Rubber hose:
Rubber hose is a steel wire braided hose. The hose is composed of an inner rubber layer, a steel wire braided layer and an outer rubber layer. It is suitable for conveying hydraulic fluids, such as alcohol, fuel oil, lubricating oil, emulsion and so on.
Appearance:
Distinguished from hard pipes, the biggest feature of (rubber) hoses is bendability.
Hose designs vary widely according to operating conditions and performance requirements. Common parameters include size, pressure, weight, length, bend, chemical durability, etc.
The application field of industrial hose covers various industrial manufacturing and circulation fields, and is widely used in petroleum, chemical, shipbuilding, dock, tanker, agriculture, food, beverage, medicine and other industries, as well as hot and cold water, steam, ventilation, cooling, fire protection and other industries. , Hydraulic, media such as gas, water, fog, mud, sand, iron, etc.
Industrial-grade rubber hoses, whether the medium is water, gas, oil, chemicals or others, usually consist of an inner rubber, an outer rubber and an intermediate layer. The middle layer is usually mostly braided, which strengthens the strength of the hose.
Industrial hose with steel wire
In addition to that, there are common embedded steel wires between the inner and outer rubbers, which are
suitable for vacuum negative pressure operations.
Industrial hose with conductive wire
There are also conductive wires, which are suitable for working environments where sparks are prohibited, such as fuel oil, etc.
Classification:
In order to adapt physical and chemical conditions of operations in various industries, industrial hoses usually have very strict implementation standards on chemical raw materials and production methods of internal and external colloids. According to working conditions, they are classified commonly as below:
Cooling water insulation hose
Water transmission hose: used in irrigation, horticulture, construction, fire protection, equipment and tanker cleaning, agricultural fertilizers, manure, industrial sewage drainage, etc. The inner rubber material is mostly PVC and EPDM.
High pressure steam hose
Hot water steam hoses: It is used for cooling water of refrigeration equipment, hot and cold water of engine, food processing, especially hot water and saturated steam in dairies. The inner rubber material is mostly EPDM.
potable water supply hose
Beverage food hose. For non-fat such as milk, carbonated, orange juice, beer, animal and vegetable oils, drinking water and so on. The inner rubber material is mostly NR or synthetic rubber. Usually need to have food grade FDA, DVGWA grade, KTW or CE and other standard qualification certification..
Heavy duty air hose
air hose: Used in compressors, pneumatics, mining, construction, etc. The inner rubber materials are mostly NBR, PVC composite, PU and SBR. Usually there are strict requirements on the applicable pressure.
twin welding hose
Welding hose: For gas welding, cutting and so on. The inner rubber material is mostly NBR or synthetic rubber, and the outer rubber is usually colored red, blue, yellow, etc. to indicate special gas..
Smoke exhaust hose
Ventilation hose: For hot gas, dust mist, smoke, chemical gas emissions and so on. The inner layer is mostly thermoplastic materials and PVC. Usually the tube body has a retractable design.
Road vacuum cleaner hose
Material suction hose: It is used for the transportation of fluids containing solid particles such as gas, mist, powder, granules, fibers, gravel, cement, fertilizer, coal dust, quicksand, concrete, gypsum, etc. The inner rubber materials are mostly NR, NBR, SBR and PU. Usually the outer rubber has higher abrasion resistance.
Petrochemical oil transport composite suction hose
Oil hose: For fuel, diesel, kerosene, petroleum, etc. The inner rubber materials are mostly NBR, PVC composite and SBR. Usually there is a conductive wire between the inner and outer rubber to prevent sparks.
High concentration chemical suction hose
Chemical hose: For acid, chemical solutions, etc. The inner rubber material is mostly EPDM. Often this class requires custom materials and designs..
