The selection of metal hoses includes the type of joint (mainly flange connection, threaded connection, quick connector connection) and the size and length of the metal hose. The specific five elements are as follows: 
1. The nominal diameter of the size hose tells us the type of joint to be selected (mainly flange connection, threaded connection, quick connector connection) and the size and length of the metal hose. 
2. The pressure needs to be based on the actual working pressure of the hose, and then the nominal diameter and pressure gauge of the corrugated metal hose need to be checked before deciding whether to use a stainless steel mesh type metal hose. 
The chemical properties of the medium conveyed in the medium hose are determined by the corrosion resistance of the hose material, which determines the material of each component of the hose. 
4. The working temperature and range of the medium inside the temperature hose; The ambient temperature during the operation of the hose. 
5. Calculate the length of various motion states of the hose, as well as factors such as the number of bends and bending radius of the hose. Select the correct length of the hose and install it correctly.

EPDM rubber, chlorosulfonated polyethylene, chloroether rubber, hydrogenated nitrile rubber, etc. are gradually being applied to high-pressure hose manufacturers' products.Used for manufacturing high-performance, high value-added high-pressure hose products.Non metallic reinforcement materials include nylon and polycarbonate fibers. With the development of the textile industry, high-performance materials such as aramid fibers are gradually being used in high-pressure rubber hoses.Metal materials include copper plated steel wire with a circular cross-section and galvanized steel wire as the skeleton layer material. With the advancement of technology, flat steel wire (copper plated steel wire with an elliptical cross-section) will be used in high-pressure rubber hoses.

The large-diameter mud suction and discharge hose is a key component of modern engineering, which efficiently sucks and discharges mud with a super large diameter to adapt to complex working conditions. Made of high-strength and wear-resistant synthetic rubber, precision processed and vulcanized to ensure flexibility and durability. Smooth inner wall reduces resistance and improves efficiency. Equipped with advanced connectors and sealing system, the connection is firm and leak proof. Suitable for deep well drilling, tunnel construction, water conservancy construction, port dredging, etc. Corrosion resistance, anti-aging, long-term stable use in harsh environments. The unique structural design maintains good sealing and conveying capabilities even after bending and twisting, ensuring the smooth progress of the project. It is an indispensable and important tool in the field of engineering.

With the acceleration of urbanization, the municipal pipelines in Chang'an District are facing unprecedented pressure. The increasingly prominent problems of sewage discharge and rainwater accumulation have brought many inconveniences to citizens' lives. To address these issues, the municipal departments of Chang'an District work closely with professional pipeline dredging companies to regularly clean and dredge pipelines. They use advanced dredging equipment and technology to efficiently and safely complete dredging work, ensuring smooth and unobstructed pipelines.

Large diameter flange wear-resistant mud hose is a key component in industry, suitable for transporting high wear mud. Adopting wear-resistant synthetic rubber lining, it is resistant to erosion, corrosion, and aging. Large diameter and high-strength flange connection improve installation efficiency and sealing, and prevent leakage. Strong pressure bearing capacity, reinforced with outer fibers or steel wires, resistant to tearing and bursting. Widely used in industries such as petroleum, chemical, mining, and water conservancy to process high wear mud, demonstrating professional value and potential.

Chemical hoses are used to handle different types of acid, inorganic acid, alkali, and inorganic mineral aqueous solutions during production and transfer operations. These chemical hoses have precise accuracy, weather resistance, and long service life. There are multiple sizes and styles to choose from, suitable for the transfer of chemicals, alcohol, petroleum, acid, fertilizers, and paint in industrial plants.

Common applications include: transferring acids, chemicals, solvents, and petroleum products; Loading and unloading, pumping, suction or gravity flow discharge, inhalation and discharge of chemicals and solvent chemicals, alcohol, acid and petroleum, in plant transfer, spraying of insecticides, fertilizers and paints. It can handle 98% of existing chemicals.
