The Steam Hose, also known as the steam hose in English, is a flexible pipe specially designed for the safe transmission of steam and hot water. It plays a key role in industrial fields and some civilian scenarios.
Inner tube: The inner tube is the part that comes into direct contact with steam, and the selection of its material is of vital importance. The common inner tube materials are ethylene propylene diene monomer (EPDM) Rubber or Chlorobutyl Rubber.
Reinforcing layer: To enable the steam hose to withstand the high pressure brought by high-temperature steam, the reinforcing layer adopts a structure combining multiple layers of high-strength synthetic fibers with a steel wire spiral skeleton.
Outer coating: The outer coating is generally made of rubber materials with special properties. Its color is commonly black or red, and the outer surface has a specific texture. This layer is also mostly made of EPDM material, which has excellent weather resistance, ozone resistance and wear resistance.
In the petrochemical industry: During the petroleum refining process, steam is used in the distillation and catalytic cracking of crude oil and other technological links. Steam hoses are responsible for transporting high-temperature and high-pressure steam to various reaction devices and equipment. Meanwhile, in the production process of chemical products, such as synthetic rubber and plastic, steam is also an important energy carrier and reaction medium. Steam hoses play an indispensable role in steam transmission in these complex chemical production processes.
In the power industry: Steam is the key power source that drives the turbine to rotate and generate electricity in thermal power stations. Steam hoses are used to connect boilers, steam turbines and other equipment to ensure that steam can be transmitted efficiently and stably.
Q: How do I choose the right hose size?
A: Select based on steam flow requirements and pressure ratings. For example, the ST-1W-20 (1-1/4” ID) is ideal for moderate flow at 10 bar (150 psi), while the ST-2W-24 (1-1/2” ID) handles higher flow at 18 bar (270 psi).
Q: Can these hoses be used for superheated steam?
A: While primarily designed for saturated steam, the ST-2W series can tolerate short-term exposure to superheated steam. However, prolonged use may reduce lifespan. Always consult the technical specifications for temperature limits.
