304 stainless steel capillary pipe is a high-performance alloy steel pipe. 304 stainless steel capillary can resist corrosion in the air or various chemical substances, and it often has a smooth surface. But generally speaking, the stainless steel capillary pipe is mainly used as the supporting structure of various wire and cable protection tubes.
Stainless steel pipes can be applied to all kinds of automatic instrumentation signal tubes, automatic instrument wire protection tubes, optical ruler lines, industrial sensors, electronic equipment line protection tubes; the protection of electrical circuits, the protection of thermal instrument capillaries, and the inner core of high-voltage optical cables. It has good flexibility, corrosion resistance, high temperature resistance, wear resistance, tensile strength, water resistance and excellent electromagnetic energy. Stainless steel capillaries can be bent into various angles and radii of curvature, and have the same flexibility and durability in all directions. The stainless steel capillary pipe has flexible spacing, good flexibility, no obstruction and rigidity; the stainless steel threaded hose has a certain pulling force between the side buckles to prevent the hose from being damaged due to hose damage. The axial tension can withstand more than 6 times the nominal inner diameter. Therefore, the stainless steel capillary tube is easy to install, and low efficiency can be used to achieve the effect of energy saving.
(1) It is necessary to pay attention to whether the annealing temperature reaches the specified temperature. Stainless steel heat treatment generally adopts solution heat treatment, or "annealing", and the temperature range of this process is 1040-1120°C (Japanese standard). The stainless steel tube can also be inspected in the inspection hole of the annealing furnace during processing. The stainless steel tube in the annealing zone should be incandescent without sagging.
(2) There should be no water vapor in the furnace. One is to repeatedly check whether the furnace body is dry. When installing the furnace, the furnace body material must be dried; the second is to check whether the stainless steel pipe entering the furnace has residual water stains, and some stainless steel pipes may have holes. There must be no water brought into the bright furnace, otherwise it will have a negative impact on the stainless steel processing process.
