The paper also provides an example of a finite element analysis (FEA) of a top nozzle, a FEA of a pair of lifting trunions and a FEA of welded on lifting lugs for buried pipe.

The paper also discusses different types of lifting lugs that may be attached to each end of the vessel either by bolting or welding and discusses the pros and cons of each. Pin D mm Inside Width W mm Inside Length Width of Bow B mm Approx. This paper identifies the types of evaluations that must be performed to determine the stresses in the vessel and lifting attachments during the lifting. For design of the liftlug & attachment weld to vessel, we use the same factor of safety as for MSS Under the Hook Lifting device. Therefore, the design parameters should consider safe load conditions. Planning well in advance of the lift date is required.Careful consideration must be given to the choice and design of attachment to the pressure vessels used for the lift to ensure that the vessel and lifting components are not overstressed during the lifting process. The lift lug is a non-pressure attachment, & is not in use when vessel is operating. Equipment for the handling heavy reactors and large diameter pressure equipment is usually scarce, expensive. The lifting gear should be suitable for platform lifts only according to this guideline. These pressure vessels are usually fabricated in shops dispersed globally and require unique heavy duty equipment for their safe handling, transportation and erection.The challenge is to find a safe, efficient and cost effective solution based upon the limitations of the equipment, job site and the lift equipment available for erection. in some special cases the lifting lugs may partly be located on the lifting cradle and partly on the equipment to be transported NOTE Lifted objects stowed in a container may have its own lifting gear. Today, 800 ton to 1,500 ton reactors and or large diameter vessels with diameters ranging up to 15 meters are common in the refining industry. The Infiltrator IM-1060 is a lightweight strong and durable septic tank. AbstractHeavy wall reactors and large diameter pressure vessels usually face unique challenges in their erection onto their foundations at the jobsite. inboard lifting lugs allow for easy delivery and handling.
