 A string of casing for a distinct application is designed around the anticipated operating situations.The operating situations (internal and external pressure, tension) produce loads around the casing, and also the casing string should be capable to withstand these loads with no failure.To perform a casing string design, the operational loads are compared to the minimum efficiency properties, as well as the parameters of your casing selected such that the minimum efficiency properties are greater than the expected loads.

The designer need to take into account: the internal operating stress against the casing’s burst rating or the connection leak resistance; the external operating stress against the casing’s collapse resistance; and, the tensile loads, typically from the casing’s own weight, against the joint strength. As pressures are normally described as radients (kPa/m or psi/ft.) and the weight from the casing string is described as some mass per unit length (kg/m or lb./ft.), the operational loads

at a provided depth could be readily determined. Alternately, actual values of the expected loads may well be known and compared against the the tabulated minimum performance properties.

The operational limits on the casing is going to be governed by one of many following:

oint power - possibly fracture or pull-out

Collapse resistance

Burst resistance or connection leak resistance

For that reason, after the restricting operational situation is determined, the most functioning depth on the casing string can be calculated depending on that situation.

All tensile, burst, and collapse ratings are based on minimum efficiency properties and do not contain any safety aspects. Safety variables should be integrated when figuring out functioning pressures and permissible tensile loads.

The setting depth calculated is based on the minimum worth determined by the collapse, burst, or joint strength limitations from the distinct mixture of size/weight/grade/connection. A collapse and burst gradient of 11.3kPa/m (0.50psi/ft.), or an equivalent mud weight of 1,000kg/m3 (9.625ppg) ¨C fresh water ¨C is assumed. In

these calculations, a Safety Factor of 1.0 is utilized for burst and collapse, plus a Safety Issue of 1.six is made use of primarily based on joint strength

    How long is the life of a spiral steel pipe ?

    Spiral steel pipe itself has no life limit, and the service life is mainly related to the operating environment and production process. Spiral steel pipe operating environment is relatively poor In order to extend the service life, the oute.
