Chemical Injector – flange connection

Description

Disassembly of a Chemical Injector under pressure is a part of the chemical injection system. There are three kinds of Chemical injector: flange connection, welded link, and pressurized disassembly. They can all inject reagents into the pipeline. However, the difference is that the pressure disassembly chemical syringe can be disassembled and installed when the pipeline works normally. Because a valve is installed at its connection. Therefore, when the pipeline is still under pressure, the valve can be closed for disassembly. In this way, the user can carry out the disassembly operation while ensuring the normal operation of the pipeline. Therefore, it can save the production time of the factory to the greatest extent.

Chemical Injector Access Fitting Body

In general, compared with other chemical syringes, the pressure disassembly Chemical Injector has many advantages. Firstly, compared with the flange-connected chemical syringe, it has higher cost performance. However, the chemical syringe disassembled under pressure can only be connected to the pipeline by welding. Therefore, this product cannot be used on the pipeline with flange. In addition, compared with the other two chemical syringes, it has the feature of disassembly under pressure. So in the case of tight production time in the factory, this product is the best choice.

Characteristic:

1. Firstly, the installation and disassembly will not delay the factory operation. So it can save time.
2. Secondly, convenient disassembly and easy operation.
3. At last, compared with flange connected chemical syringe, it has a higher cost performance. So more practical.

Background:

The development of offshore oil and gas fields is inseparable from chemical agents. Which are mainly used to add to the production fluid, seawater, and other media, to improve the treatment efficiency of relevant treatment equipment, and also protect production equipment and wellhead pipelines. And also extend the service life of production equipment and pipelines. So as a part of the chemical injection system, the chemical injection parts stretch into the pipeline and are washed and corroded by the production fluid.

With the extension of service time, the injection parts will be damaged to varying degrees, affecting the injection effect of chemical agents. And then the replacement cost of injection parts is relatively high with the continuous development of science and technology. Some chemical injection parts developed successfully can also solve the problem of the high replacement cost of injection parts. However, due to high manufacturing costs and diverse design structures. So it is challenging to achieve standardization, serialization, and mass production.

Therefore, in the existing technology, there is an urgent need for a technical scheme that can be used as standard parts for production and manufacturing, realize standardization and serialization according to the pressure level in the production and manufacturing process, solve the problem of maintenance and replacement of chemical injection parts, and contribute to the optimization of the production process.
