In the vast ocean transportation industry, the performance of ship fuel transfer hoses, as key components connecting fuel supply and ship power systems, directly affects the safe operation and economic benefits of ships. In recent years, with the development of the shipbuilding industry and the increasing emphasis on fuel transportation safety, high-performance, corrosion-resistant, leak proof, safe and durable hoses have become an urgent demand in the market. The LT1203 high-performance marine fuel delivery hose is an outstanding product born to meet this demand. This article will delve into the material composition and performance characteristics of LT1203 hose, its corrosion resistance and leak prevention mechanisms, as well as its application and advantages in the shipbuilding industry, in depth.

 

1、 Material composition and performance characteristics of LT1203 hose

The LT1203 high-performance ship fuel delivery hose is carefully developed and produced by Luohe Litong Hydraulic Technology Co., Ltd. It adopts a series of advanced materials and technologies to ensure its excellent performance in complex and changing marine environments.

 

Inner rubber layer: Made of black NBR (nitrile rubber) synthetic rubber, this material has excellent oil resistance, solvent resistance, and corrosion resistance, which can effectively resist the corrosion of chemical substances in the fuel on the inner wall of the hose, ensuring the purity and safety of the fuel.

Enhancement layer: composed of high tension synthetic fiber winding and high flexibility spiral steel wire winding, this design not only enhances the pressure bearing capacity of the hose, but also improves its tensile and torsional resistance, ensuring the stability and durability of the hose under extreme conditions.

Outer rubber layer: black NBR and PVC fire-resistant and flame-retardant hybrid rubber is used. This outer layer not only has excellent wear resistance and anti-aging performance, but also can effectively prevent fire spread under unexpected circumstances such as fire, further improving the safety of the hose.

Temperature range: The LT1203 hose has a wide working temperature range and can operate normally in environments ranging from -20 ° C to 100 ° C, meeting the fuel delivery needs of ships under different climatic conditions.

Working pressure and burst pressure: The working pressure of this hose reaches 75psi, with a minimum burst pressure of 188psi, ensuring stability and safety during fuel delivery.

2、 Corrosion resistance and leakage prevention mechanism

In marine environments, fuel delivery hoses face multiple challenges such as salt spray corrosion, seawater erosion, and corrosion from chemical substances in fuel. The LT1203 hose effectively addresses these issues through a series of innovative designs, ensuring its corrosion resistance and leak prevention performance.

 

Corrosion resistant material: As mentioned earlier, the inner rubber layer of LT1203 hose is made of NBR synthetic rubber, which has extremely strong corrosion resistance and can effectively resist the erosion of various chemicals in fuel, thereby extending the service life of the hose.

Enhancement layer design: The winding design of high tension synthetic fibers and high flexibility spiral steel wires not only enhances the pressure bearing capacity of the hose, but also improves its overall structural stability. This design enables the hose to quickly return to its original shape when subjected to external pressure or impact, effectively preventing leakage caused by deformation.

Sealing performance: The connection method of LT1203 hose adopts a crimping type, which can ensure a tight fit between the hose and the joint, effectively preventing fuel leakage during transportation. At the same time, there is a special sealing layer between the inner and outer layers of the hose, further improving its leak prevention performance.

Wear resistance and aging resistance: NBR and PVC mixed rubber is used as the outer rubber layer. This material not only has excellent wear resistance, but also can effectively resist the erosion of the outer layer of the hose caused by environmental factors such as ultraviolet light and oxidation, thus extending the service life of the hose and reducing the risk of leakage.

3、 Application and advantages of LT1203 hose in the shipbuilding industry

The LT1203 high-performance marine fuel delivery hose has been widely used in the shipbuilding industry due to its excellent performance and reliability. Here are several main application scenarios and advantages of it in the shipbuilding industry:

 

Fuel delivery system: As a key component of the ship's fuel delivery system, the LT1203 hose ensures efficient and safe delivery of fuel from the storage tank to the engine. Its corrosion resistance and leak prevention performance effectively reduce the risk of safety accidents caused by fuel leaks.

Ship repair and maintenance: During the process of ship repair and maintenance, it is often necessary to replace aging fuel delivery hoses. The LT1203 hose, with its long lifespan and corrosion resistance, can significantly reduce replacement frequency, thereby lowering maintenance costs and time.

New ship construction: During the new ship construction process, the LT1203 hose serves as a standard configuration for the fuel delivery system, which can enhance the overall performance and safety of the new ship. Its excellent temperature and pressure resistance ensure the stable operation of the new ship under various weather conditions.

Environmental Protection and Energy Efficiency: The LT1203 hose is made of environmentally friendly materials and can effectively prevent fuel leakage during use, thereby reducing pollution to the marine environment. At the same time, its efficient fuel delivery capacity also helps to improve the fuel utilization efficiency of ships and achieve energy-saving and emission reduction goals.

In summary, the LT1203 high-performance ship fuel delivery hose has become a leader in ship fuel delivery systems due to its excellent material composition, corrosion resistance and leak prevention mechanism, as well as its wide application and advantages in the shipbuilding industry. With the continuous development of the ocean transportation industry and the increasing demand for fuel transportation safety, LT1203 hoses will continue to play an important role in providing strong guarantees for the safe operation and economic benefits of ships.
