Q:What is the essential difference between silicone tube and rubber tube?
Silicone tube 100% non-toxic, tasteless, fine silk, silicone silicone tube (article), high pressure resistant silicone tube, silicone tube, gear shaped sealing strip, shaped article, food grade (non-toxic) silicone tube (article), medical silicone tube, silicone tube, silicone tube medicinal woven (used for conveying working pressure, liquid food, pharmaceutical and biological products. ) medical silicone pipe joint, silica gel sealing tube, flame retardant tube (strip), silica gel foamed pipe (strip), high temperature resistant silicon rubber tube, performance: cold resistance, high temperature resistance. Harmless non-toxic and tasteless; suitable for small household appliances (coffee pot, kettle, electric iron, electric cooker, frying pan, disinfection cabinet, drinking machine, pulp machine, bread machine, gas cooker, water heater) and electronic, automobile, medical and other mechanical products.
Q:How to remove hose odor?
The hose structure is usually divided into: inner layer, outer layer and skeleton layer (or middle layer). The inner layer directly bears the abrasion and erosion of the conveying medium; the outer rubber layer protects the inner part of the hose from the damage and erosion of the external environment; the skeleton layer is the pressure bearing layer of the rubber tube, and gives the strength and rigidity of the pipe body. The working pressure of the hose depends on the material and structure of the skeleton.
Q:What is the difference between the precast beam of the bridge and the method of pulling out the rubber tube after pouring the concrete? What's the difference between design and calculation?
Construction process, in order to avoid concrete into bellows, influence later wear steel strand, construction units generally use PVC and other rubber tube into bellows, in order to double insurance, don't let concrete into. Its length is certainly larger than the length of bellows (750mm at one end for easy operation)
Q:Is the rubber pipe joint installed in the middle of the pipe and pump to absorb the shock?
A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:How can the hose of natural gas be connected to the water heater?
One end is connected to the water heater, the other end is connected to the gas pipe, and the other end of the gas pipe needs to be equipped with three through. Are you installing it yourself? Why don't you find the man who installed the water heater to put you through? Suggest that you still find professionals to connect, so that relatively safe. Hope to be of help to you.
Q:What are the types of cable metal hose connections?
It is mainly used for connecting the box and hose in place. Open the box in the box and plug into the joint. The external thread joint is fixed with the lock.
Q:Plastic metal hose connector model specification, who knows?
Package type plastic hose is many, the most common is the DPJ thread joint, DPN joint, DKJ card connector, DGJ self fixed joints, Glenn joints, fittings
Q:How long is the service life of a rubber tube?
It depends on the environment, and what brand of hose, the general import of plastic pipe used relatively long, our family's sewage pipe with IVG used for several years
Q:What are the categories of hose?
A rubber hose products structure: hose cloth; woven hose (fiber braided hose, steel wire braided hose); winding hose (fiber winding hose, hose winding wire); knitted hose, hose and other circular weaving hose (rubber hose, rubber and plastic composite hose and hose, drilling hose, etc.).
Q:What's the metal hose for fire fighting?
The main parts of production material is austenitic stainless steel hose, thus ensuring the heat resistance and excellent corrosion resistance of the hose, the hose working temperature range is very wide, is -196 - 600 degrees, use the hose on pipeline through corrosion for stainless steel plates, to ensure that the corrosion resistance of hose.
