or voids, can be identified and analyzed. 3. Magnetic Particle Inspection (MPI): MPI is a widely used technique to detect surface and near-surface defects such as cracks, seams, or other discontinuities. This method involves applying a magnetic field to the pipe and then applying ferromagnetic particles (usually iron-based) on the surface. These particles will accumulate and form visible indications at the areas of magnetic flux leakage caused by defects. 4. Eddy Current Testing (ECT): Eddy current testing is suitable for detecting surface and near-surface defects in conductive materials like steel. It involves inducing an alternating current into the pipe and monitoring the changes in the electrical currents induced by any defects present. These changes are then analyzed to identify and evaluate the defects. 5. Radiographic Testing (RT): Radiographic testing is performed by exposing the steel pipe to X-rays or gamma rays and capturing the resulting radiographic images. This technique allows for the detection of internal defects such as cracks, porosity, inclusions, or wall thickness variations. The radiographic images are then examined for any indications of defects. 6. Dye Penetrant Inspection (DPI): DPI is a method used to detect surface-breaking defects in steel pipes. It involves applying a liquid dye on the surface, which penetrates into any surface cracks or flaws. After allowing the dye to seep in and adequately react, excess dye is removed, and a developer is applied to draw out the dye from the defects, making them visible. 7. Pressure Testing: Pressure testing involves pressurizing the steel pipe to a predetermined level and monitoring for any pressure drops or leaks. This test ensures that the pipe can withstand the required pressure without any structural defects. It is important to note that the inspection technique used depends on various factors, such as the type of defect being sought, the size and nature of the pipe, and the specific industry standards and regulations. Inspection professionals with expertise in NDT methods and equipment are typically employed to ensure accurate and reliable results.
Q: What are the safety considerations when working with steel pipes?
When working with steel pipes, safety considerations include wearing appropriate personal protective equipment such as gloves, safety glasses, and steel-toed boots to prevent injuries.

Q: How are steel pipes used in the construction of geothermal power plants?
Steel pipes are used in the construction of geothermal power plants for various purposes. They are primarily used to transport and circulate the geothermal fluid, which carries the heat from the underground reservoir to the surface. These pipes are typically made of high-quality steel that can withstand the high temperatures and corrosive nature of the geothermal fluid. Additionally, steel pipes are used in the construction of injection wells, where cool water or other fluids are injected back into the reservoir to maintain pressure and sustain the heat extraction process. Overall, steel pipes play a crucial role in the efficient and reliable operation of geothermal power plants.
Q: What is the difference between the stainless steel pipe welded pipe and seamless pipe?
Grain size: usually, the grain size of the metal is related to the heat treatment temperature and the time at which the metal is kept at the same temperature. Therefore, the welded pipe and seamless tube annealing of the same grain size. If the minimum tube cold treatment, the grain size of the weld metal is smaller than the grain size, welding or grain size is the same.Strength: the strength of the pipeline in the composition of the alloy and alloy containing the same and the same heat treatment of seamless tube and seamed tube essentially consistent strength. After the tensile test and three-dimensional vibration test, tube tearing almost all occurred in the welding point or away from the heated area where. This is because there is little impurity in the weld and the nitrogen content is slightly higher, so the strength of the welded joint is better than that of other parts. However, the ASME Boiler and Pressure Vessel Association believes that the seamed tube can withstand 85% of the allowable pressure, which is mainly due to improved welding equipment data collection prior to today. The provisions of ASME 100% completely under license by ultrasonic testing pressure tube. Similarly, Europe and Asia also stipulates that can ensure the quality of welding performance by eddy current test tube, the eddy current testing is subject to legal procedures and licensed institutions. Trent's eddy current test was approved by the Swedish power division. ASME believes the current loss is relatively small, high-quality performance based on the seamed tube.
