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 determine the required support spacing for steel pipes?
- The required support spacing for steel pipes is determined by considering various factors such as the pipe diameter, material strength, operating conditions, and local building codes and regulations. One of the primary considerations is the pipe's diameter. Larger diameter pipes generally require more frequent support than smaller diameter pipes to prevent excessive deflection and sagging. The material strength of the pipe is also important, as stronger pipes can span longer distances without additional support. The operating conditions of the pipe, such as the fluid being transported and the temperature, can also impact the required support spacing. For example, pipes carrying heavy or corrosive fluids may need more frequent support to prevent excessive stress and potential failure. Local building codes and regulations often provide specific guidelines for the minimum support spacing for steel pipes. These codes may take into account factors such as the pipe diameter, material strength, and operating conditions, as well as safety considerations and structural requirements. In general, it is essential to consult relevant codes, standards, and engineering guidelines to determine the required support spacing for steel pipes accurately. Additionally, working with qualified engineers and professionals experienced in pipe design and installation can ensure that the support spacing meets all necessary requirements and ensures the safe and efficient operation of the piping system.
- Q:Can steel pipes be used in the oil and gas industry?

They provide durability, strength, and resistance to heat and corrosion, making them ideal for withstanding the harsh conditions of vehicles.
- Q:What are the common standards for coating and lining of steel pipes?
- The most common standards for coating and lining of steel pipes include the American Petroleum Institute (API) standards such as API 5L, API 5CT, and API 5LD. Other widely recognized standards include the American Water Works Association (AWWA) standards such as AWWA C210 and AWWA C213, as well as the National Association of Corrosion Engineers (NACE) standards such as NACE RP0188 and NACE RP0394. These standards ensure the proper selection, application, and performance of coatings and linings to protect steel pipes from corrosion and other external factors.
- Q:Can steel pipes be used for drinking water supply?
- Yes, steel pipes can be used for drinking water supply. Steel pipes are commonly used in water distribution systems due to their strength, durability, and ability to withstand high pressures. However, it is important to note that the steel used in these pipes must be specifically designed and approved for potable water applications to ensure that it does not contaminate the water with any harmful substances. Additionally, proper maintenance and regular inspections are necessary to prevent the formation of rust or corrosion, which can affect the quality of the water.
