304 stainless steel capillary tube can be applied to a variety of automation technology instrumentation data signal tube, instrumentation cable cable protection tube, high-precision electronic optics ruler line, industrial sensors, electronic products line protection tube; household appliances line of safety precautions, thermal instrumentation capillary safety protection and empty core high voltage fiber optic cables. Support point.
Characteristics of 304 stainless steel capillary tube
It has excellent flexibility, corrosion resistance, heat resistance, abrasion resistance, compressive strength, abrasion resistance and excellent magnetic shielding material properties. Stainless steel capillary tube can be bent into a variety of angles and angles, in all directions with the same flexibility and durability. Stainless steel hose interval flexibility, good flexibility, no blocking and bending stiffness; stainless steel plate mounted line plastic hose in the middle of the side buckle with a certain amount of tensile strength to avoid plastic hose damage due to plastic hose damage. Radial tensile force can bear beyond the tolerance nominal diameter of about 6 times. Thus, the stainless steel capillary tube is easy to install, inefficient kinetic energy can be reasonably used to do environmental protection and energy saving and comfortable practical effect.
304 stainless steel capillary tube in the descending burn process
1, must pay attention to the annealing temperature is not to do the required temperature. Stainless steel plate tempering treatment is generally accepted solid solution tempering treatment, or "quenching", the temperature range of the process is 1040 ~ 1120 ℃ (Japan's national standards). Pipe production and processing can also be viewed in the quenching furnace view holes, quenching area of the steel pipe should be incandescent shape, and no softening and relaxation of the situation.
2, quenching atmosphere. Generally pure hydrogen as the quenching atmosphere of the steel pipe, the best atmosphere purity of 99.99% or so, if there is another inert gas in the atmosphere, you can moderately reduce the purity of pure hydrogen, but it is strictly prohibited with an excessive amount of oxygen cylinders and water gas.
3, furnace wall airtight. Bright quenching furnace must be airtight and external gas barrier, generally to radon gas when the maintenance of the vapor, the furnace wall can only be an air outlet is open, the effect is to facilitate the ignition of radon gas. Check the way the water will be smeared in the quenching furnace of each connection head gap, observe and check whether there is no leakage of steam, in which the most very easy leakage of steam is the quenching furnace in and out of the pipeline in the region, where the sealing ring is easy to damage, and must be often checked and dismantled and replaced.
4, maintain the gas working pressure. To prevent vapor leakage, bright furnace maintenance gas should maintain a certain standard gas pressure, if the maintenance gas is radon gas, a wide range to do about 20kBar.
5, the furnace can not have moisture. First, we must constantly check the furnace wall is not dry and tedious, in carrying out the initial loading of the furnace, the raw materials of the furnace wall must be air-dried; Second, we must check the steel pipe into the furnace is not residual water stains, some steel pipe will have holes, then dry million can not have stored water to bring to the bright furnace, otherwise it will lead to the whole process of stainless steel processing adverse effects.
