What is the maintenance of large diameter high pressure hose?
Warehouses where high-pressure hoses are stored should be kept clean and ventilated. The relative temperature is below 80%, and the temperature in the warehouse should be kept between -15 and 40 degrees to avoid direct sunlight and wet rain and snow. So how is the maintenance of large-diameter high-pressure hoses?
What is the maintenance of large diameter high pressure hose?
1. When storing high-pressure hoses, they should be stored separately according to different varieties and specifications. Do not mix or stack, and mark for access.
2. High pressure hoses should be stored as much as possible. Hoses smaller than 76 mm can be dyed (but the inner diameter of the rolling shall not be less than 15 times the inner diameter of the hose).
3. In order to prevent the pipes in the high-quality pipes from being compressed and deformed, the stacking height should not exceed 1.5m. Generally speaking, the hoses need to be "inverted" frequently during the storage process.
4. When storing high-pressure hoses, do not contact acids, alkalis, oils, organic solvents or other corrosive liquids and gases; and keep them away from heat sources for 1m.
5. When storing the hose, it is strictly forbidden to use heavy objects to prevent external extrusion and damage.
6. The general storage time of the high-pressure hose should not exceed two years. It should be anticipated to prevent long-term quality issues.
7. Due to the complexity, structural diversity and use conditions of high-pressure hoses, the service life of the hose depends not only on quality, but also on use and maintenance. Therefore, even if a product is of extremely high quality, if it is not used and maintained properly, its quality and service life will be severely affected.
What is the future development trend of large-diameter high-pressure hoses?
1. The use of high pressure hose should be mainly in the petroleum industry and coal industry. The focus of CNOOC's development strategy in the 21st century is to develop offshore and shallow oil fields. Therefore, in addition to drilling and vibrating tubing, the petroleum industry also requires the use of shallow seawater pipelines to transport pipelines. my country has produced the necessary shallow sea water pipelines, but floating or semi-floating oil pipelines and deep sea water pipelines still rely on imports.
2. With the implementation of my country's offshore oil development strategy, the requirements of offshore oil exploitation on the performance of tubing will continue to increase. In recent years, the pressure of some coal mine hydraulic supports has been improved. Some steel wire braided pipes cannot meet their performance requirements and require the oil pipe to be wrapped with steel wire. In addition, in the process of coal mining, in order to prevent coal dust pollution and improve production safety, various coal mineral oil pipes for water injection and grouting of coal seams in coal mines, such as coal seals, shrink oil pipes, etc. Wait for the job. According to reports, the manufacturer already produces in China and is trying to substitute similar imported products through a dozen coal mines.
