Failures due to corrosion in oil and gas mining equipment and facilities lead to a reduction in their service life and an intensification of accidents. Active and passive protection methods are used to protect various devices and metal structures from corrosion. The main purpose of the article is to develop and evaluate the effectiveness of polymer coating materials for corrosion protection of pipelines used in mining conditions, as well as various devices and metal structures.

Keywords: mining equipment, corrosion, polymer coatings, epoxy resin, butadiene-nitrile rubber, nano metal particles.

The article is devoted to the calculation of the cylinder for strength, subject to the action of internal pressure and torque. It is noted that torque loading cylinders in particular are subject to such loading. The work consists of two parts. The first part provides information on torque hydraulic cylinders. Areas of engineering are indicated where torque hydraulic cylinders are used, what kind of torque hydraulic cylinders are, and how they work are indicated. The given formulas for torque and angular velocity for single-hazard and multi-blade torque hydraulic cylinders. In the second part of the article, the stress state of the torque hydraulic cylinder is determined, analytical expressions for stresses are obtained. From the conditions of strength, the maximum pressure difference between the cavities of the torque cylinder is determined.

Keywords: hydraulic cylinder, torque hydraulic cylinder, cavity, internal pressure, torque, differential pressure, blade, voltage, strength.

Аbstract

The process of wear of the sealing units three plunger oilfield pump is considered as a continuous Markov process with no monotone implementations of failure, which corresponds to a no monotonic diffusion (DN) distribution. From the values of the reliability function, a comparative analysis of the effectiveness of the four schemes seal assemblies and selected the best of them

Keywords: probabilistic-physical model of failure, the operating performance characteristics of the product, the generalized process of degradation, and diffusion of the distribution.

Firstly it has experimentally been revealed that the reason of the anomalous properties manifestation of the viscous fluids, particularly water and these properties strengthening for anomalous fluids in the cracks is new micro-cracked effect of “microcrack-fluid”. For realization of the fractured fields development process it is recommended taking into consideration the detected micro-cracked effect in “microcrack-fluid” system. Developed a method of calculating the permeability of the environment Kсr equivalent value hск. It is proposed to develop intensification methods of action on the basis of powerful energy fields created by generators.

Keywords: crack opening, abnormal water, pressure gradient, pressure recovery time, microcrack-liquid effect.
