Thanks to the subsidiary company KP SAG, we can handle all the necessary design calculations in-house. An experienced team of designers and computer engineers covers the service not only in the field of nuclear services, but also in the areas of the chemical and petrochemical industry, in the field of classical energy and water management facilities. Thanks to professional, calculation and design services, we can be a valuable partner for multinational nuclear companies, but also a co-partner for domestic or foreign companies that lack a responsible partner in the field of project calculations. This sector of services can also be used as a separate service, or as part of the complex management of our client’s project.

Who is KP SAG?

KRÁLOVOPOLSKÁ STRESS ANALYSIS GROUP s.r.o. was founded in 2000. It is a company made up mainly of employees of the Strength Calculations department of Královopolská RIA a.s., formerly known as Výpočtové otdeléní Královopolské strojírny Brno a.s. Královopolská SAG therefore took over all the rich and more than 40 years of experience in the field of design and calculations, on which it based its service offer. Rich experience and a wide portfolio of calculations became the reason why the union of our company ENSECO, a.s. and KP SAG was so interesting that we invested our time and effort into it. In the expansion of our services, we see room for professional and also competitive growth, by which we would make the strong name of ENSECO, a.s. they wanted to represent on the domestic and foreign markets.

We are your partner for calculations of all kinds

An experienced and highly professional team of designers, calculators, mechanical engineers, construction engineers and specialists in the field of calculations for fittings, pipes and steel structures solves all the requirements of our clients on a daily basis, from ordinary to special ones. Our partners can also use the services in this area of calculations as a separate service to complete a step that they need to be covered by an external but experienced company within the framework of project management for their customers. For customers and partners with whom we solve projects comprehensively, that is, from design to successful implementation or start-up, the coverage of calculations by KP SAG employees will be a self-evident service that they can rely on.

classical energy,
water management facilities.

Strength calculations:

pipeline systems, including storage and supporting steel structures,
pressure vessels, devices and tanks of any shape, type and size, including anchoring,
storage steel structures and platforms,
cranes, lifting devices and assembly aids,
pumps and fittings,
flange joints.

Strength calculations with load:

static,

temperature field (both stationary and non-stationary, including temperature shocks).

Strength calculations of other types:

static strength calculations,
dynamic calculations (eigenvalues and shapes even in a complex field, harmonic oscillation, development according to eigenshapes, direct integration for linear and non-linear systems),
seismic calculations for arbitrarily defined excitation, including the method of response spectra (mono and multispectral analysis) and calculation of the HCLPF factor,
