Therefore, field weldability shall not be of primary consideration in the selection of steel for the manufacture of casing.

API RP 5C1 Review Torque Tables WI 2356.

When ro previous experience with any of the above measures, these should be used cautiously and on a limited scale until appraised for the particular operating conditions. If external corrosion is evident, it must also be taken into account. Do not ground to the rack but? Provide ali hold-back rope at window. Thread compounds described in the latest edition of API Bulletin 5A2 should not be used on rotary shouldered connections. Back out the connection noting torque and rl threads for galling.

Each problem shall be treated individually, and the solution shall be attempted in light of known factors and operating conditions.

Place a clean thread protector on the? Leak resistance is obtained by the joint itself. When lengths of casing are inadvertently dragged in the dirt, the threads should be recleaned and serviced again as outlined in 4.

Tubing inspection and handling

This publication will no longer be in effect five years after its publication date as an operative API standard or, where an extension has been granted, upon republication. Thread compound should be applied to both the external and internal threads, and the coupling should be reapplied handling tight.

A properly designed xpi protection system similar to that used for line pipe, which can alleviate external casing corrosion. If tapping is required, use the? Torque values obtained by taking 1 percent of the calculated pullout value were found to be generally comparable to values obtained by?

Information concerning safety and health risks and proper precautions with respect to par- ticular materials and conditions should be obtained from the employer, the rpp or supplier of that material, or the material safety data sheet. Protection criteria for casing differ somewhat from the criteria used for line pipe. Two passes are preferred. Corrosion products may or may not adhere to the pipe walls.

The total of the individual lengths so measured will represent the unloaded length of the tubing string. Many variables may be involved in a speci? However, there is no standard method for calculating perfor- mance properties of used casing and tubing. Care must be taken in unloading and storage. 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.

The required cooling usually takes about 5 minutes. Tighten any loose couplings after thoroughly cleaning the threads and applying fresh compound over entire thread surfaces, and before pulling the pipe into the derrick.

Steels most suitable for? The acceptability of reconditioned threads should always be con? The length of the backup line should be such as to cause minimum bending stresses on 5cc1 casing and to allow full stroke movement of the makeup tong.

Frequently, wear occurs on only one side, that being the casing on the low side of the hole. Tubing can be damaged during shipment, at the wellsite, and during running and pulling. Other relationships may be more appropriate for individual users. For transportation, slightly different procedures are needed to prevent damage depending on whether shipped by water, rail, or truck.

Connectors used as tensile and lifting members should have their thread capacity carefully checked to fp that the connector can safely support the apk.

Hammering the coupling to break the joint is an injurious practice. In view c51 the number of variables and the extent that these variables, alone or in combination, could affect the relationship of torque values versus made-up position, it was evident that both applied torque and made-up position must be considered.

Immediately before running, remove thread protectors from both? Generally, API standards are reviewed and revised, reaffirmed, or withdrawn at least every five years. Performance properties should 5c11 based on a constant OD.

The base of the triangle will aid in locating the thread vanish point for basic power-tight makeup; however, the position of the coupling with respect to the base of the triangle shall not be a basis for acceptance or rejection of the product. All returns must be shipped prepaid using third class postage. Use this section to list papers in OnePetro that a reader who wants to learn more should definitely read.

Impact against adjacent pipe or other objects may cause a local increase in the hardness of the pipe to the extent that they become susceptible to sul? 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. Inhibitor effectiveness can also be checked by means of coupons, caliper surveys, and visual examinations of readily accessible pieces of equipment.

This standard is under the jurisdiction of the API Committee on Standardization of Tubular Goods and includes items approved by the letter appi through Joints that are questionable as to their proper makeup in 4. Ep 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.

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. Ability to withstand bending forces is also often important.

Loss of wall thickness in the heavier upset sections could be permitted to a higher percentage without penalty depending on the intended service.

Frequently, wear occurs on only one side, that being the casing on the low side of the hole. Pipe with pits may not be used under some corrosive conditions but may perform apl where corrosion is not a factor.
