Control Line calculations

Sandvik's control line calculator is a tool that provides estimates of the highest permissible internal pressure for control lines of certain sizes and Sandvik grades. You can choose between the three formulas, several outer diameter and wall thicknesses, the option of seamless or welded and the well temperature.

Based on your inputs, the available material grades will be displayed along with their internal yield pressure (psi) and burst pressure (psi). You can update or change the parameters as many times as you like, on your preferred devise. The result of each calculation is presented as an approximate maximum working pressure.

Due to the differences in national regulations, this type of calculations differs from country to country, and many limitations exist. We have therefore chosen to present the following standards

ASME B31.1

ASME B31.1 prescribes minimum requirements for the design, materials, fabrication, erection, test, inspection, operation, and maintenance of piping systems typically found in electric power generating stations, industrial and institutional plants, geothermal heating systems, and central and district heating and cooling systems.

It also covers boiler-external piping for power boilers and high-temperature, high pressure water boilers in which steam or vapor is generated at a pressure of more than 15 psig; and high temperature water is generated at pressures exceeding 160 psig and/or temperatures exceeding 250 degrees F.

ASME (American Society of Mechanical Engineers) offers a continuously evolving portfolio of standards across a wide range of topics, including pressure technology, power plants, elevators, construction equipment, piping, nuclear components, and many more.

LAME

In mathematics, a Lamé function, or ellipsoidal harmonic function, is a solution of Lamé's equation, a second-order ordinary differential equation. It was introduced in the paper (Gabriel Lamé 1837). Lamé's equation appears in the method of separation of variables applied to the Laplace equation in elliptic coordinates. In some special cases solutions can be expressed in terms of polynomials called Lamé polynomials.
