Use of power tongs is necessary to obtain consistent makeup torque. Every effort has been made by the Institute to assure the accuracy and reliability of the data contained in them; however, the Institute makes no representation, warranty, or guarantee in connection with this publication and hereby expressly disclaims any liability or responsibility for loss or damage resulting from its use or for the violation of any gp, state, or municipal regulation with which this publication may conflict.

Depending on circumstances and emergency needs, gauging of the threads may be considered along with the usual wall inspection to determine? Protection criteria for casing differ somewhat from the criteria used for line pipe. Wear occurs inside the casing even though rubber protectors are applied to the drill pipe. Internal corrosion might also be due to stray electrical currents electrolysis or to dissimilar metals spi close contact bimetallic galvanic corrosion.

If the top side of the? Couplings should be removed, and both the mill-end pipe thread and coupling thread thoroughly cleaned and inspected. Pricing and availability subject to change without notice. Cracks have frequently resulted from striking the arc on casing. If external corrosion is evident, it must also be taken into account. This publication will no longer be in effect? Particular attention should be given to mitigation of ap where the probable life of subsurface equipment is less than the time expected to deplete a well.

It should not be expected that threaded connections shall gauge properly after being made up power tight, therefore minor deviations from the speci? Used tubing frequently requires inspection. Good cementing practices, including the use of centralizers, scratchers, and adequate amounts of cement to keep corrosive? Prepayment of orders shipped to these states should include applicable sales tax unless a purchaser is exempt. It is recommended that the makeup target be based on position, not torque.

Those found damaged, even slightly, should be laid aside unless satisfactory means are available for correcting thread damage.

If cracks are detected in a length of pipe during inspection and are verified to be of sufficient length to be gp by either visual, optical, or magnetic particle inspection, this joint shall be rejected and considered unfit for further service.

Several thread protectors may be cleaned and used repeatedly for this operation. If they lower unevenly, there is danger of denting the pipe or badly slip-cutting it. The use of caliper or optical-instrument inspections. To accomplish this, ductile welds free from cracks and brittle or hard spots are desired.

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

Tubing reconditioning should be done only in accordance with API specifications. 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.

Anticipate that maximum torque values could be? Engine Oil Licensing and Certification System? They may be 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.

When rolling down skids, roll pipe parallel to the stack and do not allow pipe to gather momentum or to strike the ends, because even with thread protectors in place there is danger of damaging the threads.

Suggested revisions are invited and should be submitted to the general manager of the Upstream Segment, American Petroleum Institute, L Street, N. As with standard couplings, makeup positions shall govern. Casing and tubing wear metal loss and corrosion usually occur on the inside surface. Some users have found that, for a limited number of critical well 5×1, these procedures do not result in casing suf?

Any manufacturer marking equipment or materials in conformance with the marking requirements of an API standard is solely responsible for complying with all the applicable requirements of that standard.

Due to the permissible tolerance on the outside diameter immediately behind the tubing upset, the user is cautioned that dif? Welds should be cleaned between passes. 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. Cracks and brittle areas are likely to develop in the heat-affected zone. Back out the connection noting torque and check threads for galling.


The spider must be level. When lengths of casing are inadvertently dragged in the dirt, the threads should be recleaned and serviced r; as outlined in 4.

Tubing inspection and handling

These standards are not intended to obviate the need for apply- ing sound engineering judgment regarding when and where these standards should be utilized. Therefore, in wells where leak resistance is not a great factor, minimum?

API Recom- mended Practice 51c provides a recommended practice for calculating performance properties of used drill pipe. Low-hydrogen electrodes should not be exposed to the atmosphere until ready for use. For these reasons, welding on high-strength casing should be avoided if possible.

API does not represent, warrant, or guarantee that such prod- ucts do in fact conform to the applicable API standard.

Use this section to provide links to relevant material on websites other than PetroWiki and OnePetro. The torque values listed in Table 1 pai to casing with zinc-plated or phosphate-coated couplings.

The type of metal loss may influence the application of used casing and tubing. Similarly, use of mechanical means for attachment of centralizers and scratchers is encour- aged. Some users have found that, for a limited number of critical well applications, these procedures do not result in tubing suf? Questions concerning the interpretation of the content of this standard or com- ments and questions concerning the procedures under which this standard was developed should be directed in writing to the general manager of the Upstream Segment, American Petroleum Institute, L Street, N.

Drill pipe wear usually occurs on the outside surface and, conse- quently, the performance properties of used drill pipe are based on a constant ID, and the wall thickness and Pr vary with the degree of wear. Care shall be taken to avoid crossthreading in starting these larger connections.

It is advisable when starting to run casing from each particular mill shipment to make up suf?
