Anti-corrosion steel pipe in the process of its use will be heat treatment, and the so-called heat treatment refers to the use of solution heat treatment, which is often referred to as "annealing" then when we are in the process of heat treatment what need to pay attention to it, the following anti-corrosion steel pipe factory with you to understand the next.
 

      Furnace hermeticity. The use of bright annealing furnace should be closed, isolated from the outside air; the use of hydrogen as a protective gas, only one exhaust port is through (used to ignite the discharge of hydrogen gas). Check the method can be wiped with soapy water in the annealing furnace at each joint gap, to see if the runaway gas; then in which * easy to runaway gas is the annealing furnace into the place where the tube and out of the tube, and this place the seal is particularly easy to wear, so in general we must often check often change.

      Annealing atmosphere. This is generally used pure hydrogen as the annealing atmosphere, and the purity of the atmosphere is better than 99.99%, if another part of the atmosphere is inert gas, the purity can also be a little lower, but can not contain too much oxygen, water vapor.
 
      Another point to note, that is, the furnace water vapor, which on the one hand in checking whether the furnace material is dry, especially in the initial installation of the furnace, the furnace material must be dried; second is into the furnace spiral steel tube whether too much water residue, especially if the tube above the hole, do not leak water into it, or else the furnace atmosphere all destroyed.
