Introduction of tube sheet(tubesheet)
Recently we received an inquiry from a customer in Thailand,who specializes in the boiler industry.The product that the customers wanted is tube sheet(tubesheet),which is suitable for heater.This time,we will introduce the relevant knowledge of tube sheet accordingly.
Materials of tube sheet:
According to different environments and materials,A105/A350 LF2/Q345R (or equivalent material) plates are generally used,such as the first and second pressure vessels.There is no corrosive medium circulating.Carbon steel composite plates can be used. In the case of strong acid, high pressure and high temperature, nuclear energy and other environments, stainless steel,16 manganese,titanium alloy and other corrosion-resistant materials are needed.The application of new synthetic materials brings new vitality to tubesheet products.
Machining of tube sheet:
The tubesheet used in the third and fourth types of pressure vessels needs high accuracy.The traditional hole processing method is benchmarking and rocker drilling.With the large-scale chemical containers,the diameter and thickness of tubesheet are also increasing.CNC technology is also introduced into tubesheet processing.CNC drilling machine with rocker drill is widely used for drilling.The use of machining centers for high efficiency and high precision hole processing has gradually been accepted by some large enterprises.The demand for large thick tube sheets in nuclear power,seawater desalination,and central air conditioning heat exchangers is increasing.
Applications of tube sheet:
Tubesheet is widely used in chemical containers,such as tubular heat exchangers,pressure vessels,boilers,condensers,central air conditioners,evaporators,seawater desalination,to support the role of fixed tubes,metal materials make it not only has a strong rigidity,but also has a great heat conduction performance.
