One or four hose sizes
1., 4 branch pipes are 1/2 inch pipes; The 6 branch pipes are 3/4 inch pipes, and there are some differences in different specifications.
2. The so-called 5 to 4 should be different pipe diameters, that is, the specifications of pipes and pipe joints are different.
3. Corrugated pipe means that the pipe is not flat and has no ripple.
4, 1 inch =25.4mm, this is common sense.
Second, what material is good for rubber hose?
Threading hose
The threading hose is mainly made of galvanized steel belt, stainless steel belt, PA, PE, PP and other plastic materials. Uses: mechanical manufacturing, electrical threading hose. Wire and cable protection in 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 weight of the foot, without fracture or deformation, and can recover quickly. And there is no damage in itself.
stainless steel
Stainless steel hoses mainly refer to hoses made of 304 stainless steel or 30 1 stainless steel. Usage: stainless steel hose assembly for wire protection is used as automatic instrument signal? Stainless steel hose assembly hose. 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 shielding effect.
metal
Metal hose mainly refers to spiral corrugated pipe; The other is an annular bellows. Metal hose? flexible metal tubing
Spiral corrugated pipe is a tubular shell with spirally arranged corrugations. There is a spiral angle between two adjacent ripples, and all the ripples can be connected by a spiral.
The annular corrugated pipe is a tubular shell with closed annular corrugations, and the corrugations are connected in series through the annular corrugations. The annular corrugated pipe is made of seamless pipe or welded pipe. Limited by the processing method, the length of single pipe is usually shorter than that of spiral corrugated pipe. The advantages of annular bellows are good elasticity and low stiffness.
ripple
As a flexible pressure-resistant pipe fitting, corrugated hose is installed in liquid conveying system to compensate the mutual displacement of connecting ends of pipelines or machinery and equipment. Corrugated hose can absorb vibration energy, reduce vibration and noise, and has the characteristics of good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance and so on.
plastic
There are two kinds of plastic hoses, one is completely airtight and watertight, such as propellant transportation of launch vehicles, gas and water heaters; Another kind of plastic hose? Plastic hose is continuously wound with adhesive tape. Ordinary wound corrugated pipes are used to protect cables, such as magnetic card telephones, machine tools, etc., while the corrugated pipes of desk lamps are sandwiched with steel wires in the production process.
rubber
Rubber hose rubber hose is a kind of 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.
drainage
Drainage hoses mainly refer to hoses made of plastic or metal. Uses: mostly used for drainage.
Shower hose
Double hook hose, strong tension? (& gt 120? Kg), strong torque, ensure no crack, no water leakage. Shower hose? Shower hose
Comprehensive test: special PVC inner tube or EPDM inner tube? Through the comprehensive test of water pressure of 400PSI and 80 degrees.
Nut style: Nut styles are diverse. Nut material: copper or stainless steel.
Articulated: Articulated design is advanced, including fixed and 360-degree rotary. Joint material: copper or stainless steel.
Hose structure: the structure is firm and has passed the compression, tension and torsion tests.
Hose length: 1.2m, 1.5m, 1.8m, 2m.
Hose specification: 14mm? 16mm？ 17mm.
Surface treatment: electrolysis and electroplating.
Shower hose shell introduction: outer diameter 14mm and 16mm? 17mm bathroom hose shell is made of German machine tool, with real double buckle and never tripping. The shower hose has smooth surface, uniform gap, smooth hand feel, natural unfolding, firm structure, strong destructive resistance, pressure resistance greater than 25Kg, and tensile strength greater than 120Kg. The hose material is made of SUS304 stainless steel. The surface is treated by electrolysis and electroplating.
other
PA nylon hose (PA) is a high-tech product of corrugated pipe with imported modified raw materials. It has high toughness, high impact resistance, good bending performance, high temperature resistance, bright surface, friction resistance, chemical corrosion resistance, flame retardant and electrical insulation >: 200MΩ, halogen-free, environment-friendly and flame retardant, and is widely used in automotive wiring harness, electronics, mechanical wiring harness and other fields.
What I recommend to you today is the size and material classification of four-point hose. It can be seen that the common four-part hose is named according to the product parameters and specifications, and there are many corresponding material classifications, including threading hose, stainless steel hose, metal hose, composite hose and plastic hose. According to their specific needs, we can choose the corresponding classification or we can comprehensively understand it. What we explain for you is the introduction of hose material and size. I believe.
