A welding method, to reduce tension due to pipe stretching, for a downhole double-walled insulated pipe is disclosed. The pipe comprises an inner tube, an outer tube, steel spacer rings and insulated material fitted filling the annular space. Special welding links the ends of inner and outer tubes, forming a flexible metallic joint, achieved through the use of filler metal with specific chemical composition during the welding process. The inner tube is heated and extended before the tube welding is performed. The welded joint is strong enough to keep the inner tube in place when it cools down, creating a tension inwards in the tube. This way, when steam flows through the tubing during the operation, the heat stretches the inner tube until the tension direction is outwards, then the tension now becomes about half of the normal tension applied to the tube welded joint with the usual welding process. |
