Tubing<\/strong><\/strong><\/a> is the conduit used<\/strong><\/a> to transport crude<\/strong><\/a> oil<\/strong><\/a> or natural<\/strong><\/a> gas<\/strong><\/a> from the producing formations to the field<\/strong><\/a> surface<\/strong><\/a> facilities for process<\/strong><\/a>ing<\/strong><\/a> after drill<\/strong><\/a>ing<\/strong><\/a> is completed. During<\/strong><\/a> the extraction<\/strong><\/a> process, the octg<\/strong><\/a> tubing<\/strong><\/a> must with<\/strong><\/a>stand<\/strong><\/a> the pressure<\/strong><\/a> and it must be adequate<\/strong><\/a>ly strong to resist loads and deformations associated<\/strong><\/a> with production<\/strong><\/a> and workovers. In addition, tubing generally is size<\/strong><\/a>d to satisfy the expected rates<\/strong><\/a> of production of Oil and Gas<\/strong><\/a>. That is because<\/strong><\/a> if tubing is too large<\/strong><\/a>, we will have an economic<\/strong><\/a> impact<\/strong><\/a> beyond<\/strong><\/a> the cost<\/strong><\/a> of tubing oil and gas itself, how<\/strong><\/a>ever, if \u00a0API<\/strong><\/strong><\/a> tubing is too small, it will restrict the production of oil or gas, and if things<\/strong><\/a> continue this way it will impact subsequent economic per<\/strong><\/a>formance<\/strong><\/a> of the well<\/strong><\/a>. Generally, tubing is manufacture<\/strong><\/a>d in the same way as casing<\/strong><\/a>, except an additional process known as \u201cupsetting\u201d whic<\/strong><\/a>h is applied to thicken the Pipe<\/strong><\/strong><\/a>s.<\/p>\n

Outside diameter<\/strong><\/a> of tubing is from 1.660\u201d to 4 1\/2\u201d (42.16mm to 114.3mm); wall<\/strong><\/a> thickness<\/strong><\/a> is from 2.3 PPF to 26.10 PPF (3.57mm to 9.52mm). based<\/strong><\/a> on the standard<\/strong><\/a> of api 5c<\/strong><\/a>t<\/strong><\/a>, iso<\/strong><\/a>11960, GOST, and their<\/strong><\/a> steel<\/strong><\/a> grade<\/strong><\/a> are from h40<\/strong><\/a>, J55<\/strong><\/strong><\/a>, N80<\/strong><\/strong><\/a>, n80q<\/strong><\/a>, L80<\/strong><\/strong><\/a>, l80-1<\/strong><\/a>, L80-9Cr, L80-13Cr, P110<\/strong><\/strong><\/a> etc. As you know the Length<\/strong><\/a> range<\/strong><\/a> is R1 (6.10-7.32M), R2 (8.53-9.75M), R3 (11.58-12.8M), R2 is used frequently. Besides EU and NU end type<\/strong><\/a> could be provided by Anson, IJ and premium<\/strong><\/a>s Thread<\/strong><\/a> type are also available.<\/p>\n
