brass coated hose wire

Used for high pressure rubber hose reinforcement;
Annual output reached 60000 tons;
Awarded ISO9001: 2008 certificate.........

       Hose wire is also called steel wire for hose reinforcement, brass-plated steel wire, rubber tube wire, or brass rubber tube wire.It is used as the reinforcement layer of the rubber hose.These high-pressure rubber hoses could sustain high pressure and high impact, and they can be used for machinery, aviation, ocean, oil drilling and some other special occasions. The hose reinforcement steel wire is carried out in line with GB/T 11182-2006 Standard, also can be manufactured according to DIN, ASTM, JIS and so on.Other specifications according to customers' requirements are also available.

         The surface of steel wire for hose reinforcement is plated a layer of uniform copper zinc alloy.The ratio of copper to zinc is 68±4%:32±4%.The weight of brass coating is heavier than 3.0g/kg. The steel wire has good line shape, the nature winding diameter is no less than 120mm, and the wire cutting warp(to the coil section) is no more than 50mm.The ellipticity of steel wire is not more than half of the diameter tolerance.The elongation of steel wire at breaking is not less than 2% ,which could be arranged by our customers.

          

The advantages of our products

First, the diameter of steel wire:The diameter tolerance that our company controlled can be ±0.005mm,which makes steel wire to be more uniform and stable, so as to improve the quality of our customers pruducts.

Second, The tensile strength of steel wire: Applying advanced equipment and exquisite technology, our company can produce the hose steel wire with tensile strength could be reached 2750Mpa and 3050Mpa.This technology is the first-class invention in domestic. Especially in the advantage of the strength tolerance, the tolerance of each steel wire by national standard is 300 Mpa,but the strength tolerance of steel wire produced by our company could be controlled within 200 Mpa,which makes our customers rubber hose to sustain higher pressure and stronger pulse impact.

Third, the advantage is fixed-length: The fixed-length of the steel wire that other manufacturers produced can not be consistent, this could lead  3-5% steel wire of each spool disable to use, while the fixed-length of all spools of steel wire that our company produced is consistent,this can enable our customers to use each spool entirely , thereby to reduce the cost of our customers products and increase the economic benefit of our customers.
