This gives a bending effect that tends to gall the threads. It is advisable when starting to run casing from each particular mill shipment to make up suf? Load pipe with all couplings on the same end of the truck. In order to do this, make up the? Information concerning safety and health risks and proper precautions with respect to particular materials and conditions should be obtained from apl employer, the manufacturer or supplier of that material, or the material safety data sheet.
Suggested revisions are invited and should be submitted to the general manager of the Upstream Segment, American Petroleum Institute, L Street, N. These percentages represent reductions in the body wall from the API speci?
Tubing inspection and handling –
Customer Daytime Telephone No.: When unloading by hand, use rope slings to control the pipe. For more complete technical information on speci? Two pass welds are preferred, provided the second pass may be controlled so that it shall overlay only the weld metal and not extend to the casing. All values are rounded to the nearest 10 ft-lb Wear occurs inside the casing even though rubber protectors are applied to the drill pipe. Do not unload pipe by dropping.
Two passes are preferred. Increased axial tension stress due to higher torque values could be excessive for sul?
Also desirable is an analysis of the ef? The tongs selected should be capable of attaining high torques [50, ft-lb 67, N? Pulling too hard on string. 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.
If the tubing tilts to one side after stabbing, lift up, clean, and correct any damaged thread with a three-cornered? This condition may penalize joint strength, leak resistance, and in severe cases, lead to abutment of pin ends near the center of the coupling in the made-up connection.
If tapping is required, use the? However, there is no standard method for calculating perfor- mance properties of used casing and tubing. Damaged threads or threads that do not comply with the speci? Couplings that have been dented by hammering. Water analyses to determine the iron content xpi and after 5v1 the inhibitor treatment may also serve as an indication of the comparative rates of corrosion.
Special handling may be required for sour service and CRA material. Corrosion rate tests by using coupons of the same materials as in the well. Use this section to provide links to relevant material on websites other than PetroWiki and OnePetro.

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. The formulation and publication of API standards is not intended in any way to inhibit anyone from using any other practices. The base of the triangle will aid in locating the thread vanish point for basic power-tight makeup; however, the position of the coupling with respect to the base of the triangle shall not be a basis for acceptance or rejection of the product.
Clean protectors should be placed on the tubing before it is laid down. These values may indicate that a departure from the values listed in Table 1 is advisable. 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.
If any length cannot be clearly identi?
Performance properties should be based on a constant OD. Or see the online interactive version of the catalog on our web site at www. The torque 5cc1 listed in Table 3 apply to tubing with zinc-plated or phosphate-coated couplings. Connections should be turned by hand to the hand-tight position before slowly power tightening.
Also on repeated makeup, the threads make up more each time and interference occurs. These standards are not intended to obviate the need for apply- ing sound engineering judgment regarding when and where these standards should be utilized. Also on repeated makeup, the apl make up more each time and interference occurs. After stabbing, the casing should be rotated very slowly at? Shoejoint welding of couplings, when necessary, shall be used pr extreme caution and with full use of procedures outlined herein.
The weld is then continued around the second end, bringing the arc back on the weld before breaking. The color coding should consist of a paint band of the appropriate color approximately 2 in.

Do not ground to the rack but? If cracks are detected in a length of pipe during inspection and are verified to be of sufficient length to be identified by either visual, optical, or magnetic particle inspection, this joint shall be rejected and considered unfit for further service.
Corrosion spi also be in? Physical properties are checked and each length hydrostatically tested, normally to only 3, psi in the plain end unthreaded condition.
