Q:How can the rubber tube be used properly and how to use it properly?
The hose burst caused by frequent and severe pressure impact. This situation is not generally under the static pressure caused by too much, but the number and intensity and pressure impact. Engineering machinery in operation, will be repeated in the hydraulic tubing suddenly increased or decreased, which impact on the oil pressure of frequent the damage of the oil seal, resulting in increased, loosening hose leakage and rupture foaming and pipe joint. Therefore, in operation, the valve stem can not be too hard, must be gentle.
Q:The copper joint is leaking, and the tap water hose and copper joint are leaking
It is suggested that the material used for piping may be better. At least the same material
Q:In long-term high temperature environment, silica gel tube and three yuan ethylene propylene rubber hose which is good durability?
Others, such as three yuan ethylene propylene and nitrile rubber hose, are basically black. Long term use of plastics can cause fading and deformation. The chemical properties of silica gel are stable and the physiological inertia is good. They are very resistant to biological aging, have no rejection reaction with limbs, and have better anticoagulant properties.
Q:What's the cause of a default like a general rubber product?
It's aging of rubberAging refers to the polymer materials (including rubber, plastics, fiber and so on) in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors, its performance gradually deteriorated, resulting in the final loss of use value.
Q:What kind of material is medical rubber tube?
Silicone rubber, of course, is environmentally friendly, non-toxic, harmless, such as high-pressure sealing ring in the pot. First of all, to the human body non-toxic first.
Q:How to detect the reliability of rubber hose
Suction flat test: in the 1min vacuum, after maintaining 10min, with diameter of 0.9 times the diameter of the hose rolled over, check the degree of collapse of the hose. Some standards used to measure the rate of change in the outer diameter of the hose to indicate the extent of deformation of the hose.
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?
Corrugated pipe is included in the design of the amount of engineering, the role is: reserved strand space. Its length is calculated when the work length of the steel strand.
Q:Which is better for binding files with rubber tubes and cotton threads?
In fact, the most suitable binding file is the file department I twine, such units are preserved, just to have you asked, hope to adopt
Q:What are the types of metal hose couplings?
DKJ jointStructure and characteristics:The DKJ card sleeve type metal hose joint can connect the steel pipe without the screw and the hose, and save the thread setting process, just screw the screw in;The metal joint is made of zinc alloy. The surface is zinc plated, sanded or chrome plated. The structure is compact and the strength is high. The steel pipe and the metal hose are connected reliably, and the appearance is beautiful;The metal fittings are jacketed to connect the metal hose to the non threaded steel tube;Suitable metal hose: JS, JSH, JSB, JSHG;Adaptation: steel thin steel wire pipe, black, tin pipe (water, gas);When choosing DKJ card type metal joint, please pay attention to the specification and size of the connecting pipe hose.
Q:The difference between hose and rubber tube
Rubber tube: characteristics of rubber tube has physiological inertia, UV resistance, ozone resistance, resistance to high temperature (-80 to 300), high transparency, strong resilience, resistant to compression permanent deformation, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame resistance, voltage, conductive properties. In fact, silicone hose is also a rubber tube, resistant to oil, heat.
