When rolling pipe, on the rack, keep pipe parallel and do not allow pipe to gather momentum or to strike the ends.

Thread protectors must be installed properly and rough handling avoided. Both the inside and outside of tubing can be damaged by corrosion. Thread compound 55c1 be applied to both the external and internal threads, and the coupling should be reapplied handling tight.

Before 5cc1 or unloading make sure that the thread protectors are tightly in place. Connectors used as tensile and lifting members should have their thread capacity carefully checked to ensure that the connector can safely support the load.

The tp line attachment to the backup post should be corrected, if necessary, to be level with the tong in the backup position so as to avoid uneven load distribution on the gripping surfaces of the casing. Galling resistance of threads is primarily controlled in two areas—surface preparation and? Check spider slips to ensure they will not damage the tubing body.

Class IV connections are intended for the most severe application, and Class I connections are intended for the least severe application. The length of each piece of casing shall be measured prior to running. API standards are published to facilitate the broad availability of proven, sound engineering and operating practices.


This docum ent was reproduced from an authorized download of an API standard on M ay 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.

Each corrosion problem must be treated as an individual case and a solution attempted in the light of the known corrosion factors and operating conditions. API does not represent, warrant, or guarantee that such products do in fact conform to the applicable API standard.

In this manner, ends are welded without either striking or breaking the arc at the ends. They should be retightened with tongs before?

Buttress connections with PTFE seal rings may make up at torque values different from those apo observed on standard buttress threads. Excess doglegs in devi- 4.

If the bottom of the car is uneven, the stringers should be rigidly shimmed so that their tops will be in the same plane. Clean protectors should be placed on the tubing before it is laid down. 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.

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

The power tong should be provided with a reliable torque gauge of known accuracy. The use of highly alkaline mud or mud treated with a bactericide as a completion? Before stabbing, liberally apply thread compound to the entire internally and externally threaded areas.


Torque values obtained by taking 1 percent of the calculated pullout value were found to be generally comparable to values obtained by? Inspection of tubing when received and following use are important to ensure that defects or wear do not prevent the tubing from performing as designed. Requests for permission to reproduce or translate all or any part of the material published herein should also be addressed to the general manager.

The use of power tongs for making up appi made desirable the establishment of recommended torque values for each size, weight, and grade of tubing.

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

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. As a result, unless precautions are taken welding may have adverse effects on many of the steels used in all grades of casing, especially J55 and higher.

Torque values higher than those listed above may be considered under certain conditions, providing box swelling does not occur. API-modified thread compound generally has been accepted for a wide range of service conditions over many years. This document was produced under API standardization procedures that ensure appropri- ate notification and participation in the developmental process and is designated as an API standard.
