API 17K Jumper Hose: A Core Flexible Connection Solution for Offshore Oil and Gas Engineering

I. Main Purposes

The API 17K jumper hose is a crucial flexible connection component in the offshore oil and gas gathering and transportation system. It is mainly applied to the fluid transportation between offshore platforms, trestles, and subsea production systems, undertaking the efficient transmission of media such as crude oil, natural gas, mud, and chemical agents. Its core scenarios include:

Trestle Jumping between Platforms: In offshore oil and gas field projects such as Wenchang 13 - 2 and Panyu 11 - 12, it is used to connect the fluid channels between fixed platforms and trestles.

Support for Deep - sea Equipment: It provides high - pressure fire - resistant fluid transportation pipelines for ultra - deep - water drilling platforms such as "Offshore Oil 981" and "Blue Whale I".

Operation in Extreme Environments: Under harsh working conditions such as high temperature, high pressure, high salt - fog, and hydrogen sulfide corrosion, it replaces traditional rigid pipelines to achieve safe transportation.

II. Structural Design

The API 17K jumper hose adopts a multi - layer composite structure, achieving adaptability to extreme working conditions through the collaborative design of "material - process - structure", mainly including:

Inner Rubber Layer: A special rubber formula resistant to oil and chemical corrosion is used to ensure zero penetration of the medium.

Reinforcement Layer: Woven or wound from high - strength steel wires, it can withstand a maximum working pressure of 30MPa, meeting the requirements of the API 17K standard for pressure resistance and tensile resistance.

Outer Rubber Layer: Anti - aging, anti - ultraviolet, and fire - retardant additives are added to adapt to the erosion of ocean salt - fog and wind - waves.

Joint Connection: The integral vulcanization embedding process is used to achieve a seamless combination of the hose and the metal joint, avoiding the risk of leakage.

III. Core Advantages

Full - working - condition Adaptability

The product has passed API 17K certification and certifications from international classification societies such as CCS and DNV. It can operate stably in a temperature range of - 40°C to 120°C and a chemical environment with a pH value of 2 - 13. During Typhoon "Capricorn" (Category 17) in 2024 and Typhoon "Hagasa" in 2025, the hoses serving in the Wenchang Oilfield remained structurally intact under the once - in - a - century wind - wave load.

Independent and Controllable Technology

It breaks the monopoly of international brands and realizes the localization of the entire chain of "underlying R & D - certification - application". As the first domestic enterprise to obtain API 17K certification, Yuelong Technology's 27 invention patent technologies, such as the ultra - high - pressure tube body pressure - bearing design and the integral vulcanization joint process, have enabled the product performance to reach the international leading level.

Long Life and Low Maintenance

By using the full - working - condition adaptable material composite technology, the designed service life of the product reaches 20 years, a 50% increase compared with traditional hoses. The integrated service capability covers the entire cycle of design, installation, and maintenance, significantly reducing offshore operation and maintenance costs.

IV. Market Application and Industry Value

The API 17K jumper hose has been widely equipped for international energy giants such as ExxonMobil and Schlumberger. In 2025, overseas sales revenue accounted for 45.44%. Its breakthrough in localization not only enhances the safety of China's offshore oil and gas equipment industry chain but also promotes the upgrade of industry technical specifications by participating in the formulation of 10 national standards such as GB/T 46167 - 2025, providing key guarantees for deep - sea resource development.
