Advantages of pre-fabrication
① In a controlled environment, the quality of work is easier to manage and maintain.
②Specify tolerances, high precision, and avoid on-site rework.
③ Manufacturing is not affected by the weather, so production delays can be minimized.
④The prefabrication process is the best advantage, because it provides less labor for the on-site manufacturing of spools.
Compared with on-site manufacturing, the manufacturing cost of mass production is lower.
⑤The prefabricated valve core requires less manufacturing and assembly time, so that extra time and cost waste can be avoided.
Prefabricated spools do not require users to invest in production and testing equipment. In order to obtain better and more effective performance, radiography, PMI, MPI, ultrasonic testing, hydraulic testing, etc. can be used.
⑥ In order to reduce the possibility of on-site rework, the welding parameters must be better controlled in a controlled environment.
