Q:How about rubber transfusion hose?
The last step is to protect the sulfide layer to remove the wound hose and then taking care, and pipe fittings withhold, then you can test the pressure sampling
Q:The difference between silicone tube and PVC tube?
Silicone hose is also a kind of rubber tube, resistant to oil and heat. Because of the different types of rubber rubber pipe has many applications, commonly used rubber tube material EPDM, CR, VMQ, FKM, IIR, ACM, AEM, common structure with single, double, multilayer, enhanced, non enhanced etc..Silicone hose is the biggest feature of resistance to temperature changes of -60 degrees to 250 degrees, but the cost is very expensive, PVC is often used as ordinary water pipes, temperature sensitive, cheap and delicious, suitable for general working environment, no requirement for hoses. Compression resistant silicone hose can also withstand pressure, PVC in general, depends on the wall thickness and caliber. These are the differences between the silicone tube and the PVC tube.
Q:Do I need a shim for the flat metal hose joint?
If one of the two interconnected joints is one of those with a groove and a O ring, it would be better to put the O ring in it and seal it better.
Q:How can the rubber joint be classified according to the range of temperature?
A universal rubber flexible joint is suitable for use in water from -15 DEG C to 80 DEG C or in a variety of acid and alkaline solutions with concentrations below 10%.
Q:Why should the water stop strip be joined by heat instead of superposition?
Lap joint of rubber water stop belt is lap joint, this method is not allowed in engineering, glue glue and do not use overlay. In the case of splicing, it is equivalent to not doing any treatment at the joint. In the process of pouring, the sealing strip is prone to roll and twist.
Q:Is rubber tube harmful to drinking water?
There are drinking water standard rubber tube, ordinary hose can not be directly applied to drinking water, there is low toxicity!
Q:How to detect the reliability of rubber hose
Hydraulic test verification pressure test: Test hose and assembly under verification pressure, continue 30s-60s, whether to produce leakage, deformation and damage. Compression deformation test: keep 1 minutes under the specified pressure (work pressure, verification pressure or other pressure below the proof pressure), measure the length and diameter of the hose, twist angle and bend. Bursting pressure test: Determination of the pressure at which the hose burst during the specified step-up rate. Leak test: save 5min at 70% of the minimum blast pressure, and check again and again for leaks or damage. Due to the fact that water is often used in tests, the pressure and leakage pressure at normal temperatures may be slightly lower at normal temperatures.
Q:Why does Br2 corrode rubber tubes?
Br2 bromine gasBr2 bromine element at room temperature is dark brown liquid, soluble in water, 100g water can dissolve about 3G bromine. Highly volatile, toxic, steam strongly stimulate the eyes, mucous membranes and so on. The water solution is called bromine.
Q:Hose connector JB1885-77 what is the standard?
GB A flat joint core series hose assembly standard.
Q:What are the main differences between stainless steel flexible joint and rubber soft joint?
High water use of this product, the pipeline must be fixed or fixed support bracket, otherwise the product should install anti pull off device. The force of fixed support or bracket must be greater than the axial force, or should install anti pull off device. And because the metal hose pressure resistance better, do not need to install.
