API 7k oilfield hoses
API 7K is one of the standards for drilling and wellhead equipment formulated by the American Petroleum Institute, which involves oilfield hoses. API 7K oilfield hose is a high-pressure corrosion-resistant hose, which is often used in oil drilling, oilfield exploitation and other industries, and is mainly used to transport high-pressure oil, natural gas and other media.
Key features of API 7K Oilfield Hose include:
1. High pressure resistance: able to withstand the impact and pressure of high-pressure medium, safe and reliable;
2. Anti-corrosion: using special materials and processing technology, it has good anti-corrosion performance;
3. Wear resistance: it can withstand the erosion and friction of high-speed flowing medium, and has a long service life;
4. High temperature resistance: able to withstand work in high temperature environment, safe and reliable.
API 7K oilfield hoses are used in drilling, hydraulic fracturing, cement slurry pumping, oil and gas transportation and other fields. At the same time, API 7K also stipulates the standards and requirements for the production, inspection, installation and use of oilfield hoses to ensure the quality and safety performance of oilfield hoses. The API 7K standard requires oilfield hoses to undergo strict quality control and testing, including visual inspection, dimension measurement, test pressure, pulsation test, durability test, corrosion test, etc. Only oilfield hoses that pass the test and meet the standards can be sold and used at the factory.
According to the requirements of API 7K standard, oilfield hose is usually composed of many different materials, including inner layer, reinforcement layer and outer layer. The inner layer is usually made of oil-resistant and corrosion-resistant synthetic rubber or polyurethane; the reinforcement layer is composed of multiple high-strength steel wire braids or steel wire spirals to enhance the pressure resistance of the hose; the outer layer is usually made of polyurethane, polyester or synthetic rubber to protect the hose from external damage.
In a word, API 7K oil field hose is a special hose with high strength, high pressure resistance, corrosion resistance, wear resistance and high temperature resistance. Safe and stable production of important resources such as
