Tubing should be stacked on racks following proper procedures, and tubing in storage should be inspected periodically and protected ai corrosion. Each problem shall be treated individually, and the solution shall be attempted in light of known factors and operating conditions.

The purpose of the welds is to make attachments or to prevent joints from unscrewing. Steels most suitable for field welding do not have these performance properties. For example, if 6 inches millimeters of weld have been deposited as a stringer bead from left to right, then the operator should start about 6 inches millimeters to rpp left of the weld deposited and weld up to the starting point of the previously deposited weld.

API RP 5C1 Archives – Production Technology

The concentration of H2S necessary to cause cracking in different strength materials is not yet well de? Nothing contained in any API publication is to be construed as granting any right, by implication or otherwise, for the manufacture, sale, or use of any method, apparatus, or product covered by letters patent.

In addition to the body wall loss classi? It is also recommended that at least one other discharge connection 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. Tubing can be damaged during shipment, at the wellsite, and during running and pulling.


Place a clean thread protector on the? The following are also checked:. This document was produced under API standardization procedures that ensure appropriate noti? It should be noted that a thread compound with a coef? Check spider slips to ensure they will not damage the tubing body. These inspection techniques are limited to location of cracks, pits, and other surface imperfections. For purposes of safety, ease of inspection, and handling, pipe should not be stacked higher than 10 feet millimeters.

Physical properties are checked and each length hydrostatically tested, normally to only 3, psi in the plain end unthreaded condition. 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 c51 evaluated by the pipe owner.

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

Serious consideration should be given before using such casing in a position in the string where a heavy tensile load is imposed.

When making up round-thread connections with PTFE polytetra? When using a spinning line, it is necessary to compare hand tightness with spin-up tightness.

These standards are not intended to obviate the need for apply- ing sound engineering judgment regarding when and 51 these standards should be utilized.

Generally, API standards are reviewed and revised, reaffirmed, 51 withdrawn at least every five years. Place spacing strips at right angles to pipe and directly above the lower strips and supports to prevent bending of pipe.

If exempt, please print your state rl number and enclose a copy of the current exemption certificate. Weaving should be kept to a minimum, and the current should be on the low side of the range recommended by the electrode manufacturer.

Service induced defects considered to be representative of defects associated with used pipe inspection are as follows: If returns are due to processing or shipping errors, API will refund the third class postage. Do not unload pipe by dropping.


Keeping a space of one-third to one-quarter of the diameter of the pipe between the tong and the coupling should normally prevent unnecessary friction in the threads. They may make into a coupling on the next makeup but would not have the anticipated joint strength and could have inadequate leak resistance. Pipe with pits may not be used under some corrosive conditions but may perform satisfactorily where corrosion is not a factor.

After stabbing, the casing should be rotated very slowly at? Water analyses to determine the iron content before and after starting the inhibitor treatment may also serve as an indication of the comparative rates of corrosion. The welding cable should not be grounded to steel derrick, rotary-table base, or casing rack. Adequate thread cleaning is essential for proper connection makeup and pressure-tight strings. The thread compound also provides the lubrication to deter galling.

Sometimes a one-time extension of up to two years will be added to this review cycle. It is good practice to strike the arc near the lug end, weld the end, and bring the weld back to about the lug center. For additional copies or licensing options, contact Techstreet, Inc.
