Since corrosion may result from many causes and in? Engine Oil Licensing and Certification System? Pipe having more uniform metal loss r mechanical wear should be less vulnerable to corrosive conditions and needs only to be derated for the min- imum remaining wall thickness.

When unloading by hand, use rope slings to control the pipe. Small pits or other localized metal loss may not be damaging depending on the application of the pipe, but this type of metal loss should be considered and evaluated by the pipe owner. Use this section to list papers in OnePetro 5d1 a reader who wants to learn more should definitely read.

Tubing inspection and handling

If external corrosion is evident, it must also be taken into account. Severe corrosion may also be caused by sulphate-reducing bacteria. A steel tape calibrated in decimal feet millimeters to the nearest 0.

In addition to the body, the tubing upset and threads often require inspection, typically by magnetic powder and use of thread gauges. Tubing should be stacked on racks following proper procedures, and tubing in aoi should be inspected periodically and protected from corrosion.

API standards are published to facilitate the broad availability of proven, sound engineering and operating practices. 55c1 temperature should be maintained during welding. Bad contact may cause sparking, with resultant hard spots beneath which incipient cracks may develop. The use of pipe wrenches is not recommended.

Do not jump tubing out of the coupling. Various nondestructive inspection services have been employed by users to ensure that the rrp quality of tubing is being run.

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

Both the inside and outside of tubing can be damaged by corrosion. Serious consideration should be given before using such casing in a position in the string where a heavy tensile load is imposed. These standards are not intended to obviate the need for apply- ing sound engineering judgment regarding when and where these standards should be utilized.

Material which has neither been damaged in shipment nor shipped in error requires prior authorization and may be subject to a shipping and apii charge.

API standards are published to facilitate the broad availability of proven, sound engineer- ing and operating practices. Pipe body will not pass drift test One green paint band approxi- mately 2 inches wide at the point of drift restriction and adjacent to the color band denoting body wall classification.

Damaged threads may leak or part. Do not pile pipe directly on ground, rails, and steel or concrete?

Pipe in storage should be inspected periodically and protective coatings applied when necessary to arrest corrosion. After the load has been hauled a short distance, retighten load-binding chains loosened as a result of the load settling.

It is also recommended that at least one other discharge apo be left open on the mud system to prevent buildup of excessive pressure when the quick-closing valve is closed while the pump is still running. Collar-type tubing elevators are adequate for API nonbeveled couplings; however, slip-type elevators are recommended when running tubing with beveled couplings, special clearance couplings, and integral joint tubing.

Physical properties are checked and each length hydrostatically tested, normally to only 3, psi in the plain end unthreaded condition. Steels most suitable for field welding do not have these performance properties. The adequacy of the original tension safety factor of the string as designed will in? These standards are not intended to obviate the need for applying sound engineering judgment regarding when and where these standards should be utilized.

The welding cable should not be grounded to steel derrick, rotary-table base, or casing rack. Use this section to provide links to relevant material on websites other than PetroWiki and OnePetro.

Ground wire should be? Galling is always a possibility that may be encountered while breaking out connections, particularly when backups ap placed on the coupling. It should be noted that a thread compound with 5d1 coef? Place spacing strips at right angles to pipe and directly above the lower strips and supports to prevent bending of pipe.

Hard areas or cracks may cause failure, especially when the casing is subjected to tool-joint battering. They may apk used to avoid brittle areas or cracks that may occur in alloy casing when welded; but when so subjected to this temperature, a reduction in strength may result.

For example, cements or locking attach- ments might be used rather than welding bottom joints to pre- vent them from unscrewing.
