When lengths of casing are inadvertently dragged in the dirt, the threads should be recleaned and serviced again as outlined in 4. Both spider and elevator slips should be clean and sharp and should?

Tubing inspection and handling

Slips should be extra long for heavy casing strings. The spider must be level. Slip and tong marks are injurious. Every possible effort should aoi made to keep such damage at a minimum by using proper up-todate equipment.

If they lower unevenly, there is danger of denting the pipe or badly slip-cutting it. Tongs may be sized to produce 1. Tongs should be examined for wear on hinge pins and hinge surfaces. The backup 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.

The length of the backup line should be such as to cause minimum bending stresses on the casing and to allow full stroke movement of the makeup tong. Immediately before running, remove thread protectors from both? Carefully inspect the threads. Those found damaged, even slightly, should be laid aside unless satisfactory means are available for correcting thread damage. The length of each piece of casing shall be measured prior to running.

A steel tape calibrated in decimal feet millimeters to the nearest 0. The measurement should be made from the outermost face of the coupling or box to the position on the externally threaded end where the coupling or the box stops when the joint is made up power tight.

On round-thread joints, this position is to the plane of the vanish point on the pipe; on buttress-thread casing, this position is to the base of the triangle stamp on the pipe; and on extreme line casing, this position is to the shoulder on the externally threaded end. The total of the individual lengths so measured will represent the unloaded length of the casing string.

The actual length under tension in 5c11 hole can be obtained by consulting graphs that are prepared for this purpose and are available in most pipe handbooks. Check each coupling for makeup. If the standoff is abnormally great, check the coupling for tightness. 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. Before stabbing, liberally apply thread compound to the entire internally and externally threaded areas.

It is recommended that a thread compound that meets the performance objectives of API Bulletin 5A2 be used; however, in special cases where severe conditions are encountered, it is recommended that high-pressure 5×1 thread compounds as speci?

Place a clean thread protector on the? Several thread protectors may be cleaned and used repeatedly for this operation. If a mixed string is to be run, check to determine that appropriate casing will be accessible on the pipe rack when required according to program.

Connectors used as tensile and lifting members should have their thread capacity carefully checked to ensure that the connector can safely support the load.

Care should be taken when making up pup joints and connectors to ensure that the mating threads are appi the same size and type. Casing that will not 5v1 the drill test should be laid aside. Use rope snubber if necessary. Avoid hitting casing against any part of derrick or other equipment. Provide a hold-back rope at window.

The brush or utensil used in applying thread compound should be kept free of foreign matter, and the appi should never be thinned.

Stab vertically, preferably with the assistance of a man on the stabbing board. If the casing stand tilts to one side after stabbing, lift up, clean, and correct any damaged thread with a three-cornered? After stabbing, the casing should be rotated very slowly at? If spinning line is used, it should pull close to the coupling.

For recommendations on makeup of casing with spinning lines and conventional tongs, see 4. Because of this, it is essential that torque be related to madeup position as outlined in 4. The torque values listed in Table 1 apply to casing with zinc-plated or phosphate-coated couplings.

When making up connections with tin-plated couplings, 80 percent of the listed value can be used ai a guide. The listed torque values are 51c applicable for making up couplings with PTFE polytetra? When making up round thread connections with PTFE rings, 70 percent of the listed values are recommended.

Buttress connections with PTFE seal rings may make up at torque values different from those normally observed on standard buttress threads. Thread galling of gall-prone materials martensitic chromium steels, 9 Cr and 13 Cr occurs during movement—stabbing or pulling and makeup or breakout.

Galling resistance of threads is primarily controlled in two areas—surface preparation and? Threads and lubricant must be clean. Assembly in the horizontal position should be avoided. Connections should be turned by hand to the hand-tight position before slowly power tightening. The procedure should be reversed for disassembly. It is advisable when starting to run casing from each particular mill shipment to make up apj These values may indicate that a departure from the values r in Table 1 is advisable.

If other values are chosen, the minimum torque should be not less than 75 percent of the value selected. The maximum torque should be not more ep percent of the selected torque. The power tong should be provided with a reliable torque gauge of known accuracy.

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. To prevent galling when making up connections in the?

Continue the makeup, observing both the torque gauge and the approximately position of the coupling face with respect to the thread vanish point position. The torque values shown in Tables 1, 2, and 3 have been selected to give recommended makeup under normal conditions and should be considered as satisfactory providing the face of the coupling is? If the makeup is such that the thread vanish point is buried two thread turns and 75 percent of the torque 4.

Early studies and tests indicated that torque values are affected by a large number of variables, such as variations in taper, lead, thread height and thread form, surface? In view of the number of variables and the extent that these variables, alone or in combination, could affect the relationship of torque values versus made-up position, it was evident that both applied torque and made-up position must be considered.
