Special hoses for furnace doors are suitable for a variety of industrial fields, such as the food and beverage industry. These hoses are used to transfer a wide variety of liquids, including milk, potable water, orange juice, carbonated beverages, and more. They are also used to transfer chemical substances like paints, salt solutions, varnishes, etc.
Which working conditions are the furnace door cooling hoses suitable for?
Special hoses for furnace door cooling are suitable for a variety of industrial fields. They provide cooling and protection against corrosion, contamination, and other hazards. However, these hoses are not suitable for all types of pressure work, such as in vacuum and pressure applications. These situations call for special high-pressure probes and capillary devices.
The materials used in the manufacture of these hoses should be suited to the application. For example, ordinary carbon steel has a low impact strength at low temperatures, which can lead to failure at weak points. Moreover, the temperature dependence of volumes must be taken into account when designing combinations of materials. This way, leaks can be avoided. In addition, O-rings that provide a good seal at room temperature may lose their resilience when used in chilled equipment.
These hoses should be installed and maintained in a well-ventilated place. They should not be stored near flammable liquids or sources of ignition. Moreover, the cylinders must be grounded to prevent static electricity buildup.
Hot plates are commonly used in laboratories. They are safer than steambaths. But the heating element of these devices must be enclosed to avoid the risk of ignition and electric shock. Almost all hot plates nowadays meet this criterion. However, there are some older models that may pose an electrical spark hazard.
The inner layer of special hoses for furnace doors cooling
To withstand the extreme temperatures found in these applications, the inner layer of special hoses for furnace doors is made from fiberglass. Its two-ply fiberglass cover resists heat and is resistant to steel splashes and electrical shock. The hose is also lightweight for easy handling.
This hose can be used in many industrial areas. It does not contain a refractory layer, which eliminates weight and time-consuming maintenance. It also has a patented design that helps it fit a wide range of furnace doors.
The main raw materials for special hoses for furnace doors cooling
Furnace door cooling hoses are special hoses used for carrying cooling water inside furnace doors. They are available in a variety of nominal outer diameters and temperature ranges. They are made from SBR synthetic rubber and are covered with a fiberglass fabric ply. They also come with four spiral-ply synthetic fabric reinforcements. They are well-suited for the harsh environments found in steel mills.
Fluoroelastomer (FKM) is a thermoplastic material that is resistant to temperature extremes. Fluorine content can reach 66%, increasing its resistance to fluids. Butyl rubber tubing can be used in high temperatures and is an excellent choice for carbon dioxide and air transfer. Its thick walls make it shock-absorbing and resistant to oxygen degradation.
Copper is also a good choice. Copper is more thermallyconductive than steel and can remove heat better. It can be used in applications that require energy efficiency. Copper is a very durable material, and has been used in various industries for over a century.
