Metal Material:SS304 Stainless Steel,Other material could be customized
Outer material: Asbestos
Advantages of metal hoses but asbestos
1. Sturdy and durable,precision welding ensures tight connection, will not break or leak oil.
2. High quality hose wall,thickened wall hose,pressure-resistant and explosion-proof,optional length,soft hose body,strong tensile performance.
3. It has the characteristics of high pressure resistance,explosion-proof and good flexibility,and it can be bent at will.
application
1. Steel metallurgy industry: stainless steel metal hose is gradually transitioning from product performance competition to performance-price competition, and the product structure is basically set.
2. Petrochemical industry: The development of new products in this field is far from meeting the market demand, at present, the hose in some occasions has been replaced by other products, such as the non-metallic pipe in the dock pipeline market.
3. Railway locomotive industry: Due to the Ministry of Railways data on the use of composite hose form of stereotyped provisions, product structure in recent years will not change very much, the current performance is mainly price and service competition. However, in the long run, due to the complex working conditions and the uncertainty of composite hose damage, from the development of the hose industry abroad, it is inevitable to be replaced by stainless steel metal hose
4. Shipping industry: In addition to the need for classification society testing, there is no special product technical performance requirements, but its market demand is also very huge. For example, if the inland river uses a floating wharf, stainless steel metal hoses must be used to compensate from the valve chamber to the oil delivery arm, otherwise huge interface stress will be formed, causing serious damage to the loading and unloading ship pipelines and oil delivery arm
5. Water supply and drainage, air conditioning industry: due to the advantages of high reliability, high temperature resistance, and large compensation amount, stainless steel metal hose has been more and more applied in water supply and drainage and air conditioning water systems in recent years.
6. Wire protection tube for armored optical cable, optical ruler, optical measuring instrument, medical instrument, machine equipment: Asbestos rubber pipes are made of alkali-free glass fiber braided bushings and covered with thick iron oxide red silica gel, which can withstand high voltage, block molten iron splash, and not be damaged by high
7. temperature and flame, which makes them suitable for protecting hoses, cables and pipe2 in harsh environments
High temperature areas, heating area cables, fluid pipelines, rolling mill cables, tubing, sawing perimeter cables, generator sets, electrical voltage equipment, large buildings, hydraulic systems, automotive wiring harnesses and exhaust pipes in other industries such as steel, smelting, shipbuilding and chemical industry: Asbestos rubber tubes can be continuously exposed to high temperatures of 260 degrees without damage, can withstand 15-20 minutes at temperatures of up to 1090 degrees, and can withstand 15-30 seconds at temperatures of 1650 degrees.
