stainless steel 304 capillaries Tubes 


stainless Steel 304 capillary tube can be applied to all kinds of automatic instrumentation signal tube, automatic instrument wire protection pipe, precision optical ruler line, industrial sensor, electronic equipment line protection pipe, electrical circuit safety protection, thermal instrument capillary protection and empty core high-voltage optical cable internal support.


304 characteristics of stainless steel capillary It has good softness, corrosion resistance, high temperature resistance, wear resistance, tensile strength, water resistance and excellent electromagnetic shielding properties. Stainless steel capillaries can be freely bent into various angles and curvature radii, with the same softness and durability in all directions. Stainless steel Hose spacing is flexible, good flexibility, no obstruction and stiffness; stainless steel threaded hose has a certain tension between the side buckle to prevent the hose from being damaged by hose damage. Axial tension can withstand more than 6 times times the nominal inner diameter.


Therefore, the installation of stainless steel capillary tube is convenient, inefficient energy can be used effectively, in order to achieve energy saving and comfortable effect.


304 stainless Steel Capillary steps in the event of annealing 1, need to pay attention to whether the annealing temperature reached the specified temperature. Stainless steel heat treatment is generally to accept solid-soluble heat treatment, or "annealing", the temperature range of the process is 1040~1120 (Japan specification).


Stainless steel pipe processing can also be viewed in the annealing furnace, the annealed stainless steel pipe should be incandescent shape, and there is no softening droop phenomenon. 2, annealing atmosphere.


Generally with pure hydrogen as a stainless steel pipe annealing atmosphere, the atmosphere purity is preferably more than 99.99%, if there is another inert gas in the atmosphere, can appropriately reduce the purity of pure hydrogen, but prohibited to contain excessive oxygen and water vapor. 3. Sealing of furnace body. The light annealing furnace must be confined to the outside air, usually with hydrogen as a maintenance gas, the furnace body only one vent is through, the role is convenient to ignite hydrogen.


The method of inspection will wipe the water at the gap of each joint of the annealing furnace, observe whether there is air leakage, the most easily leaking part is the annealing furnace in and out of the pipe place, where the sealing ring is very easy to wear, need to be checked and replaced frequently. 4, maintain the gas pressure. To avoid leakage, the maintenance gas in the bright furnace should maintain a certain positive pressure, if the maintenance gas is hydrogen, generally to reach more than 20kBar. 5, there can be no water vapor in the furnace.

First, to repeatedly check whether the furnace body is boring, in the first furnace, furnace material must be dried, the second is to check whether the stainless steel pipe into the furnace has residual water stains, some stainless steel tubes may have holes, at this time must not have water to bring into the bright furnace, otherwise it will have a negative impact on the stainless steel processing process.
