2-3/8'' EUE 8RD - 3.063'' x 1.995'' An oilfield barrel equals 42 US gallons. Inspection Class: Fluid Capacity: Notes: -Tube / Pipe body properties are calculated based on uniform OD and wall thickness. 2,200. Remaining Body Wall: Tensile Strength: 1.0. FF. ft-lbs. Premium Class 80%.

2023年6月3日 · Tubing is manufactured to API 5CT 87-1/2% RBW and inspected to minimum Premium Class (80% RBW). Maximum make-up torque is that value above which there is no additional benefit, or reason to exceed. It is not meant to indicate the maximum torque the connection can withstand.

2020年4月28日 · The most common type of casing connection in use is the API 8-rd connection, where 8-rd means 8-round or eight threads per inch and a slightly rounded profile. The profile is a V or wedge-shape but slightly rounded at the crest and valleys of the threads. There is also an API 11.-V thread, which has 11. threads per inch and a sharp V profile.

Recommended Torque Table for UEU Tubing. API EUE = External Upset End tubing connections. 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.

2015年6月4日 · EUE = External Upset Ends, forging of ends on (API) tubing and drill pipe to provide additional thickness for strengthening connections. The EUE refers to a casing or tubing connection in which the inside diameter remains constant, but the outside diameter is enlarged to accommodate the threaded connection.

• API 5B EUE or OD 8rd or 10rd threaded connections • Multiple sizes to match all of the manufactured pipe sizes and pressure classes • Mill tested to 1.25 times Design Pressure Rating
