The throughput ability of shutoff and control valves

Ilĺgiz R. Chinjaev, Aleksandr V. Fominykh, Egor A. Poshivalov, Stanislav A. Sukhov

Calculations and experimental research of hydraulic properties of shutoff and controlvalve are presented. The throughput ability was defined based on test value at modular cluster pump station which is facility of "Bashneft- Dobycha" and in laboratory of MKT-ACDM.

Key Advantages of IEP for Factory Automation

Anastasia E. Babintseva

Design and high quality materials. For qualityToday the question of process automation is one of the most urgent in all areas of production. And, of course, the emerging trend is being sparedthe sphere of oil production and processing. This is due to the fact that this area specialists often work in places where human presence is dangerous to health protection, subject to the threat of explosions, difficult to access areas, aggressive environments, dusty field, vibrations, etc. Solution of such problems is the executive power mechanisms (IEP ), which provide complete auto mation and smooth operation processes. Electric Linear Actuators IEP designed for sustained move elements of machines, structures.

Stop valves: what to choose?

Anatoly G. Karpov, Natalya N. Shubenkina

There are different types shut-off valves. Each type was designed to solve aspecific operational tasks. However, there applications where possible to use any type of reinforcement. In this article we reviewed features choice of type valving which depending on operating conditions, thepros and cons, as well as limitations on their application.

Tender!!! What kind of emotions you have is this word?

In this article we have tried to draw attention to issues that arise from bidders in the preparation the competitive offers, to show organizers tender the look on the other hand to offer options to improve the preparation
of tender documentation, because this determines whether you or your staff to divert cases from the an endless stream of calls and letters to potential suppliers with a request to clarify the requirements. When the more fully
explained the task, more likely to get exactly what you need.
Results
The current system forming applications for tenders in many enterprises is far from ideal and does not contribute to raising the technical level of production. Requires adjustment of approaches to the formation of queries and systems evaluation in procurement to minimize the potential of a negative impact of tenders on the promotion of the latest technical solutions for the to equip the productions.
Đonclusions
If a consumer wants to buy quality goods on a tender basis, a formal approach to the formation an application is not valid. Only a complete, accurate and accurate information on future operating conditions of production will allow the customer to obtain the most appropriate technical solution to their tasks and conditions execution of the order (price
and terms). Priority such operating properties, as lifetime without service, working resource, in assessing proposals will allow the customer to purchase more quality product.

Who is to blame or what to do?

In this article we have tried to uncover all the problems that arise in the process of equipment selection for the design, repair and modernization of production facilities. Possible causes of failure of the set pipeline valves in the warranty period. Are some tips to improve the efficiency of processes of selection and use pipeline valves. Dealt with the question of selection of foreign-made pipeline valves. Recommendations are given on using consulting firms to ensure the proper selection of fittings. We have tried to uncover all the problems that arise in the process of equipment selection for the design new facilities, as well as for repair and modernization of existing facilities. To increase the effectiveness and safety facilities equipment manufacturers are used new design and technological developments that will ensure maximum adaptation to the specific operating conditions, to increase its efficiency. This equipment is highly specialized. To increase in the between-repairs period and production safety is extremely important that the equipment in industrial plants operated under conditions for which it is intended. High-quality equipment can serve absolutely not for long and do not meet the expectations of exploiting services, in the case of wrong selection or operation under the conditions (modes), inadequacy of this reinforcement. High-quality valves when properly selection and use significantly increases the efficiency, safety and reliability of production.

Problems with comparison of Russian and foreign standards for valve seat leakage

In this article is discussed the problems which can appear with conversion of information from one standards to another. For this article was used materials from GOST9544, ISO5208, ANSI FCA 70-2, DIN 3230, MSS SP-61, API598. There are given the recommendations for conversion of information from one standards to another. It's necessary to pay more attention to valve seat leakage and to standards which specify this question.

Buying expensive equipment error or good judgment?

Management of any company interested in reducing costs. You always want to save money, but it always turns out for the production of low-cost equipment fittings? This article presents the analysis of a small economic situation in the case of autoclave production, which we discussed in my previous article ôProblems of operation of autoclaves and the choice of structural materials for the manufacture of autoclave equipment manufacturesö.
Based on the working conditions of valves, pumps and pipelines, according to available statistics, manufacturers, made an assessment of their durability and the estimated cost, depending on the material from which the equipment is made.
