Choosing a reliable supplier is essential for buying high-quality hydraulic hoses. Strongflex has 20 years of experience in the hydraulic hose industry, and has received many positive comments from customers, you can visit our factory at any time, and we are committed to bringing better service and support to our customers.
We use high-quality steel wire, after stranding and testing, and use advanced winding machines to produce the hydraulic pipes required by the department. Fully automatic parameter setting, precise production. Complies with international industry standards.
Pulse testing of hydraulic hoses is to test the durability of hydraulic hoses in actual use, and is also an important step in quality control, which can ensure the safety and durability of spiral hydraulic hoses in high-pressure and high-pulse applications.
Spiral hydraulic hose is a kind of high-pressure hydraulic hose. Its main feature is that the reinforcement layer is made of multiple layers of high-strength steel wire spirally wound, which has excellent pressure resistance and can maintain the reliability and efficiency of the hydraulic system under high pressure, high temperature and harsh environment. Specific applications include construction machinery, agricultural machinery and equipment, automobile manufacturing, aircraft and ships, etc.
Spiral hydraulic hose has excellent resistance to high pressure, pulse and abrasion, and is the strongest type of hydraulic hose. Our heavy-duty spiral hydraulic hose is wound with four or six layers of high-strength steel wire. The spiral design is easy to install and flexible, and can adapt to various hose sizes while maintaining a secure fit.
Wire spiral hose and wire braided hose are two common hydraulic hoses. They are both composed of an inner rubber layer, reinforcement layer and an outer rubber layer, but their reinforcement layer structures are different. The reinforcement layer of the wire spiral hose is made of steel wires wound, while the reinforcement layer of the wire braided hose is made of steel wires interwoven and woven.
Wire spiral hydraulic hoses usually have high tensile strength and pressure resistance, and are suitable for high and ultra-high pressure working environments. Wire braided hydraulic hoses also have good corrosion resistance and wear resistance, and can be used in humid and corrosive environments.
The main purpose of the spiral hydraulic hose is to be used in high-pressure, high-pulse hydraulic systems, and is widely used in the following fields:
Engineering machinery and equipment (such as excavators, loaders, bulldozers)
➤ Used for the connection of high-pressure oil circuits in hydraulic transmission systems, and withstand severe impact and vibration.
Agricultural machinery (such as harvesters, seeders)
➤ Suitable for high-frequency operation and high-pressure load hydraulic systems to ensure operating efficiency.
Mining and quarrying machinery
➤ Can withstand high-pressure transmission in extremely harsh environments, such as mining machines and drilling rig hydraulic systems.
Industrial hydraulic equipment
➤ Suitable for hydraulic circuits of industrial automation equipment, such as pressure forming machines, hydraulic lifting platforms, etc.
Oil and gas industry
➤ Used for high-pressure hydraulic control of oilfield equipment, with strong corrosion resistance and explosion resistance.
