Abstract: This paper mainly introduces the technical index of material, the method of testing, the control
of weld craftwork and inspection while manufacturing the high p ressure heat exchanger made of the steel
SA336F22CL3. It has been finished the high p ressure heat exchangerwell by adop ted reasonable welding,
treatment and p rocedure of fixing, and ensured the quality of p roduct, all the machines include the resist
temper embrittlement capability meet the requirement of the bluep p letely, it p rovided the refer
ence effect on the home manufacturing of the key equipments.
