Detailed Product Description
Secondary Or Not: Non-secondary Application: Oil Pipe
Technique: SMLS Special Pipe: API Pipe
Alloy Or Not: Is Alloy

The external upset end (EUE) API tubing uses taper pipe with round thread. It realizes connection and seal through the joint upsetting. After the thickening of both ends, heat treatment, thread processing, and installing of the coupling and thread protector are carried out in order.

The EUE API tubing has two main features. Without changing the thread shape, the joint size increases through the upsetting process. This leads to a substantial increase in the connection strength and meets the requirement of downhole operation. In addition, it achieves sealing effect through the thread compound. There is a 0.076mm gap between addendum and crest. When tightening threads, the crest clearance is filled with thread compound. After the compound after is solidified, it will block the leak channel, so as to achieve the sealing effect.

NOTE Nominal linear masses are shown for information only.
a Labels are for information and assistance in ordering.
b The densities of martensitic chromium steels (L80 9Cr and 13Cr) are different from carbon steels. The masses shown are therefore not accurate for chromium steels. A mass correction factor of 0.989 may be used.
c The minimum outside diameter of upset D4 is limited by the minimum length of full-crest threads. See API Spec 5B.
d For pup joints only, the length tolerance on Leu is between(-1,+4). The length on Lb may be 4 in longer than specified.
e For extended length upsets on external upset tubing, add 1 in to the dimensions in columns 6, 7 and 8.
