Hose classification

According to the purpose, it is mainly divided into: threading hose, drainage hose, ventilation hose, shower hose, and wiring harness tube.
According to the material, it is mainly divided into: stainless steel hose, metal hose, corrugated hose, rubber hose, and plastic hose.
Threading
Threading hoses are mainly made of galvanized steel strips, stainless steel strips, PA, PE, PP and other plastic materials. Uses: wire and cable protection in machinery manufacturing, electrical insulation protection, lighting equipment, automobile manufacturing, aviation equipment, subways, trains, automation control and other industries. Features: good flexibility, anti-twisting, good bending performance, can withstand heavier loads; acid-resistant, lubricating oil, coolant, etc., with a glossy surface and friction resistance. It can withstand the heavy pressure of footsteps without breaking or deforming, can recover quickly, and has no damage itself.
Stainless steel
Stainless steel hoses mainly refer to hoses made of 304 stainless steel or 301 stainless steel. Uses: used as wire protection hoses for automation instrument signals. Stainless steel hoses used to protect precision optical rulers and sensor lines. It has good softness, corrosion resistance, high temperature resistance, wear resistance, tensile resistance, and waterproofness. And it provides a certain shielding effect.
Metal
Metal hose mainly refers to one type of spiral bellows; the other type is annular bellows. Spiral bellows is a tubular shell with corrugations arranged in a spiral shape. There is a spiral rise angle between two adjacent corrugations, and all corrugations can be connected by a spiral line.
Annular bellows is a tubular shell with corrugations in a closed circular ring shape, and the waves are connected in series by circular ring corrugations. Annular bellows are formed by seamless pipes or welded pipes. Due to the processing method, the length of a single tube is usually shorter than that of a spiral bellows. The advantages of annular bellows are good elasticity and low rigidity.
Corrugation
As a flexible pressure-resistant pipe fitting, the corrugated hose is installed in the liquid transportation system to compensate for the mutual displacement of the connection ends of pipelines or machines and equipment, absorb vibration energy, and can play a role in vibration reduction and silencing. It has many characteristics such as good flexibility, light weight, corrosion resistance, fatigue resistance, and high and low temperature resistance.
Plastic
Plastic hoses are divided into two types. One is completely airtight and watertight, such as for the delivery of propellants for launch vehicles, gas, and water heaters; the other is continuously wound with strips. Ordinary wound bellows are used to protect cables, such as magnetic card telephones and machine tools, while the bellows of table lamps are clamped with steel wire during the production process.
Rubber
Rubber hoses are steel wire braided hoses. The 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, emulsions, etc.
Drainage
Drainage hoses mainly refer to hoses made of plastic or metal. Uses: mostly used for drainage.
Shower
Double hook hoses, strong tensile force (>120Kg), strong torsion, to ensure no cracking and no water leakage.
Comprehensive test: special PVC inner tube or EPDM inner tube passes the comprehensive test of water pressure 400PSI and 80 degrees
Nut style: Nut style is diverse. Nut material: copper or stainless steel.
Connector style: The connector style is advanced in design, with fixed type and 360-degree rotating type. Connector material: copper or stainless steel.
Hose structure: The structure style is firm and has passed the compression, tension and torsion tests.
Hose length: 1.2 meters, 1.5 meters, 1.8 meters, 2 meters.
Hose specifications: 14mm 16mm 17mm.
Surface treatment: electrolysis, electroplating
Shower hose shell introduction: The outer diameter 14mm and 16mm 17mm bathroom hose shell is made by German machines, with real double buckles and never disengagement. The shower hose has a flat surface, uniform gaps, smooth feel, natural expansion, firm structure, strong anti-destructiveness, pressure resistance greater than 25Kg, and tensile resistance exceeding 120Kg. The hose material is made of SUS304 stainless steel. The surface is treated with electrolysis and electroplating.
Others
PA nylon hose (PA), made of imported modified raw materials, is a high-tech product of corrugated pipes, with high toughness, high impact resistance, good bending performance, high temperature resistance, bright surface, friction resistance, chemical corrosion resistance, flame retardant, electrical insulation > 200MΩ, halogen-free, environmentally friendly and flame retardant, widely used in automotive wiring harnesses, electronics, mechanical wiring harnesses and other fields.
