A wire braided hose consists of crossing and woven high tensile steel wires overlapping one another to reinforce the tube below. Wire braiding machines perform a complex task of winding the wire intricately around the tube, like dancers around a horizontal maypole. The overlapping nature of braided wire not only increases burst resistance to the tube but also allows flexibility between the braids. The crisscrossing braided wire has more tensile play than a spiral hose, resulting in tighter bend radius and overall flexibility.

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.

Focusing on the intelligent transformation and upgrading of coal mine hydraulic support manufacturing, we have carried out technical research, took multiple measures to solve the problem of "stuck neck", produced and developed differentiated mining braided/wound hoses, supporting the use of Litong Technology's mining U-shaped pin quick couplings , It can meet the requirements of hydraulic systems such as comprehensive coal mining units to transport coal oil, water-based hydraulic oil or water under extreme high pressure and harsh conditions without pressure, and improve work and production efficiency.

Characters: made of special rubber with good oil and weather resistance, reinforced with copper coated steel wire and black fabric appearance

Uses: Suitable for coal mine hydraulic supports, integrated coal mining unit hydraulic system to transport mineral oil, water-based hydraulic oil and water, and can be used at -40℃∽+100℃ (-40℉∽+212℉).

Hose structure: It is made of special rubber with good resistance to oil and weather, reinforced by copper-plated steel wire, and the appearance is black cloth pattern. The hose implements the MT/T98-2006 standard.
