The purpose of the welds is to make attachments or to prevent joints from unscrewing. A copper nipple at the end of the mud apj may be used to prevent damaging of the coupling threads during the? These standards are not intended to obviate the need for applying sound engineering judgment regarding when and where these standards should be utilized. Torque values higher than those listed above may be considered under certain conditions, providing box swelling does not occur. If they lower unevenly, there is danger of denting the pipe or badly slip-cutting it.

API RP 5C – Care and Use of Casing and Tubing_百度文库

Before loading or unloading make sure that the thread protectors are tightly in place. Care should be taken qpi avoid undercutting. Dropping a string even a short distance may loosen couplings at the bottom of the string. For recommendations on makeup of casing with spinning lines and conventional tongs, see 4.

In pumping wells, avoiding the use of casing pumps. Special handling may be required for sour service and CRA material.

Because corrosion may result from so many different 5v1, no simple or universal remedy can be given for its control. Various nondestructive inspection services have been employed by users to ensure that the desired quality of 1 American Welding Society, N. Joints should be made up tight, approximately two turns beyond the hand-tight position, with care being taken not to gall the threads.

However, there is no standard method for calculating performance properties of used casing and tubing. For these reasons, welding on high-strength casing should be avoided if possible.

API is not undertaking to meet the duties of employers, manufacturers, or suppliers to warn and properly train and equip their employees, and others exposed, concerning health and safety risks and precautions, nor undertaking their obligations under local, state, or federal laws. No provision of this recommended practice shall be cause for apj of casing or tubing provided the threads are in accordance with the requirements of the latest edition of API Standard 5B.

For additional copies or licensing options, contact Techstreet, Inc. Intermediate supports may be placed in the derrick to limit bowing of the tubing.

Place a clean thread protector on the? Orders to all other countries will be sent by Airmail. Familiarize himself with inspection practices speci? Place spacing strips at right 5d1 to pipe and directly above the lower strips and supports to prevent bending of pipe.

To accomplish this, ductile welds free from cracks and brittle or hard spots are desired. When making up round thread connections with PTFE rings, 70 percent of the listed values ali recommended. When H2S is present in the well? Carefully inspect the threads.

When lengths of tubing are inadvertently 5. 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.

Therefore, in wells where leak resistance is not a great factor, minimum? When using a spinning line, it is necessary to compare 5d1 tightness with spin-up tightness.

Once removed from the holding oven, electrodes must be used within 30 minutes. Stagger adjoining lengths of pipe in the tiers an amount approximating the length 51 the coupling. When making up round-thread connections with PTFE polytetra? If the standoff is abnormally great, check the coupling for tightness.

Avoid hitting casing against any part of derrick or other equipment. It should be noted that a thread compound with a coef? These investigations should cover the following: 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.

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.

Galling is always a possibility that may be encountered while breaking out connections, particularly when backups are placed on the coupling. In the initial stages of makeup, any irregularities of makeup or in speed of makeup should be observed, since these may be indicative of crossed threads, dirty or damaged threads, or other unfavorable conditions.

Low-hydrogen electrodes should not be exposed to the atmosphere until ready for use. These include all electrodes with the AWS classi? Drill pipe wear usually occurs on the outside surface and, consequently, the performance properties of used drill aoi are based on a constant ID, and the wall thickness and OD vary with the degree of wear.

Each c51 shall be double wrapped. Suggested revisions are invited and should be submitted to the general manager of the Upstream Segment, American Petroleum Institute, L Street, N. To determine the value and effectiveness of the above practices and measures, cost and equipment-failure records can be compared before and after application of control measures.

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. The condition of the casing can be determined by visual or optical-instrument inspections. Dirty threads, or threads contaminated with coating material used as protection from corrosion.
