Temperature regulation by desuperheater spray is an important part to ensure the stable operation of utility boiler. However, due to the bad working conditions, the spray pipe of Desuperheater will produce strong vibration, and the connected equipment will have alternating stress. At the same time, due to design or manufacturing reasons, abrasion or cracking occurs at the welding part or the contact part between the water spray pipe and other parts. Taking measures to ensure stable operation, reasonable design and qualified manufacturing can effectively guarantee the safe operation of power plant equipment.
