  17K Jumper Hose Special Topic

  ‌Technical Standards‌：API 17K certification is designed for deep-sea high-pressure environments, requiring hoses to have durability under extreme pressure (600 MPa) and corrosive conditions. Letone Technology is one of the few domestic companies to hold triple certifications: API 7K, 16C, and 17K.

  ‌Product Advantages‌：It features high pressure, lightweight, and long service life, and its corrosion resistance is superior to traditional steel hoses, making it a viable alternative to steel hoses for deep-sea oil and gas transportation.

  Heat Exchangers And Gaskets

  Plate heat exchangers offer advantages such as high heat exchange efficiency, small footprint, simple manufacturing, and easy maintenance. They are suitable for applications in HVAC systems, including district heating, domestic hot water, ice storage, and swimming pool temperature control; in the petrochemical industry, they are used for cooling acid, alkali, and salt solutions, and for process media heating/cooling systems. They are also found in power, steel, metallurgy, food, paper, shipbuilding, pharmaceutical, textile, and automotive industries—wherever heat exchange is required, plate heat exchangers have market applications. As part of our plate heat exchanger gasket manufacturing process, our team adheres to precise and rigorous procedures at every stage.
