Hot pressed elbow can be treated by quenching and normalizing.
Quenching is a method of heating the elbow above the critical temperature, holding it for a period of time, and then quickly putting it into the quenchant to suddenly reduce its temperature and rapidly cool it at a speed greater than the critical cooling speed.
Quenching can increase the strength and hardness of steel, but reduce its plasticity. Quenchants commonly used in quenching include water, oil, alkaline water and salt solution.
Normalizing is a heat treatment method that heats the hot pressed elbow to above the critical temperature, transforms all the hot pressed elbow into uniform austenite, and then cools naturally in air.
It is economical to use normalizing instead of quenching process for elbow with low requirements.
Hot push elbow is used where the direction of pipeline needs to be changed, so it is widely used. It is mainly used in chemical, civil, Petroleum,chemical,power,gas,metallurgy,shipbuilding,construction.etc.
