Ensuring Safety at Pneumotest of the Pipeline

Abstract

Ufa state petroleum technological university, Institute of Petroleum Technology and New Materials of Republic of Bashkortostan, Ufa, Russian Federation Аннотация. В работе рассматриваются основы обеспечения © Электронный научный журнал «Нефтегазовое дело». 2017. №4 http://ogbus.ru establishment of thermodynamic equilibrium, the translational, rotational, for molecular gases even and vibrational degrees of freedom, in certain conditions, the dissociation and recombination of molecules, chemical reactions, the processes involving electrons (ionization, electronic excitation). In this paper we have investigated the dependence of the conditional probability of defeat of a man from a change in the overpressure of the shock wave of the explosion. On the basis of the conducted researches the measures to prevent the occurrence of the shock wave pneumatic tests: strict adherence to safety standards and conditions for the maintenance of pressure in the pipeline, ensure an acceptable working range of conditions of the pneumatic tests, the availability of required serviceable equipment and fittings. Ключевые слова: Пневмоиспытание, ударная волна, очаги поражения, избыточное давление.

Impact Modelling of Explosion of Mixture Explosive Charges on the Environment

“…The functional (degree) dependences of excess pressure on the distance of the source of the explosion and the charge and impulse mass on the excess pressure and the charge radius for different types of EX have been determined. 4. It has been established that with an increase in excess pressure, the impulse of the airborne shock wave increases.…”

“…In the work by Vadulina, Achyvakov and Sanimov [4], the main bases of human life insurance during the explosion of the pipeline are considered, the dependence of the conditional probability of human damage on the change in excess pressure of the shock wave of the explosion is studied. In the works [5]- [8], the influence of explosive lesions on the human organism is examined during technogenic catastrophes and terrorist acts.…”
