Low-temperature vessel saddles and anchor bolts
Thread Content
It is a horizontal container with a medium temperature of -130 degrees; the equipment is made of 304 stainless steel. How should the foundation bolts be considered, and what material is suitable for them? Additionally, it is planned to install thermal insulation blocks directly between the saddle and the concrete foundation. This has not been done before; could someone please explain in detail the structure of such thermal insulation blocks or their standard models, or provide drawings of them? Thank you!
It should be for vacuum interlayer equipment! Supports and footings should be designed considering the ambient temperature!
The material for anchor bolts is selected based on the ambient temperature
Use 9Ni or austenitic stainless steel
For details, see the official account \"Chemical Equipment Innovation Base\"
The foundation bolts should be sized using the lowest value of the monthly average minimum temperatures over the years, plus 20°
Excuse me, which standard does this fall under?
Most devices do not have anchor bolts; instead, they are welded in place, or fixed using screws that do not meet the required standards. The selection of foundation bolts is guided by GB/T 799-2020; the requirements are usually specified in the drawings.
The foundation bolts are selected for normal temperature conditions; the thermal insulation blocks consist of two plates at the top and bottom, with wooden planks impregnated with asphalt or polyisocyanurate placed in between
