Techniseal

Main Features:

• metal to metal gas tight seal (for tubing: 30° seal angle, for casing: 10% taper seal)
• improved Buttress thread profile resistant to galling
• a relief gap between pin crest and box root assures a flow path along the connection, thus avoiding the generation of potential pressure peaks and thus a potential early connec- tion failure and its sealing capacity due to trapped thread compound
• coupling outside diameter often smaller than comparable sizes as per API specifications
• the streamlined internal profile of the connection provides a constant transition between pin and box, helping to avoid turbulence, pressure losses and contributes to reduce the risk of corrosion to a minimum
• long middle fillet inside the coupling allows for good stress distribution in the joint
• joint tension efficiency of 100% with respect to the pipe body in the majority of usual applications*
• superb make up properties due to wide and well defined torque values
• superb make up properties due to wide and well defined torque values
• For special requirements, technical modifications to the standard requirements are available

* except for some heavy wall casing
