Industrial Petrochemical Steel Structure Grid High-rise Building

product Description

structural composition

Frame columns: mainly bear vertical loads and bear vertical and horizontal loads from beams, equipment, etc.

The cross-section size is determined according to calculation for hot-rolled or welded wide flange H-section steel. The bottom is

connected to the foundation with anchor bolts, and the top is connected to the frame beam.​

Frame beam: Withstands vertical loads on the floor or platform and transfers them to the frame columns. H-shaped steel is mostly used

and connected to the frame columns by welding or high-strength bolts to form rigid or semi-rigid joints.

The beam span is generally 6 - 12 meters, which is determined by equipment layout and process requirements.​

support system Horizontal support: arranged on the plane of the frame beam, divided into rigidity and flexibility. Rigid supports such as

crosses and chevron supports resist horizontal wind loads, earthquake actions and horizontal forces from equipment vibration and

are transmitted to the foundation; flexible supports use round steel or steel strands to limit horizontal displacement by tension.​

Vertical support: Located between frame columns to improve the vertical stability of the frame and prevent out-of-plane instability of the

frame columns. The form is similar to horizontal support and together form a stable spatial stress system.​

node is connected Connection methods: There are welding, high-strength bolts, and mixed connection of welding and high-strength bolts.​

Characteristics: Good welding integrity and high rigidity, but it is difficult to control on-site construction quality, which is prone to residual

stress and deformation; high-strength bolts are convenient to construction, removable and reliable under stress;

hybrid connection combines the advantages of the two and is selected according to the stress characteristics of different parts.​

Product Advantages

High strength and light weight: Steel has higher strength and lower density. Compared with traditional concrete structures, the dead weight of steel structural frames is lighter under the same load. This not only reduces the bearing pressure of the foundation, reduces the cost and construction difficulty of the foundation project, but also facilitates transportation and installation. For example, in some large petrochemical projects, the use of steel structural frames can greatly reduce the weight of the entire device, which is particularly important for projects built on soft soil foundations.

Product Application

Reaction towers: In production processes such as petroleum refining and chemical synthesis, many reactions need to be carried out at specific heights and spaces. High-rise steel structural frames are used to support various reaction towers, such as catalytic cracking towers in refineries, cracked gas separation towers in ethylene units, etc. These reaction towers are often of high height, large diameter, and carry complex chemical reactions and material transfer processes internally. With its high carrying capacity and stability, the steel structural frame can provide reliable support for the reaction tower and ensure the smooth progress of the reaction. Large-scale equipment support: Large compressors, pumps and other equipment in petrochemical production usually need to be installed on a platform at a certain height to facilitate material transportation, operation and maintenance. The high-rise steel structure frame can build a multi-story platform structure, and these equipment can be reasonably arranged at different heights to achieve smooth connection of the process flow. For example, in natural gas processing plants, large compressor units are often installed on second-or three-story platforms supported by steel structural frames to facilitate pipeline connections and equipment maintenance.
