Tubing inspection and handling –

Several thread protectors may be cleaned and used repeatedly for this operation. The load should be tied down and properly bulkheaded to keep it from shifting.

Pipe should rest on supports properly spaced to prevent bending of the pipe or damage to the threads. Shipping on foreign orders cannot be rushed without FedEx account number. This article provides an overview of inspection and handling considerations for tubing. On round-thread joints, this c51 is to the plane of the vanish point on the pipe; on buttress-thread casing, this position is to the base of the triangle stamp on the pipe; and on extreme line casing, this position is to the shoulder on the externally threaded end.

Buttress connections with PTFE seal rings may make up at torque values different from those normally observed on standard buttress threads. Drill pipe wear usually occurs on the outside surface and, consequently, the performance properties of used drill pipe are based on a constant ID, and the wall thickness and OD vary with the degree ai wear.

The arc should be struck on the attachment, which is made from steel not as susceptible to damage. Immediately before running, remove thread protectors from both? The length of each piece of casing shall be measured prior to running. For example, cements or locking attachments might be used rather than welding bottom joints to prevent them from unscrewing.

Weldability of the various types and grades of casing varies widely, thus placing added responsibility on the welder. Improper landing practice, which produces stresses in the threaded joint in excess of the yield point.

The required cooling usually takes about 5 minutes. Load pipe with all couplings on the same end of the truck. No further reproduction is perm itted.

API RP 5C1 Recommended Practice for Care and Use of Casing and Tubing

This procedure has the two-fold advantage of a welding under more favorable conditions, and b the weld cooling rate can be slower and more closely controlled. Table 5—Color Code Identification Conditions Color Damaged field- or pin-end threads One red paint band approximately 2 inches wide around the affected coupling or box end.

To establish the correct torque for API tubing threads, make up the first few a;i to the recommended values and examine the connection. Wear occurs inside the casing even though rubber protectors are applied to the drill pipe. If any length cannot be clearly identi? All values are rounded to the nearest 10 ft-lb If the casing stand tilts to one side after stabbing, lift up, clean, and correct any damaged thread with a three-cornered?

Casing and tubing wear metal gp and corrosion usually occur on the inside surface. Both the inside and outside of casing can be damaged by corrosion, which can be recognized by the presence of pits or holes in the pipe.

Stringers should not be placed under couplings or the upset part of pipe. Protection criteria for casing differ somewhat from the criteria used for fp pipe.

The following guidelines are suggested for inspection normally at the well location:. An analysis of produced gas for carbon dioxide and hydrogen sul? Wear occurs inside casing and liners by rotation and movement of the drill string while drilling.

Immediately before running, remove protectors from both? Load pipe on bolsters and tie down with suitable chain at the bolsters. Various nondestructive inspection services have been employed by users to ensure that the desired quality of 1American Welding Society, N. The stringers should lie in the same plane and be reasonably level and should be supported by piers adequate to carry the full stack load without settling.

When H2S is present in the well? In hauling long pipe, an additional chain should be provided in the middle. Ap used as tensile and lifting members should have their thread capacity carefully checked to ensure that the connector can safely support the load.

Environmentally non-damaging thread compounds meeting API thread-compound performance requirements are available. Early studies and tests indicated that torque values are affected by a large number of variables, such as variations in taper, lead, thread height and thread form, surface?

Continue the makeup, observing both the torque gauge and the approximately position of the coupling face with respect to the thread vanish point position. Where these are not practical, a casing-caliper survey can be made to determine the condition of the inside surfaces.
