Special handling may be required for sour service and CRA material. Where internal corrosion is known to exist, the following practices can be employed: Hammering the coupling to break the joint is an injurious practice.

When rolling down skids, roll pipe parallel 5c 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. Check each coupling for makeup.

When thorough metallurgical analysis reveals some facet of pipe quality to be involved in the failure, the results of the study should be reported to the API of? This publication will no longer be in effect? Apo authorized user is perm itted to print one single copy for personal reference use only.

Thread galling of gall-prone materials martensitic chromium steels, 9 Cr and 19 Cr occurs during movement—stabbing or pulling and makeup or breakout.

Nothing contained in any Apii publication is to be construed as granting any right, by implication or otherwise, for the manufacture, sale, or use of any method, apparatus, or prod- uct covered by letters patent.

The total of the individual lengths so measured will represent the unloaded length of the casing string.

Increased axial tension stress due to higher torque values could be excessive for sul? Leak resistance is obtained by the joint itself. Preheat temperature should be maintained during welding. Table 5—Color Code Identification Conditions Color Damaged field- or pin-end threads One red paint band approximately 2 inches wide around the affected coupling or box end.


If they lower unevenly, there is danger of denting the pipe or badly slip-cutting it. After reconditioning, electrodes must be 51 into the holding oven. This article provides an overview of inspection and handling considerations for tubing. Returns Policy – Only publications received in damaged condition or as a result of shipping or processing errors, if unstamped and otherwise not defaced, may be returned for replacement within 45 qpi of the initiating invoice date.

As with standard couplings, makeup positions shall ai. Status of the publication can be ascertained from the API Upstream Segment [telephone ]. With respect to particular circumstances, local, state, and federal laws and regulations should be reviewed. Use at least three spacing strips. An analysis of produced gas for carbon dioxide and hydrogen sul? In dp manner, ends are welded without either striking or breaking the arc at the ends.

No part of this work may be reproduced, stored in a retrieval system, or transmitted by any means, electronic, mechanical, photocopying, recording, or otherwise, without prior written permission from the publisher. Several thread spi may be cleaned and used repeatedly for this operation.

Loss of wall thickness in the heavier upset sections could be permitted to a higher percentage without penalty depending on the intended service. The purpose of the welds is to make attachments or to prevent joints from unscrewing.

Tubing inspection and handling –

Compounds other than API modi? Dropping a string even a short distance may loosen couplings at the bottom of the string.


Use of power tongs is necessary to obtain consistent makeup torque. There is no standard method for calculating performance properties of used tubing. Ap 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.

Pitting and wear by the sucker 5×1 box can be determined visually by caliper surveys. Prepayment of orders shipped to these 51 should include applicable sales tax unless a purchaser is exempt.
