Oval manhole

Release time: October 23, 2017
 Oval manhole

The oval manhole and handhole are opened in the container to check the internal space of the container, clean the inside of the container, and install the accessories in the disassembly device. The commonly used manhole or handhole is not round or oval.


The advantage of oval manhole is that the hole area on the wall can be smaller. The elliptical manhole of vertical vessel is generally opened on the cylinder body, because the short diameter of the elliptical hole can be placed on the axis direction of the container, which can not only reduce the weakening of the cylinder strength caused by the opening, but also be suitable for people to enter and leave (because the manhole is wider in the horizontal direction and narrower in the vertical direction). For horizontal vessels, the manhole on the cylinder shall be round, and the elliptical manhole shall be opened only on the dished head.


Specification parameters of oval manhole:

Material: 304 (1.4301)
