The concentration of H2S necessary to cause cracking in different strength materials is not yet well de?
Rrp, use of mechanical means for attachment of centralizers and scratchers is encouraged. Stagger adjoining lengths of pipe in the tiers an amount approximating the length of the coupling. The torque values listed in Table 1 apply to casing with zinc-plated or phosphate-coated couplings. Do not jump casing out of the coupling.
Impact against adjacent pipe or other objects may cause a local increase in the hardness of the pipe to the extent that they become susceptible to sul?
Corrosion can also be in? An analysis of produced gas for carbon dioxide and hydrogen sul? The maximum torque should be not more than percent of the selected torque. In hauling long pipe, an additional chain should be provided in the middle. Used tubing should be classified according to loss of nominal wall thickness. API does not represent, warrant, or guarantee that such products do in fact conform to the applicable API standard.
Dirty threads, or threads contaminated with coating material used as protection from corrosion. Where these are not practical, a casing-caliper survey can be made to determine the condition of the inside surfaces. As a result, unless precautions are taken welding may have adverse effects on many of the steels used in all grades of casing, especially J55 and higher.
API RP 5C1 Recommended Practice for Care and Use of Casing and Tubing
Do not be misled, by stretching of the tubing string, into the assumption that the tubing rl free. This publication will no longer be in effect five years after its publication date as an operative API standard or, where an extension has been granted, upon republication. For purposes of safety, ease of inspection, and handling, pipe should not be stacked higher than 10 feet millimeters.
Carefully inspect the threads. Inhibitor effectiveness may be checked also by means of caliper surveys, visual examinations of readily accessible pieces of equipment, and water zpi for iron content. Use this section to provide links to relevant material on websites other than PetroWiki and OnePetro.
55c1 Care should be taken when making up pup joints and connectors to ensure that the mating threads are of the same size and type. Familiarize himself with inspection practices speci?
Corrosion products may or may not adhere to the pipe walls.
Tubing inspection and handling –
In such cases, there are certain practices that, if followed, will minimize the deleterious effects of welding. The formulation and publication of API standards is not intended in any way to inhibit anyone from using any other practices. This procedure has the two-fold advantage of a welding under more favorable conditions, and b the weld cooling rate can be slower and more closely controlled. Every possible effort should be made to keep such damage at a minimum by using proper up-todate equipment.
Before stabbing, liberally apply thread compound to the entire internally and externally threaded areas. Due to the permissible tolerance on the outside diameter immediately behind the tubing upset, the user is cautioned that dif? Service induced defects considered to be representative of defects associated with used pipe inspection are as follows: Depending on circumstances and emergency needs, gaug- ing of the threads may be considered along with the usual wall inspection to determine final performance properties.
Preheat temperature should be maintained during welding.
Tubing inspection and handling
There is no standard method ep calculating performance properties of used tubing. Assembly in the horizontal position should be avoided. Corrosion is generally due to the corrosive well? Ability to withstand bending forces is also often important.
MCR Casing and tu Setting the casing with improper tension after cementing is one of the greatest contributing causes of such failures.

API standards are published to facilitate the broad availability of proven, sound engineering and operating practices. The damage is generally in the form pr pitting, box wear, stress-corrosion cracking, and sul?
