The Point And Use Of Various Kinds Of Hose
Threading hose is mainly made of galvanized steel strip, stainless steel belt, PA, PE, PP and other plastic materials made of hose. Use: wire and cable protection in industries such as mechanical manufacturing, electrical insulation protection, lighting equipment, automobile manufacturing, aviation equipment, subway, train, automation control and other industries.
Characteristics: good flexibility, anti distortion, good bending performance, can withstand heavier loads, acid resistant, lubricating oil, coolant, etc., with luster and friction resistance. It can withstand the heavy pressure of the foot, do not break and remain unchanged, and can recover quickly, and there is no damage to itself.
Stainless steel hose
Stainless steel hose mainly refers to materials made of 304 stainless steel or 301 stainless steel hose. Purpose: wire protection hose for automatic instrument signals. Stainless steel hose for protecting precision optical ruler and protecting sensing circuit. It has good softness, corrosion resistance, high temperature resistance, abrasion resistance, tensile resistance and water repellency. And provide a certain shielding effect.
A metal hose is mainly a spiral corrugated pipe, and the other is a corrugated bellows. A spiral bellows is a tubular shell with a spiral arrangement of corrugations. There is a spiral angle between the two adjacent ripples. All the corrugations can be connected by a spiral.
Circular bellows are corrugated tubular shells with corrugated edges. The waves are connected in series with circular waves. Annular bellows are formed from seamless pipes or welded pipes. Constrained by the processing method, the length of the single tube is usually shorter than that of the spiral corrugated pipe. The advantages of annular bellows are good elasticity and small rigidity.
As a flexible pipe fittings, the corrugated hose is installed in the liquid conveying system to compensate for the mutual displacement of the pipe or machine and equipment, absorb the vibration energy, and play the role of vibration damping and silencing. It has many characteristics such as good flexibility, light weight, corrosion resistance, fatigue resistance and high and low temperature resistance.
There are two kinds of plastic hose, one is fully air tight and water tight, for example, propellant transportation for launch vehicle, gas and water heater, the other is continuous winding with material, common winding bellows used to protect cable, such as magnetic card telephone and machine tool, and the bellows of table lamps are sandwiched in the production process.
Rubber hose and rubber hose are wire braided hose. The hose consists of an inner glue layer, a steel wire braided layer and an outer rubber layer. It is suitable for conveying hydraulic fluid, such as alcohol, fuel oil, lubricating oil, emulsion and so on.
Drainage hoses are mainly made of plastic or metal hoses. Use: more for drainage.
Double hook hose, >120 Kg, strong torque, ensure no crack, no leakage.
Comprehensive test: special PVC inner tube or EPDM inner pipe is tested by water pressure 400PSI and 80 degrees.
Nut style: nuts are of various styles, with fixed type and 360 degree rotary type. Nut material: copper or stainless steel.
Connector style: advanced connector design, fixed type and 360 degree rotary type. Joint material: copper or stainless steel.
Hose structure: solid structure, through compression, tensile and torsion testing.
Hose length: 1.2 meters, 1.5 meters, 1.8 meters, 2 meters.
Hose specification: 14mm 16mm 17mm.
Surface treatment: electrolysis and electroplating
Introduction of shower hose tube: outer diameter 14mm and 16mm 17mm bathroom hose tube made of German machine, real double button, never tripping. The sprinkler hose has smooth surface, uniform clearance, smooth handle, natural expansion, strong structure, strong resistance to destruction, resistance to pressure more than 25Kg, tensile strength more than 120Kg. The hose material is made of SUS304 stainless steel. The surface is treated by electrolysis and electroplating.
