>>Tubing Couplings are short lengths of pipe used to connect 2 joints of tubing.
>>All the tubing couplings are manufactured to meet API Specification 5CT.
>>Tubing couplings are available with NUE Thread,EUE Thread.
>>API NUE tubing coupling is used much less than EUE tubing.
>>The cost of NUE is only slightly less than EUE, and the joint strength is substantially less.
>>The coupling joint diameter of NUE is less than EUE, which offers some advantages when clearance is small.
>>The Tubing Couplings are manufactured to meet the requirements of API 5CT certifications respectively.
>>The casing couplings are applied in casing whose sizes are from 1.05 to 4-1/2inch.
