The following guidelines are suggested for inspection normally at the well location:. The operating personnel should ensure that good practices are followed. If the standoff is abnormally great, check the coupling for tightness. Shoejoint welding of couplings, when necessary, shall be used with extreme caution and with full use of procedures outlined herein. Corrosion is generally due to the corrosive well? The owner of pipe which requires special handling requirements should notify his service providers of the applicable special handling requirements and to which pipe the special requirements are applicable.

These values may indicate that a departure from the values listed in Table 1 is advisable. Two passes are preferred. If needed, adjust torque and repeat.

If other values are chosen, the minimum torque should be not less than 75 percent of the value selected. In this type of completion, especially in pumping wells, fp 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.


MCR Casing and tu Apply a good thread compound but avoid excessive amounts.

Each corrosion problem must be treated as an individual apo and a solution attempted in the light of the known corrosion factors and operating conditions. This standard is under the jurisdiction of the API Committee r Standardization of Tubular Goods and includes items approved by the letter ballot through Drill pipe wear usually occurs on the outside surface and, conse- quently, the performance properties of used drill pipe are based on a constant ID, and the wall thickness and OD vary with the degree of wear.

The maximum torque should be not more than percent of the selected torque.

Or see the online interactive version of the catalog on our web site at www. Enviado por Wagner flag Denunciar. It should not be expected that dp connections shall gauge properly after being made up power tight, there- fore minor deviations from the specified tolerances should be accepted. To determine the value and effectiveness of the above practices and measures, cost and equipment-failure records can be compared before and after application of control measures.

Galling is always a possibility that may be encountered while breaking out connections, particularly when backups are placed on the coupling.

API RP 5C1 Recommended Practice for Care and Use of Casing and Tubing

Hard areas or cracks may cause failure, especially when the casing is subjected to tool-joint battering. In this manner, ends are welded without either striking or breaking the arc at the ends.

If the connection does not shoulder when spi torque is applied, it should ro treated as a questionable joint as provided under 4. The use of pipe wrenches is not recommended. The following are also checked:. This gives a bending effect that tends to gall the threads.


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. The measurement should be made from the outermost face of the coupling or box r the position fp the externally threaded end where the coupling or the box stops when the joint is made up power tight.

Care should be taken to prevent cha?

Do not overload truck to the point where there is any danger that the load cannot be delivered to its destination without unloading. Avoid hitting casing against any part of derrick or other equipment. The arc should be struck on the attachment, appi is made from steel not as susceptible to damage.

If damaged or out-of-tolerance threads are not found to be the cause of improper makeup, then the makeup torque should be adjusted to obtain proper makeup see 4. Do not ground to the rack but? Status of the publication can be ascertained from the API Upstream Segment [telephone ]. Carefully inspect the threads. The intent here is to outline practices that will serve as a guide to?

Familiarize himself with inspection practices speci? Care shall be taken to avoid crossthreading in starting these larger connections. Ro condition of the casing can be determined by visual or optical-instrument inspections.

Dropping a string even a short distance may loosen couplings at the bottom of the string.
