What types of hoses are there?

Hose is an important industrial component, which is used as a wire and cable protection tube for wires, cables and automatic instrument signals and a civil shower hose. According to the classification of hose materials and uses, we are familiar with plastic hoses and rubber hoses. Let's look at the types of hoses.

What types of hoses are there?

① According to the purpose, it is mainly divided into threading hose, drainage hose, ventilation hose, shower hose and harness hose.

② According to materials, it is mainly divided into stainless steel hoses, metal hoses, corrugated hoses, rubber hoses and plastic hoses.

Several main types of hoses are introduced below.

① threading hose: mainly made of galvanized steel belt, stainless steel belt, PA, PE, PP and other plastic materials. Uses: wire and cable protection in machinery manufacturing, electrical insulation protection, lighting equipment, automobile manufacturing, aviation equipment, subway, train, automation control and other industries. Features: good flexibility, anti-twisting, good bending performance, able to bear heavy loads; Acid resistance, lubricating oil, coolant, etc. The surface is shiny and resistant to friction. Can bear the heavy pressure of stepping on the foot, does not break or deform, can recover quickly, and has no damage itself.

② Bellows: As a flexible pressure-resistant pipe fitting, it is installed in the liquid conveying system.

It is used to compensate the mutual displacement of the connecting ends of pipelines or machinery and equipment, absorb vibration energy, and has the function of reducing vibration and noise. It has the characteristics of good flexibility, light weight, corrosion resistance, fatigue resistance and high and low temperature resistance. ③ Stainless steel hoses: mainly refer to hoses made of 304 stainless steel or 30 1 stainless steel. Usage: used as wire protection element hose for automatic instrument signal. Stainless steel hose for protecting precision optical ruler and sensing circuit. It has good flexibility, corrosion resistance, high temperature resistance, wear resistance, tensile resistance and water resistance. And provides a certain masking effect.

④ Plastic hoses: There are two kinds, one is completely airtight and watertight, such as propellant transportation of launch vehicles, gas and water heaters; The other is continuous winding with adhesive tape. Ordinary wound corrugated pipes are used to protect cables, such as magnetic cards, telephones, machine tools, etc., while the corrugated pipes of desk lamps are sandwiched with steel wires during production.

⑤ Rubber hose: It is a steel wire braided hose. The rubber hose consists of an inner rubber layer, a steel wire braided layer and an outer rubber layer. Suitable for conveying hydraulic fluids, such as alcohol, fuel, lubricating oil, emulsion, etc.

The shower hose is familiar to us. There are two kinds of hoses, plastic hoses and metal hoses, which are common in ordinary families. Although other types of hoses are unfamiliar, they play an important role in invisible places in our lives.
