1. Classification of high-pressure oil drilling hoses
High-pressure oil drilling hoses mainly include steel wire wound reinforced hydraulic hoses, steel wire braided reinforced hydraulic hoses and steel wire wound reinforced rubber hoses. Among them, steel wire wound reinforced hydraulic hose is the most widely used high-pressure oil drilling hose. Its structure mainly consists of an inner rubber layer, a middle rubber layer, an outer rubber layer and a steel wire reinforcement layer. The inner rubber layer has the characteristics of wear resistance, aging resistance, ozone resistance and chemical corrosion resistance. The middle rubber layer has excellent resilience, air tightness and tear resistance. The outer rubber layer has the characteristics of protecting the steel wire and resisting external force.
2. Applications of high-pressure oil drilling hoses
High-pressure oil drilling hoses are mainly used to connect high-pressure oil drilling equipment and tools, transmit power and pressure during the drilling process, and at the same time protect the safety of equipment and personnel. In addition, high-pressure oil drilling hoses can also be used to transport flammable, explosive, toxic media such as oil and natural gas, as well as other occasions that require the use of high-pressure fluid media.
3. Implementation standards for high-pressure oil drilling hoses
The production and inspection standards of
high-pressure oil drilling hoses are mainly in accordance with standards such as GB/T 15908-2009 "Rubber Hose and Assemblies for Drilling Fluids" and API Spec 11L-14 "Specification for Rubber Hoses and Assemblies for Drilling." Among them, the GB/T 15908-2009 standard specifies the structure, performance requirements, test methods, inspection rules, marking, packaging, transportation and storage requirements for high-pressure oil drilling hoses, while the API Spec 11L-14 standard mainly targets high-pressure oil drilling hoses. The size, pressure resistance, burst pressure, tensile strength and other physical properties of oil drilling hoses are stipulated.
4. Technical parameters of high-pressure oil drilling hoses
The technical parameters of
high-pressure oil drilling hoses mainly include working pressure, bursting pressure, pressure resistance time, bursting time, minimum bending radius, minimum compression rate, etc. Among them, the working pressure refers to the maximum pressure that the hose can withstand under normal working conditions, the burst pressure refers to the maximum pressure that the hose can withstand under test conditions, and the pressure-resistant time refers to the time that the hose remains leak-free under the specified pressure. The bursting time refers to the time when the hose bursts under test conditions, the minimum bending radius refers to the minimum radius that the hose can bend in the free state, and the minimum compression ratio refers to the minimum compression ratio that the hose can achieve in the compressed state.
5. Precautions for high-pressure oil drilling hoses
When using high-pressure oil drilling hoses, you need to pay attention to the following points:
1. Before use, the appearance quality of the hose should be checked to ensure that it has no damage, cracks, bubbles and other defects.
2. During use, the hose should be protected from severe bending, twisting, scratching and other external forces to avoid damage or rupture of the hose.
3. When connecting hoses, appropriate joints and correct connection methods should be used to ensure a firm and reliable connection and avoid leakage or falling off.
4. During use, the pressure, temperature and other parameters of the hose should be checked regularly to discover and deal with possible problems in a timely manner.
5. During storage and transportation, avoid exposing the hose to sunlight or humid environment for a long time to avoid affecting its service life and quality. At the same time, packaging and transportation should be carried out in accordance with relevant regulations to avoid problems such as damage or deformation during transportation.
