Regarding the treatment of the nozzle wall thickness when connecting it to the cylinder
Thread Content
In method A, the wall thickness of the fitting is made to fit tightly against the inside of the cylinder through gas cutting or wire cutting; in method B, no treatment is applied to the wall thickness of the fitting, only chamfering is performed. The question now is: 1) When to use Method A (Method B is commonly used in manufacturing). 2) What is the purpose and significance of adopting Method A? 3) If Method A is used, will its strength be lower than that of Method B? If Method A is adopted, is reinforcement of the pipe fittings then unnecessary? 4) What are the advantages and disadvantages of using Method B?

If there is interference with the internal components, Method A should be used, such as those with internal agitators, heat exchanger tube bundles, coiled tubes, etc. By using Method A, the strength requirements will also be met, and reinforcement of the connections is equally useful. Using Method B facilitates the processing of reinforcement pipes.
