For the heads of high-pressure pressure vessels with a large diameter (when DN＞4000), a method of first forming them and then welding them together can be employed
For the heads of high-pressure pressure vessels with a large diameter (when DN＞4000), the method of forming first and then welding them together can be used (correct).
For the heads of high-pressure pressure vessels with a large diameter (when DN＞4000), the method of forming first and then welding them together can be used (incorrect). It should be the low-pressure pressure vessel head when DN>4000
For the heads of high-pressure pressure vessels with a large diameter (when DN＞4000), the method of forming first and then welding together can be adopted (X).
For the heads of high-pressure pressure vessels with a large diameter (when DN＞4000), the method of forming first and then welding them together can be used (Incorrect)
Correct---------------------
Answer: Correct, it should be possible
For the heads of high-pressure pressure vessels with a large diameter (when DN＞4000), the method of forming them first and then welding them together can be used() This is correct
