The tubing size and grade chart below provides comprehensive dimensional and material specifications for API-certified production tubing, including outside diameter (OD), wall thickness, nominal weight, and connection types such as external upset end (EUE) and non-upset.

Pressure-proof polyester braiding, firmly embedded between two layers of silicone, lends this tubing its particular durability an re-sistance to pressure. The tubing is individually packaged in p lues listed are typical. Tubing is a relatively small-diameter pipe that is run into a well to serve as a conduit for the passage of oil and gas to the field surface facilities for processing. Further, tubing must be. Braid reinforced tubing is an extrusion which fully encompasses a metal or fiber braided profile between two layers of polymer. We offer braided tubing as-is or with advanced secondary operations, such as "overlap" or "butt end" welding of softer materials at the distal end, along with smoothly ground surfaces. Braid angle and percent coverage are.
