Engineering

Engineering is a field of activity that includes the whole range of services for the development and implementation of innovative objects.
Constanta-2 LLC, having many years of experience in the development of sealing equipment, as well as research in the field of hermetic sealing, offers its customers a range of services for the design, manufacture, seals, sealing units of pipeline valves, pumps, hydraulic and pneumatic devices using the latest achievements of hermetology. It includes assessment of operating conditions and risks that the object of design is exposed to from external and internal factors, construction of 3D models, calculation of effective stresses and deformations by the finite element method, selection of the most suitable material for these purposes from the database of Constanta-2 LLC, correction of the 3D model and seals and sealing unit, manufacturing of the prototype with the help of additive technologies, testing the performance of the unit on the stand for hydraulic or pneumatic tests.

Algorithm for selecting a seal material

As part of the development process the economic analysis of the assembly or design is carried out according to the following algorithm.

Factors determining competitiveness of valves

Constanta-2 LLC has intellectual and production resources for engineering in the field of industrial equipment corrosion protection for metallurgical, power and chemical industries.

An intermediate justification of works and estimation of the expected costs of material and human resources is formed on the basis of the analysis of the technical specification or object inspection using the given algorithm. The expediency of anticorrosion protection is assessed in cooperation with the customer. A project of works production is developed on the basis of selection of materials and scheme of anticorrosion protection and taking into account existing environmental requirements and normative base on labour protection and safety. At the same time, a conclusion on the service life of the corrosion protection system is issued.
