Weâ??ve used four articles to list the characters for the API casing couplings. Today, we shall share the fifth one-non upset end (NUE). It would be good by using among steel pipeâ??s work no matter seamless steel pipe or stainless steel pipe. You can tell that it is may similar with external upset end (EUE) from the aspect of types, size and OD. In general, they have difference too. We would make a lesson before the purchase of these five API casing couplings and use them in the right place.
