BOMBEIO POR CAVIDADE PROGRESSIVA PDF

Myositis ossificans progressiva : a report of two cases. Myositis ossificans progressive is rare hereditable disorder characterized progressiva heterotopic bone formation in connective tissue and muscles in association with congenital skeletal anomalies. We report the plain radiologic and MR findings of myositis ossificants progressiva in two children. One case showed discrete ossification in the right buttock, neck, and both chest walls on plain radiographs, while the other showed diffuse swelling of the left posterior neck, back, and buttock muscles, which was demonstrated on MR images.

We are a leading supplier of sucker rods, accessories and services for beam and progressive cavity pumping operations.

With a fully integrated manufacturing process, and strategically located service centers, our technologies thrive in the most challenging wells and environments. Our range of services add value through customized supply, operational, administrative and technical solutions. Full assistance in identifying the optimum string design for each particular application, using advanced simulation software.

These services are provided with the support of our global network of customer service centers and unmatched supply chain expertise. Our trained team supervises handling, thread cleaning, makeup and torque control activities, ensuring compliance with industry best practices. We can also deploy advanced hydraulic power tongs for optimal make-up operation and torque control analysis. During installation, our field engineers are trained to assist customers and address any technical doubts that arise in the field.

We offer classroom and field training services on product selection, string design, material handling and other aspects of the installation and operation of sucker rods. In our state-of-the-art laboratories, we analyze the mechanical and dimensional properties of materials, as well as the corrosion effects on them.

The resulting data is used to diagnose potential causes of failure. We assist with field surveys, customer interviews, and statistical analysis of well intervention to provide detailed technical recommendations that include string design, material selection, diagnostics, operative recommendations and training.

The X-Torque sucker rod offers increased torque capacity by incorporating a modified pin end with a larger threaded section than conventional rods. We manufacture high strength sucker rods from quality steel bars for use in high-flow wells.

Designed for beam pumping and progressive cavity pumping operations. Accessories High quality accessories with improved resistance for beam and progressive cavity pumping in every environment. Pony rods Explore. Helicoidal rod guide Explore. Slotted pup joints Explore. Sinker bars Explore. Couplings Explore. Polished rods Explore. Available for different dimensions of rods and tubings. Vast portfolio of polymeric compounds adapted to diverse string designs and well conditions.

Used in beam pumping operations. These joints allow fluids to be injected into the well through the hollow rod string. Used in progressive cavity pumping. Pony rods are used to space out the sucker rod installation.

They are available for each steel grade, rod body diameter and thread. Used in progressive cavity pumping and beam pumping. Useful tool for gas lift, injector wells, and workover operations.

Used for beam pumping. Different rod guide lengths available for a wide range of applications. Specially designed to support a flush external connection, niples withstand more torque than standard sucker rod connections.

Crossovers allow standard API-threaded accessories to be attached to hollow rods. Both are useful tools for gas lift, injector wells, and workover operations.

Other combinations can be developed upon request. Used in progressive cavity pumping operations. Slotted pup joints allow fluids to be injected into the tubing at varying depths. Used to flush away sand, control corrosion and paraffin deposition, reduce scale build-up and heavy oil viscosity.

Used both for progressive cavity pumping and beam pumping in gas lift, injector wells, and workover operations. Sinker bars are used to maintain an optimized string design in beam pumping applications and help avoid premature failures in the installation. They are effective for reducing failures in rod body, pins and couplings. A complete line of couplings including, subcouplings, spray metal and guided coupling, are available both for beam pumping and progressive cavity pumping systems.

Applications include deep wells, deviated wells, harsh environments, and exposure to high torque, as well as high and low temperatures. We offer low alloy and medium alloy steel polished rods with a surface finish that ensures a proper seal in the stuffing box. They are produced under API standards for lengths up to 36 ft and can be polished, chromed and metalized. Downloads File Language Size Download. Sucker Rods Technical Catalogue.

This manual will take Oxygen O2 gas detector for example to demonstrate, gas detector for other gases have similar specification, please refer to appendix for detailed parameters. Application BST-MG01O2 portable O2 gas detecting alarm is applied to the underground coal mine, petrochemical industry, municipal, environmental protection and other spaces where it need to detect the O2 gas concentration in the environment and provide a alarm function. When the O2 gas concentration in the environment is higher or lower than that of preset alarm point, this device will send out sound and light alarm to warn the user who wears it to take protective actions. This device is portable and can be also used as a fixed device.

DOI: Progressing cavity pump artificial lift method is very efficient in the production of oils with high viscosity and oils which carry a great amount of sand. The greater the number of applications of progressing cavity pumping method, the greater the necessity of specifying the best operational set point in order to optimize the oil production.
