Equipment nozzle orientation
Thread Content
In the nozzle orientation diagram of the equipment, you can see how the saddle of the equipment can be divided into a fixed end and a sliding end. Aren't both saddles firmly fixed on the equipment cylinder? What position is this sliding end called a sliding end relative to, please help me, thank you!
The bolt hole at the sliding end is a long round hole, leaving room for thermal expansion or cold contraction of the cylinder. See saddle standard JB4712
This sliding refers to between the cylinder and the foundation, not between the saddle and the cylinder.
The most direct way to look at the sliding end is to look at the bolt holes on the base of the equipment. If it is a groove type, it is the sliding end, and if it is a round hole, it is the fixed end!
The relative fixed end is called the sliding end, and the fixed end is located on the side of the pipeline that allows less displacement.
The so-called sliding means that the support and the foundation can slide, not between the support and the cylinder. The purpose is to avoid the stress on the cylinder caused by thermal expansion and contraction, which has the same function as the expansion joint of the heat exchanger.
The bolt hole of the sliding saddle is a long round hole, and there is no specific requirement on which end it should be placed.； You can communicate with the user if they have any requirements in this regard. If not, you can place it freely. ；
Everything you said above is correct. The sliding end is a strip-shaped hole to allow space for the equipment to move when it expands due to thermal expansion or contraction.； The fixed end is a round hole ；
