500-ton crane lifting 80-ton DN3100mm pipeline
Thread Content
On January 6, 2023, at the construction site of the Tianjin Nangang ethylene project, a DN3100 mm pipeline weighing 80 tons was hoisted into place between the quench oil tower and the quench water tower, marking the entry of the project into the peak phase of pipeline installation work. The DN3100 mm pipeline to be lifted this time has a length of approximately DN3100×40,000 mm. Its diameter is 3100 mm, and its net weight is 80 tons. It consists of a straight section of pipe along with a bend. Due to its large diameter and length, on-site assembly and welding were employed. To ensure the successful lifting, a XCMG 500-ton truck crane was used as the main lifting device, while a Sany 400-ton truck crane was used to assist with the lifting process.
I was fortunate to be involved in the design of these two towers
In the past, such large items were all bought from foreigners
Looking at the photos, there are saddles pre-installed under this pipe; is it intended to be connected to the vertical pipe next to the tower on the left? Considering the several columns that are reserved at the top of the steel structure but not yet installed, should this pipe be lifted as a whole onto the platform at the top of the steel structure? No wonder such large cranes had to be used for lifting.
In the interweaving of time and space, many people pass by each other! I never expected it to be such an expert
:Handshake, impressive! The leader is indeed a role model for us all!
