| High Light | Super Artery Wire Spiral Hose ，Construction Machinery Wire Spiral Hose ，Super Artery spiral hydraulic hose | ||
A spiral wound hose consists of two or more sets of helically wrapped high-tensile wire that exhibits exemplary strength, making the hose very strong but also very rigid. The resistance to pressure spikes is exceptionally high, especially compared to a braided hose. However, the bend radius suffers, and spiral wound hose is highly resistant to bending. This effect is especially pronounced with 4- or 6-wire hoses, which are required from many large diameter, high-pressure applications.

Note style
Low bend:The average minimum bending radius of the entire series of hoses is 34% lower than the ISO18752 Class C standard (Note: The Class C standard refers to the compact category in the ISO18752 standard), which is easy to install and save equipment space；
High pressure:All pressures meet/exceed ISO18752 AC/BC/CC/DC standards；
Life:Powerful pulse performance, the pulse times of the entire series of hoses are more than 1 million times, which greatly extends the service life of the hose.

Based on EN853: 2015, the outer layer of the Super Hercules low bending hose series is reciprocated at a frequency of 1.25HZ under 25N gravity according to the method specified in the GB/T 12721-2007/ ISO6945: 1991 inspection standard. In the abrasion test, the quality loss of the outer layer material under 2000 cycles is compared, and the outer layer of the Super Hercules low-bending hose is divided into the following three types:
