Refinery Spring Support

The process pipeline systems of refineries usually face extreme working condition challenges: high temperature and high pressure, flammable and explosive media with highly corrosive substances. During unit start-up, shutdown and daily operation, if the huge displacement of pipelines caused by thermal expansion and contraction cannot be reasonably released, it will easily lead to flange leakage and even equipment damage. Backed by 14 years of technical accumulation in the pipeline support field, Yangzhou Tianshun Pipeline Technology Co., Ltd. has specially developed Refinery Spring Support for refining units. Through a precise elastic compensation mechanism, this product effectively absorbs the thermal displacement of pipeline systems, controls additional stress within a safe range, and ensures long-term and leak-free operation of refining units.

Core Technology and Parameter Matrix

Targeting the complex and diverse pipeline layouts of refineries, our Refinery Spring Support provides highly customized mechanical solutions. Its core technical parameters are as follows:

Engineering Adaptability and On-Site Operation & Maintenance

Refineries usually have the characteristics of compact space and dense pipelines. When designing Refinery Spring Support, we fully combined the practical pain points of refining engineering:

Compact and modular design: Provide multiple installation types including suspension (Type A/B/C) and support (Type D/E/F), with compact structure, which can perfectly adapt to narrow pipe gallery space and reduce on-site construction difficulty.

Visual condition monitoring: Equipped with high-precision displacement indicator plates and load scales, on-site operation and maintenance personnel can intuitively judge whether the pipeline is at the designed working position without disassembling the shell, facilitating preventive inspection without shutdown.

Cold-state locking and fast setting: Pre-compression locking is strictly carried out according to the pipeline system stress calculation report before delivery. During on-site installation, only simple thread fine-tuning and rooting fixation are required to reach the designed stress state, greatly shortening the unit maintenance and construction cycle.

Strict Quality Control and Manufacturing Standards

Refining units have extreme requirements for safety. As a key line of defense for pipeline system safety, the entire production process of Refinery Spring Support follows strict quality control standards:

Non-destructive testing and mechanical testing: All load-bearing welds and key stress components undergo appearance inspection and non-destructive testing (radiographic/ultrasonic testing) in accordance with relevant national standards to ensure foolproof structural strength.

Fatigue life verification: Spring components undergo strict fatigue tests and heat treatment processes to ensure no plastic deformation or fracture occurs during hundreds of thousands of thermal alternating cycles.

Factory locking and protection: Each unit is equipped with a positioning pin before delivery, locking the lever or spring at the cold-state working position to prevent irreversible damage to the spring caused by accidental displacement during transportation and hoisting.
