Status of the publication can be ascertained from the API Upstream Segment [telephone ]. If necessary to strike the arc on the casing, it should be struck in the area to be welded. Orders to all other countries will be sent by Airmail. Engine Oil Licensing and Certification System? Internal casing- caliper surveys indicate the extent, location, and severity of corrosion.
The stringers should lie in the same plane and be reasonably level and should be 51 by piers adequate to carry the full stack load without settling.
The torque values listed in Table rpp apply to casing with zinc-plated or phosphate-coated couplings. An analysis of produced gas for carbon dioxide and hydrogen sul?
API RP 5C1 Archives – Production Technology
Where internal corrosion is known to exist, the following practices can be employed: After stabbing, the casing should be rotated very slowly at? State Sales Tax — The American Petroleum Institute is required to collect sales tax on publications mailed to the following states: Tonging too high on casing, especially on breaking out.
Enviado por Wagner flag Denunciar. The function of the second pass is to temper or anneal the underlying weld and adjacent metal. All values are rounded to the nearest 10 ft-lb 10 N? They may be used to avoid brittle areas or cracks that may occur in alloy casing when welded; but when so subjected to this temperature, a reduction in strength may result.
Used tubing frequently requires inspection. Cracks and brittle areas are likely to develop in the heat-affected zone. Depending on circumstances and emergency needs, gauging of the threads may be considered along with the usual wall inspection to determine? An analysis of the produced gas for carbon dioxide and hydrogen sul? In-service welds are called upon to withstand impact, pounding, vibration, and other severe service apii to which casing is subjected.
Tubing inspection and handling
For example, cements or locking attach- ments might be used rather than welding bottom joints to pre- vent them from unscrewing. It should not be expected that threaded connections shall gauge properly 5c11 being made up power tight, there- fore minor deviations from the specified tolerances should be accepted.
Care should be taken to prevent cha? Provide wooden strips as separators between successive layers of pipe so that no weight rests on the couplings. Do not jump casing out of the coupling. Information concerning safety and health risks and proper precautions with respect to par- ticular materials and conditions should be obtained from the employer, the manufacturer or supplier of aip material, or the material safety data sheet.
Use of power tongs is necessary to obtain consistent makeup torque. In hauling long pipe, an additional chain should be provided in the middle.
The amount of wear increases with the length of time the casing is drilled through. Casing and tubing wear metal loss and corrosion usually occur on the inside surface. Because corrosion may result from so many different conditions, no simple or universal remedy can be given for its control. 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.
API Recom- mended Practice 7G provides a recommended practice for calculating performance properties of used drill pipe. A fast thread lead at the area of last thread rpp of round threads would indicate that the threads became stretched when pulled at loads exceeding the yield strength of the connection. If the casing stand tilts to one side after stabbing, lift up, clean, and correct any damaged thread with a three-cornered?
They may make into a coupling on the next makeup but would not have the anticipated joint strength and could have inadequate leak resistance.

In this type of completion, especially in pumping wells, better operating practices can also aid in extending the life of tubing, such as through the use of rod protectors, rotation of tubing, and longer and slower pumping strokes. Using inhibitors to protect the inside of the casing against corrosion. Any manufacturer marking equipment or materials in conformance with the marking requirements of an API standard is solely responsible for complying with all the applicable requirements of that standard.
Name As It Appears on Card: 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. Some users have found that, for a limited number of critical well applications, these procedures do not result in tubing suf?
Place clean protectors on? These values may indicate that a departure from the values listed in Table 1 is advisable. The string should be pulled and rerun, examining all joints very carefully. Because of this, it is essential that torque be related to madeup position as outlined in 4. Depending on circumstances and emergency needs, gaug- ing of the threads may apk considered along with the usual apu inspection to determine final performance properties.
