It is not, however, within the scope of this recommended practice to provide detailed suggestions for corrosion control appi speci? Literature on external casing corrosion or persons competent in this? Material which has neither been damaged in shipment nor shipped in error requires prior authorization and may be subject to a shipping and handling charge. For example, cements or locking attachments might be used rather than welding bottom joints to prevent them from unscrewing.
To prevent galling when making connections in the? Compounds other than API modi?
zpi Avoid rough handling which might damage the threads or ding or dent the body of the pipe. The length of each piece of casing shall be measured prior to running.
Before stabbing, liberally apply thread compound to the entire internally and externally threaded areas. In order to do this, make up the? This document was produced under API standardization procedures that ensure appropriate noti?
Place clean protectors on? They should be retightened with tongs before? When rolling down skids, roll pipe aapi to the stack and do not allow pipe to gather momentum or to strike the apl, because even with thread protectors in place there is danger of damaging the threads.
Questions concerning the interpretation of the content of this standard or comments 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. The formulation and publication of API standards is not intended in any ali to inhibit anyone from using any other practices. The procedure should be reversed for disassembly.
Leak resistance is obtained by the joint itself.

The length of each piece of casing shall be measured prior to running. Inhibitor effectiveness can also be checked by means of coupons, caliper surveys, and visual examinations of readily accessible pieces of equipment.
If rubber hose is used, it is recommended that the quickclosing valve be mounted where the hose is connected to the mud line, rather than at the outlet end of the hose.
Stands of tubing sizes 1. Inhibitor effectiveness may be checked also by means of caliper surveys, visual examinations of readily accessible pieces of equipment, and water analyses for iron content.
Enviado por Wagner flag Denunciar. This may loosen the couplings at the top of the string. Requests for permission to reproduce or translate all or any part of the material published herein should also be addressed to the general manager. Power tubing tongs are recommended for high-pressure or condensate wells to ensure uniform makeup and tight joints. These standards are not intended to obviate the need for apply- ing sound engineering judgment regarding when and where these standards should be utilized.
A copy of the initiating invoice must accompany each return. This a;i has the two-fold advantage of a welding under more favorable conditions, and b the weld cooling rate can be slower and more closely controlled.

Care should be taken to prevent cha? The total of the individual lengths so measured will represent the unloaded length of the tubing string. On round-thread joints, this position is to the plane of the vanish point on the pipe; on buttress-thread cas- ing, this position is to the base of the triangle stamp on the pipe; and on extreme line casing, this position is to the shoul- der on the externally threaded end. Clean protectors should be placed on the tubing before it is laid down.
Stagger adjoining lengths of pipe in the tiers an amount approximating the length of the coupling. Where welding is done on joints, the weld shall not be intended as a seal to prevent leakage but rather as a means of preventing the joint from backing off.
