What is EUE tubing?
Upset Tubing (EUE) is a long tubing with joint installed in a wellbore to facilitate the extraction of oil and gas.
What is an EUE connection?
The API external-upset-end (EUE) tubing connection is widely used because it is a good, serviceable connection in most wells. The EUE joint has a designed joint strength in tension and pressure strength greater than that of the pipe body and, therefore, is considered a 100% joint efficient connection.
What is EUE 8RD?
Extended performance means enhanced economics. The TKC Convertible EUE connection system extends the per- formance life of your API 8RD threaded tubing through its innovative, high-performance ring and pin design.
What is the ID of 2 7 8 tubing?
Speedy Metals 2-7/8″ OD x 2.375″ ID x . 250″ Wall Other Steel Round Tube.
What is J55?
API J55 is a general purpose pipe manufactured to API specification 5CT. Similar to K55 except the minimum tensile strength is lower. API K55 is a general purpose pipe manufactured to API specification 5CT. Usually, this grade is most often used in casing applications.
What is L80 tubing?
This is a controlled yield strength material with a hardness testing requirement. L80 is usually used in wells with sour (hydrogen sulfide) environments. Available in casing dimensions of 114.3 mm (4.5″) to 406.4 mm (16″) Available in tubing dimensions of 26.7 mm (1.05″) to 114.3 mm (4.5″) OCTG and Linepipe.
What is J55 tubing?
J55 Tubing is placed within the casing. It is used to transport oil and gas from the source rock to the wellhead.
How do you calculate tubing stretch?
Total Elongation is simply calculated by adding the components of elongation. Thus the total elongation is given by: S TOTAL = S tubing weight + S chemical weight + S pump force + S thermal S TOTAL = 16.2 ft + 2.2 ft + 0.2 ft + 16.8 ft .
What is the weight of 2 7 8 tubing?

What is a BTC connection?
BTC type. It is designed to improve axial tensile or axial compressive load capacity and to provide leakage resistance performance. It is an excellent connection for use in well situations involving higher axial loads and moderate internal pressures and temperatures.
What are the 3 common tubing sizes used?
The most used sizes are: 2-⅜”, 2-⅞”, 3-½” and 4-½”. The tubing joint length: is the length of tubing joint including the coupling and excluding the pin thread.
What is J55 material?
General Purpose Steel Grades offered by U. S. Steel: API J55 is a general purpose pipe manufactured to API specification 5CT. Similar to K55 except the minimum tensile strength is lower. API K55 is a general purpose pipe manufactured to API specification 5CT.
What is EUE tubing used for?
The API external-upset-end (EUE) tubing connection is widely used because it is a good, serviceable connection in most wells. The EUE joint has a designed joint strength in tension and pressure strength greater than that of the pipe body and, therefore, is considered a 100% joint efficient connection.

How can I improve the seal performance of EUE tubing?
For proper lubrication and sealing, the joint requires thread compound as defined in API RP 5A3 . To improve the seal performance of API EUE tubing in high-pressure service, a grooved coupling, which accepts nonmetallic seal rings, is sometimes used in the coupling (see API Spec. 5CT SR 13 ).
What is the diameter of EUE tubing coupling?
API EUE Tubing Couplings. Designed in accordance with API 5CT/5B and are made of good seamless steel. EUE petroleum tubing coupling cover the outer diameter from 77.80mm to 141.30mm, that is bigger than the outer diameter of the non upset threaded end product. We carry size range of 2-3/8”, 2-7/8″, 3-1/2″,4″ and 4-1/2″ in J55, K55, N80,…
