32mm four-layer steel wire wrapped high-pressure hose
in high-pressure hydraulic systems, the 32mm inner diameter four-layer steel wire wrapped high-pressure hose is a key power transmission component, and its performance directly affects the reliability and safety of equipment operation. As an industry leader, LETONE Hydraulic Technology provides industrial users with truly trustworthy high-pressure hose solutions with innovative technology and strict quality standards.
The hose adopts a special synthetic rubber inner layer + four-layer steel wire reinforcement + wear-resistant outer layer structural design to ensure reliability under extreme working conditions.
I. Analysis of the pressure resistance performance of four-layer steel wire winding hose
1. Technical guarantee for 42MPa high working pressure
Reinforcement layer structure: 4 layers of 0.3mm ultra-high strength steel wire (tensile strength ≥2200MPa), with 54°~56° optimized winding angle
Interlayer bonding: RFL adhesive treatment, peel strength ≥12N/mm, to prevent delamination
Explosion safety factor: The measured explosion pressure reaches 175180MPa, far exceeding the industry standard
II. Five reasons to choose LETONE hydraulic technology
1. Military-grade material technology
Inner rubber layer: hydrogenated nitrile rubber (HNBR), oil resistance is 40% higher than ordinary NBR
Reinforced steel wire: Baosteel special steel wire, single wire tensile strength reaches 2200MPa
Outer rubber layer: CR/CSM blended formula, wear resistance index 180mm³ (ordinary products are about 120mm³)
2. German manufacturing process
German DESMA fully automatic braiding equipment (accuracy ±0.01mm)
Swiss TROESTER continuous vulcanization production line (temperature control ±1℃)
100% online Xray detection to eliminate quality defects
3. Quality assurance system beyond the industry
500,000 pulse tests (industry standard 300,000 times)
55℃ low temperature bending test (standard requirement 40℃)
Triple pressure test (working pressure, bursting pressure, pulse pressure)
4. Professional customization capabilities
Ultra-high pressure type: up to 70MPa (6 layers of steel wire reinforcement)
Extra-long type: up to 50 meters for a single root (standard 20 meters)
Special joints: provide flanges, 37° flaring, quick change and other connection methods
5. Global success stories
Engineering machinery: supporting Sany Heavy Industry and Xugong, with a service life of 8,000 hours
Energy field: CNOOC deep-sea platform application (water depth 1,500 meters)
Mining equipment: Continuously used for 3 years in Shenhua Group underground without failure
III. Typical application scenarios
1. Main hydraulic system of shield machine: withstand high-frequency pressure fluctuations
2. Metallurgical equipment: high temperature resistant hydraulic oil transmission
3. Ship deck machinery: anti-seawater corrosion design
4. Oil drilling equipment: explosion-proof and anti-static structure
