Steel wire braided steam hose EPDM rubber material
As a core component in the field of industrial fluid transmission, the customized production capacity of DN25 to DN50 specifications for steel wire braided heat-resistant steam hoses directly affects the reliability and safety of equipment operation. This type of product achieves stable operation in high temperature and high pressure environments by optimizing material combinations and structural design, and is widely used in scenarios such as boiler systems, steam turbines, and injection molding machinery.
Technical parameters and structural characteristics
The steel wire braided steam hose with specifications from DN25 to DN50 has an inner diameter range of 25mm to 50mm, and the outer diameter is dynamically adjusted according to the number of braiding layers and working pressure. Taking the DN25 specification as an example, the outer diameter of a single-layer steel wire braided rubber hose is about 37mm, while the outer diameter of a double-layer braided structure can reach 40mm. The core structure of this type of hose consists of four layers: the inner rubber layer is made of ethylene propylene diene monomer (EPDM) or special synthetic rubber, which has excellent steam aging resistance; The reinforcement layer of the intermediate layer is formed by copper plated high-strength steel wire weaving or winding process to form a skeleton. The single-layer weaving can withstand a working pressure of 1.0MPa, while the double-layer structure can increase it to 2.0MPa; The outer rubber layer is made of weather resistant synthetic rubber to ensure physical stability within the temperature range of -30 ℃ to+210 ℃.
The core advantage of customized production
Customized length services have broken through the traditional 20 meter fixed length limit and can achieve flexible production from 0.3 meters to hundreds of meters. This capability stems from modular manufacturing processes: the inner rubber layer is formed through extrusion technology, the steel wire weaving layer is precisely controlled in density through CNC weaving machines, and the outer rubber layer is tightly combined with the reinforcement layer through vulcanization technology. For example, in the hot runner system of an injection molding machine, DN32 specification rubber hoses need to be customized to a length of 1.5 meters to match the equipment layout; In the renovation of ship steam pipelines, DN50 specification rubber hoses need to be produced in sections of 50 meters to meet continuous transmission requirements. Customized production is also reflected in the joint configuration, and flange, quick plug or threaded connection methods can be provided according to customer requirements.
Application scenarios and performance validation
In the field of steam cleaners, DN25 rubber hoses need to withstand intermittent impacts of saturated steam at 184 ℃, and their burst pressure needs to reach more than 10 times the working pressure. According to test data from a certain injection molding machine manufacturer, the DN40 rubber hose with a double-layer steel wire weaving structure did not show any cracking of the inner rubber layer or rusting of the steel wire after continuous operation for 2000 hours under a working pressure of 1.6 MPa. For DN50 specification rubber hoses, continuous transmission of 204 ℃ high-temperature steam is required in ship steam pipelines. The minimum bending radius is designed to be 10 times the pipe diameter to ensure flexibility in complex pipeline layouts.
Quality Control and Standard Compliance
The production process strictly follows the HG/T3036-99 standard, and each batch of products must undergo triple testing: the inner rubber layer must pass a 168 hour steam aging test, the steel wire braided layer must undergo a tensile test to ensure a fracture strength of not less than 1500N/mm ², and the finished rubber hose must pass a water pressure burst test at 4 times the working pressure. A sampling report from a third-party testing agency shows that a batch of DN32 rubber hoses remained leak free for 30 minutes under a pressure of 2.4 MPa, and the burst pressure reached 6.3 MPa, far exceeding the standard requirements.
