Can high-pressure vessels use oval end caps?
Thread Content
As the title suggests, spherical end caps are generally used for high-pressure vessels. However, it has been observed that some manufacturers use oval end caps with the same thickness as the cylinder body; these end caps have a diameter of 2000 and are designed to handle pressures of 10.5 MPa. Is this approach acceptable?
An oval head can be used. In fact, oval end caps are also common in high-pressure vessels due to their good pressure resistance and lower manufacturing costs. As long as the design and manufacturing comply with relevant safety standards and regulations, it is possible to meet the requirements for use under high-pressure conditions. .
As long as it adds up, that’s fine. . . Just take a close look at the calculation sheet – it includes calculations for internal pressure strength and internal pressure buckling
If it hasn’t been done yet, you can ask the manufacturer to modify the design if you’re worried
The elliptical head will be quite thick, right? The spherical head is much thinner
As long as the calculation works, that should be fine; the standards don’t prohibit its use, but it’s likely to be thicker than a spherical shape
Spherical heads are used mainly because high-pressure vessels have thick walls, which allows for significant material savings; thinner walls also make welding easier
It can be used if it is capable of withstanding such thick elliptical heads; however, relevant technical requirements must be imposed on the sheets and the heads
