Pressure vessels contain a very large amount of energy, so when they explode, they cause unforeseen damage. used to pressure vessels, chemical processes as well as storing and transporting solvents. Below, Hong Chau Mechanical will highlight some common problems, the causes of the problem and some solutions.
1. Incidents related to pressure vessels
In the process of using pressure-bearing devices, high pressure fluid pipelines often have the following incidents: explosion, chemical burns, fluid leaks affecting respiratory ability (suffocation) , poisoning). These incidents have serious consequences on people and property if not handled properly.
2. Causes of pressure vessel incidents
Problems related to pressure vessels are often caused by improper design, operation, inspection, maintenance and repair. Specifically, such as wrong design, improper operation, over-working pressure, overheating, safety valve, unreasonable operating parameters, corrosion, cracking (welding seam, metal). basic), problems related to welding quality, erosion (abrasion) due to flow, material fatigue, material stress, wrong material selection or defective material, water depletion, internal errors. heating process, installation location, inappropriate safety distance, error during processing, manufacturing, inspection process, incomplete inspection, congestion, repair, replacement, capacity of maintenance and repair units.
3. Solution
♦ Strictly complying with the design and manufacturing requirements that the standard has prescribed.
♦ Eliminate equipment not manufactured according to standards, designed and manufactured according to reputable international standards.
♦ Operating the device at a pressure below the allowable pressure as well as installing protective devices (safety valves, pressures, relays, ...).
♦ Periodically checking and inspecting boilers, pressure vessels as well as safety equipment, accessories to detect elements of corrosion, leakage, cracking, breakage ... or other defects. Safety valves must be removed during inspection as well as periodically checked for their effects.
♦ Maintain records as well as inspection reports to monitor hazards to stop using the device before the risk of malfunction.
♦ When renovating, repairing must be done by reputable and licensed units about it. As well as complying with the repair regulations that the standard specifies.
♦ Provide knowledge about safety when working and operating these equipment as well as how to identify unsafe factors during the operation of equipment.
♦ Periodically provide training to businesses on pressure vessel operating procedures to avoid excessive operation, as well as provide them with adequate and appropriate guidance on safe pressure vessel safety activities.
The application of standards, standards and compliance with operating, inspection, testing and maintenance procedures to ensure that all Pressure cylinders are operated. It is extremely important and necessary to avoid accidents involving pressure vessels.
